Just made some work and got this results first is original polygonal model, second is from T-Spline third from Max last beta.
T-Spline makes even less surfaces than on original but Max's script much more. Looks like a lot of geometry optimization must be done.

>Looks like a lot of geometry optimization must be done.
As I wrote before, it's just a first part of the script. The second phase is stiching surfaces with ordinary edges.
btw, can you check number of control point in t-spline model.

Bonus script :) Subdiv Classic..
I wrote this script few months ago for testing purposes.
It produces subdivided polygonal surfaces using classical Catmull-Clark algorithm.

Hi Max,

Thanks a lot for the last update, I'm really impressed by the result (and I can be very anal with that kind of stuff :)) ... I have the impression that poles area are looking even better than what I've seen
with Npower sub-d Nurbs Oo ... the overall shape is much better now too !

EDIT

The last .obj loader works much better, but well ... it still fails with a lot of my testing models (some sds cage model topology can be very distorted, with extreme non-planar quads).
Wish I could start to promote your converter with some famous models from the modo library (like the hypo, or the old man that npower also use for their own promotional material).

Maybe Michael can give you some advice in that area ?, he should know lots of stuff about file format ... because the converter itself is really amazing !

I hope the surface optimization will not change anything about the overall continuity quality !

So just to compare,

Hi Max,

Here's the oldman model already imported in MoI.
Looks like the geometry is ok (I had to join all surfaces in Moi, every faces were splitted after the import).

However the Beta5 don't seems to like it ... the object and the interface just vanish after few second.

Hi,
I've tested the Oldman on Mac OS X 10.10.2 and MoI V3.
1• open the Oldman.3dm
2• select the solid object
3• use Tab and type : _Subdiv_beta5
Result : object and subdivision panel disappears and have an empty vue.
Thanks

Hi PaQ,

Thank you. I hope it will be better :)

>>The last .obj loader works much better, but well ... it still fails with a lot of my testing models
Please send me testing models. It can help me improve my scripts.

>>I had to join all surfaces in Moi, every faces were splitted after the import
It's ok. Automatic join function enabled only for simple models (<1000 polygons).

>>However the Beta5 don't seems to like it ... the object and the interface just vanish after few second.
I know about this. This happens if there are gaps between the vertices of adjacent polygons.
Yesterday I rewrote loadMesh function. Now it works much better.
Wait for the beta6 today evening.
