Matrix4x4::GetRotation
Quaternion GetRotation() const
从变换矩阵中提取旋转分量。将矩阵转换为对应的四元数表示。
参数: (无)
返回: 旋转四元数
线程安全: ✅
复杂度: O(1)
示例:
#include "XCEngine/Math/Matrix4.h"
#include "XCEngine/Math/Quaternion.h"
using namespace XCEngine::Math;
Quaternion expected = Quaternion::FromEuler(0.0f, 90.0f, 0.0f);
Matrix4 transform = Matrix4::TRS(
Vector3(0.0f, 0.0f, 0.0f),
expected,
Vector3(1.0f, 1.0f, 1.0f)
);
Quaternion rotation = transform.GetRotation();
// rotation 表示相同的旋转
