WebIn the 2D case, rotation was always performed around the origin. In 3D space, we have the x -, y - and z -axis around which can be rotated The rotation around the z -axis corresponds exactly to a 2D rotation, since only the x - and y -coordinates of a point are changed Rotation around the z -axis by the angle \alpha : WebIn this video I'll present the second core 3D transformation - the rotation.
