OpenSceneGraph is an open source 3D engine, which is widely used in fields such as visual simulation, games, virtual reality, scientific computing, 3D reconstruction, geographic information, space exploration, petroleum and minerals. OSG is written in standard C++ and OpenGL, and can run on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris, HP-Ux, AIX, Android and FreeBSD operating systems. OSG has rich extensions in various industries, can seamlessly integrate with engines written in OpenGL, and use the most advanced graphics rendering technology in the world, so that every user can stand on the shoulders of giants.

In order to popularize the osgEarth technology, FreeSouth has recorded the basic components of osgEarth and part of the programming application for a wide range of enterprises, colleges and research institutes. Use the stable version 2.1.1 of osgEarth.
5) osgEarth download
osgEarth is a 3D digital earth engine library developed based on the 3D engine osg. On the basis of osg, it implements tile scheduling plugins, optional quadtree scheduling plugins, and more geographic data loading plugins (including GDAL, ogr, WMS, TMS) , VPB, filesystem, etc.), combined with a set of geographic projection conversion plug-ins, so that it can achieve efficient processing of loading and scheduling geographic data display on the three-dimensional earth, realizing a three-dimensional virtual earth.
