OpenSceneGraph

The OpenSceneGraph is an OpenSource, cross-platform graphics toolkit for the development of high-performance graphics applications such as flight simulators, games, virtual reality and scientific visualization.

It is based around the concept of a SceneGraph, providing an object-oriented framework on top of OpenGL. This frees the developer from implementing and optimizing low-level graphics calls and provides many additional utilities for rapid development of graphics applications.

Written entirely in Standard C++ and OpenGL it runs on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris, HP-Ux, AIX and FreeBSD operating systems.

The official OpenSceneGraph homepage is at [1 ]

A good introduction to OSG is the Quick Start Guide [2 ]

Starting with version 0.4.1, Tcl3D provides a wrapper of OpenSceneGraph 2.8.2. It also has some demonstration programs [3 ] using the OpenSceneGraph library.
