Subdivided Columns (Computational Architecture) by Michael Hansmeyer


Computational architect Michael Hansmeyer has created a series of stunning columns using complex computer algorithms and then constructing each column by layering 1mm thick [cardboard], each intricately cut and then fixed on top of another. 

The complexity of each slice must have taken a lot of thought and the outcomes are just truly mesmerising! I haven't seen anything like it! 

Since I don't understand all the complex computer stuff to explain it in my own words, this is some info from his official site:

"This project involves the conception and design of a new column order based on subdivision processes. It explores how subdivision can define and embellish this column order with an elaborate system of ornament."

"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."
