Hi Pilou,
I've made two illustrations which might help you to understand what extraodinary faces is.

A vertex surrounded by three (1) or more than four (3) faces is called extraordinary vertex. And a vertex surrounded by four faces (2) is called ordinary.

If one or more vertex of a face is extraordinary, this face is called extraordinary too.


My script can load meshes with following types of polygons:

A - Ordinary quads ( 4 ordinary vertices ) - full support, best quality
B - Extraordinary quads ( 1 or more extraordinary vertex ) full support, best quality
C - Ordinary triangles ( 3 ordinary vertices ) looks good, but sometimes an artifacts can be noticable,
D - Extraordinary triangles ( 1 or more extraordinary vertex ) doesn't support at all. produces noticable artifacts on all neighbour faces.
E - Polar triangles ( group of triangles with a common vertex, two other vertices of each triangle must be ordinary ) full support, best quality.

So, you should not use type C and type D polygons.

Seems there are some new concepts realized!

Trying to imagine if you get this down to the vertex level..

Looks like you're making great progress, Max! Can't wait to try those open surfaces!

Really amazing to see this in MOI - thanks again for all your efforts!

Hey Max,

Do you think it might be possible to have an option to crease open edges ?


In practice it should even be the 'default' behavior, but I'm probably biased by Modo default settings.

BWAAA!!! SOOOO AWESOME Max! :-) ..oh, the evil plans are a conjurin'

I think PaQ's suggestion would make a lot of sense as a 'default'. Having an option to crease other (non-outer) edges would be the icing on the cake, if possible ;-)

Hi guys!

archetype
>>Can't wait to try those open surfaces!
Next weekend, I hope. Maybe earlier, maybe later :)

>>Having an option to crease other (non-outer) edges would be the icing on the cake, if possible ;-)
It's possible, I have it in the plans.

PaQ
>>Do you think it might be possible to have an option to crease open edges ?
Yes. I've wrote this script block yesterday.

Woah! Sweet!! Need to create a tutorial on *that* version!

Thank you :)
The work is going on successfully.
I need from two to five days to finish it. In fact I can do it during one evening, but I'm busy at work (as always) :)

Thickness possible or problematic for the last example?

Beta8
Added: open surfaces support

This version can be unstable. I need to optimize it, fix a lot of bugs, surface issues e.t.c.
Updated version will be soon.

The shell command can't process this shape.

Very funny scene! :)

And bravo for the task even some little glitches are maybe persisting!
