摘    要:讨论了一个基于 PC的廉价 CAVE系统的实现方法 .FCCAVE使用 4台微机配合中低档的图形显示卡构成图形绘制系统 ,代替 SGI工作站和 Reality Engine高档工作站图形卡 .PCCAVE整体上是一个主从式并行计算结构 ,主节点提供人机交互控制接口 ,从节点接受主节点命令和绘制立体图像 .PCCAVE的通信子系统使用 MPI实现 ,实现了并行计算的同步控制和智能信息代理服务 ,图形子系统以 Direct X和 Open GL 作为底层图形 API.还研究了系统的主要瓶颈和性能指标 .利用该系统实现了浙江大学的校园漫游 .结果表明该系统的许多指标都超越或者接近于 SGI Onyx2 ,具有良好的推广前景和较高的实用价值 .

Abstract:A non expensive CAVE system is constructed by using networked PCs running on Windows2000. The subsystem consists of 4 PCs with low AGP cards to substitute SGI workstations with RealityEngine graphics cards. Whole architecture is master slave. Mater node provides man machine interaction interface and control the whole system while slave nodes receive commands from master node to render stereo images. Its communication system is based on MPI to implement synchronization of parallel computing and intelligent information broker, its graphics API is DirectX and OpenGL. Its performance and bottlenecks are analyzed in this paper. An application is given to walk through the campus of Zhejiang University. Tracking and other interaction devices and 3D audio will be integrated into this system later
Keywords:CAVE  virtual reality  distributed computing  MPI  distributed virtual environment
