三维虚拟校园漫游系统的设计与实现

Design and Implementation of 3D Virtual College Roaming System

虚拟现实技术是计算机图形学研究和应用的热点,尤其是随着近年来计算机硬件的飞速发展,以及人们对虚拟现实的要求与日剧增,虚拟技术得到了飞速发展,应用背景也越来越广阔。介绍了基于Ogre与CEGUI三维校园实时漫游交互系统的设计与实现流程,涵盖了:模型的制作;Ogre3D专用素材的导出,各素材的介绍及之间的引用关系;利用得到的素材文件组织场景,其中深入介绍了Ogre3D采用的八叉树场景管理器工作机理;如何添加实时交互;如何利用CEGUI制作系统界面等。

Virtual reality is a research focus of computer graphics.With rapid development of computer hardware in recent years and requirements for virtual reality increasing day by day,technology of virtual reality develops quickly and applies in more and more areas.Process of design and implementation for three dimensional colleges real-time interaction system based on Orge and CEGUI is introduced,including model making,special source material exporting for Orge3D,source material introducing,scenario organizing based on available source material.Then working principle of scenario management based on octree in Orge3D is dis cussed in detail.How to add real-time interaction and how to make system interface based on CEGUI are also illustrated.
