Hi Alberto
I just need to control when I flush the stack, to synchonise with the
threads. A Callback would flush the stack (and so modify the graph) at the
same time of the callbacks which traverse the graph... It is dangerous.
I would stop the threads, flush my stack, and notify the threads to

Hi Robert,
You said then you'll need to place a barrier in frame loop to half the
frame loop thread
I'm not sure to understand how I can do it, and what do you mean by half
the frame loop ??
Moreover, I need a stack, that will be re-used for an other way, so I think
I'll keep this idea. I

Hi Vincent,
The OSG designed around the model of single threaded update,
multi-thread cull-draw. If you have others threads beyond the main
frame loop thread that is want to do updates then you'll need to place
a barrier in frame loop to half the frame loop thread while you
operations run, then
