面向对象的虚拟环境数据模型框架

Object-Oriented Data Model Framework of Virtual Environment

虚拟现实（VirsualReality）技术是一门由多媒体构成的多维信息空间的综合技术，因此，虚拟环境（Vir－sualEnviroment）的模型建立是大型的、复杂的数据构造。该文介绍了一种分层次的、可继承的、模块化的、易维护的程序设计方法？面向对象技术，并探讨了应用面向对象技术建立虚拟环境数据模型的一般框架体系。

Virtual reality technology is a comprehensive technology of cyberspace consisting of multimedia. VirtualEnvironment Modelling, hence, are very numberious and complicated data constrution. In this paper, we introducea programing method which is hierarchical, inheritable, modularized, and maintainable──oioject-orented programming technolog, and discuss how to use this technology to construct a general framework of virtual environmentdata model.
