Matrix4x4::Decompose
void Decompose(Vector3& translation, Quaternion& rotation, Vector3& scale) const
将变换矩阵分解为平移、旋转和缩放三个独立分量。
参数:
translation- 输出参数,接收平移向量rotation- 输出参数,接收旋转四元数scale- 输出参数,接收缩放向量
返回: (无)
线程安全: ✅
复杂度: O(1)
示例:
#include "XCEngine/Core/Math/Matrix4.h"
#include "XCEngine/Core/Math/Vector3.h"
#include "XCEngine/Core/Math/Quaternion.h"
using namespace XCEngine::Math;
Matrix4 transform = Matrix4::TRS(
Vector3(1.0f, 2.0f, 3.0f),
Quaternion::FromEuler(45.0f, 0.0f, 0.0f),
Vector3(2.0f, 2.0f, 2.0f)
);
Vector3 translation;
Quaternion rotation;
Vector3 scale;
transform.Decompose(translation, rotation, scale);
// translation = (1.0f, 2.0f, 3.0f)
// rotation 表示 45 度 X 轴旋转
// scale = (2.0f, 2.0f, 2.0f)
