My Cheater Method to Mapping 3D Spheres / Polyhedra

I posted this over on LEDs Are Awesome a bit ago:

I am working on spherical project and found a really great resource online with 3D coordinate systems for all sorts of polyhedron.

The coordinates can be manually manipulated into an obj file, and then imported to Blender to arrange vertex indexes to match LED wiring order and exported back to an obj file.

That’s an interesting site - thanks for sharing.

This is super cool – I’m setting up a helmet for Burning Man where I was going to just “flatten” the hemisphere for the mapping, but I think this would work much better if I can play around with it!
