摘要:随着"数字地球"概念的出现,构建一个可视化、数字化、虚拟化、网络化的巨大系统不仅是必要的而且是可行的.以Lidar点云数据为地形数据源文件,讨论了基于OpenGL的点云三维可视化表达,以此作为剪裁Lidar点云数据的依据.对视景裁剪及四叉树组织的Lidar数据生成了三维地形场景,并实现了场景的实时漫游.

3D visualization expression of the point cloud based on OpenGL
Abstract:With appearance of the concept "digital earth", it is feasible and obligatory to construct a huge, visual, digital information system.Based on Lidar point cloud data, which used for topographic data source, 3D visualization expression of the point cloud is dicussed through OpenGL.It crops the Lidar point cloud data on it.3D terrain scene is created by the Lidar point cloud data which was disposed, and the scene can roam real-time.
