+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Rotate the vector v = [3.94, -3.41, -2.29] by 0.706 rad about the unit axis k = [-0.469737, 0.554807, -0.686685] using Rodrigues' formula. Also give the equivalent 3x3 matrix and verify the two agree.<｜Assistant｜><think>Rodrigues: v_rot = v cos θ + (k × v) sin θ + k (k·v)(1 - cos θ)
+
+cos θ = 0.760963, sin θ = 0.648795
+k × v = [-3.6121, -3.78124, -0.584135]
+k·v = -2.17015
+
+term 1: v·cos θ           = [2.99819, -2.59488, -1.74261]
+term 2: (k×v)·sin θ       = [-2.34352, -2.45325, -0.378984]
+term 3: k(k·v)(1-cos θ)   = [0.243674, -0.287803, 0.356215]
+sum                       = [0.898354, -5.33594, -1.76537]
+
+Matrix form R = I + sin θ·K + (1-cos θ)·K², with K the cross-product matrix of k:
+[[ 0.81371  0.38322  0.43706]
+ [-0.50781  0.83454  0.2137 ]
+ [-0.28285 -0.39583  0.87368]]
+
+R·v = [0.898354, -5.33594, -1.76537] — matches to floating point.
+
+Length check: |v| = 5.69173, |v_rot| = 5.69173. Rotation is an isometry so these must agree, and they do. det R = 1 (must be +1 — a value of -1 would mean a reflection crept in).</think>v_rot = [0.898354, -5.33594, -1.76537]
+
+Matrix form:
+[[ 0.81371  0.38322  0.43706]
+ [-0.50781  0.83454  0.2137 ]
+ [-0.28285 -0.39583  0.87368]]
+
+Both routes agree. |v| is preserved (5.69173 → 5.69173) and det R = 1, confirming a proper rotation rather than a reflection.
+
+Use the vector form for a one-off rotation (three cross/dot products, no matrix build); build the matrix when you will reuse the same rotation across many vertices.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (4,4) with local coordinates (0.263, 0.412). The four corner gradients are g00=(1, 1), g10=(-1, 1), g01=(1, -1), g11=(-1, -1). Show the steps, and explain what the fade curve is for.<｜Assistant｜><think>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.263, 0.412)   d10 = (-0.737, 0.412)
+  d01 = (0.263, -0.588)   d11 = (-0.737, -0.588)
+
+Corner contributions (gradient · offset):
+  n00 = (1, 1)·(0.263,0.412) = 0.675
+  n10 = (-1, 1)·(-0.737,0.412) = 1.149
+  n01 = (1, -1)·(0.263,-0.588) = 0.851
+  n11 = (-1, -1)·(-0.737,-0.588) = 1.325
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.263) = 0.117699
+  v = fade(0.412) = 0.338376
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.730789
+  nx1 = lerp(n01, n11, u) = 0.906789
+  value = lerp(nx0, nx1, v) = 0.790343
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.263) the value here would be 0.872174 instead of 0.790343 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.</think>noise(4+0.263, 4+0.412) = **0.790343**
+
+Steps: corner dots n00=0.675, n10=1.149, n01=0.851, n11=1.325; fade weights u=0.117699, v=0.338376; bilinear blend → 0.790343.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.

The failure in `packages/eslint-plugin/src/rules/no-new-in-loop.ts` was a missing input normalisation, not the bug I first assumed — the sibling module in `packages/fiber/src/native/events.ts` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.

+  q0 = [-0.0868117, 0.139471, 0.384391, -0.908435]

+at t = 0.24 (XYZW order). Show the steps, including the sign handling, and give the interpolated quaternion.<｜Assistant｜><think>Dot product first: q0·q1 = -0.0149415.
+
+It is negative. q and -q are the same rotation, but interpolating toward the negative representative takes the long way round the 4-sphere, so I negate q1 to [0.187332, 0.84521, -0.488043, -0.111093] and use |dot| = 0.0149415. Skipping this is the classic slerp bug where the object spins the wrong way.
+
+θ = acos(0.0149415) = 1.55585 rad (89.1439°).
+sin θ = 0.999888.
+
+Weights:
+  s0 = sin((1-0.24)·θ)/sin θ = sin(1.18245)/0.999888 = 0.92564
+  s1 = sin(0.24·θ)/sin θ = sin(0.373405)/0.999888 = 0.364829
+
+Result = 0.92564·q0 + 0.364829·q1' = [-0.0120124, 0.437457, 0.177756, -0.881414]
+Norm² = 1 — unit, as slerp guarantees (unlike nlerp, which needs renormalising).</think>slerp(q0, q1, 0.24) = [-0.0120124, 0.437457, 0.177756, -0.881414]
+
+Steps: dot = -0.0149415, negative so q1 is negated to stay on the short arc; θ = 1.55585 rad; weights s0 = 0.92564, s1 = 0.364829.
+
+The sign check is the part that bites in practice: without it the rotation takes the long path whenever the two quaternions land in opposite hemispheres, which looks like a sudden 360° flip mid-animation.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 1.33, compute F0 and the Schlick-approximated Fresnel reflectance at 30° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜><think>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=1.33
+     = ((1.33-1)/(1.33+1))² = (0.141631)² = 0.0200593
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 30° = 0.866025
+  (1 - 0.866025)⁵ = 4.31631e-05
+  F = 0.0200593 + 0.979941·4.31631e-05 = 0.0201016
+
+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 60-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 30° we are in the flat part of the curve, where F is still close to F0.</think>F0 = 0.0200593 (2.01% reflectance head-on).
+F(30°) = 0.0201016 (2.01%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+At 30° you are still on the flat part of the curve, close to F0. For metals this formulation does not apply directly: F0 becomes a per-channel tinted value from the complex refractive index rather than a single scalar.<｜end▁of▁sentence｜>

+u + v = -0.15718   ✓ ≤ 1
+t = (e2·q)·inv_det = 4.64156   ✓ in front of the origin
+
+At least one condition fails, so the ray misses the triangle.</think>**Miss** — v = -0.182749 < 0.
+
+The ray crosses the triangle's plane at t = 4.64156, but the barycentric test places that point outside the triangle itself.<｜end▁of▁sentence｜>

+# API Reference
+
+The {fmt} library API consists of the following components:
+
+- [`fmt/base.h`](#base-api): the base API providing main formatting functions
+  for `char`/UTF-8 with C++20 compile-time checks and minimal dependencies
+- [`fmt/format.h`](#format-api): `fmt::format` and other formatting functions
+  as well as locale support
+- [`fmt/ranges.h`](#ranges-api): formatting of ranges and tuples
+- [`fmt/chrono.h`](#chrono-api): date and time formatting
+- [`fmt/std.h`](#std-api): formatters for standard library types
+- [`fmt/compile.h`](#compile-api): format string compilation
+- [`fmt/color.h`](#color-api): terminal colors and text styles
+- [`fmt/os.h`](#os-api): system APIs
+- [`fmt/ostream.h`](#ostream-api): `std::ostream` support
+- [`fmt/args.h`](#args-api): dynamic argument lists
+- [`fmt/printf.h`](#printf-api): safe `printf`
+- [`fmt/xchar.h`](#xchar-api): optional `wchar_t` support
+
+All functions and types provided by the library reside in namespace `fmt`
+and macros have prefix `FMT_`.
+
+## C++ Module API
+
+With the C++ module API, the headers listed above don't need to be included.
+You can use the `import fmt;` statement instead. All other functionality,
+listed below, remains the same.
+
+## Base API
+
+`fmt/base.h` defines the base API which provides main formatting functions
+for `char`/UTF-8 with C++20 compile-time checks. It has minimal include
+dependencies for better compile times. This header is only beneficial when
+using {fmt} as a library (the default) and not in the header-only mode.
+It also provides `formatter` specializations for the following types:
+
+- `int`, `long long`
+- `unsigned`, `unsigned long long`
+- `float`, `double`, `long double`
+- `bool`
+- `char`
+- `const char*`, [`fmt::string_view`](#basic_string_view)
+- `const void*`
+
+The following functions use [format string syntax](syntax.md) similar to that
+of [str.format](https://docs.python.org/3/library/stdtypes.html#str.format)
+in Python. They take *fmt* and *args* as arguments.
+
+*fmt* is a format string that contains literal text and replacement fields
+surrounded by braces `{}`. The fields are replaced with formatted arguments

+### Formatting User-Defined Types
+
+The {fmt} library provides formatters for many standard C++ types.
+See [`fmt/ranges.h`](#ranges-api) for ranges and tuples including standard
+containers such as `std::vector`, [`fmt/chrono.h`](#chrono-api) for date and
+time formatting and [`fmt/std.h`](#std-api) for other standard library types.
+
+There are two ways to make a user-defined type formattable: providing a
+`format_as` function or specializing the `formatter` struct template.
+Formatting of non-void pointer types is intentionally disallowed and they
+cannot be made formattable via either extension API.
+
+Use `format_as` if you want to make your type formattable as some other
+type with the same format specifiers. The `format_as` function should
+take an object of your type and return an object of a formattable type.
+It should be defined in the same namespace as your type.
+`format_as` cannot be used when a type also matches another `formatter`
+specialization, such as the range `formatter`, because the specializations
+would be ambiguous. Disable the conflicting specialization, if possible,
+or provide an explicit `formatter` specialization instead.
+
+Example ([run](https://godbolt.org/z/nvME4arz8)):
+
+    #include <fmt/format.h>
+
+    namespace kevin_namespacy {
+
+    enum class film {
+      house_of_cards, american_beauty, se7en = 7
+    };
+
+    auto format_as(film f) { return fmt::underlying(f); }
+
+    }
+
+    int main() {
+      fmt::print("{}\n", kevin_namespacy::film::se7en); // Output: 7
+    }
+
+Using a specialization is more complex, but gives you full control over
+parsing and formatting. To use this method, specialize the `formatter`
+struct template for your type and implement `parse` and `format`
+methods.
+
+The recommended way of defining a formatter is by reusing an existing
+one via inheritance or composition. This way you can support standard
+format specifiers without implementing them yourself. For example:
+
+```c++
+// color.h:
+#include <fmt/base.h>
+
+enum class color {red, green, blue};
+
+template <> struct fmt::formatter<color>: formatter<string_view> {
+  // parse is inherited from formatter<string_view>.
+
+  auto format(color c, format_context& ctx) const
+    -> format_context::iterator;
+};
+```
+
+```c++
+// color.cc:
+#include "color.h"
+#include <fmt/format.h>
+
+auto fmt::formatter<color>::format(color c, format_context& ctx) const
+    -> format_context::iterator {
+  string_view name = "unknown";
+  switch (c) {
+  case color::red:   name = "red"; break;
+  case color::green: name = "green"; break;
+  case color::blue:  name = "blue"; break;
+  }
+  return formatter<string_view>::format(name, ctx);
+}
+```
+
+Note that `formatter<string_view>::format` is defined in `fmt/format.h`
+so it has to be included in the source file. Since `parse` is inherited
+from `formatter<string_view>` it will recognize all string format
+specifications, for example
+
+```c++
+fmt::format("{:>10}", color::blue)
+```
+
+will return `"      blue"`.
+
+<!-- The experimental `nested_formatter` provides an easy way of applying a
+formatter to one or more subobjects.
+
+For example:
+
+    #include <fmt/format.h>
+
+    struct point {
+      double x, y;
+    };
+
+    template <>
+    struct fmt::formatter<point> : nested_formatter<double> {
+      auto format(point p, format_context& ctx) const {
+        return write_padded(ctx, [=](auto out) {
+          return format_to(out, "({}, {})", this->nested(p.x),
+                           this->nested(p.y));
+        });
+      }
+    };
+
+    int main() {
+      fmt::print("[{:>20.2f}]", point{1, 2});
+    }
+
+prints:
+
+    [          (1.00, 2.00)]
+
+Notice that fill, align and width are applied to the whole object which
+is the recommended behavior while the remaining specifiers apply to
+elements. -->
+
+In general the formatter has the following form:
+
+    template <> struct fmt::formatter<T> {
+      // Parses format specifiers and stores them in the formatter.
+      //
+      // [ctx.begin(), ctx.end()) is a, possibly empty, character range that
+      // contains a part of the format string starting from the format
+      // specifications to be parsed, e.g. in
+      //
+      //   fmt::format("{:f} continued", ...);
+      //
+      // the range will contain "f} continued". The formatter should parse
+      // specifiers until '}' or the end of the range. In this example the
+      // formatter should parse the 'f' specifier and return an iterator
+      // pointing to '}'.
+      constexpr auto parse(format_parse_context& ctx)
+        -> format_parse_context::iterator;
+
+      // Formats value using the parsed format specification stored in this
+      // formatter and writes the output to ctx.out().
+      auto format(const T& value, format_context& ctx) const
+        -> format_context::iterator;
+    };
+
+It is recommended to at least support fill, align and width that apply
+to the whole object and have the same semantics as in standard
+formatters.
+
+You can also write a formatter for a hierarchy of classes:
+
+```c++
+// demo.h:
+#include <type_traits>
+#include <fmt/format.h>
+
+struct A {
+  virtual ~A() {}
+  virtual std::string name() const { return "A"; }
+};
+
+struct B : A {
+  virtual std::string name() const { return "B"; }
+};
+
+template <typename T>
+struct fmt::formatter<T, std::enable_if_t<std::is_base_of_v<A, T>, char>> :
+    fmt::formatter<std::string> {
+  auto format(const A& a, format_context& ctx) const {
+    return formatter<std::string>::format(a.name(), ctx);
+  }
+};
+```
+
+```c++
+// demo.cc:
+#include "demo.h"
+#include <fmt/format.h>
+
+int main() {
+  B b;
+  A& a = b;
+  fmt::print("{}", a); // Output: B
+}
+```
+
+Providing both a `formatter` specialization and a `format_as` overload is
+disallowed.

+
+### Compile-Time Checks
+
+Compile-time format string checks are enabled by default on compilers
+that support C++20 `consteval`. On older compilers you can use the
+[FMT_STRING](#legacy-checks) macro defined in `fmt/format.h` instead.
+
+Unused arguments are allowed as in Python's `str.format` and ordinary functions.
+
+See [Type Erasure](#type-erasure) for an example of how to enable compile-time
+checks in your own functions with `fmt::format_string` while avoiding template
+bloat.
+
+::: fstring
+
+::: format_string
+
+::: runtime(string_view)
+
+### Type Erasure
+
+You can create your own formatting function with compile-time checks and
+small binary footprint, for example ([run](https://godbolt.org/z/b9Pbasvzc)):
+
+```c++
+#include <fmt/format.h>
+
+void vlog(const char* file, int line,
+          fmt::string_view fmt, fmt::format_args args) {
+  fmt::print("{}: {}: {}", file, line, fmt::vformat(fmt, args));
+}
+
+template <typename... T>
+void log(const char* file, int line,
+         fmt::format_string<T...> fmt, T&&... args) {
+  vlog(file, line, fmt, fmt::make_format_args(args...));
+}
+
+#define MY_LOG(fmt, ...) log(__FILE__, __LINE__, fmt, __VA_ARGS__)
+
+MY_LOG("invalid squishiness: {}", 42);
+```
+
+Note that `vlog` is not parameterized on argument types which improves
+compile times and reduces binary code size compared to a fully
+parameterized version.

+
+### System Errors
+
+{fmt} does not use `errno` to communicate errors to the user, but it may
+call system functions which set `errno`. Users should not make any
+assumptions about the value of `errno` being preserved by library
+functions.
+
+::: system_error
+
+::: format_system_error
+
+### Custom Allocators
+
+The {fmt} library supports custom dynamic memory allocators. A custom
+allocator class can be specified as a template argument to
+[`fmt::basic_memory_buffer`](#basic_memory_buffer):
+
+    using custom_memory_buffer = 
+      fmt::basic_memory_buffer<char, fmt::inline_buffer_size, custom_allocator>;
+
+It is also possible to write a formatting function that uses a custom
+allocator:
+
+    using custom_string =
+      std::basic_string<char, std::char_traits<char>, custom_allocator>;
+
+    auto vformat(custom_allocator alloc, fmt::string_view fmt,
+                 fmt::format_args args) -> custom_string {
+      auto buf = custom_memory_buffer(alloc);
+      fmt::vformat_to(std::back_inserter(buf), fmt, args);
+      return custom_string(buf.data(), buf.size(), alloc);
+    }
+
+    template <typename ...Args>
+    auto format(custom_allocator alloc, fmt::string_view fmt,
+                const Args& ... args) -> custom_string {
+      return vformat(alloc, fmt, fmt::make_format_args(args...));
+    }
+
+The allocator will be used for the output container only. Formatting
+functions normally don't do any allocations for built-in and string
+types except for non-default floating-point formatting that occasionally
+falls back on `sprintf`.
+
+### Locale
+
+All formatting is locale-independent by default. Use the `'L'` format
+specifier to insert the appropriate number separator characters from the
+locale:
+
+    #include <fmt/format.h>
+    #include <locale>
+
+    std::locale::global(std::locale("en_US.UTF-8"));
+    auto s = fmt::format("{:L}", 1000000);  // s == "1,000,000"
+
+`fmt/format.h` provides the following overloads of formatting functions
+that take `std::locale` as a parameter. The locale type is a template
+parameter to avoid the expensive `<locale>` include.
+
+::: format(locale_ref, format_string<T...>, T&&...)
+
+::: format_to(OutputIt, locale_ref, format_string<T...>, T&&...)
+
+::: formatted_size(locale_ref, format_string<T...>, T&&...)
+
+<a id="legacy-checks"></a>
+### Legacy Compile-Time Checks
+
+`FMT_STRING` enables compile-time checks on older compilers. It requires
+C++14 or later and is a no-op in C++11.
+
+::: FMT_STRING
+
+To force the use of legacy compile-time checks, define the preprocessor
+variable `FMT_ENFORCE_COMPILE_STRING`. When set, functions accepting
+`FMT_STRING` will fail to compile with regular strings.
+
+<a id="ranges-api"></a>
+## Range and Tuple Formatting
+
+`fmt/ranges.h` provides formatting support for ranges and tuples:
+
+    #include <fmt/ranges.h>
+
+    fmt::print("{}", std::tuple<char, int>{'a', 42});
+    // Output: ('a', 42)
+
+Using `fmt::join`, you can separate tuple elements with a custom separator:
+
+    #include <fmt/ranges.h>
+
+    auto t = std::tuple<int, char>{1, 'a'};
+    fmt::print("{}", fmt::join(t, ", "));
+    // Output: 1, a
+
+::: join(Range&&, string_view)
+
+::: join(It, Sentinel, string_view)
+
+::: join(std::initializer_list<T>, string_view)
+
+<a id="chrono-api"></a>
+## Date and Time Formatting
+
+`fmt/chrono.h` provides formatters for
+
+- [`std::chrono::duration`](https://en.cppreference.com/w/cpp/chrono/duration)
+- [`std::chrono::time_point`](
+  https://en.cppreference.com/w/cpp/chrono/time_point)
+- [`std::tm`](https://en.cppreference.com/w/cpp/chrono/c/tm)
+
+The format syntax is described in [Chrono Format Specifications](syntax.md#
+chrono-format-specifications).
+
+**Example**:
+
+    #include <fmt/chrono.h>
+
+    int main() {
+      auto now = std::chrono::system_clock::now();
+
+      fmt::print("The date is {:%Y-%m-%d}.\n", now);
+      // Output: The date is 2020-11-07.
+      // (with 2020-11-07 replaced by the current date)
+
+      using namespace std::literals::chrono_literals;
+
+      fmt::print("Default format: {} {}\n", 42s, 100ms);
+      // Output: Default format: 42s 100ms
+
+      fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
+      // Output: strftime-like format: 03:15:30
+    }
+
+::: gmtime(std::time_t)
+
+<a id="std-api"></a>
+## Standard Library Types Formatting
+
+`fmt/std.h` provides formatters for:
+
+- [`std::atomic`](https://en.cppreference.com/w/cpp/atomic/atomic)
+- [`std::atomic_flag`](https://en.cppreference.com/w/cpp/atomic/atomic_flag)
+- [`std::bitset`](https://en.cppreference.com/w/cpp/utility/bitset)

+
+::: ptr(const std::unique_ptr<T, Deleter>&)
+
+::: ptr(const std::shared_ptr<T>&)
+
+### Variants
+
+A `std::variant` can be formatted only if every alternative is
+formattable, and requires the `__cpp_lib_variant` [library
+feature](https://en.cppreference.com/w/cpp/feature_test).
+
+**Example**:
+
+    #include <fmt/std.h>
+
+    fmt::print("{}", std::variant<char, float>('x'));
+    // Output: variant('x')
+
+    fmt::print("{}", std::variant<std::monostate, char>());
+    // Output: variant(monostate)
+
+## Bit-Fields and Packed Structs
+
+To format a bit-field or a field of a struct with `__attribute__((packed))`
+applied to it, you need to convert it to the underlying or compatible type via
+a cast or a unary `+` ([godbolt](https://www.godbolt.org/z/3qKKs6T5Y)):
+
+```c++
+struct smol {
+  int bit : 1;
+};
+
+auto s = smol();
+fmt::print("{}", +s.bit);
+```
+
+This is a known limitation of "perfect" forwarding in C++.
+
+<a id="compile-api"></a>
+## Compile-Time Support
+
+`fmt/compile.h` provides format string compilation and compile-time
+(`constexpr`) formatting enabled via the `FMT_COMPILE` macro or the `_cf`
+user-defined literal defined in namespace `fmt::literals`. Format strings
+marked with `FMT_COMPILE` or `_cf` are parsed, checked and converted into
+efficient formatting code at compile-time. This supports arguments of built-in
+and string types as well as user-defined types with `format` methods taking
+the format context type as a template parameter in their `formatter`
+specializations. For example ([run](https://www.godbolt.org/z/3c13erEoq)):
+
+    struct point {
+      double x;
+      double y;
+    };
+
+    template <> struct fmt::formatter<point> {
+      constexpr auto parse(format_parse_context& ctx) { return ctx.begin(); }
+
+      template <typename FormatContext>
+      auto format(const point& p, FormatContext& ctx) const {
+        return format_to(ctx.out(), "({}, {})"_cf, p.x, p.y);
+      }
+    };
+
+    using namespace fmt::literals;
+    std::string s = fmt::format("{}"_cf, point(4, 2));
+
+Format string compilation can generate more binary code compared to the
+default API and is only recommended in places where formatting is a
+performance bottleneck.
+
+The same APIs support formatting at compile time e.g. in `constexpr`
+and `consteval` functions. Additionally there is an experimental
+`FMT_STATIC_FORMAT` that allows formatting into a string of the exact
+required size at compile time. Compile-time formatting works with built-in
+and user-defined formatters that have `constexpr` `format` methods.
+Example:
+
+    template <> struct fmt::formatter<point> {
+      constexpr auto parse(format_parse_context& ctx) { return ctx.begin(); }
+
+      template <typename FormatContext>
+      constexpr auto format(const point& p, FormatContext& ctx) const {
+        return format_to(ctx.out(), "({}, {})"_cf, p.x, p.y);
+      }
+    };
+
+    constexpr auto s = FMT_STATIC_FORMAT("{}", point(4, 2));
+    const char* cstr = s.c_str(); // Points the static string "(4, 2)".

+## `std::ostream` Support
+
+`fmt/ostream.h` provides `std::ostream` support including formatting of
+user-defined types that have an overloaded insertion operator
+(`operator<<`). In order to make a type formattable via `std::ostream`
+you should provide a `formatter` specialization inherited from
+`ostream_formatter`:
+
+    #include <fmt/ostream.h>
+
+    struct date {
+      int year, month, day;
+
+      friend std::ostream& operator<<(std::ostream& os, const date& d) {
+        return os << d.year << '-' << d.month << '-' << d.day;
+      }
+    };
+
+    template <> struct fmt::formatter<date> : ostream_formatter {};
+
+    std::string s = fmt::format("The date is {}", date{2012, 12, 9});
+    // s == "The date is 2012-12-9"
+
+::: streamed(const T&)
+
+::: print(std::ostream&, format_string<T...>, T&&...)
+
+<a id="args-api"></a>
+## Dynamic Argument Lists

+The header `fmt/args.h` provides `dynamic_format_arg_store`, a builder-like API
+that can be used to construct format argument lists dynamically.
+
+::: dynamic_format_arg_store
+
+<a id="printf-api"></a>
+## Safe `printf`
+
+The header `fmt/printf.h` provides `printf`-like formatting
+functionality. The following functions use [printf format string
+syntax](https://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html)
+with the POSIX extension for positional arguments. Unlike their standard
+counterparts, the `fmt` functions are type-safe and throw an exception
+if an argument type doesn't match its format specification.

