小波网格渐进压缩算法

A Wavelet Progressive Compression Algorithm for Triangle Mesh

对三角网格压缩进行了研究,扩展了基于小波的多决定分析理论,直接对三角网格进行不规则分析。保持网格连通性和几何性基础上,优化改善了曲面逼近质量,提高在每个决定层的压缩率。算法对3D网格连通性和几何性都提供了有效压缩。

This paper extends multiresolution analysis wavelet theory for triangular 3D meshes. Based on a irregular subdivision scheme, the algorithm can be applied directly to irregular meshes, which can be very interesting when one wants to keep the connectivity and geometry of the processed mesh completely unchanged. Optimization of beth the connectivity and geometry of the processed mesh completely unchanged. Optimization of beth the connectivity and geometry of the processed mesh improves the approximation quality and the compression ratio of the scheme at each resolution level. This paper show this algorithm provides an efficient means of compression for beth connectivity and geometry of 3D meshes.
