摘　　要：针对3维模型Internet发布时必然遇到的网络响应速度慢、响应时间长等问题,从提高3维建模效率、策略和压缩3维模型数据量入手,提出了一套适用于VRML虚拟校园场景的优化方案,并建立3维校园模型。同时,以武汉某高校南湖新校区为研究区域,建立该校区3维可视化校园管理系统,可快速、方便地实现校园信息的3维动态显示及空间查询等多种功能,为大学校园的信息化管理及小区物业管理等提供有益思路。It always has problems of network response time and response speed when the 3D model releases on the Internet.In order to solve the problems we focuse on improving the efficiency of 3D modeling and data compression,then proposed the design route and a kind of optimization scheme of the virtual campus.At the same time,we take Nanhu campus as the virtual space to implement the visualization information management system.Simultaneously the system may conveniently and flexible for three-dimensional dynamic display and spatial query.In addition,an optimization program of virtual campus based on VRML is presented in order to study and explores the virtual reality technology to provide the beneficial mentality in the hypothesized campus demonstration domain application.
