I also spent a bit of time reading http://people.debian.org/~walters/descriptions.html for inspiration, before coming up with this. I do not feel 100% happy with it yet (I'm trying to do a proper job of it this time), and will appreciate further feedback: Description: Scene Graph graphics development library for C++/OpenGL In a Scene Graph, the world is broken down into a hierarchy of nodes representing either spatial groupings of objects, settings of the position of objects, animations of objects, or definitions of logical relationships between objects such as those to manage the various states of a traffic light. . The OpenSceneGraph supports various culling techniques, LOD nodes, state sorting, vertex arrays and display lists as part of the core scene graph. It has loaders for various common formats, including 3DS, FLT, and PFB. . The libopenscenegraph-demos package contains a scene graph viewer and various other demos of what OpenSceneGraph can do. There is quite a nice description of what a scene graph is and can do included with the source. Strange that I don't find it available on the official web site. (At least its not trivial to find...) Take a look at http://people.debian.org/~hvdm/introduction.html - 'scuse I didn't bother to upload images, etc. > That it is a "graphics development library" tells me nothing. Just spit > it out!

Do you think I've touched on the more important parts now? With your background it is likely you will have a better idea of what is important for the description...
