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!

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

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 :)

Thanks :o

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...

http://moiscript.weebly.com/uploads/3/9/3/8/3938813/pm3d_dog_1.obj quadrangles 8 000
http://moiscript.weebly.com/uploads/3/9/3/8/3938813/pm3d_gear3d.obj triangles 3 300

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.

Cool
Thx for the infos and tips and tricks!

---

This is great! Thanks Max!

---

Fantastic! You da man, Max, many thanks!

Sweet baby jesus this is powerful stuff. Max, I can't begin to tell you how thankful I am that you've implemented this and shared with the community.

While I only started a year or so ago with MOI as a step from STEP to FBX conversion, MOI has become such an invaluable tool that I've more or less gone from Maya polygon modelling to MOI parametric modelling* after nearly 15 years of using Maya. This addition feels like the last missing link between the two. Subdivision sketching can now be brought into MOI for finalizing.

Thank you, thank you, and thank you again.

*Yes, MOI's THAT good.

Same here, Rico. 14 years of 3ds Max (1998-2012), then I moved to Blender 3D (which is still my preferred 3D all-rounder), and not long after that MoI entered my life and stole my heart. ㋡

The only thing I really missed in MoI was the powerful branching of polygon subdivision modeling, but Max built an interesting bridge to that now.

Don't forget ExplodeMove after subdivide for cool possibilities!

---

Pilou, it looks great :)


P.S. Small update (Unsupported polygons stays selected)

---

Cool! ;)
