Reducing the models complexly is a common way to overcome the rendering limitations. In this paper  2009 IEEE.  we propose an efficient method for generating multiresolution animated models based on deformation distance analysis. Our method obtains different LOD models by performing iterative edge contraction operations. We use deformation distance to analysis the deformation degree of the triangle planes during the whole animation  and define a deformation weight to be added to the aggregated edge contraction cost. Thus features in areas with large deformation can be preserved well. Besides  we propose a mesh optimization method for dynamic model sequence  which can efficiently improve the temporal coherence and reduce visual artifacts between adjacent frames. The results show our approach is efficient  easy to implement  and good quality animated approximations with well-preserved fine details can be generated at any given frame. copy   multiresolution animated models generation based on deformation distance analysis 会议论文 2009 International Conference on Computer Modeling and Simulation, ICCMS 2009, Macau, China, 40576 Shixue Zhang; Enhua Wu 收藏  |  浏览/下载：11/0  |  提交时间：2011/03/20 Animation
