Hi,

I have to synchronize two Instances of Performer running on two Computers.
I want these two Instances to draw a frame nearly at the same time.

My Idea to solve this problem, is to use a DRAW callback function such as
this one:

void DrawFunc(pfChannel *chan, void *data) {

	thisComputerIsReadyToDraw();	//to tell the other
					//Computer I'm ready

	while(otherComputerIsNotAtThisPoint()){
		//wait wait wait
	}

	pfDraw();

}

Is this a appropriate method?

Or is it possible to modify the pfDraw() in a way, that the synchronisation takes effect shortly before swapping the buffers? For this purpose I would have to know, what pfDraw() does in detail.

tia,
Klaus

pfGreetings,

FYI, I've just committed some sample code donated by the Performer
community.  Special thanks go to Scott A. Friedman for the pfgtk example
and Bram Stolk for the Python wrapper for Performer (pyper).  It's great
to see this kind of involvment and I look forward to future submissions.
