Subd general question

[pnoland]

Subdivision is an algorithm(s) used by polygonal modeling applications to smooth models. Rendering applications use them at render time. There's a few different types but the most common is catmul-clark which is what you'll fine Silo, Hex, Modo, Maya...etc using. Google be thy friend.

Uh...i'm asking here, not in google.
Thats not really anwers anything.

Any modelling paradigm that adaptively subdivides a polygonal mesh using the catmull-clark, sabin algorithm or variation of there, to produce a mesh, that is parametrically smoother and consists of quads, i.e two triangle faces.

Max has its mesh smooth modifer and its is Nurms algorithm (non-uniform-rational-meshsmooth) which is a variation of pixars methodoly.

Maya and soft both have subdivision surface modellers - im not sure what algorithm they use. Wings, nendo,silo,modo all are sub-d modelers. The very process of subdividing a polygon mesh to produce an adaptive smooth result is SubD plus the ability to step through iterations of the subdivision.

I did not use google.

Have a read here, there is a very awesome section on Subd http://www.subdivisionmodeling.com/wiki/tiki-index.php?page=About+sub-division+polygonal+modeling

Uh... he gave a reply and suggested you google for info as well, which wouldn't hurt.
best thing to do next to google:
http://en.wikipedia.org/wiki/Special:Search?search=subdivision+surfaces&go=Go

some inaccuracies here and there in some of those definitions, but I doubt you'll notice the most subtle ones yet. top 5 articles would be an informative read.
