摘要

VR (Virtual Reality) technology is entering DVR (Distributed Virtual Reality) era. DVR need to meet the real time requirement. This requirement results in more complex and heavier computational tasks, significantly increasing the load of a node in a DVR. High-performance parallel graphic system can be used, but they are very expensive. To decrease the cost and make full use of existing network resources, we present a parallel graphic rendering system in this paper. The system adopts Master-Slave model in network topology. COBRA is used as the network computational environment of the distributed rendering system. To further improve the performance of system, we used many new techniques, such as task division based on object space, task overlay and dynamic load balancing. The experiment results indicate that the time each computer needed to render dropped with the increase of the number of the computers contributing to the computation. Although the transferring time of the network also grows, it has no remarkable impact on the change of overall time because only a little more controlling information need to be transferred than before.
