It is well known that the topography is the most complicated object in nature. With the development of GIS technology, the 3D rendering of topography is becoming one of the most important research areas today because the 3D digital topography is a very important part of GIS. At the same time, 3D digital topography is also a key technology of VR(Virtual Reality). However, it is a difficult task to bring this key technology into effect because large quantities of data have to be coped with. These data mainly include data of topography and data of topographic surface features. There is no doubt that creating a real-time, interactive, vivid topographic environment using these spatial geographic data in computer is a very complicated work. Fortunately, with the development of computer technology, we can easily draw it in common computer with OpenGL. In this paper, we briefly discussed the technology of drawing 3D graphics and the solid view of digital topography as well as the mechanism and procedure of real displaying of 3D topography. Using this technology, we can easily render a 3D digital topography in a common computer. We also discussed two methods of realizing the dynamic view of topography, one is the viewpoint fixing with object-point moving. In fact, in many cases, in order to better understand the topography, we need to observe the 3D digital model along a selected routing. So we can use another method of dynamic view, that is object-point fixing with viewpoint moving. A specific example of drawing the 3D digital topography using the previously method is given.

地形是自然界的复杂形体,地形三维显示技术是地理信息系统(GIS)的重要研究领域及其组成部分。同时,地形的三维实时显示也是虚拟现实(VR)的一项关键技术,而虚拟地形环境面临的是巨量地形数据和地面特征数据。利用这些地理空间数据建立一个逼真、实时、可交互的地形环境是一项复杂的工作。本文介绍了OpenGL的特点及OpenGL图形绘制的基本技术在OpenGL环境下,三维地形实时绘制显示的机制及一般过程。探讨了OpenGL立体图形动态显示的两种主要方式,即:视点固定目标移动和目标固定视点移动。同时给出了具体的绘制实例。
