turning the previously generated large surface in smaller subsurfaces.
-each subsurface (the "curved pizza slices") itself should consist of randomly arranged triangular panels
these panels are supported by a grid of thin steel beams, which themselves rest on larger curved steel pipes (the catenary dome ribs as seen in part 1/2)
- no duplicate ridge pipes
- no duplicate nodes
the script is executed roundwise (step-by-step) using hoopsnake, to ensure system stability (heavy computation)
