Individual Three-Dimensional Human Model Animation Based on Conformal Geometric Algebra

摘要

In this paper, the geometric language was used to establish a new algorithm of 3D human model animation. The joint points were extracted from the standard three-dimensional grid model of the human body, and then the connections of joint points were constructed as the human model skeleton. The body model deformation was driven by the joint points to get the key frames, and then insert value between frames to realize three-dimensional human model animation. We uses conformal geometric algebra method to describe three-dimensional human body model, and geometric language was implemented directly (not the coordinate) to do geometry calculations, a stable, fast and efficient algorithm was proposed, also combined with the hierarchical thinking of radial basis function (RBG), to deal with grid distortion caused by the mesh deformation around the joint points and we achieve very good results.
