A PC-based distributed multiple display virtual reality system

In this paper, a PC-based distributed multiple-display virtual reality syst em is constructed. The system is a PC-based CAVE environment. Five PCs are used in this system; one is the master responsible for receiving user's inp ut signals, the others are clients for images rendering. Devices are added to synchronize the RGB signals from client PCs. A software library is developed to drive the system properly. The software is designed in object-oriented language and flexibility for different inter face devices is considered. With the proposed system, developers can easily elaborate PC-based virtual reality applications and build PC virtual worlds at much lower cost. (C) 20 01 Elsevier Science B.V. All rights reserved.
