This installation represents the basic components of computer graphics: the vertex and the edge.
Created by Oslo-based design studio Void, Irregular Polyhedron Study #1 is a physical representation of the very basic components of computer graphic, the vertex and the edge. The mesmerizing installation by Bjørn Gunnar Staal and Joakim Hoen explores the perceptual gap between the flat and the spacious, the analog and the digital, and addresses the inquiry of “When does a collection of arbitrary connected lines start to read as a volume? Does this perception change when the shape is altered?”
The project was a site-specific installation created for the window gallery Kungstensgatan 27 in Stockholm, which ran from November 2014 through February 2015. The exhibit itself consisted of a wireframe polyhedron made from black elastic bands that was strung up by fishing line and connected to nine stepper motors. As Creative Applications reveals, these steppers were controlled by five Atmel based Arduino boards and Adafruit Motor Shields, and an openFrameworks application simulating the overall motion scheme.
“The shape’s behavior became an erratic combination of several layers of noise and randomness combined with the occasional kick back from the steppers giving in to the overall tension in the shape,” Void explains. “A conscious choice was made not to avoid this behavior (it’s not a bug, it’s a feature!) and rather have it add to the uncanny nervousness and personality of the sculpture.”
The geometry was generated using Rhino, grasshopper and Kangaroo as an optimal compromise between the dimensions of the room, possible placements of motors and the directional vectors of tension towards each vertex. This model was then exported for physics simulation in openFrameworks and numbered measurements for cutting and connecting physical pieces of string.
