ssdfasd b414bc5326 refactor(docs): Fix broken links across multiple modules
Fixed broken references:
- texture-import-settings: Fix 16 files referencing wrong overview filename
- math/rectint: Fix 9 method links (rectint-* → get*, contains, intersects)
- rhi/opengl/device: Fix 8 cross-references (opengl-* → */**)
- resources/mesh: Fix meshsection and vertexattribute links
- rhi/d3d12/sampler: Fix RHISampler reference path
- math/vector3: Fix projectonplane → project-on-plane
- rhi/opengl/command-list: Remove broken ClearFlag enum ref
- rhi/opengl/device: Create 2 new method docs (MakeContextCurrent, GetNativeContext)
- rhi/device: Fix device-info types reference

All 0 broken references remaining.

Quaternion::FromAxisAngle

static Quaternion FromAxisAngle(const Vector3& axis, float radians);

从轴角表示创建四元数。使用半角公式进行转换。

参数:

  • axis - 旋转轴(会被归一化)
  • radians - 旋转角度(弧度)

返回: 表示该旋转的四元数

线程安全:

复杂度: O(1)

示例:

#include <XCEngine/Core/Math/Quaternion.h>
#include <XCEngine/Core/Math/Vector3.h>
#include <XCEngine/Core/Math/Math.h>

using namespace XCEngine::Math;

Quaternion q = Quaternion::FromAxisAngle(Vector3::Up(), Math::Radians(90.0f));
