# Matrix3::RotationZ
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Matrix3 RotationZ(float radians)
|
||
|
|
```
|
||
|
|
|
||
|
|
返回绕 Z 轴旋转的 3x3 旋转矩阵。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `radians` - 旋转角度（弧度）
|
||
|
|
|
||
|
|
**返回：** `Matrix3` - 绕 Z 轴旋转的矩阵
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Matrix3 rotZ = Matrix3::RotationZ(Math::Radians(45.0f));
|
||
|
|
// 结果（绕 Z 轴旋转 45 度）:
|
||
|
|
// [ 0.707 -0.707 0]
|
||
|
|
// [ 0.707 0.707 0]
|
||
|
|
// [ 0 0 1]
|
||
|
|
```
