I try to implement a Quad subdivision as published by Catmull and Clark. The mesh split step works fine so far - but the step which should set the positions of the old vertices and the "edge"-vertices not. What I don't understand is how these new positions should be calculated. I also wasn't able to find anything well explained on the web, like a pseudo code or a tutorial. thanks for any help on catmull-clark!

Do you want help with the algorithm, or do you want Catmull-Clark sources which might help you? If it's the former you'll have to provide us with A LOT more information.
