I can answer this question: see the haveApplied*() functions in osg::State. Of course, Robert's answer will be easier though :) I'm not sure what the best way to get the State is; you might try attaching a preDrawCallback to the viewer's Camera, or perhaps GraphicsContext::setState() (via viewer.getContexts()). > => using that technique, would I be able to cull / draw osg stuff in > separate threads (handled by the hosting engine) ? > > thanks in advance for any answer or tips... -- Bryan Thrall FlightSafety International [email protected] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
