| 摘 要： | 论述军事地图的等高线生成三维地形图的一种实现方法。从等高线地形图中取得离散点高程数据，然后采用Delaunay三角网对离散高程数据点进行三维建模，用插值算法重建数字地面模型，采用OpenGL对所建模型进行三维图形生成和显示。结合实例开发分析每一个步骤及相应算法实现，并给出所生成的三维地形图实例。构建的三维地形符合等高线的规律，构建运行速度快，生成的立体图像逼真。

| Abstract: | This paper int roduces a method for generating 3D images using contour.The dispersed elevation data is gained from the military map contour.It presents the conception and one of generation algorithms of delaunay triangulation,rebuilds the digital terrain model and vision 3D images with OperGL.It gives each process and their algorithm using OpenGL with the Visual C++ as a developing tool.The rebuilded 3D relief maps fit the law of contour,rebuild quickly and that are distinctly and beautifully. |
