Abstract :
Thinking of the fact that Euler angles will probably cause the movement non-uniform and gimbal lock, we employ Clifford geometric algebra, which establishes a coordinate-free, homogeneous model for different dimensional spaces, to solve the problem. In addition, because of the multidimension of Clifford algebra, it has become possible for us to introduce the weight factors to establish the skeleton animation.
