# Quaternion::FromRotationMatrix
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Quaternion FromRotationMatrix(const Matrix4x4& matrix)
|
||
|
|
```
|
||
|
|
|
||
|
|
从旋转矩阵创建四元数。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `matrix` - 旋转矩阵
|
||
|
|
|
||
|
|
**返回：** `Quaternion` - 表示相同旋转的四元数
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Matrix4 rotMat = Matrix4::RotationY(90.0f * DEG_TO_RAD);
|
||
|
|
Quaternion quat = Quaternion::FromRotationMatrix(rotMat);
|
||
|
|
```
