基于Internet的多用户共享虚拟环境框架的研究

多用户共享虚拟环境是指网络化的协同虚拟现实系统，在该环境中多个用户之间通过各自的三维图形表示实现在虚拟环境中的多人感知，用户之间的交互以及对虚拟对象的协同操纵，在综合分析现有系统以及Internet的开放性标准化需求基础上，提出了一种基于Internet的多用户共享虚拟环境解决方案，即多用户共享虚拟环境框架（multi-user shared virtual envitonment framework,MSVEF)，该框架描述了多用户虚拟环境的体系结构，定义了基于XML的相关交互协议，通过在原型系统中的初步应用，证明该框架可以支持不同网络平台的用户在同一个虚拟场景中的再现与交互。

MULTI-USER SHARED VIRTUAL ENVIRONMENT FRAMEWORK BASED ON INTERNET

Multi user shared virtual environment refers to a networked collaborative virtual reality system, users can interact with each other and control virtual objects by their graphic representation in the virtual environment. After analyzing some existing systems and the requirement of open and standardization of Internet, a reasonable scheme for multi user shared environment based on Internet is presented, which is called the multi user shared virtual environment framework (MSVEF). The architecture and related collaborative protocol based on XML are defined in the MSVEF. A preliminary prototype application shows that MSVEF can effectively support the representation and collaboration of participants in a different platform in the same virtual scene.
