# Plane::GetClosestPoint
|
|
|
|
```cpp
|
|
Vector3 GetClosestPoint(const Vector3& point) const
|
|
```
|
|
|
|
计算平面上最接近给定点的点。通过将点沿平面法线方向投影到平面上得到。
|
|
|
|
**参数：**
|
|
- `point` - 参考点
|
|
|
|
**返回：** `Vector3` - 平面上最接近给定点的点
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Math/Plane.h>
|
|
#include <XCEngine/Math/Vector3.h>
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
void GetClosestPointExample() {
|
|
Plane plane(Vector3::Up(), 0.0f);
|
|
|
|
Vector3 point(5.0f, 10.0f, 0.0f);
|
|
Vector3 closest = plane.GetClosestPoint(point);
|
|
}
|
|
```
