文档介绍：摘要
虚拟现实(Virtual Reality)技术是用现代计算机技术创建的一个酷似客观环境又超越客观时空、既能沉浸又能驾驭的和谐人机环境。虚拟校园是在计算机环境中,利用虚拟现实技术再现校园的景观,来访者足不出户就可以进入到虚拟的校园之中访问漫游,尽情领略校园的文化风情。
本文研究了虚拟现实技术,特别是虚拟现实在数字化校园建设中的国内外的先进理论,以此为基础深入探究了虚拟校园的基本要素、基本特征以及虚拟校园的软、硬件实现架构,同时也对当前比较流行的几种桌面虚拟现实技术做了对比研究。
结合xxxx大学的开发与建设,本文用3dsMax等软件开发了虚拟校园的三维模型,使用Inline节点来统一整合场景模型,将高精度建模与低精度建模有机结合,保证视觉效果及其浏览速度;利用JavaScript与导航、路由等节点相结合实现自动漫游、交互漫游。
关键词:虚拟现实,虚拟校园,VRML,JavaScript, 三维建模
Abstract
Virtual Reality technology is the man-machine environment which is created by the puter environment is exactly like the objective environment, but exceeds the objective space- both call immerse in it and control the campus is the use of virtual reality technology to reappearance campus of the landscape in puter can get into the virtual campus, enjoy the campus cultural as much as they like never to leave their home.
The paper introduced virtual Reality synoptically, especially the domestic and foreign advanced theory of virtual reality in digital campus on this,to probe into the basic elements,basic characteristics,the realization of hardware and software architecture of virtual campus,and parative studied several popular desktop virtual reality technology.
Combining the virtual campus development and construction of Changzhou institute of light industry technology, I developed virtual campus three-dimensional models with 3dsMax,VRML etc software,and used Inline node to integrate the scene integrated high precision and low precision model building call ensure visual effect and browse bination of JavaScript and navigation, route etc node,we can achieve automatic navigation and interactive roaming.