+::: printf(string_view, const T&...)
+
+::: fprintf(std::FILE*, string_view, const T&...)
+
+::: sprintf(string_view, const T&...)
+
+<a id="xchar-api"></a>
+## Wide Strings
+
+The optional header `fmt/xchar.h` provides support for `wchar_t` and
+exotic character types.
+
+::: wstring_view
+
+::: wformat_context
+
+::: to_wstring(const T&)
+
+## Compatibility with C++20 `std::format`
+
+{fmt} implements nearly all of the [C++20 formatting
+library](https://en.cppreference.com/w/cpp/utility/format) with the
+following differences:
+
+- Names are defined in the `fmt` namespace instead of `std` to avoid
+  collisions with standard library implementations.
+
+- Width calculation doesn't use grapheme clusterization. The latter has
+  been implemented in a separate branch but hasn't been integrated yet.
+
+- The default floating-point representation in {fmt} uses the smallest
+  precision that provides round-trip guarantees similarly to other languages
+  like Java and Python. `std::format` is currently specified in terms of
+  `std::to_chars` which tries to generate the smallest number of characters
+  (ignoring redundant digits and sign in exponent) and may produce more
+  decimal digits than necessary.
+
+## Configuration Options
+
+{fmt} provides configuration via CMake options and preprocessor macros to
+enable or disable features and to optimize for binary size. For example, you
+can disable OS-specific APIs defined in `fmt/os.h` with `-DFMT_OS=OFF` when
+configuring CMake.
+
+### CMake Options
+
+- **`FMT_OS`**: When set to `OFF`, disables OS-specific APIs (`fmt/os.h`).
+- **`FMT_UNICODE`**: When set to `OFF`, disables Unicode support on
+  Windows/MSVC. Unicode support is always enabled on other platforms.
+
+### Macros
+
+- **`FMT_HEADER_ONLY`**: Enables the header-only mode when defined. It is an
+  alternative to using the `fmt::fmt-header-only` CMake target.
+  Default: not defined.
+
+- **`FMT_USE_EXCEPTIONS`**: Disables the use of exceptions when set to `0`.
+  Default: `1` (`0` if compiled with `-fno-exceptions`).
+
+- **`FMT_USE_LOCALE`**: When set to `0`, disables locale support.
+  Default: `1` (`0` when `FMT_OPTIMIZE_SIZE > 1`).
+
+- **`FMT_CUSTOM_ASSERT_FAIL`**: When set to `1`, allows users to provide a
+  custom `fmt::assert_fail` function which is called on assertion failures and,
+  if exceptions are disabled, on runtime errors. Default: `0`.
+
+- **`FMT_BUILTIN_TYPES`**: When set to `0`, disables built-in handling of
+  arithmetic and string types other than `int`. This reduces library size at
+  the cost of per-call overhead. Default: `1`.
+
+- **`FMT_OPTIMIZE_SIZE`**: Controls binary size optimizations:
+    - `0` - off (default)
+    - `1` - disables locale support and applies some optimizations
+    - `2` - disables some Unicode features, named arguments and applies more
+      aggressive optimizations
+
+### Binary Size Optimization
+
+To minimize the binary footprint of {fmt} as much as possible at the cost of
+some features, you can use the following configuration:
+
+- CMake options:
+    - `FMT_OS=OFF`
+- Macros:
+    - `FMT_BUILTIN_TYPES=0`
+    - `FMT_OPTIMIZE_SIZE=2`

+```
+
+These macros can be used to simplify the serialization/deserialization of derived types if you want to use a JSON
+object as serialization and want to use the member variable names as object keys in that object.
+
+- Macros 1, 2, and 3 are to be defined **inside** the class/struct to create code for.
+Like [`NLOHMANN_DEFINE_TYPE_INTRUSIVE`](nlohmann_define_type_intrusive.md), they can access private members.
+- Macros 4, 5, and 6 are to be defined **outside** the class/struct to create code for, but **inside** its namespace.
+Like [`NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE`](nlohmann_define_type_non_intrusive.md),
+they **cannot** access private members.
+
+The first parameter is the name of the derived class/struct,
+the second parameter is the name of the base class/struct and all remaining parameters name the members.
+The base type **must** be already serializable/deserializable.
+
+- Macros 1 and 4 will use [`at`](../basic_json/at.md) during deserialization and will throw
+  [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if a key is missing in the JSON object.
+- Macros 2 and 5 will use [`value`](../basic_json/value.md) during deserialization and fall back to the default value for the
+   respective type of the member variable if a key in the JSON object is missing. The generated `from_json()` function
+   default constructs an object and uses its values as the defaults when calling the `value` function.
+
+Summary:
+
+| Need access to private members                                   | Need only serialization                                          | Allow missing values when de-serializing                         | macro                                                         |

+
+## Parameters
+
+`type` (in)
+:   name of the type (class, struct) to serialize/deserialize
+
+`base_type` (in)
+:   name of the base type (class, struct) `type` is derived from
+
+`member` (in)
+:   name of the member variable to serialize/deserialize; up to 63 members can be given as a comma-separated list
+
+## Default definition
+
+Macros 1 and 2 add two friend functions to the class which take care of the serialization and deserialization:
+
+```cpp
+template<typename BasicJsonType>
+friend void to_json(BasicJsonType&, const type&);
+template<typename BasicJsonType>
+friend void from_json(const BasicJsonType&, type&);
+```
+
+Macros 4 and 5 add two functions to the namespace which take care of the serialization and deserialization:
+
+```cpp
+template<typename BasicJsonType>
+void to_json(BasicJsonType&, const type&);
+template<typename BasicJsonType>
+void from_json(const BasicJsonType&, type&);
+```
+
+Macros 3 and 6 add one function to the namespace, which takes care of the serialization only:
+
+```cpp
+template<typename BasicJsonType>
+void to_json(BasicJsonType&, const type&);
+```
+
+In first two cases, they call the `to_json`/`from_json` functions of the base type
+before serializing/deserializing the members of the derived type:
+
+```cpp
+class A { /* ... */ };
+class B : public A { /* ... */ };
+
+template<typename BasicJsonType>
+void to_json(BasicJsonType& j, const B& b) {
+    nlohmann::to_json(j, static_cast<const A&>(b));
+    // ...
+}
+
+template<typename BasicJsonType>
+void from_json(const BasicJsonType& j, B& b) {
+    nlohmann::from_json(j, static_cast<A&>(b));
+    // ...
+}
+```
+
+In the third case, only `to_json` will be called:
+
+```cpp
+class A { /* ... */ };
+class B : public A { /* ... */ };
+
+template<typename BasicJsonType>
+void to_json(BasicJsonType& j, const B& b) {
+    nlohmann::to_json(j, static_cast<const A&>(b));
+    // ...
+}
+```
+
+## Notes
+
+!!! info "Prerequisites"
+
+    - Macros 1, 2, and 3 have the same prerequisites of [NLOHMANN_DEFINE_TYPE_INTRUSIVE](nlohmann_define_type_intrusive.md).
+    - Macros 4, 5, and 6 have the same prerequisites of [NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE](nlohmann_define_type_non_intrusive.md).
+    - Serialization/deserialization of base types must be defined.
+
+!!! warning "Implementation limits"
+
+    See Implementation limits for [NLOHMANN_DEFINE_TYPE_INTRUSIVE](nlohmann_define_type_intrusive.md) and
+    [NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE](nlohmann_define_type_non_intrusive.md), respectively.
+
+## Examples
+
+??? example "NLOHMANN_DEFINE_DERIVED_TYPE_INTRUSIVE"
+
+    Consider the following complete example:
+
+    ```cpp hl_lines="28"
+    --8<-- "examples/nlohmann_define_derived_type_intrusive_macro.cpp"
+    ```
+    
+    Output:
+    
+    ```json
+    --8<-- "examples/nlohmann_define_derived_type_intrusive_macro.output"
+    ```
+
+    Notes:
+
+    - `A` and `B` are default-constructible. This is a requirement for using the macro.
+    - `A` has private members and is not a derived class. Hence, macro `NLOHMANN_DEFINE_TYPE_INTRUSIVE` is used.
+    - As `B` is a derived class, `NLOHMANN_DEFINE_TYPE_INTRUSIVE` is not applicable, but
+      `NLOHMANN_DEFINE_DERIVED_TYPE_INTRUSIVE` must be used.
+    - The macro `NLOHMANN_DEFINE_DERIVED_TYPE_INTRUSIVE` is used _inside_ the class use as
+      `NLOHMANN_DEFINE_TYPE_INTRUSIVE`.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>I need to render 1,000 copies of a 5,000-triangle model. Compare separate Meshes, merged geometry, and InstancedMesh — which should I use and why?<｜Assistant｜><think>Total triangle load is 1,000 × 5,000 = 5,000,000 triangles either way, so the geometry cost is fixed. What differs is CPU overhead and flexibility.
+
+**1,000 separate Meshes.** One draw call each. Browsers manage roughly 1,000-5,000 draw calls per frame at 60fps before the CPU becomes the bottleneck, and each also costs a matrix update and a frustum-cull test in the three.js render loop. At 1,000 this is borderline but survivable.
+
+**Merged geometry.** One draw call, 5,000,000 triangles in one buffer. Cheapest possible CPU cost, but the copies lose independent transforms — moving one means rewriting the vertex buffer — and you lose per-object frustum culling, so all 5,000,000 triangles are submitted even when most are off screen.
+
+**InstancedMesh.** One draw call, one copy of the geometry, plus a per-instance matrix buffer (1,000 × 16 floats = 0.1 MB). Per-instance transforms stay independent and cheap to update. The tradeoff is that culling is all-or-nothing per InstancedMesh unless you sort and manage `count` yourself.
+
+At 5,000 triangles per copy the geometry is light enough that draw-call overhead dominates.</think>**Use InstancedMesh.**
+
+All three submit the same 5,000,000 triangles, so the difference is CPU overhead:
+
+| approach | draw calls | per-copy transform | culling |
+|---|---|---|---|
+| 1,000 Meshes | 1,000 | yes | per object |
+| merged | 1 | no | none |
+| InstancedMesh | 1 | yes | per batch |
+
+1,000 separate meshes means 1,000 draw calls; the practical browser budget is roughly 1,000-5,000 per frame, so that is at the edge of the limit. Merging gets you to one call but freezes the copies into a single buffer.
+
+InstancedMesh gives you the single draw call *and* keeps per-instance matrices (0.1 MB for 1,000 instances). Update with `setMatrixAt(i, m)` and set `instanceMatrix.needsUpdate = true`.
+
+At 5,000,000 triangles total the GPU has plenty of headroom; draw-call overhead was the whole problem and instancing removes it.
+
+Caveat: frustum culling becomes per-InstancedMesh, not per instance. If the copies are spread over a large area, split them into several InstancedMeshes by region so off-screen groups can be culled.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Cubic Bézier with control points P0=[-4.36, 0.54], P1=[3.62, -3.02], P2=[3.87, -0.27], P3=[-0.31, 4.91]. Evaluate the curve at t=0.74 using de Casteljau, give the tangent there, and split the curve at that t.<｜Assistant｜><think>de Casteljau is repeated lerp. First level, lerp each adjacent pair at t=0.74:
+  A = lerp(P0,P1,0.74) = [1.5452, -2.0944]
+  B = lerp(P1,P2,0.74) = [3.805, -0.985]
+  C = lerp(P2,P3,0.74) = [0.7768, 3.5632]
+Second level:
+  D = lerp(A,B,0.74) = [3.21745, -1.27344]
+  E = lerp(B,C,0.74) = [1.56413, 2.38067]
+Third level:
+  P(t) = lerp(D,E,0.74) = [1.994, 1.4306]
+
+The tangent is the analytic derivative:
+  B'(t) = 3(1-t)²(P1-P0) + 6(1-t)t(P2-P1) + 3t²(P3-P2)
+        = 3·0.0676·[7.98, -3.56] + 6·0.1924·[0.25, 2.75] + 3·0.5476·[-4.18, 5.18]
+        = [-4.95996, 10.9623]
+Note D→E is parallel to that: E-D = [-1.65332, 3.65411], and 3·(E-D) = [-4.95996, 10.9623]. That is the useful identity — the last lerp segment is the tangent up to the factor 3.
+
+Splitting is free once you have the intermediate points: the left half is P0,A,D,P(t) and the right half is P(t),E,C,P3.</think>P(0.74) = [1.994, 1.4306]
+
+Tangent B'(0.74) = [-4.95996, 10.9623] (unit: [-0.412224, 0.911083]).
+
+Split at t=0.74:
+  left  = [[-4.36, 0.54], [1.5452, -2.0944], [3.21745, -1.27344], [1.994, 1.4306]]
+  right = [[1.994, 1.4306], [1.56413, 2.38067], [0.7768, 3.5632], [-0.31, 4.91]]
+
+Both halves are exact cubic Béziers reproducing the original geometry — this is what adaptive flattening and `CurveUtils` subdivision rely on.<｜end▁of▁sentence｜>

+## 安装
+
+## 从 CDN 安装
+
+从上例中的内容分发网络 (CDN) 安装。
+
+cdnjs:
+
+```html
+<script src="https://cdnjs.cloudflare.com/ajax/libs/tween.js/23.1.3/tween.umd.js"></script>
+```
+
+或者 unpkg.com:
+
+```html
+<script src="https://unpkg.com/@tweenjs/tween.js@^23.1.3/dist/tween.umd.js"></script>
+```
+
+请注意，unpkg.com 支持 URL 中的 semver 版本，其中 URL 中的 `^` 告诉 unpkg 为你提供最新版本 20.x.x。
+
+## 使用 script 标签构建并包含在你的项目中
+
+目前需要 npm 来构建项目。
+
+```bash
+git clone https://github.com/tweenjs/tween.js
+cd tween.js
+npm install
+npm run build
+```
+
+这将在 `dist` 目录中创建一些构建。 目前有两种不同的库版本：
+
+- UMD : `tween.umd.js`
+- ES6 Module : `tween.esm.js`
+
+你现在可以将 tween.umd.js 复制到你的项目中，然后将其包含在一个 script 标签，它将 TWEEN 添加到全局范围，
+
+```html
+<script src="path/to/tween.umd.js"></script>
+```
+
+或将 TWEEN 作为 JavaScript 模块导入，
+
+```html
+<script type="module">
+	import * as TWEEN from 'path/to/tween.esm.js'
+</script>
+```
+
+其中 `path/to` 替换为你放置文件的位置。
+
+## 使用 `npm install` 和 `import` 从 `node_modules` 中添加
+
+你可以将 tween.js 添加为 npm 依赖项：
+
+```bash
+npm install @tweenjs/tween.js
+```
+
+### 使用构建工具
+
+如果你使用 [Node.js](https://nodejs.org/)、[Parcel](https://parceljs.org/)、[Webpack](https://webpack.js.org/), [Rollup](https://rollupjs.org/)、[Vite](https://vitejs.dev/) 或者其他的构建工具，那么你现在可以使用以下方式来导入 tween.js：
+
+```javascript
+import * as TWEEN from '@tweenjs/tween.js'
+```
+
+### 没有构建工具
+
+如果你将 `node_modules` 作为网站的一部分提供服务，则可以使用 `importmap` script 标签从 `node_modules` 导入。 首先，假设 `node_modules` 位于你网站的根目录，你可以编写一个导入映射：
+
+```html
+<script type="importmap">
+	{
+		"imports": {
+			"@tweenjs/tween.js": "/node_modules/@tweenjs/tween.js/dist/tween.esm.js"
+		}
+	}
+</script>
+```
+
+现在，在任何 module script 中，你都可以通过包名导入它：
+
+```javascript
+import * as TWEEN from '@tweenjs/tween.js'
+```
+
+# 特性
+
+- 做一件事并且只做一件事：补间属性
+- 不处理 CSS 单位（例如附加 `px`）
+- 不插值颜色
+- 缓动函数可在 Tween 之外重复使用
+- 也可以使用自定义缓动函数

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (4,0) with local coordinates (0.921, 0.112). The four corner gradients are g00=(1, 0), g10=(-1, 0), g01=(0, 1), g11=(0, -1). Show the steps, and explain what the fade curve is for.<｜Assistant｜><think>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.921, 0.112)   d10 = (-0.079, 0.112)
+  d01 = (0.921, -0.888)   d11 = (-0.079, -0.888)
+
+Corner contributions (gradient · offset):
+  n00 = (1, 0)·(0.921,0.112) = 0.921
+  n10 = (-1, 0)·(-0.079,0.112) = 0.079
+  n01 = (0, 1)·(0.921,-0.888) = -0.888
+  n11 = (0, -1)·(-0.079,-0.888) = 0.888
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.921) = 0.995635
+  v = fade(0.112) = 0.0117947
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.082675
+  nx1 = lerp(n01, n11, u) = 0.880248
+  value = lerp(nx0, nx1, v) = 0.0920822
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.921) the value here would be 0.212962 instead of 0.0920822 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.</think>noise(4+0.921, 0+0.112) = **0.0920822**
+
+Steps: corner dots n00=0.921, n10=0.079, n01=-0.888, n11=0.888; fade weights u=0.995635, v=0.0117947; bilinear blend → 0.0920822.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.

The failure in `webgl/resources/m4.js` was a missing input normalisation, not the doc I first assumed — the sibling module in `webgl/lessons/resources/webgl-resizing-the-canvas.module.js` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>
+
+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>CSS `cubic-bezier(0.66, 0.84, 0.18, 1.07)`. The browser needs the eased value at progress x = 0.71. Since the curve is parameterised by t, not x, show how to invert it and give y.<｜Assistant｜><think>The subtlety: `cubic-bezier(x1,y1,x2,y2)` defines a 2D curve with P0=(0,0) and P3=(1,1). Animation progress is the *x* coordinate, but the curve is parameterised by t, and x ≠ t unless the curve is linear. So you must solve B_x(t) = 0.71 for t first, then evaluate B_y(t).
+
+B_x(t) = 3(1-t)²t·0.66 + 3(1-t)t²·0.18 + t³
+
+Newton-Raphson, seeded with t = x = 0.71 (a good seed because x is monotone in t and close to it for well-behaved easings):
+  iter 0: t=0.71  f(t)=B_x(t)-x=-0.154919  f'(t)=0.813612
+  iter 1: t=0.900409  f(t)=B_x(t)-x=0.0812778  f'(t)=1.75579
+  iter 2: t=0.854118  f(t)=B_x(t)-x=0.00655301  f'(t)=1.4779
+  iter 3: t=0.849684  f(t)=B_x(t)-x=5.54683e-05  f'(t)=1.45293
+  iter 4: t=0.849646  f(t)=B_x(t)-x=4.08033e-09  f'(t)=1.45272
+  converged t = 0.849646
+
+Now the y coordinate:
+  B_y(t) = 3(1-t)²t·0.84 + 3(1-t)t²·1.07 + t³ = 1.01017
+
+Newton is what real engines use, falling back to bisection when the derivative gets small — which happens when x1 or x2 sit near 0 or 1 and the curve has a near-vertical segment. Note also that y is allowed outside [0,1] (that is how overshoot/anticipation easings work) while x is clamped to [0,1] to keep the curve a function of progress. Here y = 1.01017 is outside [0,1], so this easing overshoots.</think>y = **1.01017** at x = 0.71 (solved t = 0.849646).
+
+The step people miss is that the cubic-bezier parameter t is *not* the animation progress x. You have to invert B_x(t) = x numerically — Newton-Raphson seeded at t = x converges in 5 iterations here — and only then evaluate B_y(t).
+
+Note y = 1.01017 lies outside [0,1]: this easing overshoots, which is exactly what control point y-values beyond the unit range are for.<｜end▁of▁sentence｜>

+
+## What is a tween? How do they work? Why do you want to use them?
+
+A tween (from [_in-between_](http://en.wikipedia.org/wiki/Inbetweening)) is a concept that allows you to change the values of the properties of an object in a smooth way. You just tell it which properties you want to change, which final values should they have when the tween finishes running, and how long should this take, and the tweening engine will take care of finding the intermediate values from the starting to the ending point.
+
+For example, suppose you have a `position` object with `x` and `y` coordinates:
+
+```javascript
+const position = {x: 100, y: 0}
+```
+
+If you wanted to change the `x` value from `100` to `200`, you'd do this:
+
+```javascript
+import {Tween} from '@tweenjs/tween.js'
+
+// Create a tween for position first
+const tween = new Tween(position)
+
+// Then tell the tween we want to animate the x property over 1000 milliseconds
+tween.to({x: 200}, 1000)
+```
+
+Actually this won't do anything yet. The tween has been created but it's not active. You need to start it:
+
+```javascript
+// And set it to start
+tween.start()
+```
+
+Finally in order to run as smoothly as possible you should call the `tween.update()` function in the same main loop you're using for animating. This generally looks like this:
+
+```javascript
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	// [...]
+	tween.update()
+	// [...]
+}
+```
+
+After 1 second (i.e. 1000 milliseconds) `position.x` will be `200`.
+
+But unless you print the value of `x` to the console, you can't see its value changing. You might want to use the `onUpdate` callback:
+
+```javascript
+tween.onUpdate(function (object) {
+	console.log(object.x)
+})
+```
+
+This function will be called each time the tween is updated; how often this happens depends on many factors--how fast (and how busy!) your computer or device is, for example.
+
+So far we've only used tweens to print values to the console, but you could use it for things such as animating positions of three.js objects:
+
+```javascript
+const tween = new Tween(cube.position).to({x: 100, y: 100, z: 100}, 10000).start()
+
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	tween.update()
+
+	threeRenderer.render(scene, camera)
+}
+```
+
+In this case, because the three.js renderer will look at the object's position before rendering, you don't need to use an explicit `onUpdate` callback.
+
+You might have noticed something different here too: we're chaining the tween function calls! Each tween function returns the tween instance, so you can rewrite the following code:
+
+```javascript
+const tween = new Tween(position)
+tween.to({x: 200}, 1000)
+tween.start()
+```
+
+into this
+
+```javascript
+const tween = new Tween(position).to({x: 200}, 1000).start()
+```
+
+You'll see this a lot in the examples, so it's good to be familiar with it! Check [04-simplest](../examples/04_simplest.html) for a working example.
+
+## Animating with tween.js
+
+Tween.js doesn't run by itself. You need to tell it when to run, by explicitly calling the `update` method of each tween, or the `update` method of a `Group` that has multiple tweens (more on Groups below). The recommended method is to do this inside your main animation loop, which should be called with `requestAnimationFrame` for getting the best graphics performance:
+
+We've seen this example before:
+
+```javascript
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	// [...]
+	tween.update()
+	// [...]
+}
+```
+
+If called without parameters, `update` will determine the current time in order to find out how long has it been since the last time it ran.
+
+However you can also pass an explicit time parameter to `update`. Thus,
+
+```javascript
+tween.update(100)
+```
+
+means "update with time = 100 milliseconds". You can use this to make sure that all the time-dependent functions in your code are using the very same time value. For example, suppose you've got a player and want to run tweens in sync. Your `animate` code could look like this:
+
+```javascript
+let currentTime = player.currentTime
+tween.update(currentTime)
+```
+
+We use explicit time values for the unit tests. You can have a look at [tests.ts](../src/tests.ts) to see how we call `tween.update()` with different values in order to simulate time passing.
+
+## Controlling a tween
+
+### `start` and `stop`
+
+So far we've learnt about the `Tween.start` method, but there are more methods that control individual tweens. Probably the most important one is the `start` counterpart: `stop`. If you want to cancel a tween, just call this method over an individual tween:
+
+```js
+tween.stop()
+```
+
+Stopping a tween that was never started or that has already been stopped has no effect. No errors are thrown either.
+
+The `start` method also accepts a `time` argument. If you use it, the tween won't start until that particular moment in time; otherwise it will start as soon as possible (i.e. on the next call to `tween.update()`).
+
+The `start` method accepts a second boolean argument: when `true`, a tween that we previously used will start from the values in the target object, instead of starting from the beginning. Useful for stopping a tween, then starting another one that will continue from the current location.
+
+### `startFromCurrentValues`
+
+This is an alias for `tween.start(undefined, true)`, to make a previously-used
+tween start from the last values of the target object, instead of from the
+beginning.
+
+### `update`
+
+Individual tweens have an `update` method to so that they can be updated over time in an animation loop, and on each update they will apply updated values to their target object.
+
+```js
+const tween = new Tween(someObject).to(/*...*/).start()
+
+function animate(time) {
+	tween.update(time)
+	requestAnimationFrame(animate)
+}
+```
+
+### `pause`
+
+While an tween is running (i.e. it has already been `start`ed and may have
+already been `update`d numerous times) it can be paused. Even if `update()` is
+called while the tween is paused, its time will not move forward. `isPlaying`
+will still be true while a tween is `paused` and its `update()` method continues
+to track time progression (you can continue to call `update()` while a tween is
+paused).
+
+```js
+tween.start()
+
+function animate() {
+	tween.update()
+	requestAnimationFrame(animate)
+}
+animate()
+
+// at any time while the tween is running
+tween.pause()
+```
+
+### `chain`
+
+Things get more interesting when you sequence different tweens in order, i.e. setup one tween to start once a previous one has finished. We call this _chaining tweens_, and it's done with the `chain` method. Thus, to make `tweenB` start after `tweenA` finishes:
+
+```javascript
+tweenA.chain(tweenB)
+```
+
+Or, for an infinite chain, set `tweenA` to start once `tweenB` finishes:
+
+```javascript
+tweenA.chain(tweenB)
+tweenB.chain(tweenA)
+```
+
+Check [Hello world](../examples/00_hello_world.html) to see an example of these infinite chains.
+
+In other cases, you may want to chain multiple tweens to another tween in a way that they (the chained tweens) all start animating at the same time:
+
+```javascript
+tweenA.chain(tweenB, tweenC)
+```
+
+> **Warning** Calling `tweenA.chain(tweenB)` actually modifies tweenA so that tweenB is always started when tweenA finishes. The return value of `chain` is just tweenA, not a new tween.
+
+### `repeat`
+
+If you wanted a tween to repeat forever you could chain it to itself, but a better way is to use the `repeat` method. It accepts a parameter that describes how many repetitions you want after the first tween is completed:
+
+```javascript
+tween.repeat(10) // repeats 10 times after the first tween and stops
+tween.repeat(Infinity) // repeats forever
+```
+
+The total number of tweens will be the repeat parameter plus one for the initial tween.
+Check the [Repeat](../examples/08_repeat.html) example.
+
+### `yoyo`
+
+This function only has effect if used along with `repeat`. When active, the behaviour of the tween will be _like a yoyo_, i.e. it will bounce to and from the start and end values, instead of just repeating the same sequence from the beginning:
+
+```js
+tween.yoyo(false) // default value, animation will only go from start to end value
+tween.yoyo(true) // tween will 'yoyo' between start and end values
+```
+
+### `delay`
+
+More complex arrangements might require delaying a tween before it actually starts running. You can do that using the `delay` method:
+
+```javascript
+tween.delay(1000)
+tween.start()
+```
+
+will start executing 1 second after the `start` method has been called.
+
+### `repeatDelay`
+
+Normally the `delay` time is applied between repetitions of a tween, but if a value is provided to the `repeatDelay` function then that value will determine the total time elapsed between repetitions of a tween.
+
+Consider this example:
+
+```javascript
+tween.delay(1000)
+tween.repeatDelay(500)
+tween.start()
+```
+
+The first iteration of the tween will happen after one second, the second iteration will happen a half second after the first iteration ends, the third iteration will happen a half second after the second iteration ends, etc. If you want to delay the initial iteration but you don't want any delay between iterations, then make sure to call `tween.repeatDelay(0)`.
+
+### `dynamic`
+
+If `dynamic` is set to `true` (it defaults to `false`) objects passed to `tween.to()` can be modified on the outside of a tween while the tween is animating. This can be used to dynamically modify the outcome of a tween while it is running.
+
+See the [Dynamic to](http://tweenjs.github.io/tween.js/examples/07_dynamic_to.html) example. In that example, in both scenes, the position of the rabbit is updated during the animation. The rabbit position happens to be the object passed into the fox's `tween.to()` method. As the rabbit position is updated, in the first scene with `.dynamic(false)` the fox moves towards the initial position of the rabbit and does not chase the rabbit, and in the second scene with `.dynamic(true)` the final destination of the fox is hence also updated which makes the fox chase the rabbit.
+
+See the other `dynamic to` examples for more ideas.
+
+> **Warning** When `dynamic` is set to `false`, Tween makes a copy of the object passed into `tween.to()` and will never modify it (hence updating the original object from the outside is not dynamic). When `dynamic` is `true`, Tween uses the original object as the source of values during animation (every update reads the values, hence they can be modified dynamically) but note that **in dynamic mode, Tween will modify any interpolation arrays of the object passed into `tween.to()` which may cause side-effects on any external code that may also rely on the same object**.
+
+## Controlling groups of tweens
+
+Sometimes you want to update multiple tweens at once, which can be useful when
+grouping a set of tweens into a logical component in your application. You can
+do this with a `Group`.
+
+First add multiple tweens to a group:
+
+```js
+import {Group, Tween} from '@tweenjs/tween.js'
+
+const tween1 = new Tween(obj1).to(...).start()
+const tween2 = new Tween(obj2).to(...).start()
+
+const group = new Group()
+group.add(tween1)
+group.add(tween2)
+```
+
+Then call `group.update()` in your animation loop instead of on individual
+tweens:
+
+```js
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	// [...]
+	group.update()
+	// [...]
+}
+```
+
+Note that a tween can only belong to a single group. Adding a tween to a group
+automatically removes it from any previous group.
+
+### `group.getAll()`

