# Matrix4x4::RotationY
|
|
|
|
```cpp
|
|
static Matrix4x4 RotationY(float radians)
|
|
```
|
|
|
|
创建绕 Y 轴旋转的矩阵。角度为正时,按右手定则逆时针旋转。
|
|
|
|
**参数:**
|
|
- `radians` - 旋转角度(弧度)
|
|
|
|
**返回:** 绕 Y 轴旋转的矩阵
|
|
|
|
**线程安全:** ✅
|
|
|
|
**复杂度:** O(1)
|
|
|
|
**示例:**
|
|
|
|
```cpp
|
|
#include "XCEngine/Math/Matrix4.h"
|
|
#include "XCEngine/Math/Vector3.h"
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Matrix4 rotY = Matrix4::RotationY(3.14159265f / 2.0f); // 90 度
|
|
Vector3 point(1.0f, 0.0f, 0.0f);
|
|
Vector3 rotated = rotY.MultiplyVector(point);
|
|
// point 绕 Y 轴旋转 90 度
|
|
```
