分布式虚拟现实仿真环境中的数据过滤技术研究

Research on Data Filtering Technology in Distributed Virtual Reality Simulation Environment

减少网络通讯负载一直是分布交互仿真环境致力解决的问题。本文针对分布式虚拟现实仿真环境DVSE2 0 0 0遇到的拨号网络通讯瓶颈问题 ,讨论了基于数据转发器的实体状态数据包压缩技术及静态实体数据包传送技术。另外本文还基于大规模分布交互仿真环境介绍了兴趣管理技术 ,并提出了多阈值DR技术的思想。

How to reduce network traffic is an important problem for Distributed Interactive Simulation. This paper discusses two approaches to data filtering: ESPDU compression technique and quiescent entity management technique, which help to resolve the network traffic in DVSE2000, and also introduces the technology of Interest Management in Large Scale Virtual Environment, and issues the technology of multi threshold DR(Dead Reckon) based on the environment. The technology of multi threshold DR prouides a new way to reduce communication costs.
