摘　　要：地形是自然界的复杂形体,三维地形可视化是地理信息系统(GIS)和虚拟漫游的重要研究领域及其组成部分。三维地形可视化及其漫游在农业中有着广阔的应用背景,近年来越发受到人们的关注。为此,对OpenGL进行了简要的介绍,详细讨论了在OpenGL环境下,实现三维地形可视化的关键技术,并分析了三维地形的漫游方法。It is well know that the terrain is the most complicated object in nature. With the development of GIS technology, the 3D terrain visualization and VR（ Virtual Roam） are becoming one of the most import research areas today because the 3D terrain visualization and roam are a very important part of GIS. So 3D terrain visualization and roam has become increasingly interesting in recent years in agriculture because it has wide application backgrounds. This paper briefly describles OpenGL. We specific analyzed the key technology for 3D terrain visualization. At last, We also discussed the techniques of the roam of 3D terrain.
