	Optimal multiresolution dynamic models generation based on triangle importance (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Image Analysis and Signal Processing, IASP'2010, April 12, 2010 - April 14, 2010, Xiamen, China 作者: Zhao J.; Zhang S. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 In this paper we propose an efficient method to generate optimal multiresolution dynamic models. By the method we define the triangle importance degree as a weight parameter to be embedded to the edge contraction cost so the new metric can not only measure distance error but also reflect geometric variation of local areas. A deformation degree weight is appended to the aggregated edge contraction cost for the whole animation thus sharp features on areas with large deformation can be preserved. In addition a process of mesh optimization and validity check can further alleviate the geometric distortion of the approximations. Our approach is efficient in operation easy for implementation and as a result high quality of dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.
	Multiresolution animated models generation based on deformation distance analysis (EI CONFERENCE) 会议论文 OAI收割 2009 International Conference on Computer Modeling and Simulation, ICCMS 2009, February 20, 2009 - February 22, 2009, Macau, China Shixue Z.; Enhua W. 收藏 \| 浏览/下载：61/0 \| 提交时间：2013/03/25 In computer graphics animated models have been widely used to represent time-varying data. 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
