No problem! I had not time to find it! :D
So the French one! ;) http://moiscript.weebly.com/subdivision.html

Finally, I implemented a new method for extraordinary faces. In fact, I don't like this method.. I would like to have ability to create surfaces with different control point weights using Javascript interface, but now it is not possible. Michael, could you make it in the next version of MoI? (it will not take too much time, because the engine perfectly supports them.)
But yesterday I found another way. :) I can generate a temporary STEP-file with surfaces descriptions,exactly as I need, and then import it back.
So, I don't need to split an extraordinary faces to parts anymore. :)

Other notes:
High quality switch has been removed. Now preview is always generated in the fast mode, and result - in quality mode.
Also I have removed "Show points" switch. Just double click on title to make points visible.
I still have rare problems with LoadMesh function. I'll check it later.
The script doesn't support opened surfaces and extraordinary triangles (excluding a polar triangles)

My volume above has not extraordinary faces ? (i must subdivise in triangles)
Or your next version will resolve this ?

---

I hope that open surfaces and extraordinary polys are a possibility someday... it would be neat to create organic shapes ending in clean and straight openings.
Great work Max! I'll play with this update soon.

---

Cool stuff Max, Thanks!

I ran it two times at S=50.

---

Thanks again Max!

Here's a sample to look at something I saw. You may chalk it up to "don't use it that way", or it may help you refine it for the future.

In the sample, if you manually enter a value a little larger, you can preview a kindof "harder edge" output (It starts to suck the walls in a little), but the "complete output" morphs from what is shown at the preview stage...

Steps. Try enter a value of 130,,, Note the preview looks fairly neat. Press done and look at result... (A value of 120 seems to give a result like the preview of 130, etc)

Anyway. Nice job again........

I spent a lot of time online looking at comma usage in javascript.

Is there a purpose of the comma after the curly braces: },

I'm guessing that such commas are ignored, and there to make the end of function statements clearer ?

Hi Max, great work!

Yes, I'd definitely like to add more direct access to all the various parts of curve and surface structure (control points, weights, knot vector, degree, etc...) to scripts in v4.

Yes, there are extraordinary faces in your model.
At this moment the script supports extraordinary quads only, not triangles.

>> Is there a purpose of the comma after the curly braces: },
The purpose of a comma separator is to delimit members in a list.
For example:

var obj = {
  a: 22,
  b: 33,
  c: function() {return this.a+this.b},
  d: function() {return this.a*this.b},
  e: function() {return this.a/this.b}
}

I'll try to make it in the nearest future. 1-2 months.

I remember about this. It's old bug of hq mode. I just had no time to fix it, but I hope I'll do it soon.
So, don't use it that way :) At least now. ;)

Michael Gibson
>> control points, weights, knot vector, degree, etc...
It will be great! Thank you.

Excellent job Max! Thank you.

... only SubD exercise + blend... extravagant "Caraffa Cuore" :-)




render in Octan has to be improved... some triangle artefacts appeared.

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.

THX for the detailed infos!

---

Beta8 will be soon ;)

---

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.
