摘　　要：与网络的结合使虚拟现实技术飞速发展,但实际应用中有限的网络带宽、海量场景数据的传输等问题使其受到严重制约。本文提出将DHT技术引入到虚拟场景中,通过对场景数据的分块处理及对用户的管理实现对海量三维场景数据的有效发布及获取。本文深入探讨了基于DHT原理的数据分布式存储、发布及获取机制。实验结果表明,该方法能够对虚拟场景数据有效发布及获取,并使数据获取效率有所提升。Web based Virtual Reality has developed rapidly in recent years.In practice,however,the problem of realizing high-speed transmission of massive virtual scene data with limited bandwidth restricts the speed of its development.In order to publish and acquire 3D scene data in a more effective and efficient way,this paper introduces DHT technology in virtual environment,achieving the goal through partitioning and distributing data files and nodes management.In this paper distributed storage and the mechanism for publishing and acquiring scene data are analyzed and discussed.Performance analysis shows that the approach can be applied to the release and retrieval of virtual scene data with good performance,and the efficiency of acquiring data is improved as well.
