Take a given, irregular mesh, and reduce the facets.

Hi All,

I have a mesh, it can't be a nurbs surface, it's a given mesh - a model of an animal. It's coming from max, so the mesh is pretty intense, about 22000 faces. I want to abstract/simplify the form and give it much fewer number of panels.

What I've done so far is explode the mesh and find each face quads vertices and separated them by list item. What I'd like to do from that is select from within those list items maybe every 10th, 15th, 20th, or whatever point and make vastly simplified panels.

Subsets don't seem to be the tool to use, anyone have a smarter idea? Many thanks, John.

From the movie Primer:

Aaron: You know that story, about how NASA spent millions of dollars developing this pen that writes in Zero G? Did you ever read that?
Abe: Yeah.
Aaron: You know how the Russians solved the problem?
Abe: Yeah, they used a pencil.
Aaron: Right. A normal wooden pencil. It just seems like Philip takes the NASA route almost every time.

Thanks Ching!

No problem, glad I could help.

If you wanted to make this process automatic (if you had to do this do a bunch of the files), could you write Python Script in GH to perform the Rhino functions for you?

Cheers,

Rob.
