Transform::TransformPoint
Vector3 TransformPoint(const Vector3& point) const;
将一个点从本地空间变换到世界空间。计算结果为 position + rotation * (scale * point),即先缩放、再旋转、最后平移。
此方法适用于变换顶点位置等考虑平移的点。
参数:
point- 本地空间中的点
返回: Vector3 - 世界空间中的变换后点
线程安全: ❌(无锁,非线程安全)
复杂度: O(1)
示例:
#include "XCEngine/Core/Math/Transform.h"
#include "XCEngine/Core/Math/Vector3.h"
using namespace XCEngine::Math;
void TransformPointExample() {
Transform transform;
transform.position = Vector3(10.0f, 0.0f, 0.0f);
transform.rotation = Quaternion::Identity();
transform.scale = Vector3(2.0f, 2.0f, 2.0f);
Vector3 localPoint(1.0f, 2.0f, 3.0f);
Vector3 worldPoint = transform.TransformPoint(localPoint);
}
