Hi Max,

Hope their will be a little 'donate' button somewhere so we can buy you a drink or something :)

Hi Max:

For the 2008 paper, ....Tri/Quad/Pent Facets, there is source code and a movie here:
http://www.cise.ufl.edu/research/SurfLab/pubs.shtml

There is an errata file with corrections for page 5 and 6 here:

There is a 2009 paper as well.

Wow. Really great stuff, Max! This looks like the ideal bridge between poly and NURBS modeling.

I'm wondering: how clean are the smooth surfaces that are generated, in terms of surface points amount when separated? It would be fantastic if the smoothed version of a model remains adjustable after the smoothing.

Also, models converted with T-Splines in Rhino have trouble managing vertex points with 5 edges (so-called star points), resulting in a visible surface continuity artifact where quad polygons meet at a star point. How does your script manage those?

Can't wait to have a go at this!

Thanks!

Metin

TSplines-like modeling in moi? That sounds incredibly useful. Thank you for your effort.
Max.

Here is the first public release of the subdiv script :)
In fact this is only a half of the script. It works correctly with ordinary and polar vertices only. But it still has some problems with extraordinary vertices in some cases. I'll finish the second half of the script in nearest future. There will be two methods of subdivision: fast and accurate. Here is an implementation of the fast mode only.

Usage:
Select one solid or group of solids. Run script.

P.S. Would like to thank everybody for support. Thank you!
The idea about a donate button is good. Maybe sometime, but not now :)

Hi Max, cool stuff! Looks like it is working well for valence=4 vertices currently.

How is a reasonable number of polys of an import obj file?

Try with these 2 ones separated from ZBrush with no result ;)

_importObj works fine
_subdiv_beta open for gear but...

And have you project for that or not ?



And this one ?
No caps in the result ! Does this normal ?

Frenchy,
""""""""""""""And this one ?

You can trim the top and bottom faces of this type of object:



The other one looks like something is greater than 5? Maybe look to have at the most a quad case....

Hey Frenchy,
Here's a trick for you. You can subdivide up your ngons to allow them to work....

Max,
I love that the objects points remain editable!

If you can figure out how to keep the original faces and smoothing attached, this will be a mind blower... Replacing hexagon for me.... essentially, "box modeling" in MoI..... :o

Hi Pilou

>>How is a reasonable number of polys of an import obj file?
100-200
I think this script will be more useful for subdivision modelling (like Siemens NX).

>>And have you project for that or not ? (Error: N>5)
As I said above, this script supports 3- 4- and 5-sided polygons only.

>>No caps in the result ! Does this normal?
Yes, it's normal. Pentagons isn't supported in fast mode.
