Call for examples Subd to Nurbs

[theoutside (Kyle Houchens)]

We are continually working on refining SubD tools, and one in particular is on our desk, conversion from subd to nurbs-

we are interested in examples you can share of subd to nurbs conversion (please include the subd and the nurbs it converted to)

we are interested in examples where the packing does not do what you want, or could be improved.

Also any tsplines users who have examples where the conversion result is “better” for your uses, we’d like to see those as well.

all files here need to be publicly shareable, or you can use our uploader if the files need to stay confidential

Hi Kyle, this is an area of deep interest for us. We convert a lot for prototyping and also for release geometry. I’ll ask @jsantocono to grab some examples from our team. We’ll make a private message for this since it’s all client/confidential work. Let me know who should we invite to it besides you.

Thx,

G

I was hoping you’d bite here-

@dalelear is going to be the point person on this-

[sgreenawalt (Sky G)]

Ohhhhmygod I miss @jsantocono! What a blast from the past. What a great guy.

[gustojunk (Gustavo Fontana)]

This is very complicated stuff that requires full dedication. I suggest your team sends Dr. Lear to our Fresco South studio to work on this issue with my team, in person. We can stop by and visit to check on progress.

right?! the BEST!!

[theoutside (Kyle Houchens)]

we’ll send him, but you’ll have to feed him and keep his cocktail glass full…he is semi retired you know. after all.

(which proves even half retired, he’s still smarter than all of us…)

[gustojunk (Gustavo Fontana)]

Wining and dining important people is one of my fields of expertise. You might have to join to keep him at least half productive.

In all seriousness, a work week together will be very useful for all of us. It’s been too long since we did it last.

Dear @theoutside
I have 3 low hanging fruits / wishes for _toNurbs

• Output on current Layer (not the layer of initial SubD)
• replace planar Surfaces with a prober trimmed planar Nurbs-Surface ( and do not use / generate Surfaces with degenerated Vertices / Corners, as the attached example shows.)
• Feedback the Deviation close to the Star-Point / extraordanary vertices

Attached file and follow screenshot shows them:
(planar surface removed, Polysurface capped,
Deviation measured with pointDeviation and Feedback with dots…

I think it makes a huge difference to have some absolut feedback on the deviation, and not only staring at bumpy zebra stripes…
