Draping with equilateral triangles / Creating a faceted textile

A while ago I mocked up a faceted textile for a photoshoot using 1,000+ laser-cut brass triangles, adhesive, and a felt backing. I want to revisit that concept again with a little more intent, maybe try to capture a specific form by laying it on top of a 3D printed or CNC routed base. I’m challenging myself to recreate this kind of structured surface in Grasshopper but I’d appreciate some guidance.



I’ve scoured through quite a few triangular meshing topics, and Mesh Machine gets pretty close, but that’s not accounting for the spacing and hinge-like movement between the triangles. I’m not sure remeshing is the right tool.

I’m curious if there were any similar topics I missed, or if anyone had an opinion on a direction. Is this something I could do with Kangaroo without crashing?

Thank you

This isn’t really a remeshing exercise, since the connectivity is regular and fixed.
You just need to enforce the length constraints and drape it over something, which can be quite straightforward. I’m confident there wouldn’t be any issue with crashing here!

That’s a lot of fun, thank you. I will post fab updates once I try it again.

I remember a few years ago some nice work from this artist with a wood veneer version of these crumpled equilateral textiles

Along a similar line, it made me think of some of the products from Wood-Skin:
