A Cardboard Column With 16 Million Facets – Michael Hansmeyer in Berlin

One of Michael Hansmeyer’s cardboard column is in an exhibit right next door to my house at Smallspace Gallery, Berlin. He is a computational architect who examines the use of algorithms and computation to generate architectural forms. This project, Subdivided Columns – A New Order is a 9-foot column that weighs nearly 2,000 pounds generated by iterating a subdivision algorithm and then utilizing a laser to delicately slice each segment of cardboard. Michael Hansmeyer uses algorithms invented by Pixar.

A full-scale, 2.7-meter high variant of the columns is fabricated as a layered model using 1mm sheet. Each sheet is individually cut using a mill or laser. Sheets are stacked and held together by poles that run through a common core.

The calculation of the cutting path for each sheet takes place in several steps. First, the six million faces of the 3D model are intersected with a plane representing the sheet. This step generates a series of individual line segments that are tested for self-intersection and subsequently combined to form polygons. Next, a polygon-in-polygon test deletes interior polygons. A series of filters then ensures that convex polygons with peninsulas maintain a mininimum isthmus width. In a final step, an interior offset is calculated with the aim of hollowing out the slice to reduce weight.

Avec. Praline teamed up with The Model Shop for the If You Could Collaborate projectan excellent set of designers and equally adept architectural model makers. The results are understandably broad, and include a new typeface, architectural models, a neon sign and most importantly one fantastic concept.
