Hello all I have a camera postdrawcallback, and I want to draw a little scene-subgraph manually. So lets say for my subgraph I have a osg::Node as an entry point. How can I call the drawImplementations of the objects inside this subgraph manually?
The reason for doing this is a post processing. I have quads with assigned textures that I want to draw in this postprocessing step. I know there is osgPPU but unfortunately it doesn't work with composite viewer so I decided to have my postpro implemented in the postdraw callback. So, how can I draw nodes manually? Regards Daniel
