Generation of a Chebyshev net on a surface

I’d like to share my GH Def / Python code for generating a Chebychev net over a given surface following the algorithm by Popov[1]. A Chebychev net can be seen as a quad mesh with all edges being the same length. The only things that change are the internal angles.

It’s my first time scripting more than a couple of lines, any comments on how to improve the (probably inefficient) code would be most welcome.

Open questions

  1. How to pick the best starting point and the two vectors to allow coverage of the most surface
  2. How to stitch the mesh if the given surface is closed
  3. On a practical side, how do I make this into a component?
