Surface Continuity checking in Maya

[Anonymous]

Hey Guys, 

i would like to know if there are any kind of tools/shading options in maya to check the surface continuity of your Nurbs Surfaces. 

A example would be the zebra stripes as in Alias or Rhino. 

It doesnt have to be zebra stripes since i am sure Maya does not have those. I am fine with any kind of diagnostic shading that checks the continuity of your surfaces. 

It would be awesome if someone could tell if such a thing exists!

Cheers!

Would the checkerboard texture work for you?

@pshwayka: i don´t think thats what he wants.

unfortunately maya doesn´t has it by default. but you can create something like a zebra quite easy.

it´s not excactly the same like the alias one but should be enough for a quick check.

wih similar methods you can also create other verions of the diagnostic in alias.

Hey Guys, 

first of all thanks a lot for your suggestions! And a big sorry for not responding sooner - usually i get a e mail if someone replies to my threads in other autodesk forums - i have that option on by default - but it seems that it did not work this time!

Sorry for the huge delay! I thought about this again today an remembered my thread!

Thanks again - i thought about doing it via the texture - the thing i was unsure about was if there is some underlying calculation going on in something like Alias - if that is not the case and its purely an applied texture that has a pattern on it that makes it easy to spot flaws than thats of course perfect to me. 

Sorry - i come originally from drawing and sketching cars so the whole 3D thing is pretty new to me!

Is there a lot happening with NURBS still? I mean from a development perspective? Most of the new improvements seem to be centered around the Modeling Toolkit. I like where both methods of modeling are right now - i just hope people dont forget about NURBS modeling - i really like it!

If you use Arnold you can also use a aiUtility shader set to 'Reflection Lines' color mode. It gives results like the attached image. Though it is not live in the viewport.

Yes, this comes really long after your post have been made, just for anyone who has googled this recently.

I made a quick tutorial on 3D modeling artifacts and like others who have replied I use a flow check map in the reflection slot to check my surface.

You can download a colorful flow map similar to the zebra map but only looks more cool 🙂 here: https://gum.co/jlvkd

and these are two articles, one on 3D modeling cars in polygons and why you need to test with a flow check map here: www.ebalstudios.com/blog/modeling-cars-polygons

And another on mo 3D modeling artifacts and it goes into the flow check map: www.ebalstudios.com/blog/3d-modeling-artifacts-flow-check-reflection-map
