Beta9 update. Fixed bug with polar triangles with open edges.

>>Can you put something on each start lines code (or before each line) where there is something to translate ?
When I write a complex script I always use a lot of comments. And I delete them automatically before publishing.
So it's not a good idea for me to mark text lines with comments. I'll think what I can do.

Gave it a pretty good workout Max... Seems to always work well for how I was using it!

Did some fooling around with using SubDivClassic as a means to "un-subdiv" the parts... Seemed a way to "kindof" revert, but with shrinkage...

Wondering if the "shrinkage" is something that is more or less a known factor, or is it more arbitrary with different geometries?

I didn't want to push too deep into your future plans with the tool.....

<< So it's not a good idea for me to mark text lines with comments. I'll think what I can do.

In my Text editor (NotePad ++) some word to translate are automaticaly in "Bold" but that not explore all! ;)
So maybe number line, color line, extra color word, ...

Just a question :
In your example, what is the command to directly split surfaces of the solid

is OK to use Separate ?

Also :
It will be great if Subdiv command wasn't destructive like Subdivision Surface in C4D ?

thanks a lot Max !

<< In your example, what is the command to directly split surfaces of the solid

Maybe Select Face(s): Edit / Separate
Select All
Call _subdiv_beta9
And if you subdivide again the result you have a funny rugby ball! ;) (Not shown following)

Hi Max.


That last post gave me an idea. Love this script. I have already donated some money but plan to give more in the future, Thanks so much. I am teaching 1st year London university students - Moi and Rhino. I think they will love this. My quick "Eames" chair.

This "shrink factor" depends on many parameters, and may varies from vertex to vertex. It will not be easy task to revert subdivided shape to its original state.
I'll try to find information about it tomorrow.

I will think about built-in multilanguage support.

Yes. This is the best way. I use it too.

Thank you very much! I'm happy that my scripts is useful for you :)

I thought this paper might be of interest:

Conversion of trimmed NURBS surfaces to Catmull–Clark subdivision surfaces.

Hello all

I'm sorry but how do I install this script?
Were do I place the 2 files?

I'm on mac.

Thanks

Hi Paulo,

I've just now added an answer to this in the FAQ section of the wiki, please check it out here:

Hi all,

I've got some pretty simple solids set up and constantly get an unsupported polygon pop up - am I not understanding a crucial concept?

Cheers,

- Rich

This mean, face polygon has more than 4 sides
Make it 4 sided, (only 3 or 4 sides supported)

Ah okay great thanks for that

- Rich

you are really the master of great scripts.
accidently found this...
a while ago i was looking for a way to further modify OBJ files.
this is the only solution i found so far.
(and MoI makes it really easy to re-model the surface parts where needed.)

Hey Max,

I'm a huge fan of your scripts and just now work on a design that requires the translation from Subdivision Surfaces to NURBS.

I have one problem though:
Everything works great as long as only two edges meet to build a sharp edge, but in my model I have several places where more edges meet and I wonder if it's possible to solve that somehow?
Here is my Model in Softimage XSI with hard edges applied (the blue ones):




And this is the result in MoI with your script:



I probably could remodel all those edges by hand, but they are many and I wonder if you would have an idea how to deal with it automagically ;-)

If I preserve corners I get rather weird results that are not usable.
It basically would need to keep the rounding but make the corners sharp only where several cuts/corners meet.

Thank you VERY MUCH!!!!

Cheers,

Tom

Thought some more on how this could be implemented:
If recognising the cross-points automatically is a problem, maybe we could select the points we want to stay sharp before we apply the script?
But I guess you would still need to somehow pick up the continuity between the parts...

BTW. My illustration above from MoI contains some selection errors, in both cases there would be four hard lines that meet in one point if it would be the same as in XSI, but I also have corners where three hard edges meet.

If there is anything I can do to help, please let me know.

Cheers,

Tom

Another question:
I checked for a while now, but seem to be unable in MoI to separate an edge.
How would I go about separating edges that are not separatable by a polygon selection?
Like splitting one edge in a ring of polygons? Can that be done at all?
Sorry if I miss something obvious here... ;-)
Otherwise I would have to try if it can be done by separating the polygon edge before import...

Cheers,

Tom

If you select all edges and then do a copy and paste you should have all edges as curves.
Is that o.k. for you?

Stefan
