researCH: aDaPtive solUtions Rhino + Grasshopper Date: Jan - Feb 2009 Advisor: Mark Cabrinha This research was the first attempt at learning and exploring the use of Grasshopper as a design tool, well before the improved data management features. Its premise however, while extremely simple to replicate today, is still relevant in our material conscience economy.

“Representation: modelling :: modelling : versioning While simulation remains a useful formal estimate of future organizational strategies, versioning of vectorbased information allows immediate results to be transformed and refined as the previous tests feed additional data through the framework of intentionality. Both the desired design objectives and methodology thereby become simultaneously accelerated and adaptive.� -SHoP Architects

To what extent can a parametric tool such as Grasshopper allow new strategies of form optimization to be explored en mass? How can the pure power of a computer be combined with a designers intuitive nature about material consumption to create a process that harmoniously produces the most viable versions of form? Below: Variations in form were determined using four law curves, whose control points were manipulated parametrically. Right: Sectioning along a curved object becomes suspect as the form grows outward. By sectioning along the normal to a vector, which is linked to a geometry in Rhinoceros, manipulating the allocation of material simply becomes a matter of altering the vector, and watching the subsequent sections respond. A straight line yields jagged edges at areas of increased curvature [1], while a more extreme curve causes the sections to intersect at the outermost region [2]. When a form is chosen for further development [3], fabrication begins with cutting individual sections on the CNC. A jig was also cut on the CNC to allow the all-thread rod to be formed to the correct curvature [opposite top]. Opposite: Final prototype model. Made from .25� plywood, assembly was a matter of sliding on individual sections to the preformed all thread, followed by aluminum spacers, to achieve the correct geometry.
