Abstract

Virtual reality technology, which is cyberspace composed of multimedia, is a field of comprehensive technology. It is of three basic feathers, namely, interaction, immersion and imagination so that we have to cope with the need for extremely large data sets, massive amounts of computation, and high-throughput networking. This paper presents an approach for object-oriented data modeling framework of complicated virtual environments. The paper discusses the hierarchical decomposition of objects in virtual environments and reuse of these object data libraries to constitute model of virtual environments. This modeling approach used in the paper makes sure that modeling data can be inherited, modularized, maintained easily so as to control redundant data and reduce the software development time, at the same time, realizes dynamic behaviors of objects to meet the needs of some changes of virtual environments.
