Hello David. Glad you"ve answered.
I dont really know if the panels are really identical. The only fact that makes me think of that is an article in the detail magazine (an architectural german magazine) they explain that the panels are Tetragonal, Which means that they have a square base (a ; a) and a different height (c). So iI'm guessing that at least the panels are identical y the x & y axis. Otherwise as architect my self, I know that curved surface are very difficult to populate with a single panel solution, but is this solution that we all try to acheive. Anyway I'll continue my research. If you have any more ideas on how to acheive this just keep me posted plz.
