| 摘 要： | 三维网格单一位率压缩技术将网格的几何信息和拓扑连接信息分开独立压缩.进行连接信息压缩时,通常对某种结构表示的网格连接信息进行某种形式的遍历,对遍历过程进行信息编码压缩;压缩几何信息时,一般需要经过量化、预测和熵编码3个处理过程.通过对该类算法进行研究总结,提出并设计了一个针对三角网格的单一位率压缩统一模式框架,并基于OpenGL和Visual C 6.0,以Edgebreaker算法为例进行了实验.

| Abstract: | A single-rate mesh compression algorithm encodes and compresses geometry data and topological connectivity data separately in 3D mesh compression.The connectivity encoding process is generally a traversal of the mesh information which is represented by some data structure,then it encodes this traversal with coding techniques;The geometry encoding process is usually formed by three steps: quantization,prediction and entropy coding.A unified framework is proposed for 3D mesh single-rate compression to facilitate the resea-rches to develop these algorithms,and program is based on OpenGL in Visual C 6.0 environment with the Edgebreaker algorithm. |
