# Box
|
||
|
|
|
||
|
|
带变换的有向包围盒 (OBB) 结构体。
|
||
|
|
|
||
|
|
**头文件：** `#include <XCEngine/Math/Box.h>`
|
||
|
|
|
||
|
|
**命名空间：** `XCEngine::Math`
|
||
|
|
|
||
|
|
## 结构体定义
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
struct Box {
|
||
|
|
Vector3 center = Vector3::Zero();
|
||
|
|
Vector3 extents = Vector3::Zero();
|
||
|
|
Matrix4x4 transform = Matrix4x4::Identity();
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
## 构造函数
|
||
|
|
|
||
|
|
- `Box()` - 默认构造
|
||
|
|
- `Box(const Vector3& center, const Vector3& extents)` - 从中心和半长构造
|
||
|
|
|
||
|
|
