# Bounds::Bounds
|
|
|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
|
Bounds()
|
|
|
|
|
|
Bounds(const Vector3& center, const Vector3& size)
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
构造一个 Bounds 对象。默认构造函数创建中心为原点、范围为零的包围盒。
|

|
**参数：**
|
|
|
|
|
|
- `center` - 包围盒的中心点
|
|
|
|
|
|
- `size` - 包围盒的完整尺寸（非 extents，构造时会自动除以 2）
|
|
|
|
|
|
|
|
|
|
|
|
**返回：** 无
