Bounds::GetClosestPoint
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:
#include <XCEngine/Math/Bounds.h>
#include <XCEngine/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
