Survey of sketch-based technique aiding 3D animation
基于草绘辅助3D动画综述*

Improving the efficiency of three dimension animation producing is a key problem in animation industry. As the techniques of computer hardware and computer aiding develop fast, that makes solving the problem possible. The user interface based on sketch has been focused on many researchers. First of all, this paper reviewed the technique of sketch briefly, after that, summarized how it used in the three dimension animation. Finally, prospected its development in the future.