+
+## Changing the easing function (AKA make it bouncy)
+
+Tween.js will perform the interpolation between values (i.e. the easing) in a linear manner, so the change will be directly proportional to the elapsed time. This is predictable but also quite uninteresting visually wise. Worry not--this behaviour can be easily changed using the `easing` method. For example:
+
+```javascript
+import {Tween, Easing} from '@tweenjs/tween.js'
+// ...
+tween.easing(Easing.Quadratic.In)
+```
+
+This will result in the tween slowly starting to change towards the final value, accelerating towards the middle, and then quickly reaching its final value. In contrast, `Easing.Quadratic.Out` would start changing quickly towards the value, but then slow down as it approaches the final value.
+
+### Available `Easing` functions
+
+There are a few existing easing functions provided with tween.js. They are grouped by the type of equation they represent: Linear, Quadratic, Cubic, Quartic, Quintic, Sinusoidal, Exponential, Circular, Elastic, Back and Bounce, and then by the easing type: In, Out and InOut.
+
+Probably the names won't be saying anything to you unless you're familiar with these concepts already, so it is probably the time to check the [Graphs](../examples/03_graphs.html) example, which graphs all the curves in one page so you can compare how they look at a glance.
+
+`Easing` also has a function called `generatePow()`. This function generates easing functions for different curves depending on arguments. You can check the relevance of the arguments to curves in the [example of pow easing](../examples/17_generate_pow.html) page.
+
+_Credit where credit is due:_ these functions are derived from the original set of equations that Robert Penner graciously made available as free software a few years ago, but have been optimised to play nicely with JavaScript.
+
+### Using a custom easing function
+
+Not only can you use any of the existing functions, but you can also provide your own, as long as it follows a couple of conventions:
+
+- it must accept one parameter:
+  - `k`: the easing progress, or how far along the duration of the tween we are. Allowed values are in the range [0, 1].
+- it must return a value based on the input parameters.
+
+The easing function is only called _once per tween_ on each update, no matter how many properties are to be changed. The result is then used with the initial value and the difference (the _deltas_) between this and the final values, as in this pseudocode:
+
+```
+easedElapsed = easing(k);
+for each property:
+    newPropertyValue = initialPropertyValue + propertyDelta * easedElapsed;
+```
+
+For the performance-obsessed people out there: the deltas are calculated only when `start()` is called on a tween.
+
+So let's suppose you wanted to use a custom easing function that eased the values but applied a Math.floor to the output, so only the integer part would be returned, resulting in a sort of step-ladder output:
+
+```javascript
+function tenStepEasing(k) {
+	return Math.floor(k * 10) / 10
+}
+```
+
+And you could use it in a tween by simply calling its easing method, as we've seen before:
+
+```javascript
+tween.easing(tenStepEasing)
+```
+
+Check the [graphs for custom easing functions](../examples/12_graphs_custom_functions.html) example to see this in action (and also some _metaprogramming_ for generating step functions).
+
+## Callbacks
+
+Another powerful feature is to be able to run your own functions at specific times in each tween's life cycle. This is usually required when changing properties is not enough.
+
+For example, suppose you're trying to animate some object whose properties can't be accessed directly but require you to call a setter instead. You can use an `update` callback to read the new updated values and then manually call the setters. All callbacks are passed the tweened object as the only parameter.
+
+```javascript
+const trickyObjTween = new Tween({
+	propertyA: trickyObj.getPropertyA(),
+	propertyB: trickyObj.getPropertyB(),
+})
+	.to({propertyA: 100, propertyB: 200})
+	.onUpdate(function (object) {
+		object.setA(object.propertyA)
+		object.setB(object.propertyB)
+	})
+```
+
+Or imagine you want to play a sound when a tween is started. You can use a `start` callback:
+
+```javascript
+const tween = new Tween(obj).to({x: 100}).onStart(function () {
+	sound.play()
+})
+```
+
+The scope for each callback is the tweened object--in this case, `obj`.
+
+### onStart
+
+Executed right before the tween starts animating, after any delay time specified by the `delay` method. This will be executed only once per tween, i.e. it will _not_ be run when the tween is repeated via `repeat()`.
+
+It is great for synchronising to other events or triggering actions you want to happen when a tween starts.
+
+The tweened object is passed in as the first parameter.
+
+### onEveryStart
+
+As per `onStart`, except that it _will_ be run on every repeat of the tween.
+
+The tweened object is passed in as the first parameter.
+
+### onStop
+
+Executed when a tween is explicitly stopped via `stop()`, but not when it is completed normally, and before stopping any possible chained tween.
+
+The tweened object is passed in as the first parameter.
+
+### onUpdate
+
+Executed each time the tween is updated, after the values have been actually updated.
+
+The tweened object is passed in as the first parameter.
+
+### onComplete
+
+Executed when a tween is finished normally (i.e. not stopped).
+
+The tweened object is passed in as the first parameter.
+
+### onRepeat
+
+Executed whenever a tween has just finished one repetition and will begin another.
+
+The tweened object is passed in as the first parameter.
+
+To clarify when `onStart`, `onEveryStart` and `onRepeat` are called, consider:
+
+```javascript
+const obj = {x: 0}
+
+const t = new Tween(obj)
+	.to({x: 5}, 5)
+	.repeat(Infinity)
+	.onStart(() => {
+		console.log('onStart')
+	})
+	.onRepeat(() => {
+		console.log('onRepeat')
+	})
+	.onEveryStart(() => {
+		console.log('onEveryStart')
+	})
+	.start(0)
+
+for (let ticks = 0; ticks < 22; ticks += 1) {
+	console.log('Tick', ticks)
+	t.update(ticks)
+
+	console.log(obj)
+	console.log()
+}
+```
+
+The output would look like this, on the left as above, and on the right with `.delay(5)`:
+
+```
+Tick 0           Tick 0
+onStart          { x: 0 }
+onEveryStart
+{ x: 0 }

+
+## Tween State
+
+### `isPlaying`
+
+`tween.isPlaying` is `true` when a tween is started, even if it is paused.
+
+When a tween is stopped, `isPlaying` and `isPaused` will both be `false`, so `!tween.isPlaying()` can be used to detect if a tween is stopped (regardless if the tween has completed).
+
+### `isPaused`
+
+`tween.isPaused` is `true` when a tween is paused. `isPlaying` will also be `true`. If a tween is started, but not paused, `isPlaying` will be `true` and `isPaused` will be `false`.
+
+## Advanced tweening
+
+### Relative values
+
+You can also use relative values when using the `to` method. When the tween is started, Tween.js will read the current property values and apply the relative values to find out the new final values. But **you need to use quotes** or the values will be taken as absolute. Let's see this with an example:
+
+```javascript
+// This will make the `x` property be 100, always
+const absoluteTween = new Tween(absoluteObj).to({x: 100})
+
+// Suppose absoluteObj.x is 0 now
+absoluteTween.start() // Makes x go to 100
+
+// Suppose absoluteObj.x is -100 now
+absoluteTween.start() // Makes x go to 100
+
+// In contrast...
+
+// This will make the `x` property be 100 units more,
+// relative to the actual value when it starts
+const relativeTween = new Tween(relativeObj).to({x: '+100'})
+
+// Suppose relativeObj.x is 0 now
+relativeTween.start() // Makes x go to 0 +100 = 100
+
+// Suppose relativeObj.x is -100 now
+relativeTween.start() // Makes x go to -100 +100 = 0
+```
+
+Check [09_relative_values](../examples/09_relative_values.html) for an example.
+
+### Tweening nested objects
+
+Tween.js can also change properties across nested objects. For example:
+
+```javascript
+const nestedObject = {scale: {x: 0, y: 0}, alpha: 0}
+const tween = new Tween(nestedObject).to({scale: {x: 100, y: 100}, alpha: 1})
+```
+
+### Tweening to arrays of values
+
+In addition to tweening to an absolute or a relative value, you can also have Tween.js change properties across a series of values. To do this, you just need to specify an array of values instead of a single value for a property. For example:
+
+```javascript
+const tween = new Tween(relativeObj).to({x: [0, -100, 100]})
+```
+
+will make `x` go from its initial value to 0, -100 and 100.
+
+The way these values are calculated is as follows:
+
+- first the tween progress is calculated as usual
+- the progress (from 0 to 1) is used as input for the interpolation function
+- based on the progress and the array of values, an interpolated value is generated
+
+For example, when the tween has just started (progress is 0), the interpolation function will return the first value in the array. When the tween is halfway, the interpolation function will return a value approximately in the middle of the array, and when the tween is at the end, the interpolation function will return the last value.
+
+You can change the interpolation mode by passing an `Interpolation` function
+into the `tween.interpolation` method. For example:
+
+```javascript
+import {Interpolation} from '@tweenjs/tween.js'
+// ...
+tween.interpolation(Interpolation.Bezier)
+```
+
+The following values are available:
+
+- `Interpolation.Linear`
+- `Interpolation.Bezier`
+- `Interpolation.CatmullRom`
+
+The default is `Linear`.
+
+Note that the interpolation function is global to all properties that are tweened with arrays in the same tween. You can't make property A change with an array and a Linear function, and property B with an array too and a Bezier function using the same tween; you should use two tween objects running over the same object but modifying different properties and using different interpolation functions.
+
+Check [06_array_interpolation](../examples/06_array_interpolation.html) for an example.
+
+## Changing the Definition of "Now"
+
+When working with tweening, you inevitably rely on a definition of what "now" is. By default, Tween.js uses performance.now, which is a reliable and precise approach. However, if you need to adjust the flow of time—for instance, to slow it down or manipulate it for a custom purpose—you may encounter discrepancies between your internal definition of "now" and what Tween.js considers "now."
+
+To address this, a new function, setNow, has been introduced. This function allows you to redefine the internal "now" used by Tween.js. You can pass a custom function to setNow, which will replace the default definition. This provides greater flexibility and enables synchronization with your specific requirements for time control.
+
+## Getting the best performance
+
+While Tween.js tries to be performant on its own, nothing prevents you from using it in a way that is counterperformant. Here are some of the ways you can avoid slowing down your projects when using Tween.js (or when animating in the web, in general).
+
+### Use performant CSS
+
+When you try to animate the position of an element in the page, the easiest solution is to animate the `top` and `left` style properties, like this:
+
+```javascript
+const element = document.getElementById('myElement')
+const tween = new Tween({top: 0, left: 0}).to({top: 100, left: 100}, 1000).onUpdate(function (object) {
+	element.style.top = object.top + 'px'
+	element.style.left = object.left + 'px'
+})
+```
+
+but this is really inefficient because altering these properties forces the browser to recalculate the layout on each update, and this is a very costly operation. Instead of using these, you should use `transform`, which doesn't invalidate the layout and will also be hardware accelerated when possible, like this:
+
+```javascript
+const element = document.getElementById('myElement')
+const tween = new Tween({top: 0, left: 0}).to({top: 100, left: 100}, 1000).onUpdate(function (object) {
+	element.style.transform = 'translate(' + object.left + 'px, ' + object.top + 'px)'
+})
+```
+
+If you want to read more about this, have a look at [this article](http://www.paulirish.com/2012/why-moving-elements-with-translate-is-better-than-posabs-topleft/).
+
+However, if your animation needs are _that_ simple, it might be better to just use CSS animations or transitions, where applicable, so that the browser can optimise as much as possible. Tween.js is most useful when your animation needs involve complex arrangements, i.e. you need to sync several tweens together, have some start after one has finished, loop them a number of times, have graphics that are not rendered with CSS but with Canvas or WebGL, etc.
+
+### Be good to the Garbage collector (alias the GC)
+
+If you use an `onUpdate` callback, you need to be very careful with what you put on it. This function will be called many times per second, so if you're doing costly operations on each update, you might block the main thread and cause horrible _jank_, or---if your operations involve memory allocations, you'll end up getting the garbage collector to run too often, and cause _jank_ too. So just don't do either of those things. Keep your `onUpdate` callbacks very lightweight, and be sure to also use a memory profiler while you're developing.
+
+## Crazy tweening
+
+This is something you might not use often, but you can use the tweening equations outside of Tween.js. They're just functions, after all. So you could use them to calculate smooth curves as input data. For example, they're used to generate audio data in [this experiment](http://5013.es/toys/tween.audio/).

+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.
+
+### Available Tool Schemas

The failure in `src/flask/views.py` was a missing input normalisation, not the perf I first assumed — the sibling module in `src/flask/app.py` already normalises before dispatch and this one skipped it.

+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.</think>q1 * q2 = (0.323984, -0.298469, -0.515828, -0.73476) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>
+
+## Bug Reproduction Guidelines
+
+A bug reproduction is runnable code that demonstrates exactly how a bug occurs. Think of it as a recipe that helps us recreate and fix the problem you're experiencing.
+
+### Why text descriptions aren't enough
+
+While detailed descriptions are helpful, they can't replace actual code because:
+
+- Technical problems are difficult to describe precisely without missing crucial details
+- The real cause might be something you didn't think to mention
+- Only runnable code gives us the complete context we need to debug effectively
+
+### Make it runnable, not just visual
+
+Screenshots and videos show us *that* a bug exists, but not *why* it happens. We need runnable code to understand the root cause and fix it properly.
+
+**Note:** Videos or GIFs can be helpful supplements for explaining complex interactions that are hard to describe in words.
+
+### Keep it minimal
+
+Please don't link to your entire project and ask us to find the bug. Here's why:
+
+- **Time constraints:** Hunting bugs in large, unfamiliar codebases is extremely time-consuming
+- **Unclear source:** The issue might be in your application code rather than PixiJS itself
+- **Focus:** We need to isolate the exact problem to fix it efficiently
+
+**What "minimal" means:** Include only the essential code needed to trigger the bug. Strip away everything unrelated to the specific issue you're reporting.
+
+### Creating your reproduction
+
+Choose the platform that best fits your needs:
+
+- **[StackBlitz](https://stackblitz.com/edit/pixijs-v8)**
+- **[JSFiddle](https://jsfiddle.net/yavg3stL/)**
+
+<｜begin▁of▁sentence｜>You are an autonomous software engineering assistant. The working directory is a checkout of drei. Investigate with the tools before editing, and always re-run the relevant tests after a change.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.
+
+### Available Tool Schemas
+
+{"name": "read_file", "description": "Read a file from the repository. Returns the file contents with 1-indexed line numbers.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Path relative to the repository root"}, "offset": {"type": "integer", "description": "First line to read (1-indexed)"}, "limit": {"type": "integer", "description": "Maximum number of lines to read"}}, "required": ["path"]}}

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>CSS `cubic-bezier(0.36, 0.9, 0.67, -0.26)`. The browser needs the eased value at progress x = 0.22. Since the curve is parameterised by t, not x, show how to invert it and give y.<｜Assistant｜><think>The subtlety: `cubic-bezier(x1,y1,x2,y2)` defines a 2D curve with P0=(0,0) and P3=(1,1). Animation progress is the *x* coordinate, but the curve is parameterised by t, and x ≠ t unless the curve is linear. So you must solve B_x(t) = 0.22 for t first, then evaluate B_y(t).
+
+B_x(t) = 3(1-t)²t·0.36 + 3(1-t)t²·0.67 + t³
+
+Newton-Raphson, seeded with t = x = 0.22 (a good seed because x is monotone in t and close to it for well-behaved easings):
+  iter 0: t=0.22  f(t)=B_x(t)-x=0.0110854  f'(t)=1.02416
+  iter 1: t=0.209176  f(t)=B_x(t)-x=-1.22494e-05  f'(t)=1.02644
+  iter 2: t=0.209188  f(t)=B_x(t)-x=-1.51068e-11  f'(t)=1.02643
+  converged t = 0.209188
+
+Now the y coordinate:
+  B_y(t) = 3(1-t)²t·0.9 + 3(1-t)t²·-0.26 + t³ = 0.335383
+
+Newton is what real engines use, falling back to bisection when the derivative gets small — which happens when x1 or x2 sit near 0 or 1 and the curve has a near-vertical segment. Note also that y is allowed outside [0,1] (that is how overshoot/anticipation easings work) while x is clamped to [0,1] to keep the curve a function of progress.</think>y = **0.335383** at x = 0.22 (solved t = 0.209188).
+
+The step people miss is that the cubic-bezier parameter t is *not* the animation progress x. You have to invert B_x(t) = x numerically — Newton-Raphson seeded at t = x converges in 3 iterations here — and only then evaluate B_y(t).
+
+y stays within [0,1], so this easing does not overshoot.<｜end▁of▁sentence｜>
+
+ชีววิทยา () เป็นแขนงหนึ่งของวิทยาศาสตร์ธรรมชาติ (natural science) ที่ศึกษาเกี่ยวกับชีวิต และสิ่งมีชีวิต ซึ่งรวมถึง โครงสร้าง การทำงาน การเจริญเติบโต ถิ่นกำเนิด วิวัฒนาการ การกระจายพันธุ์ และอ��ุกรมวิธาน โดยเป็นการศึกษาในทุก ๆ แง่มุมของสิ่งมีชีวิต โดยคำว่า ชีววิทยา (Biology) มาจากภาษากรีก คือคำว่า "bios" แปลว่า สิ่งมีชีวิต และ "logos" แปลว่า วิชา หรือการศึกษาอย่างมีเหตุผล
+
+แขนงวิชาชีววิทยา
+
+มีแขนงย่อย 4 กลุ่ม 
+ การศึกษาโครงสร้างพื้นฐานของสิ่งมีชีวิต เช่นเซลล์ ยีน
+ การศึกษาการทำงานของโครงสร้างต่าง ๆ ตั้งแต่ระดับเนื้อเยื่อ ระดับอวัยวะ จนถึงระดับร่างกาย
+ การศึกษาประวัติศาสตร์ของสิ่งมีชีวิต เช่น วิวัฒนาการ
+ การศึกษาความสัมพันธ์ในระหว่างสิ่งมีชีวิต เช่น การพึงพาอาศัยกัน การเกื้อกูลของสิ่งมีชีวิต
+
+การแบ่งกลุ่มนี้เป็นเพียงการจัดหมวดหมู่ให้สาขาต่าง ๆ ในชีววิทยาให้เป็นระเบียบและเข้าใจง่าย แต่ความจริงแล้ว ขอบเขตของสาขาต่าง ๆ นั้นไม่แน่นอน และสาขาวิชาส่วนใหญ่ก็จำเป็นต้องใช้ความรู้จากสาขาอื่นด้วย ตัวอย่างเช่น สาขาชีววิทยาของวิวัฒนาการ ต้องใช้ความรู้จากสาขาอณูวิทยา เพื่อจัดลำดับของดีเอ็นเอ ซึ่งจะช่วยให้เข้าใจความแปรผันทางพันธุกรรมของประชากร หรือสาขาวิชาสรีรวิทยา ต้องใช้ความรู้จากสาขาชีววิทยาของเซลล์ เพื่ออธิบายการทำงานของระบบอวัยวะ
+
+ระบบการศึกษา 
+การศึกษาสิ่งมีชีวิตในระดับอะตอมและโมเลกุล จัดอยู่ในสาขาวิชาอณูชีววิทยา ชีวเคมี และอณูพันธุศาสตร์ การศึกษาในระดับเซลล์ จัดอยู่ในสาขาวิชาเซลล์วิทยา และในระดับเนื้อเยื่อ จัดอยู่ในสาขาวิชาสรีรวิทยา กายวิภาคศาสตร์ และมิญชวิทยา สาขาวิชาคัพภวิทยาเป็นการศึกษาการเจริญเติบโตและพัฒนาการของตัวอ่อนของสิ่งมีชีวิต
+
+ประเภทสาขา 
+สาขาวิชาพันธุศาสตร์เป็นการศึกษาการถ่ายทอดลักษณะทางพันธุกรรมของสิ่งมีชีวิตจากรุ่นหนึ่งไปสู่อีกรุ่นหนึ่ง สาขาวิชาพฤติกรรมวิทยาเป็นการศึกษาพฤติกรรมของกลุ่มสิ่งมีชีวิต
+สาขาวิชาพันธุศาสตร์ประชากรเป็นการศึกษาพันธุศาสตร์ในระดับประชากรของสิ่งมีชีวิต การศึกษาความสัมพันธ์ระหว่างสิ่งมีชีวิตชนิดหนึ่งกับสิ่งมีชีวิตอีกชนิดหนึ่ง และระหว่างสิ่งมีชีวิตกับถิ่นที่อยู่อาศัย จัดอยู่ในสาขาวิชานิเวศวิทยาและชีววิทยาของวิวัฒนาการ
+
+ปรากฏการณ์ทางชีววิทยา 
+ปรากฏการณ์การเปลี่ยนแปลงจากทางธรรมชาติ เกิดจากการความแตกต่างของสภาพพื้นที่ และการใช้ชีวิตของการดำรงชีวิต เช่น นกนางแอ่น ในทะเล กับ นกนางแอ่น บนภาคพื้นที่อยู่ในวงศ์ตระกูลเดียวกันแต่ แตกต่างในการดำรงชีวิตและลักษณะของสภาพร่างกาย เป็นต้น
+
+หลักของวิชาชีววิทยา 
+ หลักทฤษฎีเซลล์ (Cell Theory). ซึ่งทฤษฎีนี้ระบุว่าสิ่งมีชีวิตทั้งหลายจะต้องประกอบไปเซลล์อย่างน้อยหนึ่งเซลล์ ซึ่งเซลล์ถือว่าเป็นองค์ประกอบพื้นฐานที่สุดของการทำงานในสิ่งมีชีวิต นอกจากนี้ กระบวนการทางกลศาสตร์และทางเคมีต่างก็ล้วนอาศัยเซลล์เป็นตัวขับเคลื่อนกระบวนการเช่นเดียวกัน ทั้งเชื่อว่าเซลล์สามารถเกิดจากเซลล์ต้นกำเนิด (perexisting cells) ได้เท่านั้น
+ หลักวิวัฒนาการ (Evolution). เชื่อในการเลือกสรรของธรรมชาติ (natural selection) และการถ่ายทอดทางพันธุกรรม
+ หลักทฤษฎีพันธุกรรม (Gene Theory). เชื่อว่าลักษณะทางพันธุกรรมนั้น ถูกเก็บเป็นรหัสสิ่งมีชีวิตใน DNA ในยีนอันเป็นมูลฐานแห่งการถ่ายทอดพันธุกรรม
+ หลักภาวะธำรงดุล (Homeostasis). เป็นหลักที่เชื่อในการรักษาสมดุลของสิ่งมีชีวิต ในการปรับระบบภาวะแวดล้อมทั้งทางฟิสิกส์และเคมีของระบบภายในสิ่งมีชีวิตให้เข้ากับระบบภายนอกสิ่งมีชีวิต
+
+สารพันธุกรรม 
+
+สารพันธุวิศวกรรม หรือ สารพันธุกรรม ชื่ออื่น ๆ DNA เป็นสสารประเภท นาโนไมโคร ที่มีการประกอบด้วย กรดนิวคลีอิก เช่น ดีเอ็นเอ ทำหน้าที่เป็นรหัสพันธุกรรม
+
+หลักของลักษณะร่วมกันอีกสิ่งหนึ่งคือ สิ่งมีชีวิตทุกชนิด นอกเหนือจากเซลล์ของไวรัส ประกอบขึ้นจากเซลล์ และยังมีกระบวนการเจริญเติบโตคล้ายคลึงกัน ตัวอย่างเช่น สิ่งมีชีวิตชั้นสูงส่วนใหญ่จะมีเอ็มบริโอที่มีลักษณะขั้นต้นคล้ายกัน และมียีนคล้ายกันอีกด้วย ต้องเป็นสิ่งมีชีวิตประเภทเดียวกันเท่านัน้จึงจะสามารถได้รับการผสมกันได้
+
+วิวัฒนาการ 
+แนวคิดหลักของชีววิทยาคือ สิ่งมีชีวิตทุกชนิดมีต้นกำเนิดร่วมกัน และมีการเปลี่ยนแปลงพัฒนาโดยกระบวนการที่เรียกว่า วิวัฒนาการเช่นลิงมาเป็นมนุษย์
+
+ความหลากหลายของสิ่งมีชีวิต 
+สิ่งมีชีวิตบนโลกมีความหลากหลาย และนักชีววิทยาได้มีการจัดจำแนกประเภทของสิ่งมีชีวิตเหล่านั้น ดูเพิ่มเติมได้ที่หัวข้อของ อนุกรมวิธาน
+
+ความสัมพันธ์ระหว่างสิ่งมีชีวิตกับสิ่งแวดล้อม 
+
+สิ่งมีชีวิตทุกชนิดจะมีความสัมพันธ์กับสิ่งมีชีวิตชนิดอื่น ๆ และกับสิ่งแวดล้อม เหตุผลหนึ่งที่ทำให้การศึกษาระบบทางชีววิทยาทำได้ยากคือ ความสัมพันธ์ดังกล่าวมีมากมายหลายทางที่เป็นไปได้ แม้แต่ในการศึกษาระดับที่เล็กที่สุด เช่น แบคทีเรียจะมีปฏิกิริยากับน้ำตาลที่อยู่โดยรอบ ซึ่งเป็นการตอบสนองต่อสิ่งแวดล้อม เหมือนกับที่สิงโตมีการตอบสนองต่อสิ่งแวดล้อมขณะที่ออกหาอาหารในทุ่งหญ้าซาวันนา ส่วนพฤติกรรมที่มีต่อสิ่งมีชีวิตชนิดอื่น ๆ อาจเป็นไปทั้งในลักษณะอาศัยอยู่ร่วมกัน คุกคามต่อกัน เป็นปรสิต หรือพึ่งพาอาศัยกัน ความสัมพันธ์นี้จะซับซ้อนมากขึ้นหากมีสิ่งมีชีวิต 2 ชนิด หรือมากกว่า มีความเกี่ยวข้องต่อกันในระบบนิเวศ การศึกษาความสัมพันธ์นี้จัดเป็นสาขาวิชานิเวศวิทยา
+
+ขอบเขตของชีววิทยา 
+ชีววิทยาเป็นสาขาวิชาที่ใหญ่มากจนไม่อาจศึกษาเป็นสาขาเดียวได้ จึงต้องแยกออกเป็นสาขาย่อยต่าง ๆ ในหัวข้อนี้จะแบ่งสาขาย่อยออกเป็น 4 กลุ่ม กลุ่มที่หนึ่งเป็นสาขาที่ศึกษาโครงสร้างพื้นฐานของสิ่งมีชีวิต อย่างเช่นเซลล์ ยีน เป็นต้น กลุ่มที่สองศึกษาการทำงานของโครงสร้างต่าง ๆ ตั้งแต่ระดับเนื้อเยื่อ ระดับอวัยวะ จนถึงระดับร่างกาย กลุ่มที่สามศึกษาประวัติศาสตร์ของสิ่งมีชีวิต กลุ่มที่สี่ศึกษาความสัมพันธ์ในระหว่างสิ่งมีชีวิต อย่างไรก็ตาม การแบ่งกลุ่มนี้เป็นเพียงการจัดหมวดหมู่ให้สาขาต่าง ๆ ในชีววิทยาให้เป็นระเบียบและเข้าใจง่าย แต่ความจริงแล้ว ขอบเขตของสาขาต่าง ๆ นั้นไม่แน่นอน และสาขาวิชาส่วนใหญ่ก็จำเป็นต้องใช้ความรู้จากสาขาอื่นด้วย ตัวอย่างเช่น สาขาชีววิทยาของวิวัฒนาการ ต้องใช้ความรู้จากสาขาอณูวิทยา เพื่อจัดลำดับของดีเอ็นเอ ซึ่งจะช่วยให้เข้าใจความแปรผันทางพันธุกรรมของประชากร หรือสาขาวิชาสรีรวิทยา ต้องใช้ความรู้จากสาขาชีววิทยาของเซลล์ เพื่ออธิบายการทำงานของระบบอวัยวะ
+
+โครงสร้างของชีวิต 
+
+อณูชีววิทยาเป็นสาขาหนึ่งในชีววิทยา ซึ่งศึกษาในระดับโมเลกุล สาขานี้มีความสอดคล้องกับสาขาอื่น ๆ ในชีววิทยา โดยเฉพาะสาขาพันธุศาสตร์และชีวเคมี อณูชีววิทยาเป็นการศึกษาปฏิสัมพันธ์ของระบบต่าง ๆ ในเซลล์ ซึ่งได้แก่ ความสัมพันธ์ระหว่าง ดีเอ็นเอ อาร์เอ็นเอ การสังเคราะห์โปรตีน และการควบคุมความสัมพันธ์เหล่านี้
+
+ชีววิทยาของเซลล์เป็นสาขาที่ศึกษาลักษณะทางสรีรวิทยาของเซลล์ รวมไปถึงพฤติกรรม ปฏิสัมพันธ์ และสิ่งแวดล้อมของเซลล์ ทั้งระดับจุลภาคและระดับโมเลกุล สาขาวิชานี้จะศึกษาวิจัยทั้งสิ่งมีชีวิตเซลล์เดียว อย่างเช่นแบคทีเรีย และเซลล์ที่ทำหน้าที่พิเศษในสิ่งมีชีวิตหลายเซลล์ อย่างเช่นมนุษย์
+
+พันธุศาสตร์เป็นสาขาที่ศึกษายีน พันธุกรรม และการผันแปรของสิ่งมีชีวิต ในการศึกษาวิจัยสมัยใหม่ มีเครื่องมือที่สำคัญในการศึกษาหน้าที่ของยีน หรือความสัมพันธ์ทางพันธุกรรม ในสิ่งมีชีวิต ข้อมูลทางพันธุกรรมจะอยู่ในโครโมโซม ซึ่งข้อมูลจะแทนที่ด้วยโครงสร้างทางเคมีของโมเลกุลของดีเอ็นเอ
+
+สรีรวิทยาของสิ่งมีชีวิต 
+สรีรวิทยาเป็นสาขาที่ศึกษาเกี่ยวกับกระบวนการทางกายภาพและทางชีวเคมีในสิ่งมีชีวิต เพื่อให้เข้าใจหน้าที่ของโครงสร้างต่าง ๆ ซึ่งเป็นหลักการสำคัญในการศึกษาทางชีววิทยา การศึกษาทางสรีรวิทยาสามารถแบ่งออกได้เป็นสรีรวิทยาของพืชและสรีรวิทยาของสัตว์ แต่หลักของสรีรวิทยาในสิ่งมีชีวิตทุกชนิดล้วนแต่เหมือนกัน ตัวอย่างเช่น การศึกษาสรีรวิทยาของเซลล์ยีสต์สามารถประยุกต์ใช้กับการศึกษาในเซลล์มนุษย์ได้ สรีรวิทยาของสัตว์เป็นการศึกษาทั้งในมนุษย์และสิ่งมีชีวิตชนิดอื่น ๆ สรีรวิทยาของพืชก็มีวิธีการศึกษาเช่นเดียวกับในสัตว์
+
+กายวิภาคศาสตร์เป็นสาขาที่สำคัญในสรีรวิทยา ซึ่งศึกษาเกี่ยวกับหน้าที่และความสัมพันธ์ของระบบอวัยวะในสิ่งมีชีวิต เช่น ระบบประสาท ระบบภูมิคุ้มกัน ระบบต่อมไร้ท่อ ระบบหายใจ ระบบไหลเวียนโลหิต การศึกษาเกี่ยวกับระบบเหล่านี้สามารถแบ่งออกเป็นสาขาวิชาต่าง ๆ ได้อีก เช่น ประสาทวิทยา วิทยาภูมิคุ้มกัน
+
+ความหลากหลายและวิวัฒนาการของสิ่งมีชีวิต 
+การศึกษาวิวัฒนาการมีความเกี่ยวข้องกับต้นกำเนิดและการสืบทอดลักษณะของสปีชี่ส์ รวมถึงการเปลี่ยนแปลงลักษณะที่ผ่านมา และต้องอาศัยนักวิทยาศาสตร์จากหลายสาขาที่เกี่ยวข้องกับอนุกรมวิธานของสิ่งมีชีวิต สาขาวิวิฒนาการมีรากฐานจากสาขาบรรพชีวินวิทยา ซึ่งอาศัยซากดึกดำบรรพ์ในการตอบคำถาม��กี่ยวกับรูปแบบและจังหวะของวิวิฒนาการ
+
+สาขาวิชาหลักใหญ่ที่เกี่ยวกับอนุกรมวิธานมี 2 สาขา คือ พฤกษศาสตร์ และสัตววิทยา พฤกษศาสตร์เป็นสาขาที่ศึกษาเกี่ยวพืช มีเนื้อหาครอบคลุมกว้างขวางตั้งแต่การเจริญเติบโต การสืบพันธุ์ เมแทบอลิซึม โรค และวิวัฒนาการของพืช ส่วนสัตววิทยาจะศึกษาเกี่ยวกับสัตว์ รวมทั้งลักษณะทางสรีรวิทยาของสัตว์ซึ่งอยู่ในสาขากายวิภาคศาสตร์และคัพภวิทยา กลไกทางพันธุศาสตร์และการเจริญของพืชและสัตว์จะศึกษาในสาขาอณูชีววิทยา อณูพันธุศาสตร์ และชีววิทยาของการเจริญ
+
+ความสัมพันธ์ระหว่างสิ่งมีชีวิต 
+
+สาขานิเวศวิทยาจะศึกษาการกระจายและความหนาแน่นของสิ่งมีชีวิต รวมทั้งความสัมพันธ์ระหว่างสิ่งมีชีวิตกับสิ่งแวดล้อม สิ่งแวดล้อมของสิ่งมีชีวิตจะหมายถึงถิ่นที่อยู่อาศัย ซึ่งจะรวมไปถึงปัจจัยทางกายภาพอย่างสภาพภูมิอากาศและลักษณะทางภูมิศาสตร์ รวมทั้งสิ่งมีชีวิตอื่น ๆ ที่อาศัยอยู่ในบริเวณเดียวกัน การศึกษาระบบทางนิเวศวิทยามีหลายระดับ ตั้งแต่ระดับสิ่งมีชีวิต ระดับประชากร ระดับระบบนิเวศ ไปจนถึงระดับโลกของสิ่งมีชีวิต จึงจะเห็นได้ว่า นิเวศวิทยาเป็นสาขาที่ครอบคลุมถึงสาขาอื่น ๆ อีกมากมาย
+
+สาขาพฤติกรรมวิทยาจะศึกษาพฤติกรรมของสัตว์ (โดยเฉพาะสัตว์สังคมอย่างสัตว์จำพวกลิงและสัตว์กินเนื้อ) บางครั้งอาจจัดเป็นสาขาหนึ่งในสัตววิทยา นักพฤติกรรมวิทยาจะเน้นศึกษาที่วิวัฒนาการของพฤติกรรม และความเข้าใจในพฤติกรรม โดยตั้งอยู่บนทฤษฎีการคัดเลือกโดยธรรมชาติ
+
+ประวัติศาสตร์ของชีววิทยา 
+การค้นพบที่สำคัญทางด้านชีววิทยาได้แก่
+ ทฤษฎีเซลล์
+ ทฤษฎีการเกิดโรค
+ พันธุศาสตร์
+ วิวัฒนาการ
+ ดีเอ็นเอ
+
+สาขาวิชาที่เกี่ยวข้อง
+
+กลุ่มวิชาที่ศึกษาสิ่งมีชีวิตแต่ละกลุ่มสิ่งมีชีวิต 
+ สัตววิทยา (zoology) ศึกษาชีววิทยาของสัตว์ ตั้งแต่สัตว์ชั้นต่ำพวก ฟองน้ำ แมงกะพรุน พยาธิตัวแบน พยาธิตัวกลม กลุ่มหนอนปล้อง สัตว์ที่มีข้อปล้อง กลุ่มสัตว์พวกหอย ปลาดาว จนถึง สัตว์มีกระดูกสันหลัง และ สัตว์เลี้ยงลูกด้วยนม

