Hi Maciej, osg::State is probably not the best way to accumulate state for general CPU computation work as its totally geared around the rendering side.
What you are better off doing is creating a stack of osg::StateSet that you push/pop as you traverse the scene graph. When you encounter nodes/drawables that have a StateSet then clone the topmost StateSet of the stack and then do a StateSet::merge with the new one. I haven't actually implemented this myself before but this is at least how I'd go about it. Robert.
