GML is a new open source piece of software that was developed by Jamie Wilkinson, Evan Roth, Theodore Watson and Chris Sugrue. The software which is available for Mac, Windows, Linux, and the iPad imports a .gml file which is created with “Graffiti Analysis”, and then converts it to 3D geometry based on the data. The file is then exported as a .stl file (a common file format compatible with most 3D software packages including Blender, Maya and 3DS Max) which can be printed using a rapid prototyping machine. The software extrudes time in the Z space and pen speed is represented by the thickness of the model at any given point.
Originally created for the Street and Studio exhibition at the Kunsthalle Wein, Evan Roth collaborated with an anonymous Viennese graffiti artist and had the sculpture printed in ABS plastic. Graffiti motion data of these tags were captured on the streets at various points around Vienna. This is a great example of how outsider art manages to take emerging technology like motion tracking, and rapid prototyping and elevate the experience.
A version of Graffiti Analysis 2.0 is available here for Linux, Windows, and OSX . It comes with data files collected from Vienna graffiti artists. The GA 3D software and source code will be available at graffitianalysis.com shortly, and of course there is already an iPhone slash iPad app called DustTag that you can download from the app store.