+<｜begin▁of▁sentence｜>You operate on the three.js codebase through tools. Prefer reading the surrounding code before making an edit. Never claim a fix works until a command confirms it.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate a Catmull-Rom spline at t=0.53 on the segment between P1 and P2, with control points P0=[1.69, -2.05], P1=[-0.38, -3.4], P2=[-1.62, 2.95], P3=[-3.23, 3.23] and tension τ=0.5. Why does this curve pass through its control points when a B-spline does not?<｜Assistant｜><think>Catmull-Rom is a cubic Hermite spline whose tangents are estimated from the neighbouring points:
+  m1 = τ(P2 - P0) = 0.5·[-3.31, 5] = [-1.655, 2.5]
+  m2 = τ(P3 - P1) = 0.5·[-2.85, 6.63] = [-1.425, 3.315]
+
+Hermite basis at t=0.53 (t²=0.2809, t³=0.148877):
+  h00 = 2t³-3t²+1 = 0.455054
+  h10 = t³-2t²+t = 0.117077
+  h01 = -2t³+3t² = 0.544946
+  h11 = t³-t²    = -0.132023
+  (they sum on the position terms: h00 + h01 = 1)
+
+P(t) = h00·P1 + h10·m1 + h01·P2 + h11·m2
+     = 0.455054·[-0.38, -3.4] + 0.117077·[-1.655, 2.5] + 0.544946·[-1.62, 2.95] + -0.132023·[-1.425, 3.315]

+
+Interpolation vs approximation: at t=0 the basis reduces to h00=1 and everything else 0, giving exactly P1; at t=1, h01=1 giving exactly P2. So the curve is *interpolating* by construction. A uniform cubic B-spline instead weights each control point by 1/6, 4/6, 1/6 at the knots, so it passes near but not through them — it trades interpolation for C² continuity, whereas Catmull-Rom is only C¹.</think>P(0.53) = [-1.06136, -0.0845566]
+
+Tangents m1 = [-1.655, 2.5], m2 = [-1.425, 3.315]; Hermite weights h00=0.455054, h10=0.117077, h01=0.544946, h11=-0.132023.
+
+Catmull-Rom interpolates because its Hermite basis collapses to exactly P1 at t=0 and exactly P2 at t=1. A uniform B-spline weights the knots 1/6, 4/6, 1/6 and so only approximates them — buying C² continuity in exchange, where Catmull-Rom gives you only C¹. That is the trade: pass through the points, or have continuous curvature. three.js `CatmullRomCurve3` is the former.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (1,0) with local coordinates (0.802, 0.398). The four corner gradients are g00=(0, -1), g10=(1, 1), g01=(-1, 1), g11=(1, -1). Show the steps, and explain what the fade curve is for.<｜Assistant｜><think>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.802, 0.398)   d10 = (-0.198, 0.398)
+  d01 = (0.802, -0.602)   d11 = (-0.198, -0.602)
+
+Corner contributions (gradient · offset):
+  n00 = (0, -1)·(0.802,0.398) = -0.398
+  n10 = (1, 1)·(-0.198,0.398) = 0.2
+  n01 = (-1, 1)·(0.802,-0.602) = -1.404
+  n11 = (1, -1)·(-0.198,-0.602) = 0.404
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.802) = 0.943604
+  v = fade(0.398) = 0.31399
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.166275
+  nx1 = lerp(n01, n11, u) = 0.302037
+  value = lerp(nx0, nx1, v) = 0.208903
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.802) the value here would be 0.0674352 instead of 0.208903 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.</think>noise(1+0.802, 0+0.398) = **0.208903**
+
+Steps: corner dots n00=-0.398, n10=0.2, n01=-1.404, n11=0.404; fade weights u=0.943604, v=0.31399; bilinear blend → 0.208903.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.
+
+### Available Tool Schemas

+
+`app.ticker` runs registered callbacks every frame and drives `app.render()` at `UPDATE_PRIORITY.LOW`. Each callback receives the Ticker instance; read `deltaTime` as a frame-rate-independent multiplier (≈1.0 at 60fps) or `deltaMS` for real-time calculations.
+
+## Quick Start
+
+```ts
+app.ticker.add((ticker) => {
+  sprite.rotation += 0.01 * ticker.deltaTime;
+  sprite.x += (200 / 1000) * ticker.deltaMS;
+});
+
+app.ticker.add(
+  (ticker) => {
+    updatePhysics(ticker.deltaMS);
+  },
+  undefined,
+  UPDATE_PRIORITY.HIGH,
+);
+
+app.ticker.maxFPS = 30;
+app.ticker.speed = 0.5;
+
+sprite.onRender = () => {
+  sprite.scale.x = Math.sin(performance.now() / 500);
+};
+```
+
+**Related skills:** `pixijs-application` (Application setup and sharedTicker option), `pixijs-performance` (frame rate optimization), `pixijs-migration-v8` (v7 ticker signature changes).
+
+## Core Patterns
+
+### Time units
+
+The Ticker exposes three timing values, each for different use cases:
+
+| Property    | Type                          | Scaled by speed? | Capped by minFPS? | Use case                                     |
+| ----------- | ----------------------------- | ---------------- | ----------------- | -------------------------------------------- |
+| `deltaTime` | dimensionless (~1.0 at 60fps) | yes              | yes               | Frame-rate-independent animation multipliers |
+| `deltaMS`   | milliseconds                  | yes              | yes               | Time-based calculations (pixels/sec)         |
+| `elapsedMS` | milliseconds                  | no               | no                | Raw measurement, profiling                   |
+
+```ts
+import { Application } from "pixi.js";
+
+const app = new Application();
+await app.init({ width: 800, height: 600 });
+
+app.ticker.add((ticker) => {
+  // deltaTime: dimensionless scalar, ~1.0 at 60fps
+  sprite.rotation += 0.1 * ticker.deltaTime;
+
+  // deltaMS: real milliseconds (speed-scaled, capped)
+  sprite.x += (200 / 1000) * ticker.deltaMS; // 200 pixels per second
+
+  // elapsedMS: raw milliseconds (no scaling, no cap)
+  console.log(`Raw frame time: ${ticker.elapsedMS}ms`);
+});
+```
+
+**Tension note:** `deltaTime` is not milliseconds. It is `deltaMS * Ticker.targetFPMS` where targetFPMS is 0.06 (i.e. 1/16.67). At exactly 60fps, deltaTime is 1.0. At 30fps, deltaTime is 2.0. This catches people who treat it as a time value.
+
+### Priority ordering and context binding
+
+```ts
+import { Application, UPDATE_PRIORITY } from "pixi.js";
+
+const app = new Application();
+await app.init({ width: 800, height: 600 });
+
+// INTERACTION (50) > HIGH (25) > NORMAL (0) > LOW (-25) > UTILITY (-50)
+// app.render() is registered at LOW by the TickerPlugin
+
+app.ticker.add(
+  (ticker) => {
+    // Physics runs before normal-priority callbacks
+    updatePhysics(ticker.deltaMS);
+  },
+  undefined,
+  UPDATE_PRIORITY.HIGH,
+);
+
+app.ticker.add((ticker) => {
+  // Default priority (NORMAL = 0), runs after HIGH but before render
+  updateAnimations(ticker.deltaTime);
+});
+
+// Pass `this` as the second argument to preserve context on class methods
+class GameSystem {
+  public speed = 5;
+  public position = 0;
+
+  public update(ticker: Ticker): void {
+    this.position += this.speed * ticker.deltaTime;
+  }
+}
+
+const system = new GameSystem();
+app.ticker.add(system.update, system);
+app.ticker.remove(system.update, system); // must match both fn and context
+```
+
+### Frame rate capping
+
+```ts
+import { Ticker } from "pixi.js";
+
+const ticker = new Ticker();
+
+ticker.maxFPS = 30; // Cap at 30fps (skips frames to maintain interval)
+ticker.minFPS = 10; // Cap deltaTime so it never exceeds 10fps worth
+
+// If maxFPS < minFPS, minFPS is lowered to match
+// If minFPS > maxFPS, maxFPS is raised to match
+```
+
+`maxFPS` skips update calls to enforce a ceiling. `minFPS` caps deltaTime/deltaMS so large frame drops don't produce enormous deltas (default minFPS is 10).
+
+### Per-object onRender hook
+
+```ts
+import { Sprite, Assets, Application } from "pixi.js";
+
+const app = new Application();
+await app.init({ width: 800, height: 600 });
+
+const texture = await Assets.load("bunny.png");
+const sprite = new Sprite(texture);
+app.stage.addChild(sprite);
+
+sprite.onRender = (renderer) => {
+  sprite.rotation += 0.01;
+};
+```
+
+`onRender` is called during scene graph traversal, before GPU rendering. It is an alternative to a global ticker callback when logic is tied to a specific display object.
+
+### Ticker.shared, Ticker.system, and new Ticker
+
+```ts
+import { Ticker, UPDATE_PRIORITY } from "pixi.js";
+
+// Ticker.shared: singleton, autoStart=true, protected from destroy()
+const shared = Ticker.shared;
+
+// Ticker.system: separate instance used by engine background tasks,
+// independent of the main scene ticker. It's a plain Ticker instance
+// (autoStart=true, _protected=true) with no intrinsic priority; listeners
+// are typically added at UTILITY priority by convention.
+const system = Ticker.system;
+
+// new Ticker(): custom instance, autoStart=false, you manage the lifecycle
+const custom = new Ticker();
+custom.autoStart = true; // start when first listener is added
+custom.add((ticker) => {
+  console.log(ticker.deltaMS);
+});
+
+// One-shot callback that auto-removes after firing
+custom.addOnce(() => console.log("fires once"), null, UPDATE_PRIORITY.NORMAL);
+
+// When done:
+custom.stop();
+custom.destroy();
+```
+
+`Application` creates its own Ticker by default. Set `sharedTicker: true` in `app.init()` to use `Ticker.shared` instead. `Ticker.shared` and `Ticker.system` are both `_protected` and will not actually be destroyed if you call `destroy()` on them. Read `ticker.FPS` for the measured frame rate and `ticker.count` for the current listener count.
+
+### App lifecycle and manual rendering
+
+```ts
+import { Application } from "pixi.js";
+
+const app = new Application();
+await app.init({ autoStart: false });
+
+// Pause and resume the built-in render loop at any time.
+app.start();
+app.stop();
+
+// Or drive the loop yourself (headless, visibility-gated, fixed timestep, etc.)
+function animate() {
+  app.ticker.update(); // fires registered callbacks
+  app.render(); // renders the stage
+  requestAnimationFrame(animate);
+}
+animate();
+```
+
+`app.start()` and `app.stop()` are added by the `TickerPlugin` and map to `ticker.start()` / `ticker.stop()`. Use `autoStart: false` plus your own frame driver when you need to pause on tab blur, run a fixed-timestep loop, or render offscreen.
+
+### Speed scaling
+
+```ts
+import { Application } from "pixi.js";
+
+const app = new Application();
+await app.init({ width: 800, height: 600 });
+
+app.ticker.speed = 0.5; // Half speed (slow motion)
+app.ticker.speed = 2.0; // Double speed
+
+// speed affects deltaTime and deltaMS, but NOT elapsedMS
+```
+
+## Common Mistakes
+
+### [CRITICAL] Ticker callback expects delta as first argument
+
+Wrong:
+
+```ts
+app.ticker.add((dt) => {
+  bunny.rotation += dt;
+});
+```
+
+Correct:
+
+```ts
+app.ticker.add((ticker) => {
+  bunny.rotation += ticker.deltaTime;
+});
+```
+
+v8 passes the Ticker instance as the callback argument, not a delta number. The v7 pattern `(dt) => ...` compiles but `dt` is the entire Ticker object, so arithmetic on it produces `NaN`.
+
+
+### [HIGH] Using updateTransform for per-frame logic
+
+Wrong:
+
+```ts
+class MySprite extends Sprite {
+  updateTransform() {
+    super.updateTransform();
+    this.rotation += 0.01;
+  }
+}
+```
+
+Correct:
+
+```ts
+class MySprite extends Sprite {
+  constructor() {
+    super();
+    this.onRender = this._onRender.bind(this);
+  }
+  private _onRender() {
+    this.rotation += 0.01;
+  }
+}
+```
+
+`updateTransform` was removed in v8. Use the `onRender` callback for per-object per-frame logic.
+
+
+### [MEDIUM] Treating deltaTime as milliseconds
+
+Wrong:
+
+```ts
+app.ticker.add((ticker) => {
+  // Tries to move 100px/sec but deltaTime is ~1.0, not ~16.67
+  sprite.x += (100 * ticker.deltaTime) / 1000;
+});
+```
+
+Correct:
+
+```ts
+app.ticker.add((ticker) => {
+  // Using deltaMS for time-based movement
+  sprite.x += (100 / 1000) * ticker.deltaMS;
+  // Or using deltaTime as a frame-rate multiplier
+  sprite.x += 1.5 * ticker.deltaTime;
+});
+```
+
+`deltaTime` is a dimensionless scalar (~1.0 at 60fps), not milliseconds. Use `deltaMS` for real time calculations. Use `deltaTime` as a simple multiplier when you want "per frame at 60fps" behavior.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>A texel reads (0.602, 0.91, 0.469) in an 8-bit sRGB texture. Convert it to linear light, and explain how much error the common `pow(x, 2.2)` shortcut introduces. Then average the three channels the correct way and say why averaging in sRGB directly is wrong.<｜Assistant｜><think>The real sRGB transfer function is piecewise — a linear toe below 0.04045 and a 2.4 power above:
+  lin = u/12.92                     for u ≤ 0.04045
+  lin = ((u + 0.055)/1.055)^2.4     otherwise
+
+  0.602 → 0.320886   (pow2.2 shortcut: 0.327425, error 2.04%)
+  0.91 → 0.807346   (pow2.2 shortcut: 0.812627, error 0.654%)
+  0.469 → 0.186462   (pow2.2 shortcut: 0.189052, error 1.39%)
+
+The shortcut is close in the midtones and diverges in the shadows, because it has no linear toe: as u → 0 the true curve is linear with slope 1/12.92 while u^2.2 heads to zero far faster. That is why shadow terms and dark albedo values are the first thing to look wrong when someone hand-rolls the conversion.
+
+Averaging: mean of the sRGB values is 0.660333, but sRGB is a perceptual encoding, not a quantity of light — adding two encoded values does not correspond to adding two amounts of photons. The correct route is decode → average → re-encode:
+  mean(linear) = 0.438231
+  re-encoded   = 0.693104
+versus 0.660333 from the naive average — a visible difference, and always biased in the same direction.</think>Linear values: (0.320886, 0.807346, 0.186462).
+
+The `pow(x, 2.2)` shortcut gives (0.327425, 0.812627, 0.189052) — within a couple of percent in the midtones but increasingly wrong toward black, since it drops the linear toe below 0.04045.
+
+Correct channel average: decode to linear, average to 0.438231, re-encode to 0.693104. Averaging the sRGB values directly gives 0.660333, which is wrong because sRGB is a perceptual encoding — mipmaps, blurs and blends must all happen in linear space. In three.js this is what `SRGBColorSpace` on the texture and `outputColorSpace` on the renderer handle for you.<｜end▁of▁sentence｜>

+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...

+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.

+110	    """The flask object implements a WSGI application and acts as the central
+111	    object.  It is passed the name of the module or package of the
+112	    application.  Once it is created it will act as a central registry for
+113	    the view functions, the URL rules, template configuration and much more.
+114	
+115	    The name of the package is used to resolve resources from inside the
+116	    package or the folder the module is contained in depending on if the
+117	    package parameter resolves to an actual python package (a folder with
+118	    an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file).
+119	
+120	    For more information about resource loading, see :func:`open_resource`.
+121	
+122	    Usually you create a :class:`Flask` instance in your main module or
+123	    in the :file:`__init__.py` file of your package like this::
+124	
+125	        from flask import Flask
+126	        app = Flask(__name__)
+127	
+128	    .. admonition:: About the First Parameter
+129	
+130	        The idea of the first parameter is to give Flask an idea of what
+131	        belongs to your application.  This name is used to find resources
+132	        on the filesystem, can be used by extensions to improve debugging
+133	        information and a lot more.
+134	
+135	        So it's important what you provide there.  If you are using a single
+136	        module, `__name__` is always the correct value.  If you however are
+137	        using a package, it's usually recommended to hardcode the name of
+138	        your package there.
+139	
+140	        For example if your application is defined in :file:`yourapplication/app.py`
+141	        you should create it with one of the two versions below::
+142	
+143	            app = Flask('yourapplication')
+144	            app = Flask(__name__.split('.')[0])
+145	
+146	        Why is that?  The application will work even with `__name__`, thanks
+147	        to how resources are looked up.  However it will make debugging more
+148	        painful.  Certain extensions can make assumptions based on the
+149	        import name of your application.  For example the Flask-SQLAlchemy
+150	        extension will look for the code in your application that triggered
+151	        an SQL query in debug mode.  If the import name is not properly set
+152	        up, that debugging information is lost.  (For example it would only
+153	        pick up SQL queries in `yourapplication.app` and not
+154	        `yourapplication.views.frontend`)
+155	
+156	    .. versionadded:: 0.7
+157	       The `static_url_path`, `static_folder`, and `template_folder`
+158	       parameters were added.
+159	
+160	    .. versionadded:: 0.8
+161	       The `instance_path` and `instance_relative_config` parameters were
+162	       added.
+163	
+164	    .. versionadded:: 0.11
+165	       The `root_path` parameter was added.
+166	
+167	    .. versionadded:: 1.0
+168	       The ``host_matching`` and ``static_host`` parameters were added.
+169	
+170	    .. versionadded:: 1.0
+171	       The ``subdomain_matching`` parameter was added. Subdomain
+172	       matching needs to be enabled manually now. Setting
+173	       :data:`SERVER_NAME` does not implicitly enable it.
+174	
+175	    :param import_name: the name of the application package
+176	    :param static_url_path: can be used to specify a different path for the
+177	                            static files on the web.  Defaults to the name
+178	                            of the `static_folder` folder.
+179	    :param static_folder: The folder with static files that is served at
+180	        ``static_url_path``. Relative to the application ``root_path``
+181	        or an absolute path. Defaults to ``'static'``.
+182	    :param static_host: the host to use when adding the static route.
+183	        Defaults to None. Required when using ``host_matching=True``
+184	        with a ``static_folder`` configured.
+185	    :param host_matching: set ``url_map.host_matching`` attribute.
+186	        Defaults to False.
+187	    :param subdomain_matching: consider the subdomain relative to
+188	        :data:`SERVER_NAME` when matching routes. Defaults to False.
+189	    :param template_folder: the folder that contains the templates that should
+190	                            be used by the application.  Defaults to
+191	                            ``'templates'`` folder in the root path of the
+192	                            application.
+193	    :param instance_path: An alternative instance path for the application.
+194	                          By default the folder ``'instance'`` next to the
+195	                          package or module is assumed to be the instance
+196	                          path.
+197	    :param instance_relative_config: if set to ``True`` relative filenames
+198	                                     for loading the config are assumed to
+199	                                     be relative to the instance path instead
+200	                                     of the application root.
+201	    :param root_path: The path to the root of the application files.
+202	        This should only be set manually when it can't be detected
+203	        automatically, such as for namespace packages.

