Galapagos Annual Radiation Form Finding

2011-01-28T18:40:51.925Z

Using the latest release of diva-for-grasshopper component with the diva-for-rhino environmental analysis tool available at www.diva-for-rhino.com. Parametric form is a closed triangular panelized shape with 13 vertices constrained in movement along vectors determined by the corners and centroids of a cube. The genetic algorithm component galapagos- part of the grasshopper program by David Rutten- was used. The "genes" were the location of the 13 vertices and the rotation of the form. The "fitness" function is described by the maximal surface irradiation per unit volume. This was calculated using the GenCumumlativeSky program which is part of Radiance and accessible through DIVA. A Boston weather file was used.

Rothko Chapel rhino model with Grasshopper deflection baffle. Height, size, and concavity of deflections baffle are genomes, average daylight factor closest to 3% in the space is fitness. Low ambient bounce of 1 used for this demo.
