Matrix4x4::Inverse
Matrix4x4 Inverse() const
返回矩阵的逆矩阵。如果矩阵的行列式接近零(不可逆),则返回单位矩阵。
参数: (无)
返回: 逆矩阵;如果矩阵不可逆则返回单位矩阵
线程安全: ✅
复杂度: O(n³),对于 4x4 矩阵固定为 64 次基本运算
示例:
#include "XCEngine/Core/Math/Matrix4.h"
using namespace XCEngine::Math;
Matrix4 transform = Matrix4::TRS(
Vector3(1.0f, 2.0f, 3.0f),
Quaternion::FromEuler(0.0f, 45.0f, 0.0f),
Vector3(2.0f, 2.0f, 2.0f)
);
Matrix4 inv = transform.Inverse();
Matrix4 identity = transform * inv;
// identity 接近单位矩阵
