# Quaternion::FromAxisAngle
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Quaternion FromAxisAngle(const Vector3& axis, float radians)
|
||
|
|
```
|
||
|
|
|
||
|
|
从轴角创建四元数。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `axis` - 旋转轴（应为单位向量）
|
||
|
|
- `radians` - 旋转角度（弧度）
|
||
|
|
|
||
|
|
**返回：** `Quaternion` - 表示旋转的四元数
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Quaternion rot = Quaternion::FromAxisAngle(Vector3::Up(), 90.0f * DEG_TO_RAD);
|
||
|
|
```
