Hi, I guess my first question was too vague. Sorry about that. I am still trying to use transform feedback on an entire scene inside osg.
I have created a CustomDrawable class with a drawImplementation that can perform transform feedback on anything drawn inside it. I am now trying to draw the entire scene inside my drawImplementation using a node visitor to traverse the graph and locate and draw all of the drawables with transform feedback enabled. I do not understand the parameters of "void draw(osg::RenderInfo &renderInfo) const" function. Can you please explain what information RenderInfo contains? Is the RenderInfo different for each drawable or global for the scene? Is it possible to determine the RenderInfo of a drawable?
