摘要
本文介绍了研发虚拟林相三维可视化系统的技术流程与实现方法,该系统研发基于目前较流行的以Visual Studio C++开发组件调用OpenGL三维图形库的方法,自主研发出虚拟林相三维可视化系统。该系统按三角带组织DEM数据并读入VC,采用LOD、四叉树技术自主研发了标准真实DEM数据构建三维地形的导入引擎,实现了地形可视化以及一些基本功能。为还原真实的地形地貌,应用OpenGL中的纹理映射、光照、场景分割、反走样、八叉树、雾化等三维可视化特性,增强了三维可视化效果。
The article introduces some basic methods of making Virtual forest .At present, based on OpenGL which is the powerful 3D graphics library and developed by means of VC＋＋ in PC. Independent research and development makes a system of Virtual Forest 3D Visualization, makes use of OpenGL 3D visualized characteristic of texture, light, scene segmentation, anti-aliasing,Oc_tree,atomization and so on. So it restores the true topography, realizes the visual terrain and other basic functions.
