OpenSceneGraph

OpenSceneGraph is an open source scene graph system (SG ), which is used as real- time graphics applications such as FlightGear.

OpenSceneGraph is written in C , OpenGL used as a basis for 3D graphics and runs on a variety of operating systems, including Microsoft Windows, Mac OS X, Linux, IRIX, Solaris and FreeBSD.

Although it bears a name similar to the scene graph system OpenSG and was started about the same time, there are two separate and independent projects.

The development of OpenSceneGraph started in 1998 by Don Burns. 1999 came Robert Osfield to do so. The project recorded no download rates and has no way to measure the number of active users. However, the number of subscribers to the OSG mailing list has grown to more than 1,500 readers in 2006.
