The osg::RenderInfo has high level info such as what is the current View being rendered and what the current Camera is. https://github.com/openscenegraph/OpenSceneGraph/blob/master/include/osg/RenderInfo The RenderInfo is passed to drawables during the draw traversal via: osg::Drawable::drawImplementation(osg::RenderInfo&) The CullVisitor also has a handle to the RenderInfo as well as various other useful state info: https://github.com/openscenegraph/OpenSceneGraph/blob/master/include/osgUtil/CullVisitor Robert
