Extrude Mesh Faces In conjunction with a form-finding exercise in Kangaroo, I was searching for a way to render a single, closed mesh as if it were an inflatable form made of individual, stretchy panels – think soccer ball. Since I was already starting with a mesh, I needed something that could extrude and manipulate individual mesh faces normal to the face centroid with a certain degree of flexibility.
I couldn’t find much online, so I put together a super basic, simple grasshopper file. Aside from some of the typical drawbacks with using meshes in Rhino (which have actually become a lot more workable in Rhino 5), I think it’s reasonably clean.

Bucky was right I’ve used genetic algorithms for form finding with a previous project, and that time I was using a tenuous connection between catia, modeFrontier and Robot. Grasshopper.
