API Reference > geometry-core > CartesianGeometry > Matrix3d > toQuaternion toQuaternion Method convert the matrix to a quaternion. toQuaternion(): Point4d note This calculation requires the matrix to have unit length rows and columns. WARNING: There is frequent confusion over whether a "from quaternion" matrix is organized by rows and columns. WARNING: If you find that the matrix seems to rotate by the opposite angle expect it, transpose it.
