In this paper  we propose a new method for generating progressive animated models based on local feature analysis and deformation area preservation. We propose the use of solid angle and height value for a non-hyperbolic vertex to define the local feature parameter. This local factor is embedded to the vertex quadric error matrix when calculating the edge collapse cost. In order to preserve the areas with large deformation  we add deformation degree weight to the aggregated quadric errors when computing the unified edge contraction sequence. 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 fine details can be generated at any given frame. 2010 IEEE.   EC-CageR: Error controllable cage reverse for animated meshes (CPCI-S收录) 会议 作者:  Lu, Huina[1];  Li, Guiqing[1];  Xian, Chuhua[1];  Zhang, Zhibang[1];  Yin, Mengxiao[1] 收藏  |  浏览/下载：4/0  |  提交时间：2019/04/11 CageR  Animated meshes  Deforming meshes  Mean-value coordinates  Poisson based weight reduction
