OSGAR extends OpenSceneGraph so that it will be suitable to be used for AR applications, by supporting transformations that have uncertainty associated with them. Building on the fundamental notion of uncertain transformation, OSGAR provides programmers with a range of facilities for querying and acting upon estimated registration error. The following are a sample of the kinds capabilities we are adding to the scene graph:
- Display a video stream as a background (Video AR)
- Detect artificial markers
- Connect to different sensors through a VRPN client
- Handle multiple sensors (combiners)
- Computer registration error estimates in real time

The code is pretty old at this point; what’s your use case? If you are just looking for an AR framework, there are many newer ones. Or are you specifically interested in some of OSGAR’s features?
