That sounds pretty straight forward. I've done something similar a while ago with random polygons rather than hexagons but couldn't manage to get results for anything with negative gaussian curvature even with Kangaroo.

Maybe I'll get back to that since Kangaroo 2 is out now :)

Hi Quirin M,

Thanks for you curiosity, in my case it depends on the Gaussian curvature. I used the hexagon pattern component of Weaverbird and set the T value equal to 0.5 (some kind of neutral position because it is the result of a Gaussian curvature of 0). Using the Kangaroo2 solver for solving for planarity results in the above structure. for synclastic areas the well known honeycomb hexagons appear while for anticlastic areas "star" shaped hexagons appear. The background of this phenomena can be found in the Dupin Indicatrix which describes characteristics of a point on a given surface. (Lisle, R.J., (2003), Dupin’s indicatrix: a tool for quantifying periclinal folds on maps, Geol. Mag. 140 (6), Cambirdige University Press, UK, pp. 721-726).

Nice. How did you solve the problem of planar panelization on a concave surface?