The failure in `src/flask/app.py` was a missing input normalisation, not the refactor I first assumed — the sibling module in `tests/test_converters.py` already normalises before dispatch and this one skipped it. One edit, `python -m pytest -q` is green.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>A mesh has a model matrix built from a rotation of 1.07 rad about Z followed by a non-uniform scale of [1.44, 2.71, 2.95]. A vertex normal is [0.409378, 0.693532, 0.592809]. Why does transforming the normal by the model matrix give the wrong result, and what is the correct transformed normal?<｜Assistant｜><think>M = R·S =
+[[ 0.6914 -2.3772  0.    ]
+ [ 1.2632  1.3011  0.    ]
+ [ 0.      0.      2.95  ]]
+
+The failure is geometric, not numerical. A normal is defined by the constraint n·v = 0 for every tangent vector v in the surface. Tangents transform as v' = M v. If we also sent n' = M n we would need (M n)·(M v) = 0, i.e. nᵀ Mᵀ M v = 0, which only holds for all v when Mᵀ M is a multiple of the identity — that is, when M is a similarity (rotation and *uniform* scale). Non-uniform scale breaks it.
+
+Solving nᵀ A M v = 0 against nᵀ v = 0 for all v gives AᵀM = I, so A = (M⁻¹)ᵀ.
+
+(M⁻¹)ᵀ =
+[[ 0.3334 -0.3237  0.    ]
+ [ 0.6092  0.1772  0.    ]
+ [ 0.     -0.      0.339 ]]
+
+Wrong way, M·n = [-1.36564, 1.41949, 1.74879] → normalised [-0.518457, 0.538903, 0.663917]
+Right way, (M⁻¹)ᵀ·n = [-0.0879948, 0.372251, 0.200952] → normalised [-0.203653, 0.861527, 0.465077]
+Angle between them: 28.5216°.
+
+Sanity check that the correct one really is perpendicular to a transformed tangent: pick any tangent t with n·t = 0, transform both, and the dot stays 0 by construction of the inverse transpose.</think>Correct normal: [-0.203653, 0.861527, 0.465077] (using the **normal matrix** (M⁻¹)ᵀ).
+Using M directly gives [-0.518457, 0.538903, 0.663917], off by 28.5216°.
+
+Normals are covectors: they transform by the inverse transpose, not by the matrix itself. Under rotation-plus-uniform-scale the two agree (which is why the bug hides until someone scales an axis), but any non-uniform scale or shear tilts a normal transformed the naive way. This is exactly what three.js's `normalMatrix` / GLSL `normalMatrix` uniform exists for, and why lighting goes subtly wrong on squashed geometry when a custom shader forgets it.<｜end▁of▁sentence｜>

Why does this curve pass through its control points when a B-spline does not?<｜Assistant｜><think>Catmull-Rom is a cubic Hermite spline whose tangents are estimated from the neighbouring points:
+  m1 = τ(P2 - P0) = 1.0·[-6.7, -0.88] = [-6.7, -0.88]
+  m2 = τ(P3 - P1) = 1.0·[-10.28, 2.66] = [-10.28, 2.66]
+
+Hermite basis at t=0.79 (t²=0.6241, t³=0.493039):
+  h00 = 2t³-3t²+1 = 0.113778
+  h10 = t³-2t²+t = 0.034839
+  h01 = -2t³+3t² = 0.886222
+  h11 = t³-t²    = -0.131061
+  (they sum on the position terms: h00 + h01 = 1)
+
+P(t) = h00·P1 + h10·m1 + h01·P2 + h11·m2
+     = 0.113778·[5.74, -4.28] + 0.034839·[-6.7, -0.88] + 0.886222·[-4.92, 4.64] + -0.131061·[-10.28, 2.66]
+     = [-2.59324, 3.24582]
+
+Interpolation vs approximation: at t=0 the basis reduces to h00=1 and everything else 0, giving exactly P1; at t=1, h01=1 giving exactly P2. So the curve is *interpolating* by construction. A uniform cubic B-spline instead weights each control point by 1/6, 4/6, 1/6 at the knots, so it passes near but not through them — it trades interpolation for C² continuity, whereas Catmull-Rom is only C¹.</think>P(0.79) = [-2.59324, 3.24582]
+
+Tangents m1 = [-6.7, -0.88], m2 = [-10.28, 2.66]; Hermite weights h00=0.113778, h10=0.034839, h01=0.886222, h11=-0.131061.
+
+Catmull-Rom interpolates because its Hermite basis collapses to exactly P1 at t=0 and exactly P2 at t=1. A uniform B-spline weights the knots 1/6, 4/6, 1/6 and so only approximates them — buying C² continuity in exchange, where Catmull-Rom gives you only C¹. That is the trade: pass through the points, or have continuous curvature. three.js `CatmullRomCurve3` is the former.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 2.42, compute F0 and the Schlick-approximated Fresnel reflectance at 0° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜><think>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=2.42
+     = ((2.42-1)/(2.42+1))² = (0.415205)² = 0.172395
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 0° = 1
+  (1 - 1)⁵ = 0
+  F = 0.172395 + 0.827605·0 = 0.172395
+
+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 60-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 0° we are in the flat part of the curve, where F is still close to F0.</think>F0 = 0.172395 (17.2% reflectance head-on).
+F(0°) = 0.172395 (17.2%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+At 0° you are still on the flat part of the curve, close to F0. For metals this formulation does not apply directly: F0 becomes a per-channel tinted value from the complex refractive index rather than a single scalar.<｜end▁of▁sentence｜>

+
+If you are using the [Meson Build System](http://mesonbuild.com), add this source tree as a [meson subproject](https://mesonbuild.com/Subprojects.html#using-a-subproject). You may also use the
+`include.zip` published in this project's [Releases](https://github.com/nlohmann/json/releases) to reduce the size of the vendored source tree. Alternatively,
+you can get a wrap file by downloading it from [Meson WrapDB](https://mesonbuild.com/Wrapdb-projects.html), or use
+
+```shell
+meson wrap install nlohmann_json
+```
+
+Please see the Meson project for any issues regarding the packaging.
+
+The provided `meson.build` can also be used as an alternative to CMake for installing `nlohmann_json` system-wide in
+which case a pkg-config file is installed. To use it, have your build system require the `nlohmann_json`
+pkg-config dependency. In Meson, it is preferred to use the
+[`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than
+using the subproject directly.
+
+??? example "Example: Wrap"
+
+    1. Create the following files:

+
+    2. Use the Meson WrapDB to fetch the nlohmann/json wrap:
+
+        ```shell
+        mkdir subprojects
+        meson wrap install nlohmann_json
+        ```
+

+    - :octicons-question-24: [NuGet website](https://www.nuget.org)
+
+If you are using [NuGet](https://www.nuget.org), you can use the package [nlohmann.json](https://www.nuget.org/packages/nlohmann.json/)
+with
+
+```shell
+dotnet add package nlohmann.json
+```
+
+??? example
+
+    Probably the easiest way to use NuGet packages is through Visual Studio graphical interface. Right-click on a
+    project (any C++ project would do) in “Solution Explorer” and select “Manage NuGet Packages…”
+
+    ![](nuget/nuget-search-package.png)
+
+    Now you can click on “Browse” tab and find the package you like to install.
+
+    ![](nuget/nuget-select-package.png)
+
+    Most of the packages in NuGet gallery are .NET packages and would not be useful in a C++ project. Microsoft
+    recommends adding “native” and “nativepackage” tags to C++ NuGet packages to distinguish them, but even adding
+    “native” to search query would still show many .NET-only packages in the list.
+    
+    Nevertheless, after finding the package you want, click on “Install” button and accept confirmation dialogs.
+    After the package is successfully added to the projects, you should be able to build and execute the project
+    without the need for making any more changes to build settings.
+
+    !!! note
+
+        A few notes:
+    
+        - NuGet packages are installed per project and not system-wide. The header and binaries for the package are only
+          available to the project it is added to, and not other projects (obviously unless we add the package to those
+          projects as well)
+        - One of the many great things about your elegant work is that it is a header-only library, which makes
+          deployment very straightforward. In case of libraries which need binary deployment (`.lib`, `.dll` and `.pdb`
+          for debug info) the different binaries for each supported compiler version must be added to the NuGet package.
+          Some library creators cram binary versions for all supported Visual C++ compiler versions in the same package,
+          so a single package will support all compilers. Some others create a different package for each compiler
+          version (and you usually see things like “v140” or “vc141” in package name to clarify which VC++ compiler this
+          package supports).
+        - Packages can have dependency to other packages, and in this case, NuGet will install all dependencies as well
+          as the requested package recursively.
+
+    **What happens behind the scenes**
+
+    After you add a NuGet package, three changes occur in the project source directory. Of course, we could make these
+    changes manually instead of using GUI:
+    
+    ![](nuget/nuget-project-changes.png)
+    
+    1. A `packages.config` file will be created (or updated to include the package name if one such file already
+       exists). This file contains a list of the packages required by this project (name and minimum version) and must
+       be added to the project source code repository, so if you move the source code to a new machine, MSBuild/NuGet
+       knows which packages it has to restore (which it does automatically before each build).
+
+        ```xml
+        <?xml version="1.0" encoding="utf-8"?>
+        <packages>
+          <package id="nlohmann.json" version="3.5.0" targetFramework="native" />
+        </packages>
+        ```
+
+    2. A `packages` folder which contains actual files in the packages (these are header and binary files required for
+       a successful build, plus a few metadata files). In case of this library for example, it contains `json.hpp`:
+    
+        ![](nuget/nuget-package-content.png)
+    
+        !!! note
+
+            This directory should not be added to the project source code repository, as it will be restored before each
+            build by MSBuild/NuGet. If you go ahead and delete this folder, then build the project again, it will
+            magically re-appear!
+    
+    3. Project MSBuild makefile (which for Visual C++ projects has a .vcxproj extension) will be updated to include
+       settings from the package.
+    
+        ![](nuget/nuget-project-makefile.png)
+    
+        The important bit for us here is line 170, which tells MSBuild to import settings from
+        `packages\nlohmann.json.3.5.0\build\native\nlohmann.json.targets` file. This is a file the package creator
+        created and added to the package (you can see it is one of the two files I created in this repository, the other
+        just contains package attributes like name and version number). What does it contain?
+    
+        For our header-only repository, the only setting we need is to add our include directory to the list of
+        `AdditionalIncludeDirectories`:
+
+        ```xml    
+        <?xml version="1.0" encoding="utf-8"?>
+        <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
+            <ItemDefinitionGroup>
+                <ClCompile>
+                    <AdditionalIncludeDirectories>$(MSBuildThisFileDirectory)include;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
+                </ClCompile>
+            </ItemDefinitionGroup>
+        </Project>
+        ```
+
+        For libraries with binary files, we will need to add `.lib` files to linker inputs and add settings to copy
+        `.dll` and other redistributable files to output directory, if needed.
+    
+        There are other changes to the makefile as well:
+    
+        - Lines 165-167 add the `packages.config` as one of project files (so it is shown in Solution Explorer tree
+          view). It is added as None (no build action) and removing it wouldn’t affect build.
+    
+        - Lines 172-177 check to ensure the required packages are present. This will display a build error if package
+          directory is empty (for example when NuGet cannot restore packages because Internet connection is down).
+          Again, if you omit this section, the only change in build would be a more cryptic error message if build
+          fails.
+    
+        !!! note
+
+            Changes to .vcxproj makefile should also be added to project source code repository.
+    
+    As you can see, the mechanism NuGet uses to modify project settings is through MSBuild makefiles, so using NuGet
+    with other build systems and compilers (like CMake) as a dependency manager is either impossible or more problematic
+    than useful.

+## build2
+

+
+    package: **`nlohmann-json`**
+    library target: **`nlohmann-json%lib{json}`**
+    available in package repositories:
+      - [`cppget.org` (recommended)](https://cppget.org/nlohmann-json)
+      - [package's sources (for advanced users)](https://github.com/build2-packaging/nlohmann-json/)
+
+    - :octicons-tag-24: Available versions: current version and older versions since `3.7.3` (see [cppget.org](https://cppget.org/nlohmann-json))
+    - :octicons-rocket-24: The package is maintained and published by the `build2` community in [this repository](https://github.com/build2-packaging/nlohmann-json/).
+    - :octicons-file-24: File issues at the [package source repository](https://github.com/build2-packaging/nlohmann-json/issues/)
+    - :octicons-question-24: [`build2` website](https://build2.org)
+
+Note: [`build2`](https://build2.org) should not be considered as a standalone package-manager. It is a build-system + package manager + project manager, a set of tools that work hand-in-hand. `build2`-based projects do not rely on existing `CMake` scripts and the build scripts defining the project's targets are specific to `build2`.
+
+To use this package in an existing [`build2`](https://build2.org) project, the general steps are:
+
+  1. <details><summary>Make the package available to download from a package repository that provides it.</summary>
+
+      Your project's `repositories.manifest` specifies where the package manager will try to acquire packages by default. Make sure one of the repositories specified in this file provides `nlohmann-json` package.
+      The recommended open-source repository is [`cppget.org`](https://cppget.org/).
+
+      If the project has been created using [`bdep new`](https://build2.org/bdep/doc/bdep-new.xhtml), `cppget.org` is already specified in `repositories.manifest` but commented, just uncomment these lines:
+      ```
+      :
+      role: prerequisite
+      location: https://pkg.cppget.org/1/stable
+      ```
+      </details>
+
+  2. <details><summary>Add this package as dependency of your project.</summary>
+
+       In your project's `manifest` add the dependency to the package using `depends: nlohmann-json`. You could also add some [version constraints](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml#guide-add-remove-deps).
+       For example, to depend on the latest version available:
+       ```
+       depends: nlohmann-json
+       ```
+       </details>
+
+
+  3. <details><summary>Add this library as dependency of your target that uses it.</summary>
+
+      In the `buildfile` defining the target that will use this library:
+      
+        - import the target `lib{json}` from the `nlohmann-json` package, for example:
+            ```
+            import nljson = nlohmann-json%lib{json}
+            ```
+           
+        - then add the library's target as requirement for your target using it, for example:
+            ```
+            exe{example} : ... $nljson
+            ```
+           
+      </details>
+
+  4. <details><summary>Use the library in your project's code and build it.</summary>
+
+      At this point, assuming your project is initialized in a build-configuration, any `b` or `bdep update` command that will update/build the project will also acquire the missing dependency automatically, then build it and link it with your target.
+
+      If you just want to synchronize dependencies for all your configurations to download the ones you just added:
+        ```
+        bdep sync -af
+        ```
+      </details>
+
+??? example "Example: from scratch, using `build2`'s [`bdep new` command](https://build2.org/bdep/doc/bdep-new.xhtml)"
+
+    1. Create a new executable project "example" (see [`bdep new` command details](https://build2.org/bdep/doc/bdep-new.xhtml) for the various options to create a new project):
+
+        ```shell
+        bdep new example
+        ```
+
+    2. Edit these files by replacing their content:
+
+        - `example/repositories.manifest`: Enable acquiring packages from https://cppget.org by uncommenting the related lines:
+
+            ```make title="project's `repositories.manifest`"
+            --8<-- "integration/build2/repositories.manifest"
+            ```
+
+        - `example/manifest`: Add the latest version of the `nlohmann-json` package as dependency to the project:
+
+            ```make title="project's `manifest`"
+            --8<-- "integration/build2/manifest"
+            ```
+
+        - `example/example/buildfile`: import the library's target to be used as requirement for building the executable target `exe{example}`:
+
+            ```make title="project's `buildfile`"
+            --8<-- "integration/build2/buildfile"
+            ```
+
+        - `example/example/example.cxx`: `bdep new` generates a "hello world" by default, replace it by this:
+
+            ```cpp title="example.cxx"
+            --8<-- "integration/build2/example.cpp"
+            ```
+
+        - `example/example/testscript`: (optional) if you want to be able to test that executable's output is correct using `b test`:
+
+            ```cpp title="`testscript` checking the output of the program"
+            --8<-- "integration/build2/testscript"
+            ```
+
+
+    3. Initialize the project in a default C/C++ build configuration directory, then build and test:
+
+        ```shell
+        cd example/
+
+        # create default C/C++ build configuration in ../example-myconfig/, initialize the project in it (downloads it's dependencies in it too)
+        bdep init -C @myconfig cc
+
+        # build only,
+        b
+
+        # or build and test the executable's output, will only work if the `testscript` is correct
+        b test
+
+        ```

+## Buckaroo
+
+If you are using [Buckaroo](https://buckaroo.pm), you can install this library's module with `buckaroo add github.com/buckaroo-pm/nlohmann-json`. There is a demo repo [here](https://github.com/njlr/buckaroo-nholmann-json-example).
+
+!!! warning
+
+    The module is outdated as the respective [repository](https://github.com/buckaroo-pm/nlohmann-json) has not been
+    updated in years.
+
+## CocoaPods
+
+If you are using [CocoaPods](https://cocoapods.org), you can use the library by adding pod `"nlohmann_json", '~>3.1.2'`
+to your podfile (see [an example](https://bitbucket.org/benman/nlohmann_json-cocoapod/src/master/)). Please file issues
+[here](https://bitbucket.org/benman/nlohmann_json-cocoapod/issues?status=new&status=open).
+
+## npm
+
+This project does not publish an official [npm](https://www.npmjs.com) package. The npm package
+[`nlohmann-json`](https://www.npmjs.com/package/nlohmann-json) (or similarly named packages) is not maintained or
+endorsed by this project. Use one of the package managers listed above, or integrate the single header directly.
+
+## ESP-IDF and PlatformIO
+
+There is no official package published to the [ESP-IDF Component Registry](https://components.espressif.com) or the
+[PlatformIO Registry](https://registry.platformio.org). A community-maintained fork,
+[Johboh/nlohmann-json](https://github.com/Johboh/nlohmann-json), publishes this library to both registries on each
+new release and can be used as an unofficial component/package for ESP-IDF and PlatformIO projects. As the library
+is header-only, it can otherwise be used directly by adding its `include/` directory to your component's/project's
+include paths, like any other integration method described on this page.

+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 1.33, compute F0 and the Schlick-approximated Fresnel reflectance at 60° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜><think>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=1.33
+     = ((1.33-1)/(1.33+1))² = (0.141631)² = 0.0200593
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 60° = 0.5
+  (1 - 0.5)⁵ = 0.03125
+  F = 0.0200593 + 0.979941·0.03125 = 0.0506825
+
+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 60-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 60° we are well into the grazing regime, where the ⁵ power is doing all the work.</think>F0 = 0.0200593 (2.01% reflectance head-on).
+F(60°) = 0.0506825 (5.07%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+Note 60° is grazing: the (1-cosθ)⁵ term dominates and reflectance climbs steeply toward 1 from here. For metals this formulation does not apply directly: F0 becomes a per-channel tinted value from the complex refractive index rather than a single scalar.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>I have 12 overlapping transparent quads (smoke sprites). Depending on camera angle some of them vanish behind others or pop as I orbit. `transparent: true` is set on all of them. What is happening?<｜Assistant｜><think>Two distinct mechanisms get conflated here, and the fix differs.
+
+**Depth write.** With `transparent: true` three.js still writes depth by default. A near sprite drawn first writes its depth, and a farther sprite drawn later fails the depth test and is discarded entirely — so it 'vanishes'. That is not a sorting problem, it is a depth-write problem.
+
+**Sort order.** Alpha blending is not commutative: over(a, over(b, c)) ≠ over(b, over(a, c)). So transparent geometry must be drawn back-to-front. three.js does sort transparent objects by distance, but per *object*, using the object's origin — not per triangle. 12 overlapping quads whose origins are close together, or that interpenetrate, will sort inconsistently and pop as the camera orbits and the origin ordering flips.
+
+So: 'vanishes' → depthWrite. 'pops as I orbit' → per-object sort granularity.
+
+For 12 quads, turning off depth writing plus the built-in sort is usually enough.
+
+If the sprites are opaque-ish with hard edges, alpha *testing* sidesteps the whole problem, because cutout geometry can go in the opaque pass and be depth-sorted by the hardware for free.</think>Two separate bugs, and they need different fixes.
+
+**Sprites vanishing → depth writes.** `transparent: true` does not stop depth writing. A near quad writes depth, then a farther one fails the test and is culled. Set `depthWrite: false` on the transparent material (keep `depthTest: true` so opaque geometry still occludes them).
+
+**Popping as you orbit → sort granularity.** three.js sorts transparent objects back-to-front by object origin, not per triangle. With 12 overlapping quads the origin ordering flips as you move and the blend order changes visibly.
+
+Options:
+- `depthWrite: false` — fixes the vanishing immediately, do this first.
+- Use `renderOrder` to pin an explicit order when you know the layering.
+- At only 12 sprites the built-in sort is fine once depthWrite is off.
+- If the alpha is mostly hard-edged, use `alphaTest` instead of transparency and let them render in the opaque pass — the depth buffer then sorts them for free.<｜end▁of▁sentence｜>

Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate a Catmull-Rom spline at t=0.81 on the segment between P1 and P2, with control points P0=[5.12, -1.85], P1=[-2.77, -4.08], P2=[0.05, 4.22], P3=[0.84, -5.6] and tension τ=0.5. Why does this curve pass through its control points when a B-spline does not?<｜Assistant｜><think>Catmull-Rom is a cubic Hermite spline whose tangents are estimated from the neighbouring points:
+  m1 = τ(P2 - P0) = 0.5·[-5.07, 6.07] = [-2.535, 3.035]
+  m2 = τ(P3 - P1) = 0.5·[3.61, -1.52] = [1.805, -0.76]
+
+Hermite basis at t=0.81 (t²=0.6561, t³=0.531441):
+  h00 = 2t³-3t²+1 = 0.094582
+  h10 = t³-2t²+t = 0.029241
+  h01 = -2t³+3t² = 0.905418
+  h11 = t³-t²    = -0.124659
+  (they sum on the position terms: h00 + h01 = 1)
+
+P(t) = h00·P1 + h10·m1 + h01·P2 + h11·m2
+     = 0.094582·[-2.77, -4.08] + 0.029241·[-2.535, 3.035] + 0.905418·[0.05, 4.22] + -0.124659·[1.805, -0.76]
+     = [-0.515857, 3.61846]
+
+Interpolation vs approximation: at t=0 the basis reduces to h00=1 and everything else 0, giving exactly P1; at t=1, h01=1 giving exactly P2. So the curve is *interpolating* by construction. A uniform cubic B-spline instead weights each control point by 1/6, 4/6, 1/6 at the knots, so it passes near but not through them — it trades interpolation for C² continuity, whereas Catmull-Rom is only C¹.</think>P(0.81) = [-0.515857, 3.61846]
+
+Tangents m1 = [-2.535, 3.035], m2 = [1.805, -0.76]; Hermite weights h00=0.094582, h10=0.029241, h01=0.905418, h11=-0.124659.
+
+Catmull-Rom interpolates because its Hermite basis collapses to exactly P1 at t=0 and exactly P2 at t=1. A uniform B-spline weights the knots 1/6, 4/6, 1/6 and so only approximates them — buying C² continuity in exchange, where Catmull-Rom gives you only C¹. That is the trade: pass through the points, or have continuous curvature. three.js `CatmullRomCurve3` is the former.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 1.0, compute F0 and the Schlick-approximated Fresnel reflectance at 45° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜><think>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=1.0
+     = ((1.0-1)/(1.0+1))² = (0)² = 0
+
+An IOR of 1.0 means no index mismatch at all, so F0 = 0 and the surface is invisible — worth sanity-checking that this is intended.
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 45° = 0.707107
+  (1 - 0.707107)⁵ = 0.00215549
+  F = 0 + 1·0.00215549 = 0.00215549
+
+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 60-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 45° we are in the flat part of the curve, where F is still close to F0.</think>F0 = 0 (0% reflectance head-on).
+F(45°) = 0.00215549 (0.216%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+At 45° you are still on the flat part of the curve, close to F0. Careful with IOR 1.0 — zero index mismatch means no reflection at all.<｜end▁of▁sentence｜>
+
+Ambiguity is the type of meaning in which a phrase, statement, or resolution is not explicitly defined, making several interpretations plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved, according to a rule or process with a finite number of steps. (The prefix ambi-  reflects the idea of "two," as in "two meanings.")
+
+The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately obvious), whereas with vague information it is difficult to form any interpretation at the desired level of specificity.
+
+Linguistic forms 
+Lexical ambiguity is contrasted with semantic ambiguity. The former represents a choice between a finite number of known and meaningful context-dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning. This form of ambiguity is closely related to vagueness.
+
+Ambiguity in human language is argued to reflect principles of efficient communication. Languages that communicate efficiently will avoid sending information that is redundant with information provided in the context. This can be shown mathematically to result in a system which is ambiguous when context is neglected. In this way, ambiguity is viewed as a generally useful feature of a linguistic system. 
+
+Linguistic ambiguity can be a problem in law, because the interpretation of written documents and oral agreements is often of paramount importance.
+
+Lexical ambiguity 
+The lexical ambiguity of a word or phrase applies to it having more than one meaning in the language to which the word belongs. "Meaning" here refers to whatever should be represented by a good dictionary. For instance, the word "bank" has several distinct lexical definitions, including "financial institution" and "edge of a river". Or consider "apothecary". One could say "I bought herbs from the apothecary". This could mean one actually spoke to the apothecary (pharmacist) or went to the apothecary (pharmacy).
+
+The context in which an ambiguous word is used often makes it clearer which of the meanings is intended. If, for instance, someone says "I put $100 in the bank", most people would not think someone used a shovel to dig in the mud. However, some linguistic contexts do not provide sufficient information to make a used word clearer.
+
+Lexical ambiguity can be addressed by algorithmic methods that automatically associate the appropriate meaning with a word in context, a task referred to as word-sense disambiguation.
+
+The use of multi-defined words requires the author or speaker to clarify their context, and sometimes elaborate on their specific intended meaning (in which case, a less ambiguous term should have been used). The goal of clear concise communication is that the receiver(s) have no misunderstanding about what was meant to be conveyed. An exception to this could include a politician whose "weasel words" and obfuscation are necessary to gain support from multiple constituents with mutually exclusive conflicting desires from his or her candidate of choice. Ambiguity is a powerful tool of political science.
+
+More problematic are words whose multiple meanings express closely related concepts. "Good", for example, can mean "useful" or "functional" (That's a good hammer), "exemplary" (She's a good student), "pleasing" (This is good soup), "moral" (a good person versus the lesson to be learned from a story), "righteous", etc. "I have a good daughter" is not clear about which sense is intended. The various ways to apply prefixes and suffixes can also create ambiguity ("unlockable" can mean "capable of being opened" or "impossible to lock").
+
+Semantic and syntactic ambiguity 
+
+Semantic ambiguity occurs when a word, phrase or sentence, taken out of context, has more than one interpretation. In "We saw her duck" (example due to Richard Nordquist), the words "her duck" can refer either
+
+ to the person's bird (the noun "duck", modified by the possessive pronoun "her"), or
+ to a motion she made (the verb "duck", the subject of which is the objective pronoun "her", object of the verb "saw").
+
+Syntactic ambiguity arises when a sentence can have two (or more) different meanings because of the structure of the sentence—its syntax. This is often due to a modifying expression, such as a prepositional phrase, the application of which is unclear. "He ate the cookies on the couch", for example, could mean that he ate those cookies that were on the couch (as opposed to those that were on the table), or it could mean that he was sitting on the couch when he ate the cookies. "To get in, you will need an entrance fee of $10 or your voucher and your drivers' license." This could mean that you need EITHER ten dollars OR BOTH your voucher and your license. Or it could mean that you need your license AND you need EITHER ten dollars OR a voucher. Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity.
+For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar.
+
+Usually, semantic and syntactic ambiguity go hand in hand. The sentence "We saw her duck" is also syntactically ambiguous. Conversely, a sentence like "He ate the cookies on the couch" is also semantically ambiguous. Rarely, but occasionally, the different parsings of a syntactically ambiguous phrase result in the same meaning. For example, the command "Cook, cook!" can be parsed as "Cook (noun used as vocative), cook (imperative verb form)!", but also as "Cook (imperative verb form), cook (noun used as vocative)!". It is more common that a syntactically unambiguous phrase has a semantic ambiguity; for example, the lexical ambiguity in "Your boss is a funny man" is purely semantic, leading to the response "Funny ha-ha or funny peculiar?"
+
+Spoken language can contain many more types of ambiguities which are called phonological ambiguities, where there is more than one way to compose a set of sounds into words. For example, "ice cream" and "I scream". Such ambiguity is generally resolved according to the context. A mishearing of such, based on incorrectly resolved ambiguity, is called a mondegreen.
+
+Philosophy 
+Philosophers (and other users of logic) spend a lot of time and effort searching for and removing (or intentionally adding) ambiguity in arguments because it can lead to incorrect conclusions and can be used to deliberately conceal bad arguments. For example, a politician might say, "I oppose taxes which hinder economic growth", an example of a glittering generality. Some will think they oppose taxes in general because they hinder economic growth. Others may think they oppose only those taxes that they believe will hinder economic growth. In writing, the sentence can be rewritten to reduce possible misinterpretation, either by adding a comma after "taxes" (to convey the first sense) or by changing "which" to "that" (to convey the second sense) or by rewriting it in other ways. The devious politician hopes that each constituent will interpret the statement in the most desirable way, and think the politician supports everyone's opinion. However, the opposite can also be true—an opponent can turn a positive statement into a bad one if the speaker uses ambiguity (intentionally or not). The logical fallacies of amphiboly and equivocation rely heavily on the use of ambiguous words and phrases.
+
+In continental philosophy (particularly phenomenology and existentialism), there is much greater tolerance of ambiguity, as it is generally seen as an integral part of the human condition. Martin Heidegger argued that the relation between the subject and object is ambiguous, as is the relation of mind and body, and part and whole. In Heidegger's phenomenology, Dasein is always in a meaningful world, but there is always an underlying background for every instance of signification. Thus, although some things may be certain, they have little to do with Dasein's sense of care and existential anxiety, e.g., in the face of death. In calling his work Being and Nothingness an "essay in phenomenological ontology" Jean-Paul Sartre follows Heidegger in defining the human essence as ambiguous, or relating fundamentally to such ambiguity. Simone de Beauvoir tries to base an ethics on Heidegger's and Sartre's writings (The Ethics of Ambiguity), where she highlights the need to grapple with ambiguity: "as long as there have been philosophers and they have thought, most of them have tried to mask it ... And the ethics which they have proposed to their disciples has always pursued the same goal. It has been a matter of eliminating the ambiguity by making oneself pure inwardness or pure externality, by escaping from the sensible world or being engulfed by it, by yielding to eternity or enclosing oneself in the pure moment." Ethics cannot be based on the authoritative certainty given by mathematics and logic, or prescribed directly from the empirical findings of science. She states: "Since we do not succeed in fleeing it, let us, therefore, try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting". Other continental philosophers suggest that concepts such as life, nature, and sex are ambiguous. Corey Anton has argued that we cannot be certain what is separate from or unified with something else: language, he asserts, divides what is not, in fact, separate. Following Ernest Becker, he argues that the desire to 'authoritatively disambiguate' the world and existence has led to numerous ideologies and historical events such as genocide. On this basis, he argues that ethics must focus on 'dialectically integrating opposites' and balancing tension, rather than seeking a priori validation or certainty. Like the existentialists and phenomenologists, he sees the ambiguity of life as the basis of creativity.
+
+Literature and rhetoric 
+In literature and rhetoric, ambiguity can be a useful tool. Groucho Marx's classic joke depends on a grammatical ambiguity for its humor, for example: "Last night I shot an elephant in my pajamas. How he got in my pajamas, I'll never know". Songs and poetry often rely on ambiguous words for artistic effect, as in the song title "Don't It Make My Brown Eyes Blue" (where "blue" can refer to the color, or to sadness).
+
+In the narrative, ambiguity can be introduced in several ways: motive, plot, character. F. Scott Fitzgerald uses the latter type of ambiguity with notable effect in his novel The Great Gatsby.
+
+Mathematical notation 
+Mathematical notation is a helpful tool that eliminates a lot of misunderstandings associated with natural language in physics and other sciences. Nonetheless, there are still some inherent ambiguities due to lexical, syntactic, and semantic reasons that persist in mathematical notation.
+
+Names of functions 
+The ambiguity in the style of writing a function should not be confused with a multivalued function, which can (and should) be defined in a deterministic and unambiguous way. Several special functions still do not have established notations. Usually, the conversion to another notation requires to scale the argument or the resulting value; sometimes, the same name of the function is used, causing confusions. Examples of such underestablished functions:
+ Sinc function
+ Elliptic integral of the third kind; translating elliptic integral form MAPLE to Mathematica, one should replace the second argument to its square, see Talk:Elliptic integral#List of notations; dealing with complex values, this may cause problems.
+ Exponential integral
+ Hermite polynomial
+
+Expressions 
+Ambiguous expressions often appear in physical and mathematical texts.
+It is common practice to omit multiplication signs in mathematical expressions. Also, it is common to give the same name to a variable and a function, for example, . Then, if one sees , there is no way to distinguish whether it means  multiplied by , or function  evaluated at argument equal to . In each case of use of such notations, the reader is supposed to be able to perform the deduction and reveal the true meaning.
+
+Creators of algorithmic languages try to avoid ambiguities. Many algorithmic languages (C++ and Fortran) require the character * as symbol of multiplication. The Wolfram Language used in Mathematica allows the user to omit the multiplication symbol, but requires square brackets to indicate the argument of a function; square brackets are not allowed for grouping of expressions. Fortran, in addition, does not allow use of the same name (identifier) for different objects, for example, function and variable; in particular, the expression f=f(x) is qualified as an error.
+
+The order of operations may depend on the context. In most programming languages, the operations of division and multiplication have equal priority and are executed from left to right. Until the last century, many editorials assumed that multiplication is performed first, for example,  is interpreted as ; in this case, the insertion of parentheses is required when translating the formulas to an algorithmic language. In addition, it is common to write an argument of a function without parenthesis, which also may lead to ambiguity.
+In the scientific journal style, one uses roman letters to denote elementary functions, whereas variables are written using italics.
+For example, in mathematical journals the expression
+
+does not denote the sine function, but the
+product of the three variables
+,
+,
+, although in the informal notation of a slide presentation it may stand for .
+
+Commas in multi-component subscripts and superscripts are sometimes omitted; this is also potentially ambiguous notation.
+For example, in the notation , the reader can only infer from the context whether it means a single-index object, taken with the subscript equal to product of variables ,  and , or it is an indication to a trivalent tensor.
+
+Examples of potentially confusing ambiguous mathematical expressions 
+An expression such as  can be understood to mean either  or . Often the author's intention can be understood from the context, in cases where only one of the two makes sense, but an ambiguity like this should be avoided, for example by writing  or .
+
+The expression  means  in several texts, though it might be thought to mean , since  commonly means . Conversely,  might seem to mean , as this exponentiation notation usually denotes function iteration: in general,  means . However, for trigonometric and hyperbolic functions, this notation conventionally means exponentiation of the result of function application.
+
+The expression  can be interpreted as meaning ; however, it is more commonly understood to mean .
+
+Notations in quantum optics and quantum mechanics 
+It is common to define the coherent states in quantum optics with  and states with fixed number of photons with . Then, there is an "unwritten rule": the state is coherent if there are more Greek characters than Latin characters in the argument, and photon state if the Latin characters dominate. The ambiguity becomes even worse, if  is used for the states with certain value of the coordinate, and  means the state with certain value of the momentum, which may be used in books on quantum mechanics. Such ambiguities easily lead to confusions, especially if some normalized adimensional, dimensionless variables are used. Expression  may mean a state with single photon, or the coherent state with mean amplitude equal to 1, or state with momentum equal to unity, and so on. The reader is supposed to guess from the context.
+
+Ambiguous terms in physics and mathematics 
+Some physical quantities do not yet have established notations; their value (and sometimes even dimension, as in the case of the Einstein coefficients), depends on the system of notations. Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "... Only in the context of a proposition has a name meaning."
+
+A highly confusing term is gain. For example, the sentence "the gain of a system should be doubled", without context, means close to nothing.
+
+ It may mean that the ratio of the output voltage of an electric circuit to the input voltage should be doubled.
+ It may mean that the ratio of the output power of an electric or optical circuit to the input power should be doubled.
+ It may mean that the gain of the laser medium should be doubled, for example, doubling the population of the upper laser level in a quasi-two level system (assuming negligible absorption of the ground-state).
+
+The term intensity is ambiguous when applied to light. The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term.
+
+Also, confusions may be related with the use of atomic percent as measure of concentration of a dopant, or resolution of an imaging system, as measure of the size of the smallest detail which still can be resolved at the background of statistical noise. See also Accuracy and precision and its talk.
+
+The Berry paradox arises as a result of systematic ambiguity in the meaning of terms such as "definable" or "nameable". Terms of this kind give rise to vicious circle fallacies. Other terms with this type of ambiguity are: satisfiable, true, false, function, property, class, relation, cardinal, and ordinal.
+
+Mathematical interpretation of ambiguity 
+
+In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example,  leaves open what the value of X is—while its opposite is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system—such as , which has no solution.
+
+Logical ambiguity and self-contradiction is analogous to visual ambiguity and impossible objects, such as the Necker cube and impossible cube, or many of the drawings of M. C. Escher.
+
+Constructed language 
+
+Some languages have been created with the intention of avoiding ambiguity, especially lexical ambiguity. Lojban and Loglan are two related languages which have been created for this, focusing chiefly on syntactic ambiguity as well. The languages can be both spoken and written. These languages are intended to provide a greater technical precision over big natural languages, although historically, such attempts at language improvement have been criticized. Languages composed from many diverse sources contain much ambiguity and inconsistency. The many exceptions to syntax and semantic rules are time-consuming and difficult to learn.
+
+Biology 
+In structural biology, ambiguity has been recognized as a problem for studying protein conformations. The analysis of a protein three-dimensional structure consists in dividing the macromolecule into subunits called domains. The difficulty of this task arises from the fact that different definitions of what a domain is can be used (e.g. folding autonomy, function, thermodynamic stability, or domain motions), which sometimes results in a single protein having different—yet equally valid—domain assignments.
+
+Christianity and Judaism 
+Christianity and Judaism employ the concept of paradox synonymously with "ambiguity". Many Christians and Jews endorse Rudolf Otto's description of the sacred as 'mysterium tremendum et fascinans', the awe-inspiring mystery which fascinates humans. The apocryphal Book of Judith is noted for the "ingenious ambiguity" expressed by its heroine; for example, she says to the villain of the story, Holofernes, "my lord will not fail to achieve his purposes", without specifying whether my lord refers to the villain or to God.
+
+The orthodox Catholic writer G. K. Chesterton regularly employed paradox to tease out the meanings in common concepts which he found ambiguous or to reveal meaning often overlooked or forgotten in common phrases: the title of one of his most famous books, Orthodoxy (1908), itself employed such a paradox.
+
+Music 
+In music, pieces or sections which confound expectations and may be or are interpreted simultaneously in different ways are ambiguous, such as some polytonality, polymeter, other ambiguous meters or rhythms, and ambiguous phrasing, or (Stein 2005, p. 79) any aspect of music. The music of Africa is often purposely ambiguous. To quote Sir Donald Francis Tovey (1935, p. 195), "Theorists are apt to vex themselves with vain efforts to remove uncertainty just where it has a high aesthetic value."
+
+Visual art 
+
+In visual art, certain images are visually ambiguous, such as the Necker cube, which can be interpreted in two ways. Perceptions of such objects remain stable for a time, then may flip, a phenomenon called multistable perception.
+The opposite of such ambiguous images are impossible objects.
+
+Pictures or photographs may also be ambiguous at the semantic level: the visual image is unambiguous, but the meaning and narrative may be ambiguous: is a certain facial expression one of excitement or fear, for instance?
+
+Social psychology and the bystander effect 
+In social psychology, ambiguity is a factor used in determining peoples' responses to various situations. High levels of ambiguity in an emergency (e.g. an unconscious man lying on a park bench) make witnesses less likely to offer any sort of assistance, due to the fear that they may have misinterpreted the situation and acted unnecessarily. Alternately, non-ambiguous emergencies (e.g. an injured person verbally asking for help) elicit more consistent intervention and assistance. With regard to the bystander effect, studies have shown that emergencies deemed ambiguous trigger the appearance of the classic bystander effect (wherein more witnesses decrease the likelihood of any of them helping) far more than non-ambiguous emergencies.
+
+Computer science 
+In computer science, the SI prefixes kilo-, mega- and giga- were historically used in certain contexts to mean either the first three powers of 1024 (1024, 10242 and 10243) contrary to the metric system in which these units unambiguously mean one thousand, one million, and one billion. This usage is particularly prevalent with electronic memory devices (e.g. DRAM) addressed directly by a binary machine register where a decimal interpretation makes no practical sense.
+
+Subsequently, the Ki, Mi, and Gi prefixes were introduced so that binary prefixes could be written explicitly, also rendering k, M, and G unambiguous in texts conforming to the new standard—this led to a new ambiguity in engineering documents lacking outward trace of the binary prefixes (necessarily indicating the new style) as to whether the usage of k, M, and G remains ambiguous (old style) or not (new style). 1 M (where M is ambiguously 1,000,000 or 1,048,576) is less uncertain than the engineering value 1.0e6 (defined to designate the interval 950,000 to 1,050,000). As non-volatile storage devices begin to exceed 1 GB in capacity (where the ambiguity begins to routinely impact the second significant digit), GB and TB almost always mean 109 and 1012 bytes.

+ [ 1.0841  0.9574  0.    ]
+ [ 0.      0.      2.15  ]]
+
+The failure is geometric, not numerical. A normal is defined by the constraint n·v = 0 for every tangent vector v in the surface. Tangents transform as v' = M v. If we also sent n' = M n we would need (M n)·(M v) = 0, i.e. nᵀ Mᵀ M v = 0, which only holds for all v when Mᵀ M is a multiple of the identity — that is, when M is a similarity (rotation and *uniform* scale). Non-uniform scale breaks it.
+
+Solving nᵀ A M v = 0 against nᵀ v = 0 for all v gives AᵀM = I, so A = (M⁻¹)ᵀ.
+
+(M⁻¹)ᵀ =
+[[ 0.4299 -0.4868  0.    ]
+ [ 0.2941  0.7115  0.    ]
+ [ 0.      0.      0.4651]]
+
+Wrong way, M·n = [0.786341, 1.35422, 0.746699] → normalised [0.453255, 0.780584, 0.430404]
+Right way, (M⁻¹)ᵀ·n = [0.0338045, 0.629736, 0.161536] → normalised [0.0519269, 0.967333, 0.248134]
+Angle between them: 27.6969°.
+
+Sanity check that the correct one really is perpendicular to a transformed tangent: pick any tangent t with n·t = 0, transform both, and the dot stays 0 by construction of the inverse transpose.</think>Correct normal: [0.0519269, 0.967333, 0.248134] (using the **normal matrix** (M⁻¹)ᵀ).
+Using M directly gives [0.453255, 0.780584, 0.430404], off by 27.6969°.
+
+Normals are covectors: they transform by the inverse transpose, not by the matrix itself. Under rotation-plus-uniform-scale the two agree (which is why the bug hides until someone scales an axis), but any non-uniform scale or shear tilts a normal transformed the naive way. This is exactly what three.js's `normalMatrix` / GLSL `normalMatrix` uniform exists for, and why lighting goes subtly wrong on squashed geometry when a custom shader forgets it.<｜end▁of▁sentence｜>
+
+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>I need to render 200,000 copies of a 500-triangle model. Compare separate Meshes, merged geometry, and InstancedMesh — which should I use and why?<｜Assistant｜><think>Total triangle load is 200,000 × 500 = 100,000,000 triangles either way, so the geometry cost is fixed. What differs is CPU overhead and flexibility.
+
+**200,000 separate Meshes.** One draw call each. Browsers manage roughly 1,000-5,000 draw calls per frame at 60fps before the CPU becomes the bottleneck, and each also costs a matrix update and a frustum-cull test in the three.js render loop. At 200,000 this is catastrophic.
+
+**Merged geometry.** One draw call, 100,000,000 triangles in one buffer. Cheapest possible CPU cost, but the copies lose independent transforms — moving one means rewriting the vertex buffer — and you lose per-object frustum culling, so all 100,000,000 triangles are submitted even when most are off screen.
+
+**InstancedMesh.** One draw call, one copy of the geometry, plus a per-instance matrix buffer (200,000 × 16 floats = 12.2 MB). Per-instance transforms stay independent and cheap to update. The tradeoff is that culling is all-or-nothing per InstancedMesh unless you sort and manage `count` yourself.
+
+At 500 triangles per copy the geometry is heavy enough that GPU throughput, not draw calls, becomes the limit.</think>**Use InstancedMesh.**
+
+All three submit the same 100,000,000 triangles, so the difference is CPU overhead:
+
+| approach | draw calls | per-copy transform | culling |
+|---|---|---|---|
+| 200,000 Meshes | 200,000 | yes | per object |
+| merged | 1 | no | none |
+| InstancedMesh | 1 | yes | per batch |
+
+200,000 separate meshes means 200,000 draw calls; the practical browser budget is roughly 1,000-5,000 per frame, so that is far past the limit. Merging gets you to one call but freezes the copies into a single buffer.
+
+InstancedMesh gives you the single draw call *and* keeps per-instance matrices (12.2 MB for 200,000 instances). Update with `setMatrixAt(i, m)` and set `instanceMatrix.needsUpdate = true`.
+
+At 100,000,000 triangles total you will be GPU-bound rather than draw-call-bound, so also add an LOD or reduce 500 triangles per copy — instancing alone will not save you.
+
+Caveat: frustum culling becomes per-InstancedMesh, not per instance. If the copies are spread over a large area, split them into several InstancedMeshes by region so off-screen groups can be culled.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a coding agent working inside the webgpu-samples repository. Use the provided tools to inspect and modify the codebase. Verify your changes by running the project's checks before reporting completion.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.
+

The failure in `sample/samplerParameters/meta.ts` was a missing input normalisation, not the doc I first assumed — the sibling module in `sample/animometer/main.ts` already normalises before dispatch and this one skipped it.

+Before the creation of towns and cities, established authority did not exist. It was after the institution of authority that anarchistic ideas were espoused as a reaction. The most notable precursors to anarchism in the ancient world were in China and Greece. In China, philosophical anarchism (the discussion on the legitimacy of the state) was delineated by Taoist philosophers Zhuang Zhou and Laozi. Alongside Stoicism, Taoism has been said to have had "significant anticipations" of anarchism.

+LAuvergne ( ou Euvarnhà) est une région historique et culturelle située dans le centre de la France, au cœur du Massif central.
+
+De 1941 à 1946 et de 1956 à 2015, la région Auvergne fut également une région administrative française composée des quatre départements de l'Allier, du Cantal, de la Haute-Loire et du Puy-de-Dôme. Sa plus grande ville, Clermont-Ferrand, en était le chef-lieu. Cette région a été supprimée le  par la loi sur l'Acte  de la décentralisation. Les départements qui la composaient font maintenant partie de la nouvelle région Auvergne-Rhône-Alpes.
+
+Avec plus de  d'histoire, l'Auvergne est une des plus anciennes régions de France et une des mieux identifiées. Toutefois, son territoire est perçu de façon variable et le géographe Pierre Bonnaud compte quatre définitions possibles pour les contours de la région. Ainsi, en plus de l’ancienne région administrative, il y a deux Auvergne historiques. La première a existé jusqu'au  et correspond à la cité des Arvernes ou Arvernie qui se perpétua avec le diocèse primitif de Clermont. La constitution du duché de Bourbon confisqua le nord de son territoire et laissa une province plus petite au .
+
+Enfin, dans limaginaire parisien, l'Auvergne apparaît souvent comme une région plus vaste. Au  et au  une vague d'immigration venant d'Auvergne, de l'Aveyron, de la Lozère et de la montagne limousine a submergé la capitale. Elle y a imposé son folklore et a été identifiée comme celle des « Auvergnats de Paris » ou « bougnats ». Il n'est pas rare que toute la partie sud du Massif central soit ainsi assimilée à l'Auvergne. Clin d’œil à l'histoire, cette aire territoriale fait penser à celle des peuples vassaux des Arvernes sous l’Antiquité.
+
+Même si cette région n’a plus de concrétisation administrative, son histoire et sa géographie lui donnent une profonde cohérence. Sa métropole, Clermont-Ferrand, la polarise en totalité et confirme cette unité.
+
+Dénomination et blason 
+L'Auvergne tient son nom du peuple des Arvernes, dont le nom est généralement interprété comme « ceux qui vivent devant des terres plantées d'aulnes » par composition du préfixe gaulois are (« près de », « devant ») et de verno ou uerno (« aulnes » ou « aulnaies »). Le nom Auvergne est écrit en roman médiéval ou en auvergnat Arvernha, Auvernha, Auvernhe ou dans le nord de la Lozère Alvernhe. La chaîne évolutive de ce toponyme est Arvernia - Alvernia - Alvernha - Auvernha - Auvergne.
+
+Le blason de l'Auvergne, d’or au gonfanon de gueules bordé de sinople, a été pris par les comtes d'Auvergne depuis au moins le , les sceaux et l'iconographie des comtes  et  présentant déjà le gonfanon pour emblème de l'Auvergne. L'origine de cet emblème n'est pas certaine. Il pourrait s'agir de la bannière de l'abbé d’Aurillac autour de laquelle se rallièrent les chevaliers de la nation d'Auvergne lors de la conquête de Jérusalem ou alors de celle d'Eustache III, aïeul d'Adélaïde de Brabant, la mère du comte. Eustache III avait le titre de comte de Boulogne-sur-Mer et était le frère de Godefroy de Bouillon.
+
+Histoire
+
+Pays des Arvernes 
+
+L'Auvergne doit son nom au peuple gaulois des Arvernes. C'était l'une des tribus les plus puissantes et les plus riches de la Gaule antique. Cette prédominance s’explique par plusieurs raisons. Le territoire arverne donnait à ses occupants une totale autonomie agricole, il se composait au centre de la grande plaine très fertile de la Limagne, de coteaux fruiticoles sur le pourtour et enfin de grandes prairies de moyenne montagne idéales pour l'élevage. Ces zones d'autosubsistance étaient noyées dans un dense massif forestier qui fournissait l'énergie nécessaire à la mise en place d'industries prospères : la céramique et la métallurgie. Lezoux devint à l'époque gallo-romaine un des plus grands centres de production de poteries (en particulier sigillées) d'Europe. Ces poteries font partie du matériel archéologique courant que l'on retrouve partout dans le nord de l'Europe et servent à la datation des lieux fouillés. L'exploitation de nombreuses mines d'or, d'argent et d'autres métaux (exploitées depuis 400  au minimum) permit de faire de la métallurgie, de la forge et de l'orfèvrerie (en particulier du travail du cuivre) une grande spécialité arverne. Dans la Guerre des Gaules de César, Vercingétorix est décrit avec « une grande armure faite de nombreuses pièces d'argent assemblées et reflétant le soleil ». Les Arvernes frappaient leur propre monnaie et multipliaient les échanges commerciaux avec les tribus voisines (moins de  connues pour  gaulois). Ils développèrent au centre du monde gaulois un commerce est-ouest et nord-sud engendrant une grande richesse. La puissance militaire des arvernes était importante, elle s’appuyait sur un territoire difficile à atteindre par les armées adverses car entouré sur quasiment tous ses côtés par des massifs montagneux (seul le nord était ouvert sur les plaines du centre de la Gaule). Enfin, il y avait au sommet du puy de Dôme un sanctuaire d'une importance majeure pour plusieurs nations gauloises qui s'y retrouvaient.
+
+Les recherches archéologiques les plus récentes situent la capitale des Arvernes de la fin du second âge du fer à l'oppidum de Corent.
+
+Strabon décrit une royauté arverne puissante qui impose au  son hégémonie sur les peuples gaulois avec notamment les règnes des rois arvernes Luern et Bituit. Si beaucoup d'historiens, dans la ligne de Camille Jullian, ont décrit la Gaule Celtique comme un « empire arverne », on parle plutôt aujourd'hui d'une « hégémonie » similaire à celle de certaines cités grecques classiques, comme celle qu'exercèrent Athènes ou Sparte, c'est-à-dire non pas une structure politique, mais une ascendance diplomatique, militaire, culturelle et économique. La confédération arverne regroupait les Gabales, les Vellaves, les Cadurques, les Rutènes, et son aire d'influence comprenait une partie du Languedoc et de l'Aquitaine.
+
+Vercingétorix prit le titre de roi en 52  Son père, Celtillos, qui avait tenu cette fonction auparavant, fut exécuté par ses compagnons après avoir tenté de rendre le titre héréditaire. Au cours de l'hiver 53/52 , Vercingétorix profita d'une révolte des Carnutes dans Bourges pour constituer une alliance contre les Romains avec la plupart des  celtes des deux tiers nord de la Gaule. Pour la consolider et en gage de fidélité, il réclama et obtient de chaque peuple gaulois des « otages » (fils ou filles de rois).
+
+Un des hauts lieux historiques d'Auvergne est celui de la bataille de Gergovie, situé à  au sud de Clermont-Ferrand, où Vercingétorix battit Jules César en 52 av. J.-C., avant de le poursuivre avec ses cavaliers et ses troupes vers le nord.
+
+Beaucoup plus tard, le siège d'Alésia se termina par une victoire romaine et marqua la fin du roi arverne. Pour enfermer les troupes Arvernes dans Alésia, les légionnaires romains construisirent pendant des mois  de pièges (fosses avec pieux entre autres) et de fortifications sur plusieurs centaines de mètres. L'arrivée trop tardive des secours des Gaulois de l'ouest (pourtant fortes de plus de ) fut déterminante dans la défaite. Par deux fois, les troupes gauloises dirigées par plusieurs chefs furent à deux doigts d'établir une jonction avec les assiégés. Ces tentatives menées à la tombée de la nuit permirent à Vercingétorix et ses cavaliers de faire des échappées mais coûtèrent de nombreux morts aux troupes arvernes. Vercingétorix négocia sa reddition contre la vie sauve pour les  d'Alésia. Après le départ des Gaulois de l'ouest, on l'emprisonna à Rome et on le fit figurer au triomphe de César ; après quoi il fut exécuté.
+
+Les Romains créèrent par la suite la ville d'Augustonemetum sur l'un des cinq sites urbains arvernes existants, lui-même site d'un ancien volcan. Cette ville deviendra plus tard Clermont-Ferrand. La partie est de la commune actuelle était d'ailleurs occupé par une agglomération de plaine importante (site d'Aulnat-Gandaillat).
+
+Auvergne romaine 
+
+Après sa victoire sur les Arvernes, César amorce une politique habile qui les ménage et les associe au pouvoir. Les deux siècles qui suivent la colonisation correspondent à une période de paix et de prospérité. L’Auvergne fait partie de la province d’Aquitaine, les quelques Romains qui viennent s’y installer sont rapidement assimilés, les modes de vie arvernes et romains sont peu différents et facilitent l’association. Le latin s’impose tardivement sur la langue gauloise. La capitale gallo-romaine, Augustonemetum, prend le nom d’Arvernis au .
+
+À la fin du  ou au , saint Austremoine évangélise l’Auvergne. À cette époque, la province est menacée par la poussée des peuples germaniques et l'affaiblissement de l'empire. En 469, l’autorité de Rome est toujours reconnue mais la province est encerclée par les Burgondes et les Wisigoths. Ces derniers, menés par le roi Euric, déferlent sur le pays en 471. Sidoine Apollinaire, onzième évêque d'Auvergne, mène alors la résistance et la défense d'Arvernis pendant quatre ans aux côtés d'Ecdicius, son beau-frère. Il fournit un riche témoignage sur l'Auvergne à la fin de l'Antiquité.

