OpenSceneGraph 3.2.1 released
OpenSceneGraphis open source, real-time graphics middle-ware used by application developers in fields that range from visual simulation (flight, marine, vehicle, space simulator) to virtual and augmented reality, to medical and scientific visualisation, to education and games. OpenSceneGraph is written in Standard C++, taking advantage of the standard template library (STL) for containers. The software uses the scene graph approach to representing 3D worlds as a graph of node that logical and spatially group subgraphs for behaviour and high performance.
