摘要
构建一个规模可扩展、功能可扩充、高效的异构型分布式虚拟环境(Distributed Virtual Environments,简称DVE)系统是一个极具挑战的课题。针对DVE系统的规模扩展性问题,文章提出了融合空间分区、兴趣管理、一致性/并发控制和状态推算(Dead Reckoning)多种技术的一个通用框架,并对这些关键技术进行了研究;针对DVE系统的功能可扩充和异构性问题,文章提出了采用实时CORBA/TAO支持DVE系统实现的方法。上述方法为解决DVE系统的规模扩展性、功能扩充性和异构性提供了一个框架和技术上的完整方案。最后,文章给出了依据该方案开发的一个DVE系统实例。
It is a challenging problem to build a scalable, function expansible and heterogeneous Distributed Virtual Environment. The paper presents a general framework which incorporates technologies of space partition, interest management, consistency / concurrency control and Dead Reckoning to support DVE's scalability. These technologies mentioned above are discussed later. To resolve the problem of DVE's function expansibility and heterogeneity , real - time CORBA/TAO are used to support the implementation of DVE system. This method provides DVE system with a frame and technical integrated project to resolve the problem of DVE's scalability, function expansibility and heterogeneity. In the end of the paper, a case of DVE developed on the basis of the project mentioned above is presented.
