Abstract: With the development of 3D scan technology and computer graph and improvement of computer performance, 3D data scales increase rapidly, at the same time 3D data processing also must increase. A 3D model search engines must resolve three problems perfectly. The first is resembled calculate way, the second is saving, the third is computing speed. By the grid technique, it can extend the saving space infinitely, and improve the computing speed.

Key words: 3D model, Shape recognition, Grid, 3D search engine

摘要： 随着三维扫描技术和计算机图形学的发展以及计算机性能的提高，三维数据规模迅速增长，同时对三维数据的处理提出了越来越高的要求。一个三维模型搜索引擎必须解决好3个方面的问题：相似算法，存储和速度。通过网格技术可以使存储的空间问题无限扩大，速度问题得到改善。
