Those models which are used in movies or games generally belong to animatable models, which have not only the geometry data but also the motion data. Actually, generating animatable models and editing the motions cost a lot of time comparing with the whole production pipeline. Therefore we want to propose several new and good algorithms to make the user to edit the motion and model easily and quickly. However, when editing the motion of a surface model, the volume of the model may be changed before and after the editing. Hence, to preserve the volume of the model while editing is also one of the goals of this project. Furthermore, to reduce the data size of the animatable model, we also want to propose a mesh simplification method for animatable model while keeping the frame-to-frame coherence. Many research groups also pay much attention to these topics. In this two years research project, we plan to develop a 3D animatable model processing system including several modules which contain motion editing with volume preserving and mesh simplification of animatable models.三維動態模型動作編輯體積保持網格簡化animatable modelvolume preservingmesh simplification
