pattern Distortion and stretching process The new design intent for the pattern was composed of stretched corners in the zones with high curvature. After the nested sphere packing process the resulting pattern was compressed instead of stretched in the corners of the facade [1]. GT developed a method to parametrically stretch the pattern so that the architect could choose how far he wanted to stretch the panels [2,3]. Stretching the pattern according to the architect’s design intent was achieved by creating a parametric rig. This enabled the architect to easily see many iterations of the pattern with different ratios of stretching. The overall construction of the rig was simple. First, a series of splines were constructed by vertically connecting wireframe intersection points and extended along the master design surface [4]. Then the intersection points could be redistributed along the spline at different ratios until the desired effect was attained [5-7].
