Quaternion::FromRotationMatrix
static Quaternion FromRotationMatrix(const Matrix4x4& matrix);
从 4x4 旋转矩阵创建四元数。矩阵必须是正交矩阵且行列式为 1。
参数:
matrix- 旋转矩阵
返回: 对应的四元数
线程安全: ✅
复杂度: O(1)
示例:
#include <XCEngine/Core/Math/Quaternion.h>
#include <XCEngine/Core/Math/Matrix4.h>
using namespace XCEngine::Math;
Matrix4 rotMatrix;
rotMatrix.m[0][0] = 1; rotMatrix.m[0][1] = 0; rotMatrix.m[0][2] = 0;
rotMatrix.m[1][0] = 0; rotMatrix.m[1][1] = 0; rotMatrix.m[1][2] = -1;
rotMatrix.m[2][0] = 0; rotMatrix.m[2][1] = 1; rotMatrix.m[2][2] = 0;
Quaternion q = Quaternion::FromRotationMatrix(rotMatrix);
