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.

Transform::operator*

Transform operator*(const Transform& other) const;

组合两个变换。当 A * B 时,表示先应用 B,再应用 A。结果变换先对点进行 B 变换,再进行 A 变换。

组合计算:

  • position = position + rotation * (scale * other.position)
  • rotation = rotation * other.rotation
  • scale = scale * other.scale

参数:

  • other - 要组合的另一个变换

返回: Transform - 组合后的变换

线程安全: (无锁,非线程安全)

复杂度: O(1)

示例:

#include "XCEngine/Core/Math/Transform.h"
#include "XCEngine/Core/Math/Vector3.h"

using namespace XCEngine::Math;

void OperatorMultiplyExample() {
    Transform parent;
    parent.position = Vector3(10.0f, 0.0f, 0.0f);
    parent.scale = Vector3(2.0f, 2.0f, 2.0f);

    Transform child;
    child.position = Vector3(5.0f, 0.0f, 0.0f);

    Transform combined = parent * child;

    Vector3 worldPos = combined.TransformPoint(child.position);
}
