此资料介绍的是：利用OpenGL实现三维地形可 视化,采用Delaunay三角化法得到地形采样点,并用已知数据对三角曲面进行插值加密,生成规则格网(GRID)数据结构的方法,可得到高度真实感的三维地形可视化效果。 -The data presented are: the use of OpenGL for three-dimensional terrain visualization, using Delaunay triangulation method to be terrain

基于等高线的三维重建地形，vc环境实现三角网格的划分-Based on the contour lines of the three-dimensional reconstruction of the terrain, vc environment to achieve the division of the triangular grid

给出三维点云的X,Y,Z坐标，重构出三维图像，其中用到了三角网格法和规则化坐标法。-Given 3D point cloud X, Y, Z coordinates, three-dimensional reconstructed images, which uses a triangular coordinate grid method and rules of law.
