I know I've asked similar questions before but now I'm looking to use OSG to
perform temporal averaging differently than I've asked before.
Is there a way to perform an "update", "cull" and "draw" on only a sub part of
the scene graph?
I want to average (say) 16 successive frames. For example,frames 1-16 should be
average together and the final average being sent to the frame buffer. Same for
frames 17-32, 33-48, etc.
To do this, I assume I'll need 16 "cameras" all looking at the same scene
graph. The first 15 would be rendering to a texture which is passed to the next
camera while the last simply renders to frame buffer. Since I want to "move"
the players slightly between each camera node, how would I do this? Normally,
an update callback would be called on the entire scene graph but I'll have a
"shared" scene graph so I don't think this will work.
Any words of advice?
Thanks,
Paul P.
