algorithmic modeling for Rhino

Inspired by Stefan Sechelmann's presentation at the recent AAG, I've been having a go at using Kangaroo to optimize for quasiisothermic meshes.
This is a discrete Costa Minimal Surface. All the quads are planar with tangent incircles.

I use a slightly different energy (which I'll write a post about soon), but to optimize towards the same condition.

Yeah! Awesome! Thanks for sharing!

Wow, this is awesome. Could you let me know where can I find references to understand the algorithm?

Yes, in theory this approach should work with many types of surface. The tricky part is initializing it with the right singularities though.

Comment by Behnood Eghbali on October 4, 2012 at 4:21pm

so you can create all types of minimal surfaces... this is really awesome ;)

Here's the model if anyone is interested:
