基于法线网格的渐进压缩

多分辨率分析(Multi-resolution Analysis)和法线网格(Normal meshes)是近年来进行三维网格图形处理和网格压缩的新方法。该文在这两项技术的基础上，提出并实现了三维网格的多分辨率分析及其渐进几何压缩(Progressive Geometry Compression)方案，研究了基于细分的法线网格在多分辨率分析中的边界处理问题。实验结果表明，利用法线网格的多分辨率分析结合法向多边形构造方法来处理边界，可以取得非常高的压缩率和较好的重构效果。

Progressive compression scheme based on normal meshes

Multi-resolution analysis and normal mesh are new methods in meshes compression and other operation of 3D graphics recently. In this paper, a scheme of multi-resolution analysis and progressive geometry compression based on normal meshes was proposed, and the concerned problems of boundary in the multi-resolution analysis based on subdivision were attempted. The results showed that a satisfied effect and high compression rate could be achieved, by combining the multi-resolution analysis of normal meshes and normal polygons made schemes to manage the boundaries.