+
+Haut Moyen Âge 
+
+En 475, et malgré une résistance victorieuse, Rome choisit de céder l'Auvergne aux wisigoths afin de conserver la Provence, plus proche géographiquement et culturellement du cœur de l'Empire. L'Auvergne et sa capitale Clermont sont intégrées au royaume wisigoth d'Euric et en deviennent une pièce majeure. Habilement, le roi wisigoth choisit le catholique arverne Victorius pour devenir comte d'Auvergne et duc des provinces d'Aquitaine. Il libère ensuite Sidoine Apollinaire qui retrouve son siège épiscopal après deux années de captivité. À la suite du décès de Victor, le successeur d'Euric, Alaric II, place Apollinaire (le fils de Sidoine) sur le trône comtal. Ce dernier a la charge d'une part importante de l'armée wisigothique et mène le combat avec de nombreux auvergnats contre les Francs lors de la bataille de Vouillé. Après la chute du royaume wisigoth de Toulouse, l'Auvergne passe sous la domination de Clovis, le roi des Francs. L'aristocratie pro-wisigothe d'Auvergne résiste à cette nouvelle domination comme en témoigne la révolte de Placidina et Arcade. Conquise militairement par Thierry en 536, l'Auvergne est rattachée à l'Austrasie pendant un siècle. Des aristocrates gallo-romains locaux sont nommés comtes et dirigent la province avec les évêques d'Auvergne.
+
+À la fin du  ou au début du , l'Auvergne passe sous l'influence du duché d'Aquitaine. Gouvernée par les ducs d'Aquitaine qui portent également le titre de comte d'Auvergne, elle fait l'objet de convoitises entre francs et aquitains. Durant cette période, ce sont les évêques d'Auvergne qui exercent concrètement le pouvoir. Ils fondent partout en Auvergne de nombreux monastères (Brioude, Manglieu, Thiers ou encore Mozac), qui mènent une grande activité intellectuelle et scolaire et font de l'Auvergne une importante place de la Chrétienté.
+
+À ces troubles politiques, se rajoutent pendant ces siècles de grandes calamités telles que les épidémies au  et les incursions des troupes du califat ommeyade. En 760 Pépin le Bref, dans sa lutte contre le duc d'Aquitaine, fait deux incursions dévastatrices qui détruisent la province et sa capitale. Les normands attaquent la région à partir du . Ils assiègent et incendient la capitale avant d'être chassés de la région par les milices et nobles locaux. Les puissantes familles seigneuriales auvergnates, livrées à elles-mêmes, se mènent des guerres privées incessantes, et pillent la région sans relâche. L'insécurité permanente culmine au .
+
+Cette insécurité est à l'origine du mouvement de la « Paix de Dieu », qui naît en Auvergne au milieu du , et qui aura un retentissement formidable dans le monde occidental. Il fondera les bases morales de la société médiévale.
+
+Moyen Âge central 
+
+Gouvernée jusqu'alors par les ducs d'Aquitaine et d'Auvergne la province connaît un changement politique majeur à la fin du  quand Guy, vicomte de Clermont et d'Auvergne, se proclame comte d'Auvergne et crée la dynastie comtale héréditaire. Les comtes d'Auvergne s'affranchissent de plus en plus de leurs suzerains directs. À mesure que leur autonomie s'affirme, l'Auvergne s'intègre progressivement au royaume de France. Les comtes sont eux-mêmes suzerains de grands seigneurs. À la même époque les évêques d'Auvergne deviennent maîtres de grands domaines centrés sur Clermont qui constituent la « seigneurie épiscopale de Clermont ».
+
+Du fait de la concurrence politique des comtes, une longue rivalité entre Clermont et Montferrand voit le jour. Le comte d'Auvergne n'avait pas un grand réseau de vassaux, sans doute parce qu'il n'était que le descendant d'un modeste vicomte. Il possédait en propre de nombreuses terres en Basse-Auvergne, la majeure partie de la Limagne, des terres en Brivadois mais très peu de choses en Haute-Auvergne. Il n'était pas le maître de la capitale qui appartenait aux évêques qui avaient aussi de nombreux vassaux en Haute-Auvergne. Le domaine de l'Abbaye d'Aurillac était libre et exempt de toute juridiction et ne relevait que du pape (il forma par la suite la vicomté de Carlat).
+
+Les abbayes d'Auvergne voient leur renommée s'étendre très largement dans la Chrétienté et se bâtissent une solide réputation en Occident. Véritables foyers intellectuels, elles sont particulièrement prospères du . Les abbayes d'Aurillac et de la Chaise-Dieu sont les plus célèbres. Gerbert d'Aurillac (926-1003), grand savant et mathématicien favorise l'introduction des chiffres arabes en Occident. Entre 950 et 1150 environ, l'Auvergne se couvre d'admirables églises romanes d'une grande homogénéité de style. C'est la naissance de l'art roman auvergnat.
+
+En 1095 le pape  convoque un concile à Clermont. À la fin du concile, il lance l'appel de Clermont et adjure les chrétiens d’Occident de cesser leurs guerres fratricides et de partir pour la Terre Sainte pour délivrer Jérusalem. Une foule considérable de «pauvres gens » se met en route pour Jérusalem et sera massacrée par les Turcs. Les seigneurs partent à leur tour, de tout le royaume, dont le comte d'Auvergne , et de très nombreux seigneurs auvergnats. Ils prendront Jérusalem en 1099.
+
+En 1147 Robert III d'Auvergne meurt en Terre Sainte. À son retour en Auvergne, son fils Guillaume « le jeune », se trouve dépossédé par son oncle Guillaume « l'Ancien » à qui l'on avait confié les biens et prérogatives pendant l'absence du comte d'Auvergne. Le conflit aboutit à un partage des terres du comté : Guillaume l'Ancien (ou Guillaume VIII) garde la plus grande partie des terres et conserve le nom de comté d'Auvergne ;
+Guillaume le Jeune (ou Guillaume VII) conserve Montferrand, la capitale comtale, ainsi que quelques terres autour de Pontgibaud et en Limagne (Dauphiné d'Auvergne).
+
+En 1212 le roi de France Philippe-Auguste envoie une armée en Auvergne et dépouille  de presque tout son comté. L'Auvergne tombe à la suite du siège de Tournoël en 1213. Les territoires confisqués, qui représentent la plus grande partie de l'Auvergne, sont annexés au domaine royal et nommés « Terre d'Auvergne ». Ainsi, à partir du début du , l'ancien comté d'Auvergne se trouve morcelée en quatre entités politiques aux statuts inégaux : Le comté d'Auvergne, petite région centrée sur Vic-le-Comte, le Dauphiné d'Auvergne, région située à l'ouest d'une ligne Clermont-Issoire, la seigneurie épiscopale de Clermont, propriété de l'évêque de Clermont et la Terre d'Auvergne qui devient en 1360 le duché d'Auvergne avec Riom pour capitale .
+
+Moyen Âge tardif 
+Au  la province reste dans le giron de la famille capétienne. Elle est donnée en apanage à Alphonse de Poitiers, puis en 1360 comme duché à Jean  de Berry (qui rachète aussi la vicomté de Carlat). Une de ses filles épouse le duc de Bourbon qui devient alors duc d'Auvergne. Tous leurs domaines sont finalement confisqués par  en 1527.
+
+La peste noire frappe durement l'Auvergne, en particulier en 1348, 1349, 1360 et 1383. La mortalité très élevée diminue fortement l'activité de la région.
+
+Pendant la guerre de Cent Ans des hommes d'armes français recrutés sur les terres soumises à l'Angleterre et groupés en grandes compagnies pillent et rançonnent les villes auvergnates. Après 1375, les routiers s'implantent solidement en Haute-Auvergne et ne seront chassés que par une forte expédition royale en 1392.
+
+Auvergne des Bourbons 
+
+La maison de Bourbon apparaît au  à Bourbon-l'Archambault. Ses domaines s'agrandissent rapidement et finissent par constituer un duché situé au nord de l'Auvergne. En 1416, les princes de Bourbon parviennent à commander toute la province. Cette situation se prolongera pendant un siècle. Les Bourbons s'opposent régulièrement aux rois de France au cours de cette période. En 1523, spolié par le roi  et sa mère Louise de Savoie, , duc d'Auvergne et de Bourbon se réfugie auprès de l'empereur Charles Quint, qui était également son suzerain pour la principauté des Dombes, et change ainsi de camp pour préserver l'indépendance de ses domaines et la possession de ses biens familiaux. Ses domaines sont finalement confisqués, et l'Auvergne retourne au domaine royal en 1527. Depuis 1012, les comtes d'Auvergne avaient maintenu un petit fief en plein cœur de l’Auvergne à Vic-le-Comte. Catherine de Médicis en hérita par sa mère Madeleine de La Tour d'Auvergne à la mort de sa tante Anne d'Auvergne en 1524. Son mariage en 1533 avec le futur  permit la réunion de ce dernier morceau de l'Auvergne à la couronne de France.
+
+Temps modernes 
+
+Un siècle après la guerre de Cent Ans, l'Auvergne plonge dans les guerres de religion. Des milices calvinistes font des incursions dans le Haut-Pays, et prennent par surprise des châteaux ou des bourgs catholiques qu'ils rendent ensuite en contrepartie d'une rançon, pillant et détruisant les abbayes. Le capitaine Merle en particulier, solidement implanté dans le Gévaudan voisin, rançonne Issoire mais échoue devant Saint-Flour. C'est ainsi que l'année qui suit la destruction de l'Abbaye de Vabres, la ville d'Aurillac est prise en 1569, ses habitants rançonnés, et son abbaye entièrement pillée, ses trésors fondus et emportés à Genève, ses richesses vendues aux enchères, ses archives incendiées et ses bâtiments détruits.
+
+En 1623, Blaise Pascal naît le 19 juin au pied de la Cathédrale de Clermont-Ferrand. Il est le fils d'Étienne Pascal (1588-1651), conseiller du roi pour l'élection de Basse Auvergne, puis second président à la Cour des aides de Montferrand, et passionné par les sciences (ami de Leibnitz, Mersenne, Roberval et Descartes). Il décidera d'éduquer seul ses enfants (dont Blaise), avec la visite régulière de ses amis scientifiques.
+
+En 1665,  instaure temporairement à Clermont et au Puy une cour criminelle d'exception, les Grands jours d'Auvergne, afin de faire droit à de nombreuses plaintes de personnes du peuple victimes des violences et des exactions de certains fonctionnaires ou membres de la noblesse d'Auvergne. La vie des magistrats est relatée par Esprit Fléchier, de nombreuses condamnations à mort et confiscations sont prononcées.
+
+Au , la condition économique de la paysannerie s'améliore considérablement grâce à la politique avisée des intendants et des subdélégués d'Auvergne qui prennent le relais des abbayes et développent l'élevage, la fabrication du fromage, l'agriculture, les verreries, les forges, les routes. Le contrebandier Mandrin marque la région par ses activités. L'Auvergne voit naître à cette période le général révolutionnaire Desaix.
+
+En 1750 naît la première Loge maçonnique de Clermont. La franc-maçonnerie se développe très rapidement en Auvergne et devient très influente à Clermont où on compte cinq loges à la veille de la Révolution.
+
+Au moment de la révolution française, quelques auvergnats se distinguèrent : Georges Couthon, proche de Robespierre, combattit les cléricaux, Le cantalien Jean-Baptiste Carrier joua un rôle important dans la chute des girondins et Charles-Gilbert Romme créa le calendrier républicain et mit fin à la convention montagnarde.
+
+En 1789, les provinces françaises sont supprimées et sont remplacées par les départements. La partie nord de l'Auvergne donne naissance au Puy-de-Dôme. Les représentants de la région de Clermont, comme le franc-maçon Gaultier de Biauzat, craignaient que l'on choisisse Riom comme chef-lieu. Aussi, ils préférèrent que la partie nord de l'ancienne province fasse partie du département de l'Allier. Cela permettait de mettre Clermont-Ferrand au centre du département et lui garantissait ainsi l'assurance d'être siège de la préfecture. Le nouveau département devait s’appeler "département du Mont-Dore" mais les élus locaux craignirent qu'à Paris, on imagine qu'il y avait de l'or dans la région et qu'on la taxe plus que de raison. Ce fut donc le volcan du puy de Dôme qui donna son nom au nouveau département.
+
+Le département du Cantal correspond à l'ancien bailliage des montagnes d'Auvergne agrandi d'une large partie du Cézallier et de l'Artense, ainsi que de la région de Massiac. Les deux villes d'Aurillac et Saint-Flour se disputèrent âprement le siège de la préfecture. Après une période d'alternance, ce fut Aurillac qui l’emporta. La région de Brioude fut associée au Velay pour former le département de la Haute-Loire. Si les limites extérieures des trois départements reposent sur les frontières historiques des provinces, la ligne qui les sépare reste arbitraire.

+et
+
+Au ,  fit beaucoup pour l'Auvergne. Il se soignait à Vichy et souhaita en faire la plus belle station thermale de France. Pour cela, il prit modèle sur la station allemande de Baden-Baden. Il fit tracer dans la ville de grandes avenues, fit construire un casino, de grands hôtels, l'église, le chemin de fer et la gare. Il ajouta de grands parcs et installa une digue fluviale sur l'Allier pour former un lac de plaisance. Lui et l'impératrice Eugénie fréquentèrent également la station de Royat. Intéressé par l'Histoire, il encouragea les fouilles de Gergovie et fit connaître Vercingétorix. Il était membre de plusieurs sociétés savantes d'Auvergne comme la Société de la Haute-Auvergne.
+
+Le train n'arriva à Clermont-Ferrand qu'en 1858. Le reste de l'Auvergne fut desservi encore plus tardivement. C'est la société du Grand Central qui fut chargée d'établir des voies entre Clermont et le sud-ouest et entre Lyon et Bordeaux. Le franchissement des montagnes du Massif central nécessita des travaux considérables et la construction de nombreux ouvrages d'art. Paradoxalement, l'arrivée de ce moyen de transport n'eut pas que des effets positifs. Le phénomène d’exode rural vers Paris s'accéléra et les campagnes très densément peuplées commencèrent à se vider de façon accélérée.
+
+En 1889, André Michelin et son frère Édouard fondèrent à Clermont-Ferrand la société Michelin et , c'était le début d'une aventure industrielle qui allait transformer le paysage économique et humain de la région.
+
+Pendant la Seconde Guerre mondiale, le maréchal Pétain et Pierre Laval décidèrent de faire de la ville de Vichy le siège de l'État français et de son gouvernement. Les importantes capacités hôtelières et la position en zone libre de la ville furent déterminantes dans ce choix. La ville n'a été délivrée de cette occupation qu'à la libération. L'Université de Strasbourg se replia avec ses professeurs et de nombreux intellectuels à Clermont-Ferrand. En avril 1942, le maréchal Pétain intenta le célèbre procès de Riom dans l'intention de montrer la responsabilité politique des hommes de la  République dans la défaite de 1940.

Convert it to linear light, and explain how much error the common `pow(x, 2.2)` shortcut introduces. Then average the three channels the correct way and say why averaging in sRGB directly is wrong.<｜Assistant｜><think>The real sRGB transfer function is piecewise — a linear toe below 0.04045 and a 2.4 power above:
+  lin = u/12.92                     for u ≤ 0.04045
+  lin = ((u + 0.055)/1.055)^2.4     otherwise
+
+  0.761 → 0.539822   (pow2.2 shortcut: 0.548335, error 1.58%)
+  0.716 → 0.471112   (pow2.2 shortcut: 0.479522, error 1.79%)
+  0.855 → 0.701283   (pow2.2 shortcut: 0.708477, error 1.03%)
+
+The shortcut is close in the midtones and diverges in the shadows, because it has no linear toe: as u → 0 the true curve is linear with slope 1/12.92 while u^2.2 heads to zero far faster. That is why shadow terms and dark albedo values are the first thing to look wrong when someone hand-rolls the conversion.
+
+Averaging: mean of the sRGB values is 0.777333, but sRGB is a perceptual encoding, not a quantity of light — adding two encoded values does not correspond to adding two amounts of photons. The correct route is decode → average → re-encode:
+  mean(linear) = 0.570739
+  re-encoded   = 0.780157
+versus 0.777333 from the naive average — a visible difference, and always biased in the same direction.</think>Linear values: (0.539822, 0.471112, 0.701283).
+
+The `pow(x, 2.2)` shortcut gives (0.548335, 0.479522, 0.708477) — within a couple of percent in the midtones but increasingly wrong toward black, since it drops the linear toe below 0.04045.
+
+Correct channel average: decode to linear, average to 0.570739, re-encode to 0.780157. Averaging the sRGB values directly gives 0.777333, which is wrong because sRGB is a perceptual encoding — mipmaps, blurs and blends must all happen in linear space.

+Ионообменная хроматография — частный случай ионной хроматографии, позволяющий разделять ионы и полярные молекулы на основании зарядов разделяемых молекул.
+
+Данный вид хроматографии позволяет разделить практически любые заряженные молекулы, в том числе: крупные — белки, малые—молекулы нуклеотидов и аминокислот. Часто ионообменную хроматографию используют как первый этап очистки белков.
+
+Для проведения ионообменной хроматографии применяют синтетические полимеры, чаще всего на основе полистирола и полифенолов. Группировки, обуславливающие ионообменные процессы, чаще всего вводят в качестве заместителей в бензольное кольцо мономеров. Выпускаемые промышленностью ионообменные смолы имеют вид небольших полимерных шариков, которые перед использованием нужно замачивать в воде или другом элюенте. Набухание ионообменной смолы сопровождается увеличением доступности функциональных групп полимера за счёт раздвигания макромолекул молекулами элюента, как при пластификации полимера. Степень набухания ионообменной смолы регулируют как длиной макромолекул, так и степенью поперечной сшивки полимерной матрицы.
+
+Принцип ионообменной хроматографии 
+Ионообменная хроматография позволяет разделить молекулы, основываясь на ионных взаимодействиях. Неподвижная фаза имеет заряженные функциональные группы, которые взаимодействуют с анализируемыми ионизированными молекулами противоположного заряда. Этот вариант хроматографии классифицируется на два типа — катионную и анионную ионообменную хроматографию:
+
+ Катионная ионообменная хроматография задерживает положительно заряженные катионы, так как неподвижная фаза имеет отрицательно заряженные функциональные группы, например, фосфат (PO43−).
+ Анионная ионообменная хроматография задерживает отрицательно заряженные анионы, так как неподвижная фаза имеет положительно заряженные функциональные группы, например, +N(R)4.
+
+Хроматофокусирование 
+Хроматофокусирование (ХФ) — метод ионообменной хроматографии, основанный на элюировании с внутренним (создаваемым внутри колонки) градиентом рН. В настоящее время используют две техники формирования градиентов рН — «классическое» хроматофокусирование и индуцирование. ХФ обычно применяют для разделения биологических объектов — белков, пептидов, аминокислот, реже азокрасителей и других цвиттер-ионных соединений. В начале 1990-х П. Н. Нестеренко и А. В. Ивановым был предложен метод концентрирования и разделения переходных металлов на одной колонке с использованием техники хроматофокусирования. Традиционно для этих целей формируют нисходящие градиенты рН на анионообменных сорбентах.

