Cull and Draw are separate and for the same frame always done in the order Cull then Draw. Draw contains all pre rendering, main rendering and post rendering stages. If there are multiple Camera's on a GraphicsContext/Window then the Cull and Draw for the different Camera's can be interleaved, depending on the threading model, but always for a single Camera the cull traversal of it's subgraph is always done before the rendering for that subgraph. This has to happen this way as it's the cull traversal that decides what goes into a draw traversal.

[osg-users] camera pre-render and culling order
Hi Community, anyone knows what is the order of the camera pre-render and the cull traversal in a frame? Thanks a bunch as always!
