osgRPi
This is a small project for using OpenSceneGraph with the RaspberryPi. It does not (currently) implement a fully-fledged osgViewer::GraphicsWindow object; it simply uses the EmbeddedWindow API.
Also included is the script I use to cross-compile OSG applications using CMake for the RaspberryPi, since building OSG ON the Pi would probably take longer than just rewriting a new scenegraph yourself. :)
Future Development
If you are interested in funding further refinement of OSG support on the RaspberryPi and Broadcom VideoCore device please contact us at AlphaPixel. This could be a really interesting, emerging market for dirt-cheap OpenGL/OSG visualization!
