Yep exactly that would have been my second question. For a lot of multi
pass techniques you have to influence the traversing / drawing order.

Hmm hard to tell if you look at scenegraphs most of them already are
dead. Performer is the only one besides Java3D which I would call alive.
And OpenSG is far from thinking up stuff like this. Multipass stuff just
became popular arround beginning of 96/97 when common cg hardware was
finally powerful enough. But a lot scengraphs are older than this
time and already disappeared again. But on the other hand I haven't
searched for research papers on this matter yet so you could be right.
