# Transform
|
||
|
|
|
||
|
|
3D 变换结构体，包含位置、旋转和缩放，用于层次化变换。
|
||
|
|
|
||
|
|
**头文件：** `#include <XCEngine/Math/Transform.h>`
|
||
|
|
|
||
|
|
**命名空间：** `XCEngine::Math`
|
||
|
|
|
||
|
|
## Space 枚举
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
enum class Space { Self, World };
|
||
|
|
```
|
||
|
|
|
||
|
|
## 结构体定义
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
struct Transform {
|
||
|
|
Vector3 position = Vector3::Zero();
|
||
|
|
Quaternion rotation = Quaternion::Identity();
|
||
|
|
Vector3 scale = Vector3::One();
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
