|
|
|
||
|
|
## 默认构造函数
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Box() = default;
|
||
|
|
```
|
||
|
|
|
||
|
|
构造一个盒体，`center` 为原点，`extents` 为零向量，`transform` 为单位矩阵。
|
||
|
|
|
||
|
|
## 带参构造函数
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Box(const Vector3& center, const Vector3& extents)
|
||
|
|
```
|
||
|
|
|
||
|
|
从指定的中心和半长构造一个盒体。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `center` - 盒体的中心点
|
||
|
|
- `extents` - 盒体在各轴向上的半长（从中心到面的距离）
|
||
|
|
|
||
|
|
**返回：** 无
|

|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Math/Box.h>
|
||
|
|
#include <XCEngine/Math/Vector3.h>
|
||
|
|
|
||
|
|
using namespace XCEngine::Math;
|
||
|
|
|
||
|
|
Box box(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 2.0f, 1.5f));
|
||
|
|
```
