double dome structure

Hello,

I am doing something like a double dome structure for my final thesis and I am trying to do the structure as a CNC cut timber structure ready to be put together on site.

Luckily I found some supporting files on the forum how to triangulate or voronoi-ate the basic surface, but some problems ocured on the way.

When doing the triangulation, some triangles look like they should, and some (on the corners) looke more like a line then a triangle, so how could this be corected to get them more like equilateral triangles.

The second ghx file is a script to voronoi the structure, similar problem: all the cells look too longitudinal, not very voroni-like. and another qustion: how to do surfaces out of the lines and then list them like in the "surface unfold" script

I think the problem lies in the basic surface, because I modeled it with loft along some curves. I did not come up with a better idea how to model.

a basic idea how the interior would look like( The Voronoi Pavilion, in Lima, Peru, designed by Natalija Boljsakov and Brian Miller)

If you could please help me, to get a more pleasant/logic structure of the dome.

Thank you very much in advance

Jernej,

I would suggest looking at Kangaroo for your dome structure. You should be able to create a planar mesh that follows the edge of your dome then apply an inverted gravity to the mesh points to create the dome shape, you'll need to also apply the surface of the dome as a ceiling to the inflation to match the shape of your original form, this should at least give you more regular divisions of the forms rather than mapping to the surface. It also will give you something that is more structurally rationalized like a series of catenary curves.

Good luck

Thank you for your reply, but I did not understand any of the words you wrote. I have enough problems with grasshopper, so I dont even dare looking at Kangaroo for solving my problems.

Thanks anyway, jernej
