Hi Michael, There is support in osg::State for setting a pointer to a bool that you can set to get the drawing traversal to finish without completing the dispatch of all the objects to be drawn. See the osg::State::setAbortRenderingPtr(bool*). You can can get the osg::State object for each GraphicsContext by context->getState(); You can get the list of active contexts from viewer.getContexts(Contexts&). See the include/osg/State, include/osg/GraphicsContext and include/osgViewer/Viewer headers for details of these methods.
I would add that is very old feature that is very rarely used, one I haven't looked at for nearly a decade so I really don't know whether it still works or not... Robert.
