Hi Max,

First thank you a lot for all the effort you did on this polygonal converter.
I have no idea of the complexity to write something like that, but I just want to point a general 'smoothing' problem with the method you are using. (and I'm not talking about surface continuity)

In the image :



A ) Max Sub-d : Low Quality
B ) Max Sub-d : High Quality
C ) Npower SubD-Nurbs.

My concern here is the wobble effect from the version B (Max Sub-d : High Quality).
This wobble effect is also visible on object silhouette. I know that I shouldn't compare your script to
a commercial 500$ product, but I'm wondering if it's something that might be improve in the future ?

In other words, while you manage to keep continuity between patches, it seems the side effect is an overall shape/silhouette deformation. It's something very obvious for polygonal surface subdivision people, used to see very smooth surface transition and ultra smooth overall silhouette. (catmull-clark)

Thanks.
