This sounds like the idea of generating a set of NURBS or bicubic patches from a polygon mesh to me. It's sounds like a cool idea, though our NURBS don't support patches, of course.<br><br>Joe<br><br><div class="gmail_quote">

Hi devs,<br>
<br>
Below is a text I got from Claas Kuhnen, teacher Industrial Design in<br>
Michigan. I knew subsurf modeling would be discovered once as superior<br>
to Nurbs! :)<br>
<br>
What we probably need is to get good conversion code for Subsurf -><br>
Nurbs and back. Anyone?<br>
<br>
-------------------<br>
<br>
I recently saw that Catia from Dassault system incoporated Subdivision<br>
Surfaces into their workflow. It is fully treated as a parametric<br>
system, so NURBS surfaces are created on the fly based on the polygon<br>
mesh and the result can be trimed and further worked on.<br>
Some years ago AmapiPro 7.5 had NURBS subsurface smoothing included<br>
instead<br>
of only Catmull Clark.<br>
<br>
Here are some Catia movies showing you the integration.<br>

<br>
I thought you might know that this type of modeling is now finally<br>
becoming the hot topic at Industrial Design. Catia is around 30.000<br>
dollars and I assume that they have serious reasons for including it.<br>
