OpenSceneGraph

OpenSceneGraph is an open source high performance 3D graphics toolkit, used by application developers in fields such as visual simulation, virtual reality, scientific visualization, games and modelling. It is implemented in C++ upon OpenGL, and forms the foundation of a number of Omegalib plugin modules, such as Cyclops. In some ways, OpenSceneGraph can be considered an open-source project inspired by sgi’s IRIS Performer.
