Fibonacci Dome

This is the continuation of my previous study on the Fibonacci lattice on a spherical surface, creating a Fibonacci Dome structure. The panelization of curved forms with flat surfaces has been a favorite topic in architectural geometry. The trigonometric layout of the Fibonacci sequence generates a spherical formation, while the Faceted Dome component handles planarity. Here, I further enhanced the previous code into a pavilion design. The essential part of the code is about the placement of points on the half sphere by checking the Z coordinate of the calculated points. Finally, I extruded the faces for the thickness of the panels. There are many variation possibilities in this dome design.

This Grasshopper definition generates the variations of Fibonacci Dome structures with several input parameters. The user-controlled inputs are the n variable, which controls the number of Fibonacci points, the radius/height ratio of the dome, and the thickness of the dome pieces. The resulting objects are closed polysurfaces. Therefore, it creates the essential data for the production of a potential structure on any scale. I made the definition with the help of the native Grasshopper components in Rhinoceros 7. So, you don’t need to install any add-ons to be able to use it.
