VRML及其在远程多媒体教学系统中的应用

虚拟现实在当今国际上是一个倍受关注的课题，ＶＲＭＬ作为其重要的开发工具，在社会生活的诸多领域得以广泛地应用。本文重点介绍了虚拟现实技术的特征和发展现状，虚拟现实建模语言ＶＲＭＬ的基本概念、特色功能及其应用的范围。在此基础上，论述了ＶＲＭＬ在现代远程多媒体教学系统中的应用途径和方法，并通过用插值器操作对象、构造视点动画等方法，结合三维动画制作软件设计了一个切实可行的动态模型实例，很好地实现了远程教学过程中的抽象教学内容具体化，进而阐明虚拟现实建模语言ＶＲＭＬ在未来生活中必将得到多样化的应用。

VRML AND ITS APPLICATION IN THE DISTANCE LEARNING SYSTEM OF MULTIMEDIA

The virtual reality was a very important sub ject in nowadays world,and VRML,as a very important exploiter-tool,is widely use d in many social scopes.The characteristics and current situation of the Virtual Reality Technique were introduced,and the concept,function and application scop e of VRML were stated.Based on this,VRML's application approach and method,in th e distance learning system of mutimedia,were discoursed upon;By means of interpo lators,eyeshot cartoon and three-dimensional cartoon,a practical dynamic modelin g example was designed.All of these reified the abstract teaching contents in the distance learning procedure,and clarified further that VRML would be applied variously in future life.
