Be sure to ask if you need more help.

Wow amazing!
I hope it wasn't too much trouble for you to do that.

Few more questions.

Is it possible to apply to a mesh or polysurface?
Are voronoid cells limited to only 5 cells or are we able 'randomize' them so maybe they have 3, 4 or 5 sides?

Lastly, is it possible to change the thickness of the webbing as in to have more emphasis on the thickness between the nodes?

Again thank you so much!

<I don't know very much about meshes so can't answer that.  I don't think my definition will work on a polysurface but there are probably other ways to develop a definition that will work.  Can you provide a poylsurface that would be representative of what you want to work with?>

<I don't know what determines the voronoi geometry so can't answer that...maybe try googling 'voronoi'>

Lastly, is it possible to change the thickness of the webbing as in to have more emphasis on the thickness between the nodes?

<This should be possible.  When I get some free time again I'll look at that.  Someone else may have already figured it out.>

Again thank you so much!

Hi Chris.I've attached the file. Pretty much I've shrink wrapped a form in Blender and imported it into Rhino, now I'd like to cover it in the pattern. The file is only an indicative surface. The final will get more complicated, just thought I'd send a basic one through to see how it goes first.

Also is there a way to generate similar pattern but maybe a triangular grid?

It's the same definition as before but I've internalized your surface or rather my rebuild of your surface.  I took one of the mesh surfaces you provided (check the Layer pane) and converted it to a nurbs surface in Rhino and then extracted the top and bottom edge curves.  I then rebuilt the edge curves to get two smooth degree-3 curves.  I then lofted them to get the surface to use in the definition.  As I said before I don't know much about meshes but they don't look like they would be easy to work with.  The key to using any mapping technique seems to be to have the smallest number of surfaces possible, a single surface being the ideal.

As in doing them manually? On the scale that I would like to do this on, it might be too time consuming. thanks for the thought.
