摘要:

通过对要传输的三维图形进行分层处理,并在接收端建立BSP二叉树,提取与视觉相关的层和可见三角形信息,使传输数据迅速减少,但又不影响接收端对敏感数据的处理和显示。

关键词: 压缩, 三角带, BSP树

Abstract:

A geometry compression algorithm for 3-D graphics was presented. It divided 3-D graphics into many layers, created BSP tree in the receiver, and extracted the view-dependent layers and visible triangulars information. This algorithm can greatly reduce the transmitted data of 3-D graphics without affecting the process and display of sensitive data.

Key words: compression, triangle strip, BSP tree
