网上虚拟现实交互技术的实现

Implementaion of technology of virtual reality interaction on internet

通过对虚拟现实事例的分析,阐述了VRML的工作原理及特性,虚拟现实技术与Java技术的结合,增加了虚拟现实技术与用户的交互功能.介绍了VRML与用户之间交互的核心体系,并分析了一个复杂的VRML场景中运用Java和Javascirpt与用户交互的过程.用户通过JAVA,操纵场景中的任何物体,并改变物体相应的属性.

The paper describes the working prin ciple of the VRML with the sample of Vi rtual Reality,and the association of the virtual reality t echnology and Java technology inten sifis the interaction among the user,virtual reality and Java,introduces the kernel scheme of the VRML of the interaction between VRML and user,analyses process of interaction of user with J ava and Javascorpt in a complex VRML s cene .Under the interface provided by Java ,The user can control any obje cts and change the attributes .
