Distributed Virtual Reality System And Its Design

DVR system is the production of VR technology 's development in Internet, it's application fields are very extensive. In this paper, a new network structure for the virtual environment of large-scale war field is put forward firstly; Then, a innovate mechanism of divisional management in virtual environment is introduced, basing on such a mechanism, a communication mechanism made of two independent channels is built after; And then, some physical time synchronization methods fitting for different levels in this system is used, and a improving arithmetic named "chbo" for subsystem built on the LAN(local area network) is introduced. In the end , the mechanism of concurrent control in the system is studied.What's more, all kinds of messages in the system are defined, for witch the uniform format is designed, and the input and output relationships among the parts in the system are analyzed, then, the function structure of the parts are constructed in the system.Finally, the developmental trends about DVR system are accounted for.
