Hi Bret, The osg::Camera has initial/pre/post and final callbacks that can be used for the purpose of adding extra calls. It's also possible to use an osg::GraphicsOperation and attach this directly to the osg::GraphicsContext (equivalent to Producer::RenderSurface).
I would have though the Haptic's wouldn't be directly to OpenGL though so you could probably run the calls from the main loop i.e. not need a valid OpenGL graphics context, or even run the thread in background thread. I'm not familiar with the hatpic library though so I could be heading off in the wrong direction.. Robert.
