Demeter is a cross-platform C++ library that renders 3D terrains using OpenGL/OSG,可以参考它的官方网站http://demeter.sourceforge.net/
dmeter的开发资料实在有些少,像我初次接触OSG和开源GIS并在此基础上二次开发出3D接口的初学者来说一时不知怎么上手,只能慢慢的看代码了...
官网上介绍Demeter的应用有Games Simulations Civil Engineering Construction Visualization Petroleum/Mineral Exploration Any application that needs to show 3D terrains to the user
至于说达到工业级,我想是没问题的。
