# Vector3 * Quaternion
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 operator*(const Quaternion& q, const Vector3& v)
|
||
|
|
```
|
||
|
|
|
||
|
|
用四元数旋转向量。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `q` - 旋转四元数
|
||
|
|
- `v` - 要旋转的向量
|
||
|
|
|
||
|
|
**返回：** `Vector3` - 旋转后的向量
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Quaternion rot = Quaternion::FromEulerAngles(0.0f, 90.0f * DEG_TO_RAD, 0.0f);
|
||
|
|
Vector3 forward = Vector3::Forward();
|
||
|
|
Vector3 rotated = rot * forward; // 绕 Y 轴旋转 90 度
|
||
|
|
```
