Subject: What subdivision scheme does Poser's "polygon smoothing" use?

Hi folks,

I've tried various combinations of "Reyes" and "Vortex" with "smoothing", "subdivision" etc, but couldn't find any concrete information on what's actually going on. Is it a trade secret?

Basically what I'd like to do is the following: I have a ca. 9000 poly figure that renders nicely in Poser when I subdivide it once in Wings. Subdividing in this case means SubD a.k.a. Catmull-Clark. Poser's Firefly renderer does something different, and meshes that work well in SubD don't necessarily in Poser. Now fixing this while working in a SubD modeler is obviously a bit tricky, but if I knew the actual algorithm, I could try to reverse it, starting from the higher res figure and thus create a modified version of my original figure that would be closer to the higher res one after one subdivision step in Poser. So, presumably, it would render better and look smoother.

I hope I made myself halfway clear. Anyway, any info on how the subdivision works?

Cheers,
Olaf
