基于VRML仿真教学系统的设计探析

A Study of Simulation Teaching System Design Based on VRML

虚拟仿真技术的不断发展快速推动了多媒体信息化教学由传统的二维平面展示逐渐向三维立体人机交互设计转化,构建具有良好人机对话功能的网络虚拟教学环境,可以有效激发学生的自主想象能力,形成创新性思维。VRML是虚拟仿真最为核心的技术之一,通过Active X实现对系统各功能模块的分析与设计,并借助Java等网络技术将学生的交互行为引入到虚拟教学WEB体系中,是提高虚拟教学软件应用开发效率的重要内容,也为构建符合现代教育技术理念的WEB虚拟仿真教学平台提供技术支撑。

The continuous development of virtual simulation technology has driven multimedia information teaching to evolve fi＇om the traditional two-dimensional display to three-dimensional human-computer interaction design. A network virtual teaching environment with good man-machine dialogue function can effectively stimulate students＇ imagination and innovation. VRML is one of the core technologies of virtual simulation. To increase the efficiency of developing and applying virtual simulation teaching soft- ware,it＇s important to carry out researches on how to use VRML digital modeling and perception technology to construct the overall framework of virtual teaching platforna, as well as to analyze and design the functional modules of the system through ActiveX, and introduce students＇ interactive behavior into the Virtual Teaching WEB System with the help of Java and other network technolo- gies. And this can also provide technical and theoretical support for the construction of WEB virtual teaching platfoma in accord- ance with modern educational technology concept.
