摘要
目前大部分查询路径的系统都是基于二维的,GoogleEarth的出现将路径查询系统引入到了三维的世界,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习惯。本文介绍利用VC++6．0、MapObjects和OpenGL来实现一个能虚拟显示行走过程的三维空间查询系统,从而对OpenGL在GIS软件中的应用进行了探讨。
Most of existing path searching system are based on 2D. With GoogleEarth＇s coming into being, path searching system is introduced into 3D world. But GoogleEarth displays the path in a way of overlooking, which doesn＇t in accordance with the visual effect of people＇s general travel course. This paper introduces a 3D spatial searching system that can virtually display people＇s travel course in VC＋＋6.0, MapObjects and OpenGL. The application of OpenGL in GIS software is discussed in this paper at the same time.
