Compared to the extensive works on static model approximation  very little attentions have been paid to animated models. In this paper  we propose a new method to approximate animated models with local area distortion and deformation degree control. Our method uses an improved quadric error metric guided by a local area distortion measurement as a basic hierarchy. Also  we define a deformation degree parameter to be embedded into the aggregated quadric errors  so areas with large deformation during the animation can be successfully preserved. Finally  a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast  easy to implement  and as a result good quality dynamic approximations with well-preserved sharp features can be generated at any given frame. 2010 SPIE.   deforming surface simplification based on feature preservation 会议论文  OAI收割 6th International Conference of Entertainment Computing, ICEC 2007, Shanghai, China, September Shixue Zhang; Enhua Wu   |  收藏  |  浏览/下载：9/0  |  提交时间：2011/06/29 Approximation theory  Feature extraction  Mesh generation   Difference schemes on non-uniform mesh and their application 期刊论文  OAI收割 Progress in Natural Science, 2004, 卷号: 14, 期号: 10, 页码: 848-854 作者:  Ma YW(马延文);  Gao H(高慧);  Fu DX(傅德薰);  Li XL(李新亮) 收藏  |  浏览/下载：933/51  |  提交时间：2009/08/03 Scheme On Non-Uniform Mesh  High Order Accurate Scheme  Compact Difference Approximation  Simulations
