The project “Quaddel – Recursive Growth” investigates the possibilities of algorithmic modulation of growing an organic structure. The used growth algorithm is based on a diffusion-reaction system. Originally this type has been coded by the design collective “descriptive”(C.Bader & D.Kolb). The current code is based on the development of I.Farnsworth, who also provided this. Currently, we are working on the internal logic and application to controlled forms in order to ultimately develop an application in the spatial sense.
