多用户分布式虚拟环境系统MUDVE的实现技术

摘要

介绍了一个多用户分布式虚拟环境实验系统MUDVE.在分析了DVE系统的两种通信模型的优缺点后，提出了一种新的混合通信模型，该模型具有系统扩展性好，通信延迟小，对客户机性能要求低的特点;还介绍了面向对象的场景数据管理、动态负载平衡、用户登录管理等功能的设计和实现.另外，MUDVE系统还提供了一般DVE系统所欠缺的信息服务和资源查找、定位功能.最后给出了系统实现的软硬件平台和实验结果.%An experimental multi-user distributed virtual environment MUDVE is introduced. After analyzing pros and cons of peer-to-peer topology and client-server topology, a new hybrid communication topology is presented, which has the characteristics of low latency and good scalability. The system functions, such as object-oriented data management, dynamic load balancing and user management are discussed. The system also provides functions of information service and resource discovery, which are deficient in the existing DVE systems. Finally the experiment platform is described and the result is shown in grabbed images.
