Invisible Cities: Sculpting Poetry into Imaginary Cities

Celebrating Italo Calvino’s “Invisible Cities”, our project sculpts the words of “City and the Sky” into a 3D printed generative fragment of Upper East Manhattan that reimagines 69 blocks of the city.

To generate the sculpture we assigned one of six possible classes to each word of the text: verbs, nouns, pronouns, adjectives, adverbs and other words; and assigned a unique building typology to each class, to map the position of the word in the text to a physical position within Manhattan’s grid. For example, every time a verb appears in the text, it would be represented by a skyscraper mapped to its relative position within Manhattan’s grid. The resulting model was edited in Meshlab and Netfabb to repair the meshes and to prepare it for printing. The final model was printed on a Z Corporation Z Printer 650.

The building typologies are distributed following the occurrence of the words in Calvino’s text.Poster2In the following slide, you can see the ‘government building type’, a building typology that represents the occurrence of one of the five cities in Calvino’s text-Eudoxia, Beersheba, Thekla, Perinthia, and Andria.CitiesEach block contains sixteen lots, each of one containing one ‘building structure’.   Blocks
