Research On Consistency Control Of Virtual System Based On Sharing Environments

As the rapid development of computer graphics and network, Virtual Reality has been widely employed in each social realm. One can create and simulate virtual environments in the promotion of modern computer technique, which have evolved from single to network shared. Whether for science research or economic requirement, virtual systems based on sharing environments are becoming a favorite focus. Research on consistency control of those systems is an important orientation nowadays. In this article, we have analyzed the basic technologies of virtual environments and discussed the consistency problem in systems sharing with environments.Virtual scene, which is the core composition of a virtual reality system, can be easily designed and implemented by relevant modeling tools and other techniques. In the beginning, primary traits and leading technologies of virtual system are analyzed in this article. Considering our ultimate research purpose and practicality, a simple methodology based on VRML is introduced here, which can be applied to build virtual systems integrating static structure with dynamic interaction.As for systems based on environments shared, real-time consistency is always a key issue. Research on that question is performed here, and we enter from collision phenomenon between collaborative objects in a shared scene. An algorithm for collision self-response with non-complicated parameters is demonstrated as using mechanical theory together with virtual objects. Experiments have shown that the method we propose could not only achieve perfect action consistency and favorable real-time interactivity, but also advance excellent practicability with its independent of platform.Through prolongation of research on collision, the synchronization and concurrence management is discussed, and the kernel factors influencing the system consistency are illustrated by exploring tree knowledge. Finally a performance evaluation is carried out, which proves our method effective and practicable to consistency control in different virtual systems based on sharing environments and acquires the research purpose.
