# Quaternion::Inverse
|
|
|
|
```cpp
|
|
Quaternion Inverse() const;
|
|
```
|
|
|
|
求四元数的逆。如果四元数已归一化，逆等于共轭。
|
|
|
|
**返回：** 四元数的逆
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Math/Quaternion.h>
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Quaternion q = Quaternion::FromAxisAngle(Vector3::Up(), Math::Radians(90.0f));
|
|
Quaternion inv = q.Inverse();
|
|
|
|
Quaternion identity = q * inv;
|
|
```
