基于ArcGIS Engine的三维校园系统的设计与实现

Design and Implementation of Three-dimensional Campus System Based on ArcGIS Engine

三维可视化是数字校园的高级技术特征之一,是实现虚拟校园空间的必然要求。基于Arc-GIS Engine,构建了成都信息工程学院的校园三维地理信息系统,把地理信息系统的空间模型移植入虚拟现实的三维世界,实现了校园的三维模拟,显示了校园的基本地物特征,并具有三维飞行漫游功能;允许用户进行简单的信息查询等功能,满足用户对三维视景实时动态的可视化要求。

Three- dimensional visualization is the number of advanced technical features of the campus of one of Virtual Campus is the realization of the inevitable requirement of space. Based on AreGIS Engine .Three- dimensional Geographic Information System campus （Campus3D） is to establish a campus of three- dimensional display query GIS systems, virtual reality in geographic information systems in real- time dynamic operation of the three- dimensional works, the geographic information system model of transplantation into the space of three- dimensional virtual reality world, Dynamic real- time three- dimensional simulation of the campus, showing the airport campus characteristics of the basic features and a three- dimensional flight roaming;allows users to carry out simple information.
