# Bounds::GetClosestPoint
|
|
|
|
```cpp
|
|
Vector3 GetClosestPoint(const Vector3& point) const
|
|
```
|
|
|
|
获取包围盒上最接近给定点的点。如果点在盒内，则返回该点本身；如果在盒外，则返回该点在盒面上的投影点。
|
|
|
|
**参数：**
|
|
- `point` - 参考点
|
|
|
|
**返回：** `Vector3` - 盒上最接近的点
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Core/Math/Bounds.h>
|
|
#include <XCEngine/Core/Math/Vector3.h>
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Bounds bounds(Vector3(0.0f, 0.0f, 0.0f), Vector3(2.0f, 2.0f, 2.0f));
|
|
|
|
Vector3 inside = bounds.GetClosestPoint(Vector3(0.0f, 0.0f, 0.0f));
|
|
// returns (0, 0, 0) since point is inside
|
|
|
|
Vector3 outside = bounds.GetClosestPoint(Vector3(10.0f, 0.0f, 0.0f));
|
|
// returns (1, 0, 0) - closest point on box surface
|
|
```
