基于VRML构建室内虚拟环境的设计与实现

虚拟现实技术是目前国内外计算机应用研究的热点,其实时的三维空间表现力和逼真的沉浸感,将极大地推动计算机仿真技术的发展。该文详述了虚拟现实技术的主要特征及其应用,并介绍了虚拟现实建模语言VRML的基本格式和特点,讨论了基于VRML构建室内虚拟环境的常用技术。最后,利用支持VRML的3DSMAX软件实现了三维复杂物体建模,通过Java/Java Script实现了用户与室内虚拟环境之间的动态交互。

Design and Implement on Building the Virtual Environment Inside House Based on VRML

Virtual Reality technique is the attractive domain for computer application research all over the world, its real- time three dimensional expressive force and realistic immersion will greatly improve the computer simulation technique. This paper details the main characters and application of Virtual Reality technique, and introduces the basic format and characters of Virtual Reality Model- ing Language. the frequently used technique in building the virtual environment inside house based on VRML is discussed . At last, modeling on the three dimensional complicated object can be realized based on 3DS MAX software which support VRML, and dynam- ic interaction between user and virtual environment inside house can be accomplished by Java/JavaScript.
