# Transform::Inverse
|
|
|
|
```cpp
|
|
Transform Inverse() const;
|
|
```
|
|
|
|
返回当前变换的逆变换。逆变换满足 `transform * transform.Inverse() == Identity()`。
|
|
|
|
计算方式：
|
|
- 旋转取反：先计算旋转的逆（四元数共轭）
|
|
- 缩放送原：取倒数
|
|
- 位置：将原点相对于当前点的偏移，经逆旋转和逆缩放后取反
|
|
|
|
**参数：** 无
|
|
|
|
**返回：** `Transform` - 当前变换的逆变换
|
|
|
|
**线程安全：** ❌（无锁，非线程安全）
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include "XCEngine/Math/Transform.h"
|
|
#include "XCEngine/Math/Vector3.h"
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
void InverseExample() {
|
|
Transform transform;
|
|
transform.position = Vector3(10.0f, 0.0f, 0.0f);
|
|
transform.rotation = Quaternion::Identity();
|
|
transform.scale = Vector3(2.0f, 2.0f, 2.0f);
|
|
|
|
Transform inverse = transform.Inverse();
|
|
|
|
Transform identity = transform * inverse;
|
|
}
|
|
```
