Graffiti Analysis: Sculptures is a series of new physical sculptures that I am making from motion tracked graffiti data. New software (GA 3D) imports .gml files (Graffiti Markup Language) captured using Graffiti Analysis, creates 3D geometry based on the data and then exports a 3D representation of the tag as a .stl file (a common file format compatible with most 3D software packages including Blender, Maya and 3DS Max). Time is extruded in the Z dimension and pen speed is represented by the thickness of the model at any given point. I then have this data 3D printed to create a physical sculpture that serves as a data visualization of the tag. For the Street and Studio exhibition at the Kunsthalle Wein, I collaborated with an anonymous local Viennese graffiti writer and had the GA sculpture printed in ABS plastic. Graffiti motion data of his tag was captured in the streets (for the first time) at various points around Vienna.
A version of the Graffiti Analysis 2.0 application loaded with data collected in the streets of Vienna during the course of the installation can be downloaded here: Linux | Windows | OSX
GA 3D was made in Open Frameworks and developed by Chris Sugrue. The Graffiti Analysis sculpture in the Kunsthalle exhibit was printed by RedEye. The project was supported in part by the Kunsthalle Wein. Big thanks to Sydney Ogidan, Catherine Hug, Sigrid Mittersteiner and everyone at the Kunsthalle for their help. Audio in the video above is by Dimlite and was ripped from Theo’s Spring Mix 2010.
GA 3D software and source code will be available at graffitianalysis.com shortly, follow @graffanalysis for updates.
I will also be premiering the new 3.0 version of Graffiti Analysis this week at Les grandes Traversées festival in Bordeaux (more info on that soon).
