摘要
现有的大部分查询路径的系统都是基于2维的,GoogleEarth的出现将路径查询系统引入到了3维的世界,但GoogleEarth是以鸟瞰的方式向人们展示路径的,不符合人一般行走过程的视觉效果。本文介绍利用VC++6.0、M apOb jects和OpenGL来实现一个能虚拟显示行走过程的3维空间查询系统,从而对OpenGL在G IS软件中的应用进行了探讨。
The most of existing path searching system are based on 2D. With GoogleEarth＇s coming, path searching system is introduced to 3D world. But GoogleEarth displays path to people in a overlook way, which doesnt accord for people＇s going visual effect. This paper introduces a 3D spatial searching system that can virtual display going course in VC ＋ ＋ 6. 0, MapObjects and OpenGL. Thereby the authors discuss the application of OpenGL in GIS software.
