| Abstract: | A new method is presented for dealing with the rotation of a point around an arbitrary axis in three-dimension space ──the real quaternions method.This method provides a simple and elegant representation of rotation.It is easy to generate the quaternion that represents a rotation and to extcact rotation elements from a unit quaternion.It is also easy to obtain the equivalent rotation of a compound rotation around several axes. |
