im trying to get planar hexagonal panel on a dome structure i also tried using kangaroo but it didnt work for me .
i think it has something to do with the way the surface is constructed and the grid is applied to it.... because its a parabolic surface (or dome) the subdivision is a radial one and that changes the way the hexagon are mapped on the surface
(hope that was clear )...
a link to the discussion i opend yesterday that has my model and GH definition
I was wondering how to solve the extrusions of these planar hexagons to turn them into solids that share their sides. I'd considered offsetting the starting surface and creating congruent panelizations in both surfaces, where I then loft each edge curve of the original surface to their corresponding one in the offset surface. However, I'm working with the kangaroo p-hex definition that Andrea recommended, and I don't know how to get this similar panelization in the new offset surface.
I know that simply extruding each phex face along its normal will create gaps, or collisions, between each hexagon box and their neighbours.
I imagine that offsetting each phex face as a plane and finding the intersections between each plane might work, but I wouldn't know what to do after finding these intersections between planes.
How did you do it, Arturo? Or would anyone else know how to do it? Any tips are welcome. I'm working with a GC>0, double curved surface, like the one Arturo is using.

thanks Andrea Graziano ! great tutorial
