Hi Claudio, how do you know the panels in the Foster design are all identical?
Panelling with identical panels is a very complicated area of geometry. There are a number of obvious solutions: - rectangular, triangular and hexagonal planar grids) - icosahedrons and other platonic solids - singly-curved surfaces with rectangular panels (this one only works for identical panel shape, not joint-angle) - special cases where the underlying surface is a direct emergent result of the panel geometry (for example penrose tilings) And then there are weird special cases. I found that many architects/engineers who face a facade-panelling problem don't even try and come up with a single panel solution. Instead, they try and minimize the number of different panels they need to build the whole shape more or less accurately. This is always a per-project problem that requires a per-project solution. Sometimes they'll even design the panel and the underlying surface at the same time, which gives you much more possibilities for solutions. -- David Rutten da...@mcneel.com Robert McNeel & Associates On Mar 31, 12:23 pm, Claudio <claudioarch...@gmail.com> wrote: > Hi David, > > Can you please be more specific, In which cases this can be possible? > I'm also iterested in diving a surface with identical panels.
