摘要: 多分辨率分析(Multi resolutionAnalysis)和法线网格(Normalmeshes)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(ProgressiveGeometryCompression)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。

Abstract: 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.

Key words: multi-resolution, progressive compression, normal mesh, normal polygon