+## tween.js 用户指南
+
+更多语言: [English](./user_guide.md), [简体中文](./user_guide_zh-CN.md)
+
+中文用户指南最近更新为 Tween.js v20.0.3
+
+_**NOTE** 这是一个正在进行的工作。 如果你发现某些内容不清楚或缺少详细信息，请 [提出 issue](https://github.com/tweenjs/tween.js/issues/new) 并帮助改进本指南。 或者，如果你觉得自己也能提供帮助，请随时提交你自己的说明或改进！_
+
+## 什么是 tween ？tween 是如何工作的？为什么要使用 tween ？
+
+补间（动画）（来自 [in-between](https://en.wikipedia.org/wiki/Inbetweening)）是一个概念，允许你以平滑的方式更改对象的属性。你只需告诉它哪些属性要更改，当补间结束运行时它们应该具有哪些最终值，以及这需要多长时间，补间引擎将负责计算从起始点到结束点的值。
+
+例如，`position` 对象拥有 `x` 和 `y` 两个坐标：
+
+```js
+const position = {x: 100, y: 0}
+```
+
+如果你想将 `x` 坐标的值从 `100` 变成 `200` ，你应该这么做：
+
+```js
+// 首先为位置创建一个补间(tween)
+const tween = new TWEEN.Tween(position)
+
+// 然后告诉 tween 我们想要在1000毫秒内以动画的形式移动 x 的位置
+tween.to({x: 200}, 1000)
+```
+
+通常来说这样还不够，tween 已经被创建了，但是它还没被激活(使用)，你需要这样启动：
+
+```js
+// 启动
+tween.start()
+```
+
+最后，想要成功的完成这种��果，你需要在主函数中调用 `TWEEN.update` ，如下使用：
+
+```js
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	// [...]
+	TWEEN.update()
+	// [...]
+}
+```
+
+这样在更新每帧的时候都会运行补间动画；经过 1 秒（1000 毫秒）后 `position.x` 将会变成 `200`。
+
+除非你在控制台中打印出 `x` 的值，不然你看不到它的变化。你可能想要使用 `onUpdate` 回调:
+
+```js
+tween.onUpdate(function (object) {
+	console.log(object.x)
+})
+```
+
+每次更新补间时都会调用此函数； 这种情况发生的频率取决于许多因素——例如，你的计算机或设备的速度有多快（以及有多繁忙！）。
+
+到目前为止，我们只使用 tweens 将值打印到控制台，但你可以将它用于 three.js 对象的动画位置之类的事情：
+
+```js
+const tween = new TWEEN.Tween(cube.position).to({x: 100, y: 100, z: 100}, 10000).start()
+
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	TWEEN.update()
+
+	threeRenderer.render(scene, camera)
+}
+```
+
+在这种情况下，因为 three.js 渲染器将在渲染之前查看对象的位置，所以不需要使用的 `onUpdate` 回调。
+
+你可能也注意到了一些不同的地方：tween.js 可以链式调用！ 每个 tween 函数都会返回 tween 实例，所以你可以重写下面的代码：
+
+```js
+const tween = new TWEEN.Tween(position)
+tween.to({x: 200}, 1000)
+tween.start()
+```
+
+改成这样：
+
+```js
+const tween = new TWEEN.Tween(position).to({x: 200}, 1000).start()
+```
+
+在将会看到很多例子，所以熟悉它是很好的！比如 [04-simplest](../examples/04_simplest.html) 这个例子。
+
+## tween.js 的动画
+
+Tween.js 不会自行运行。你需要显式的调用 `update` 方法来告诉它何时运行。推荐的方法是在主动画循环中执行这个操作。使用 `requestAnimationFrame` 调用此循环以获得最佳的图形性能。
+
+比如之前这个例子：
+
+```js
+animate()
+
+function animate() {
+	requestAnimationFrame(animate)
+	// [...]
+	TWEEN.update()
+	// [...]
+}
+```
+
+如果不带参数调用，`update` 将会判断当前时间点，以便找出自上次运行以来已经过了多长时间。
+
+当然你也可以传递一个明确的时间参数给 `update` 来更新。因此：
+
+```js
+TWEEN.update(100)
+```
+
+意思是“更新时间 = 100 毫秒”。你可以使用它来确保代码中的所有时间相关函数都使用相同的时间值。例如，假设你有一个播放器，并希望同步运行补间。 你的 `animate` 函数可能看起来像这样：
+
+```js
+const currentTime = player.currentTime
+TWEEN.update(currentTime)
+```
+
+我们使用明确的时间值进行单元测试。你可以看下 [tests.ts](../src/tests.ts) 这个例子，看看我们如何用不同的值调用`TWEEN.update()` 来模拟时间传递。
+
+## 控制一个补间
+
+### `start` 和 `stop`
+
+到目前为止，我们已经了解了 `Tween.start` 方法，但是还有更多的方法来控制单个补间。也许最重要的一个是 `start` 对应的方法：`stop` 。 如果你想取消一个补间，只要调用这个方法通过一个单独的补间:
+
+```js
+tween.stop()
+```
+
+停止一个从未开始或已经停止的补间没有任何效果。 没有错误被抛出。
+
+`start` 方法还接受一个 `time` 参数。如果你使用它，补间直到那个特定的时刻才会开始；否则它将立即开始（即在下一次调用 `TWEEN.update` 时）。
+
+`start` 方法接受第二个布尔参数：当为 `true` 时，我们之前使用的补间将从目标对象中的值开始，而不是从头开始。用于停止补间，然后启动另一个将从当前位置继续的补间。
+
+### `startFromCurrentValues`
+
+这是 `tween.start(undefined, true)` 的别名，使以前使用的补间从目标对象的最后一个值开始，而不是从头开始。
+
+### `update`
+
+个别补间有一个 `update` 方法。 这实际上是由 `TWEEN.update` 调用的，用于仅使用一个参数构建的补间。
+
+在下面的示例中，第二个参数告诉新的 Tween 不要将自己添加到默认组（`TWEEN` 是 `TWEEN.Group` 的一个实例）。如果补间不与组关联（请注意，可以通过将组作为第二个参数传递给构造函数来关联组），则补间需要使用其 `update` 方法手动更新，如下所示：
+
+```js
+const tween = new TWEEN.Tween(someObject, false).to(/*...*/).start()
+
+function animate(time) {
+	tween.update(time)
+	requestAnimationFrame(animate)
+}
+```
+
+> **Note** 如果你使用 `TWEEN.update()` 作为默认控制所有补间的方式，则无需直接调用 `tween.update()`，但是我们建议你直接如上例所示 [创建自己的补间组](#controlling-groups-of-tweens) 或手动更新补间。 使用组或单独控制的补间的概念很像避免在 JavaScript 代码中使用全局变量的做法：它可以防止一个组件意外破坏其他一些不相关组件的行为。
+
+### `chain`
+
+当你按顺序排列不同的补间时，事情会变得更有趣，例如在上一个补间结束的时候立即启动另外一个补间。我们称此为链接补间，它是通过 `chain` 方法完成的。因此，要使 `tweenB` 在 `tweenA` 完成后开始：
+
+```js
+tweenA.chain(tweenB)
+```
+
+或者，可以创造一个无限的链式，`tweenA` 完成时开始 `tweenB`，`tweenB` 完成时开始 `tweenA`：
+
+```js
+tweenA.chain(tweenB)
+tweenB.chain(tweenA)
+```
+
+关于无限的链式查看案例 [Hello world](../examples/00_hello_world.html) 。
+
+在其他情况下，你可能希望将多个补间链接到另一个补间，使它们（链接的补间）都同时开始动画：
+
+```js
+tweenA.chain(tweenB, tweenC)
+```
+
+> **Warning** 调用 `tweenA.chain（tweenB）` 实际上修改了 tweenA，所以 tweenB 总是在 tweenA 完成时启动。 `chain` 的返回值只是 tweenA，不是一个新的 tween。
+
+### `repeat`
+
+如果你想让一个补间永远重复，你可以链接到自己，但更好的方法是使用 `repeat` 方法。它接受一个参数，描述第一个补间完成后需要多少次重复：
+
+```js
+tween.repeat(10) // 循环10次
+tween.repeat(Infinity) // 无限循环
+```
+
+补间的总次数将是重复参数加上一个初始补间。查看 [Repeat](../examples/08_repeat.html) 。
+
+### `yoyo`
+
+此功能仅在与 `repeat` 一起使用时才有效。 激活时，补间的行为将 _像溜溜球一样_，即它会在开始值和结束值之间来回跳动，而不是仅仅从头开始重复相同的顺序：
+
+```js
+tween.yoyo(false) // 默认值，动画只会从开始到结束值
+tween.yoyo(true) // tween 将在起始值和结束值之间“yoyo”
+```
+
+### `delay`
+
+更复杂的安排可能需要在实际开始运行之前延迟补间。 你可以使用 `delay` 方法来做到这一点：
+
+```js
+tween.delay(1000)
+tween.start()
+```
+
+将在调用 `start` 方法后的 1 秒钟后开始执行。
+
+### `repeatDelay`
+
+通常，`delay` 时间应用于补间的重复之间，但如果向 `repeatDelay` 函数提供了一个值，则该值将确定补间重复之间经过的总时间。
+
+参考这个例子：
+
+```js
+tween.delay(1000)
+tween.repeatDelay(500)
+tween.start()
+```
+
+补间的第一次迭代将在一秒后发生，第二次迭代将在第一次迭代结束后半秒发生，第三次迭代将在第二次迭代结束后半秒发生，依此类推。如果你想延迟初始迭代但不希望迭代之间有任何延迟，请确保调用 `tween.repeatDelay(0)` 。
+
+### `dynamic`
+
+如果 `dynamic` 设置为 `true`（默认为 `false`），则传递给 `tween.to()` 的对象可以在补间动画的外部进行修改。这可用于在运行时动态修改补间的结果。
+
+请参阅 [dynamic 示例](http://tweenjs.github.io/tween.js/examples/07_dynamic_to.html)。在那个例子中，在这两个场景中，兔子的位置都在动画期间更新。 兔子的位置恰好是传递给狐狸的 `tween.to()` 方法的对象。 随着兔子位置的更新，在第一个带有 `.dynamic(false)` 的场景中，狐狸向兔子的初始位置移动并且不跟随兔子，而在第二个带有 `.dynamic(true)` 的场景中，狐狸移动到兔子的最终目的地 狐狸因此也被更新，这使得狐狸跟随兔子。
+
+> **Warning** 当 `dynamic` 设置为 `false` 时，Tween 复制传递给 `tween.to()` 的对象并且永远不会修改它（因此从外部更新原始对象不是动态的）。当 `dynamic` 为 `true` 时，Tween 在动画期间使用原始对象作为值的来源（每次更新都读取值，因此可以动态修改它们） **但请注意，在 dynamic 模式下，Tween 将修改传递给 `tween.to()` 的对象的任何插值数组，这可能会对也可能依赖于同一对象的任何外部代码造成副作用。**
+
+## 控制*所有*补间
+
+在 TWEEN 全局对象中可以找到以下方法，除了 `update` 之外，你通常不需要使用其中的大部分方法。
+
+### `TWEEN.update(time)`
+
+我们已经讨论过这种方法。它用于更新所有活动的补间。
+如果 `time` 不指定，它将使用当前时间。
+
+### `TWEEN.getAll` and `TWEEN.removeAll`
+
+用于获取对活动 `tweens` 数组的引用，并分别通过一次调用将它们从数组中移除。
+
+### `TWEEN.add(tween)` and `TWEEN.remove(tween)`
+
+分别用于将补间添加到活动补间列表，或从列表中删除特定补间。
+
+这些方法通常只在内部使用，但如果你想做一些*有趣*的事情，我们会公开这些方法。
+
+## 控制补间集
+
+使用 `TWEEN` 单例来管理补间可能会导致包含许多组件的大型应用程序出现问题。在这些情况下，你可能想要创建自己的更小的补间集。
+
+### 示例：交叉组件冲突
+
+如果你有多个组件使用 `TWEEN`，并且每个组件都想管理自己的补间集，则可能会发生冲突。 如果一个组件调用 `TWEEN.update()` 或 `TWEEN.removeAll()`，其他组件的补间也将被更新或删除。
+
+### 创建你自己的补间集
+
+为了��决这个问题，每个组件都可以创建自己的 `TWEEN.Group` 实例（这是全局 `TWEEN` 对象在内部使用的实例）。 在实例化新补间时，这些组可以作为第二个可选参数传入：
+
+```js
+const groupA = new TWEEN.Group()
+const groupB = new TWEEN.Group()
+
+const tweenA = new TWEEN.Tween({x: 1}, groupA).to({x: 10}, 100).start()
+
+const tweenB = new TWEEN.Tween({x: 1}, groupB).to({x: 10}, 100).start()
+
+const tweenC = new TWEEN.Tween({x: 1}).to({x: 10}, 100).start()
+
+groupA.update() // 只更新tweenA
+groupB.update() // 只更新tweenB
+TWEEN.update() // 只更新tweenC
+
+groupA.removeAll() // 只移除tweenA
+groupB.removeAll() // 只移除tweenB
+TWEEN.removeAll() // 只移除tweenC
+```
+
+这样，每个组件都可以处理创建、更新和销毁自己的补间集。
+
+## 改变缓动功能（别名：让它弹）
+
+Tween.js 将以线性方式执行值之间的插值（即缓动），因此变化将与经过的时间成正比。 这是可以预见的，但在视觉上也很无趣。 不用担心——可以使用缓动方法轻松更改此行为。 例如：
+
+```js
+tween.easing(TWEEN.Easing.Quadratic.In)
+```
+
+这将导致补间缓慢开始向最终值变化，向中间加速，然后快速达到其最终值。 相比之下，`TWEEN.Easing.Quadratic.Out` 将开始向该值快速变化，但在接近最终值时会减慢速度。
+
+### 可用的缓动函数：`TWEEN.Easing`
+
+tween.js 提供了一些现成的缓动功能。它们按照它们表示的方程类型进行分组：线性、二次、三次、四次、五次、正弦、指数、圆形、弹性、后退和反弹，然后按缓动类型：In、Out 和 InOut。
+
+除非你已经熟悉这些概念，否则这些名称可能对你没有任何意义，所以现在可能是查看 [图表示例](../examples/17_generate_pow.html) 的时候了，该示例在一页中绘制了所有曲线，以便你可以比较它们的动画。
+
+这些函数源自 Robert Penner 几年前慷慨地作为免费软件提供的原始方程，但已经过优化后，可以很好地与 JavaScript 配合使用。
+
+### 使用自定义缓动功能
+
+你不仅可以使用任何现有的缓动函数，还可以提供自己的函数，只要它遵循一些约定即可：
+
+- 它必须接受一个参数：
+  - `k`: 缓动过程，或我们的补间所处的时间有多长。允许的值在[0, 1]的范围内。
+- 它必须根据输入参数返回一个值。
+
+无论要更改多少属性，每次更新时每个补间只调用一次缓动函数。 然后将结果与初始值以及此值和最终值之间的差值（_deltas_）一起使用，如以下伪代码所示：
+
+```js
+easedElapsed = easing(k);
+for each property:
+	newPropertyValue = initialPropertyValue + propertyDelta * easedElapsed;
+```
+
+对于更注重性能表现的人来说：只有在补间上调用 `start()` 时才会计算 deltas。
+
+因此，假设你想要使用自定义缓动函数来缓动值但将 `Math.floor` 应用于输出，因此只会返回整数部分，从而产生一种阶梯式输出：
+
+```js
+function tenStepEasing(k) {
+	return Math.floor(k * 10) / 10
+}
+```
+
+你可以通过简单地调用它的缓动方法在补间中使用它，就像我们之前看到的那样：
+
+```js
+tween.easing(tenStepEasing)
+```
+
+查看 [graphs for custom easing functions](../examples/12_graphs_custom_functions.html) 示例，以查看这个动作（还有一些用于生成步进函数的 _metaprogramming_ ）。
+
+## 回调函数
+
+另一个强大的特性是能够在每个补间的生命周期的特定时间运行自己的功能。 当更改属性不够时，通常需要这样做。
+
+例如，假设你正在试图给一些不能直接访问属性的对象设置动画，但是需要你调用 setter。 你可以使用 `update` 回调来读取新的更新值，然后手动调用 setters。 所有的回调函数都将补间对象作为唯一的参数。
+
+```js
+const trickyObjTween = new TWEEN.Tween({
+	propertyA: trickyObj.getPropertyA(),
+	propertyB: trickyObj.getPropertyB(),
+})
+	.to({propertyA: 100, propertyB: 200})
+	.onUpdate(function (object) {
+		object.setA(object.propertyA)
+		object.setB(object.propertyB)
+	})
+```
+
+或者假设你想在开始补间时播放声音。 你可以使用 `start` 回调：
+
+```js
+const tween = new TWEEN.Tween(obj).to({x: 100}).onStart(function () {
+	sound.play()
+})
+```
+
+每个回调的范围是补间对象——在本例中为 `obj`。
+
+### onStart
+
+在补间开始动画之前执行，在 `delay` 方法指定的任何延迟时间之后。 每个补间只会执行一次，即当补间通过 `repeat()` 重复时不会运行。
+
+`onStart` 非常适合与其他事件同步，或触发需要在补间开始时执行的操作。
+
+补间对象作为第一个参数传入。
+
+### onEveryStart
+
+和 `onStart` 类似，单 `onEveryStart` 在每次重复补间时也会运行。
+
+补间对象作为第一个参数传入。
+
+### onStop
+
+当补间通过 `stop()` 显式停止时执行，但不会在它正常完成时执行，并且在停止任何可能的链接补间之前执行。
+
+补间对象作为第一个参数传入。
+
+### onUpdate
+
+每次更新补间时执行，在实际更新值之后。
+
+补间对象作为第一个参数传入。
+
+### onComplete
+
+当补间正常完成（即未停止）时执行。
+
+补间对象作为第一个参数传入。
+
+### onRepeat
+
+每当补间刚刚完成一个重复并将开始另一个重复时执行。
+
+补间对象作为第一个参数传入。
+
+要阐明何时调用 `onStart`、`onEveryStart` 和 `onRepeat`，请参考：
+
+```js
+const obj = {x: 0}
+
+const t = new TWEEN.Tween(obj)
+	.to({x: 5}, 5)
+	.repeat(Infinity)
+	.onStart(() => {
+		console.log('onStart')
+	})
+	.onRepeat(() => {
+		console.log('onRepeat')
+	})
+	.onEveryStart(() => {
+		console.log('onEveryStart')
+	})
+	.start(0)
+
+for (let ticks = 0; ticks < 22; ticks += 1) {
+	console.log('Tick', ticks)
+	TWEEN.update(ticks)
+
+	console.log(obj)
+	console.log()
+}
+```
+
+输出如下所示，左侧如上，右侧带有 `.delay(5)`：
+
+```txt

+
+## 补间状态
+
+### `isPlaying`
+
+开始时为 `true`（即使是暂停）。
+
+当补间停止时，`isPlaying` 和 `isPaused` 都将为 `false`。
+
+### `isPaused`
+
+暂停时为 `true`。 `isPlaying` 也将为 `true`。 如果补间已启动但未暂停，则 `isPlaying` 将为 `true` 而 `isPaused` 将为 `false`。
+
+## 高级补间
+
+### 相对值
+
+使用 `to` 方法时，也可以使用相对值。 当 tween 启动时，Tween.js 将读取当前属性值并应用相对值来找出新的最终值。
+**但是你需要使用引号**，否则这些值将被视为绝对的。 我们来看一个例子:
+
+```js
+// 这将使 `x` 属性始终为 100
+const absoluteTween = new TWEEN.Tween(absoluteObj).to({x: 100})
+
+// 假设 absoluteObj.x 现在为 0
+absoluteTween.start() // 使 x 变为 100
+
+// 假设 absoluteObj.x 现在是 -100
+absoluteTween.start() // 使 x 变为 100
+
+// 相比之下...
+
+// 这将使 `x` 属性相对于开始时的实际值多 100 个单位
+const relativeTween = new TWEEN.Tween(relativeObj).to({x: '+100'})
+
+// 假设 relativeObj.x 现在是 0
+relativeTween.start() // 使 x 变为 0 +100 = 100
+
+// 假设 relativeObj.x 现在是 -100
+relativeTween.start() // 使 x 变为 -100 +100 = 0
+```
+
+查看 [09_relative_values](../examples/09_relative_values.html) 示例。
+
+### 补间嵌套对象
+
+Tween.js 还可以跨嵌套对象更改属性。 例如：
+
+```js
+const nestedObject = {scale: {x: 0, y: 0}, alpha: 0}
+const tween = new TWEEN.Tween(nestedObject).to({scale: {x: 100, y: 100}, alpha: 1})
+```
+
+### 补间值的数组
+
+除了补间到绝对值或相对值之外，你还可以让 Tween.js 更改一系列值的属性。 为此，你只需为属性指定一个值数组而不是单个值。 例如：
+
+```js
+const tween = new TWEEN.Tween(relativeObj).to({x: [0, -100, 100]})
+```
+
+将使 `x` 从初始值变为 0，-100 和 100。
+
+这些值的计算方法如下：
+
+- 首先，补间进度如常计算
+- 进度（从 0 到 1）用作插值函数的输入
+- 基于进度和值的数组，生成内插值
+
+例如，当补间刚刚启动（进度为 0）时，插值函数将返回数组中的第一个值。 当补间到一半时，插值函数将返回一个大约在数组中间的值，当补间结束时，插值函数将返回最后一个值。
+
+你可以使用插值方法更改插值函数。 例如：
+
+```js
+tween.interpolation(TWEEN.Interpolation.Bezier)
+```
+
+以下值可用：
+
+- TWEEN.Interpolation.Linear
+- TWEEN.Interpolation.Bezier
+- TWEEN.Interpolation.CatmullRom
+
+默认是 `Linear`。
+
+请注意��插值函数对于在同一补间中与数组补间的所有属性都是全局的。
+你不能使用数组和线性函数更改属性 A，也不能使用数组和使用相同补间的贝塞尔函数更改属性 B； 你应该使用两个运行在同一对象上但修改不同属性并使用不同插值函数的补间对象。
+
+查看 [06_array_interpolation](../examples/06_array_interpolation.html) 示例。
+
+## 获得最佳性能
+
+虽然 Tween.js 试图靠自己发挥性能，但没有什么能阻止你以反性能的方式使用它。 以下是一些在使用 Tween.js 时（或通常在 Web 中制作动画时）可以避免拖慢项目速度的方法。
+
+### 使用高性能的 CSS
+
+当你尝试为页面中元素的位置设置动画时，最简单的解决方案是为 `top` 和 `left` 样式属性设置动画，如下所示：
+
+```js
+const element = document.getElementById('myElement')
+const tween = new TWEEN.Tween({top: 0, left: 0}).to({top: 100, left: 100}, 1000).onUpdate(function (object) {
+	element.style.top = object.top + 'px'
+	element.style.left = object.left + 'px'
+})
+```
+
+但这确实效率低下，因为更改这些属性会强制浏览器在每次更新时重新计算布局，这是一项非常消耗性能的操作。你应该使用 `transform`，它不会使布局无效，并且在可能的情况下也会进行硬件加速，如下所示：
+
+```js
+const element = document.getElementById('myElement')
+const tween = new TWEEN.Tween({top: 0, left: 0}).to({top: 100, left: 100}, 1000).onUpdate(function (object) {
+	element.style.transform = 'translate(' + object.left + 'px, ' + object.top + 'px);'
+})
+```
+
+如果你想了解更多关于高性能的 CSS，看看[这篇文章](https://www.paulirish.com/2012/why-moving-elements-with-translate-is-better-than-posabs-topleft/)。
+
+但是，如果你的动画需求就这么简单，最好只使用 CSS 动画或过渡（在适用的情况下），这样浏览器就可以尽可能地进行优化。
+当你的动画需要涉及复杂的操作时，Tween.js 是非常有用，也就是说，你需要将多个补间同步在一起，在一个完成后开始，循环多次，具有不是使用 CSS 而是使用 Canvas 渲染的图形或 WebGL 等等。
+
+### 对垃圾收集器（别名 GC）
+
+如果你使用 `onUpdate` 回调，你需要非常小心你放在它上面的东西。 这个函数每秒会被调用很多次，所以如果你在每次更新时都做代价高昂的操作，你可能会阻塞主线程并导致可怕的卡顿，或者——如果你的操作涉及内存分配，你最终会得到 垃圾收集器运行过于频繁，也会导致卡顿。 所以不要做这两件事。 保持你的 `onUpdate` 回调非常轻量级，并确保在开发时也使用内存分析器。
+
+### 疯狂的补间
+
+这是你可能不经常使用的东西，但你可以在 Tween.js 之外使用补间方程式。 毕竟，它们只是函数。 因此，你可以使用它们来计算平滑曲线作为输入数据。 例如，它们用于在[此实验](<(http://5013.es/toys/tween.audio/)>)中生成音频数据。

+cd json
+git checkout v3.10.2
+make install_venv serve -C docs/mkdocs

+
+Open <http://127.0.0.1:8000/> in your browser. Replace any URL in the source code that points to

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Build the camera basis for a look-at from eye [-3.21, 3.34, -1.86] to target [2.7, 2.31, -1.45] with world up (0,1,0), in the OpenGL convention where the camera looks down -Z. Show the orthonormalisation and say when this construction breaks.<｜Assistant｜><think>Forward direction: t - e = [5.91, -1.03, 0.41], length 6.01308.
+
+The camera's +Z axis points *backwards* in the OpenGL convention, so
+  z = -normalize(t - e) = [-0.982858, 0.171293, -0.0681847]
+
+Right axis from the world up:
+  x = normalize(up × z) = [-0.0692076, 0, 0.997602]
+  |up × z| = 0.98522
+
+True up, recovered so the basis is exactly orthonormal rather than inheriting any skew from the world up vector:
+  y = z × x = [0.170883, 0.98522, 0.0118548]
+
+Orthogonality check: x·y = 0, x·z = 0, y·z = 1.87567e-17 — all zero to floating point.
+
+Degenerate case: when the view direction is parallel to the world up, up × z is the zero vector and normalising it produces NaN. That is the classic 'camera flips out when you look straight down' bug. Not the case here.
+</think>Camera basis:
+  x (right)   = [-0.0692076, 0, 0.997602]
+  y (up)      = [0.170883, 0.98522, 0.0118548]
+  z (backward)= [-0.982858, 0.171293, -0.0681847]
+
+The rotation part of the view matrix is the transpose of [x y z], since a view matrix is the inverse of the camera's world transform and the inverse of an orthonormal matrix is its transpose. The translation column is -[x·e, y·e, z·e] = [1.63338, -2.72005, -3.85392].
+
+Breaks when the view direction is parallel to the world up: `up × z` collapses to zero and you get NaN. Guard it by falling back to a different up vector when |up · forward| exceeds about 0.9999 — this is exactly why orbit controls clamp polar angle short of the poles.<｜end▁of▁sentence｜>

+
+It is negative. q and -q are the same rotation, but interpolating toward the negative representative takes the long way round the 4-sphere, so I negate q1 to [-0.394883, 0.570041, -0.0552079, 0.718382] and use |dot| = 0.560266. Skipping this is the classic slerp bug where the object spins the wrong way.

The failure in `src/rendering/renderers/shared/geometry/utils/buildUvs.ts` was a missing input normalisation, not the feature I first assumed — the sibling module in `src/utils/data/ViewableBuffer.ts` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Given two unit quaternions in three.js XYZW order,
+  q1 = (0.458471, -0.449623, 0.202165, -0.739441)
+  q2 = (-0.381849, 0.565838, -0.0257765, -0.730311)
+compute the Hamilton product q1 * q2 and confirm the result is still unit length. Which rotation does the product correspond to — applying q1 first or q2 first?<｜Assistant｜><think>Hamilton product, XYZW storage. The component formulas are
+  x = w1*x2 + x1*w2 + y1*z2 - z1*y2
+  y = w1*y2 - x1*z2 + y1*w2 + z1*x2
+  z = w1*z2 + x1*y2 - y1*x2 + z1*w2
+  w = w1*w2 - x1*x2 - y1*y2 - z1*z2
+
+x: -0.739441*-0.381849 + 0.458471*-0.730311 + -0.449623*-0.0257765 - 0.202165*0.565838 = -0.155274
+y: -0.739441*0.565838 - 0.458471*-0.0257765 + -0.449623*-0.730311 + 0.202165*-0.381849 = -0.155418
+z: -0.739441*-0.0257765 + 0.458471*0.565838 - -0.449623*-0.381849 + 0.202165*-0.730311 = -0.040851

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.</think>q1 * q2 = (-0.155274, -0.155418, -0.040851, 0.974714) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>A texel reads (0.755, 0.349, 0.651) in an 8-bit sRGB texture. Convert it to linear light, and explain how much error the common `pow(x, 2.2)` shortcut introduces. Then average the three channels the correct way and say why averaging in sRGB directly is wrong.<｜Assistant｜><think>The real sRGB transfer function is piecewise — a linear toe below 0.04045 and a 2.4 power above:
+  lin = u/12.92                     for u ≤ 0.04045
+  lin = ((u + 0.055)/1.055)^2.4     otherwise
+
+  0.755 → 0.530345   (pow2.2 shortcut: 0.538869, error 1.61%)
+  0.349 → 0.0998871   (pow2.2 shortcut: 0.098677, error 1.21%)
+  0.651 → 0.381351   (pow2.2 shortcut: 0.388936, error 1.99%)
+
+The shortcut is close in the midtones and diverges in the shadows, because it has no linear toe: as u → 0 the true curve is linear with slope 1/12.92 while u^2.2 heads to zero far faster. That is why shadow terms and dark albedo values are the first thing to look wrong when someone hand-rolls the conversion.
+
+Averaging: mean of the sRGB values is 0.585, but sRGB is a perceptual encoding, not a quantity of light — adding two encoded values does not correspond to adding two amounts of photons. The correct route is decode → average → re-encode:
+  mean(linear) = 0.337194
+  re-encoded   = 0.615712
+versus 0.585 from the naive average — a visible difference, and always biased in the same direction.</think>Linear values: (0.530345, 0.0998871, 0.381351).
+
+The `pow(x, 2.2)` shortcut gives (0.538869, 0.098677, 0.388936) — within a couple of percent in the midtones but increasingly wrong toward black, since it drops the linear toe below 0.04045.
+
+Correct channel average: decode to linear, average to 0.337194, re-encode to 0.615712. Averaging the sRGB values directly gives 0.585, which is wrong because sRGB is a perceptual encoding — mipmaps, blurs and blends must all happen in linear space. In three.js this is what `SRGBColorSpace` on the texture and `outputColorSpace` on the renderer handle for you.<｜end▁of▁sentence｜>

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.</think>q1 * q2 = (0.108966, 0.0270475, 0.227702, -0.967237) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>

+  z = w1*z2 + x1*y2 - y1*x2 + z1*w2

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.</think>q1 * q2 = (0.427411, 0.205067, 0.200547, -0.857349) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>

+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
+...
+</｜DSML｜invoke>
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+</｜DSML｜invoke>
+</｜DSML｜tool_calls>
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.
+
+Otherwise, output directly after </think> with tool calls or final response.
+
