Transform::InverseTransformDirection
Vector3 InverseTransformDirection(const Vector3& direction) const;
将一个方向向量从世界空间逆变换到本地空间。计算结果为 rotation.Inverse() * direction / scale。
此方法是 TransformDirection 的逆操作。
参数：
direction- 世界空间中的方向向量
返回： Vector3 - 本地空间中的逆变换后方向
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 InverseTransformDirectionExample() {
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 worldDir(0.0f, 2.0f, 0.0f);
Vector3 localDir = transform.InverseTransformDirection(worldDir);
}
