军事地图等高线的三维地形建模与实现

Method for Generating 3D Relief Maps Based on Military Map Contour

采用Delaunay三角网进行三维建模，用插值算法重建数字地面模型，用OpenGL进行三维显示来生成三维地形图。结合开发实例分析每一个步骤及相应算法，并给出所生成的三维地形图实例。

This paper introduces a method of generating 3D images using contour. It presents the conception and one of the generation algorithms of Delaunay triangulation, rebuilds the digital terrain model and vision 3D images with OpenGL. It gives each process and its algorithm using OpenGL with the Visual C ＋ ＋ as a developing tool.
