This paper proposed a new approach for modeling and animation of characters. Through using ball B-splines, an automatic character building model based on skeleton was realized and a character animation generation method driven by data was obtained. When the skeleton of a character was given, these radii on joints were obtained according to the length of bones in anthropometry. Then ball B-spline curves and surfaces were generated to represent characters through interpolating joint points and radii on them. The modeling method is rapid. Furthermore, by using motion data to update control points, real-time animation is achieved.
