Transform::operator*
Transform operator*(const Transform& other) const;
组合两个变换。当 A * B 时,表示先应用 B,再应用 A。结果变换先对点进行 B 变换,再进行 A 变换。
组合计算:
position = position + rotation * (scale * other.position)rotation = rotation * other.rotationscale = scale * other.scale
参数:
other- 要组合的另一个变换
返回: Transform - 组合后的变换
线程安全: ❌(无锁,非线程安全)
复杂度: O(1)
示例:
#include "XCEngine/Math/Transform.h"
#include "XCEngine/Math/Vector3.h"
using namespace XCEngine::Math;
void OperatorMultiplyExample() {
Transform parent;
parent.position = Vector3(10.0f, 0.0f, 0.0f);
parent.scale = Vector3(2.0f, 2.0f, 2.0f);
Transform child;
child.position = Vector3(5.0f, 0.0f, 0.0f);
Transform combined = parent * child;
Vector3 worldPos = combined.TransformPoint(child.position);
}
