摘　　要：三维几何数据压缩是指对描述三维场景的模型数据进行压缩，以便于模型数据的存储和网络传输，在分布式虚拟现实、协同应用、多用户视频游戏、模型数据在计算机内部的存储和传输有着非常重要的意义．文中介绍了三维几何数据压缩方法，分面向单分辨率模型的压缩和面向多分辨率模型的压缩两类进行阐述，并讨论了当前最新的研究进展，分析了目前尚存在的问题和研究前景．D geometry compression is the technique which aims at the compression of model data in 3D scenery. It is important for distributed virtual reality,co operation, and multi player video games, as well as for storing and transfering data in computer. A 3D geometry compression method is introduced in this paper. Existing methods are classified into two kinds according to their usage for single resolution model and multi resolution model. The recent achievements of 3D compression are discussed and the existing problems are analysed.
