Summary

When conventional 3D techniques are used for animating cel look characters in 3DCG, a sense of incongruity may arise due to the dimensional difference from the 2D appearance. To address this problem, we propose a method based on the cel anime techniques to generate behaviors with less 3D nature from motion capture data. In cel anime, inbetweening technique is used to omit motion and emphasize speed, resulting in taste different from that of real motions. In our method, we focus on the speed distribution of the motion capture data and select the most effective poses to realize the effectiveness of inbetweening while omitting redundant motions by reducing the number of poses drawn, thus reproducing typical motions of cel anime.
