摘　　要：针对分布式虚拟现实应用系统的构建问题,给出一种分布式虚拟现实应用系统的构造方法.指出分布式虚拟现实系统中存在的3种基本构件;重点讨论构件的“语义”互操作问题,通过建立构件的语义模型,提出一种原语-语义构件的构件构造方法,该方法可以解决不存在通信协议情况下的构件之间“语义”互操作问题;给出一种支持可组装的分布式虚拟现实应用系统的基于构件的体系结构以及其中的核心机制和算法.实验结果表明了该体系结构的可用性.This paper presents an approach of constructing the application system in Distributed Virtual Reality. Based on a component model of application system in which three type s of the basic components are discussed, this paper first focuses on the ＂semantic＂ interoperability among components, and presents a Primitive-Semantic component constructing method through a semantic model to deal with the semantic interoperability while the communication protocol among components doesn＇t exist. It then presents a composable Distributed Virtual Reality Component-Based Architecture, including its key mechanism and algorithms. Finally the experimental result demonstrates the usability of this architecture.
