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.   Surface smoothing and quality improvement of quadrilateral/hexahedral meshes with geometric flow 期刊论文  OAI收割 COMMUNICATIONS IN NUMERICAL METHODS IN ENGINEERING, 2009, 卷号: 25, 期号: 1, 页码: 1-18 作者:  Zhang, Yongjie;  Bajaj, Chandrajit;  Xu, Guoliang   |  收藏  |  浏览/下载：9/0  |  提交时间：2018/07/30 quadrilateral/hexahedral mesh  surface smoothing  feature preservation  quality improvement  geometric flow
