分布式三维虚拟校园的设计与实现
中文摘要
在充分考虑学校软硬件设备的基础上,本文将虚拟校园设计为五个层次,设置公
共平台、角色平台、群组平台以及辅助平台四个大类。细分为:用户、课程、班级、
社团、科研、娱乐、管理等模块。以虚拟校园环境为基础,由虚拟课堂、虚拟实验室、
虚拟图书馆、虚拟社区等四个功能构成。
在虚拟校园的制作环节中,挑选适用的数据采集方式及软件,采用不同的建模方
法进行建模,利用基本材质、位图贴图、复合材质完成模型材质的制作。采用了实例
技术、透明纹理映射技术、细节层次模型技术、烘焙纹理技术、法线贴图技术等优化
技术。
使用Virtools工具对各个虚拟场景进行构建,对其交互性进行优化:启用贴图Mip
功能、利用Hierarchy Manager来进行优化减少Culling的运算时间,合理使用灯光类型
并控制其数量,用Multires Texturing的Shader增强层次感。用行为动作模块将导入的
所有前期素材建立关联机制再与交互系统充分协调,实现虚拟校园的游览交互功能。

The research on design and realizing of distributed three
dimensional virtual campus
Abstract
Based on considering situation of soft and hard equipment, in this paper the structure of
virtual campus are classified five parts which in-cluding four flats and several blocks. The
virtual campus posed of virtual class, virtual laboratory, virtual library and virtual
community.
The paper selects many kinds of proper ways of data collection and software. We
construct model of virtual campus by different ways, such as texture mapping, multi texturing
and bitmap texturing etc. In process of pinup picture, I select severs practical technology, for
example case technology, transparent texture mapping, level of detail model, baking vein
technology and normal texturing technology.
In order to optimize interactive of virtual campus, I use Mip function, hierarchy
Manager which to reduce culling time, proper lighting system, Multires Texturing which to
increase stereovision of shader.
In order to realize interactive function of visit in virtual campus, the design use building
block which basing on use various of material .
Key Words: Digital campus, virtual reality, virtual campus
