# Matrix4x4::RotationZ
```cpp
2026-03-20 02:35:15 +08:00
static Matrix4x4 RotationZ(float radians)
```

创建绕 Z 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)
2026-03-20 02:35:15 +08:00
**返回:** 绕 Z 轴旋转的矩阵
**线程安全:** ✅
**复杂度:** O(1)
**示例:**
```cpp
#include "XCEngine/Core/Math/Matrix4.h"
#include "XCEngine/Core/Math/Vector3.h"
2026-03-20 02:35:15 +08:00
using namespace XCEngine::Math;
Matrix4 rotZ = Matrix4::RotationZ(3.14159265f / 2.0f); // 90 度
Vector3 point(1.0f, 0.0f, 0.0f);
Vector3 rotated = rotZ.MultiplyVector(point);
// point 绕 Z 轴旋转 90 度
```
