摘　　要：地形是自然界最常见的景物之一,随着虚拟现实技术的发展,对于真实感三维地形的应用越来越广泛。为了进一步满足视景仿真中对具有实际地理特征地形的要求,本文提出了基于数字地形图的三维地形生成新方法。该方法使用的地形图数据成本低,利用地形图上的亮度信息恢复三维形状,获得了较好的效果,通过数据对比证明了该算法的有效性。Terrain is one of the most common scene in nature. The realistic 3D terrain is more and more widely used with the development of VR technology. In order to meet the requirement of practical geographical characteristics in visual simulation, this paper proposed a new method to generate 3D terrain based on the digital terrian map. The map used in this method has a low price. This method used the brightness of terrian map to recover the 3D shape. And the result is satisfactory. This paper also proved the effectiveness of the algorithm by data comparison.
