The Study Of Distributed Architecture Virtual Roaming Based On Network Uers

Virtual Reality technology is a new research field that includes lots of discipline and fields. The level of the application represents the development of science technology in the country. Distributed Virtual Reality system is the result of VR network development. DVR has wide application fields, and it's worthy in theoretical studies and practice.The whole virtual reality system generally exists a pair of contradiction: the modeling fidelity and real time rendering. As for network users, how to make visual roaming on the net becomes the difficulty. In this article, free communication and visual roaming method between network users in the same visual building environment is mentioned. The main research work is as follows: Introduce the background and significance of this article, and the paper's workand innovation etc. Summarize some relating background knowledge and research job. The researchbasis includes Distributed Visual Reality's characteristic, network model and datatransmission, as well as P2P technology and the present situation and applicationof network building visual roaming. Analyze the feasibility that P2P technology applies to visual roaming, thenpropose the thoughts about this combination between both. Also give out anetwork model based on P2P, and compare it with traditional network pattern,finally illustrate its advantages and prospect. Summarize this paper, in view of the shortages, point out further improvement and upgrading tasks.
