algorithmic modeling for Rhino
I´ve given it a shot yesterday to replicate the basic shape of the Molteni arc tabe by Foster + Partners, see:
For this I have written a small script generating the basic raw surfaces and then have used Kangaroo to perform a mesh relaxation. In addition I have split the longitudinal and latitudinal mesh edges in order to be able to apply different spring strengths.
You can fiddle around with the mesh settings, spring stiffness, changing the saddle point, or even adding the saddle point to the set of fixed points.
In order to take it to the next level one would have to extract the mesh vertices, interpolate a surface and remesh with a tool like for e.g. Matlab to achieve the smooth equidistant grid lines such as in Mr. Peters blog. From there onwards one could add the gravitational pull to offset the relaxed surface.
Hope you like it
