Hypar Surface Approximation2019Research Grasshopper + Galapagos @DFL The 9 hyperbolic paraboloid surfaces of Le Corbusier’s and Jannis Xenaquis’ Philips Pavilion can be devided in 2 families: four-sided and 3 sided ones. The four-sided hypars are easily modelled using their straight edges ( which are also rulings in 2 directions) as inputs for sweep commands. The 3-sided hypar sections are the result of regular 4-sided hypars, which were sectioned by a ground plane, resulting in the characteristic curved plan of the pavilion. In these cases, if we sweep an edge ruling line along the curve, we will get a surface similar to the hypar, but not actually one, which can have undesirable effects for instance, in robotic hot-wire cutting. Therefore, a simple method was developed to approximate hypar surfaces, using the evolutionary solver in Grasshopper, Galapagos to:
use as input, the existing lateral ruling edges;
create a 4th random point with variable coordinates;
Generate a hypar surface and intersect it with the ground plane, creating the ground curve;
Find the average distance of this curve to the desired curve in plan;
