摘要:
 协同虚拟现实系统是在分布式虚拟环境基础上发展起来的一种智慧环境，在情景创设、协同工作、高交互性和实时性等方面具有明显优势。在梳理协同虚拟现实的定义与功能、模型与分类的基础上，研究了协同虚拟现实的建模技术和模型优化技术，重点探讨了协同感知的实现、用户替身的实现和协同通讯环境的实现方法。为解决多用户操作冲突，研究了采用对象锁和优先级控制法的并发控制技术。结合“协同搬凳”虚拟现实实例，阐述了协同虚拟现实的设计流程和关键技术。测试表明，基于VRML的协同虚拟现实系统能满足低带宽、实时性要求，提出的定时采集和发送数据的方法，满足多用户协同虚拟现实的需要。
Abstract:
 Collaborative virtual reality system is a kind of intelligent environment based on distributed virtual environment,which has ob-vious advantages in scene creation,cooperative work,high interactive and real-time,etc. In this paper,it gets research on collaborative virtual reality modeling technology and model optimization technology based on the definition and function,and model and category of virtual reality,and focuses on the realization of collaborative perception,user’ s avatar and collaborative communication environment. To solve multi user operation conflict,the concurrency control technology is studied using object lock and priority control method,elaborating design process and key technology of collaborative virtual reality combined with the“cooperative move stool” example of virtualreality. Tests show that the VRML-based collaborative virtual reality system has low bandwidth and real-time,which can meet the requirements of multi user virtual reality.
