I’ve been experimenting with extruded shapes, with the end goal of fabricating some interesting ones using a 3D printer at the University I teach at, University for the Creative Arts, Farnham (UK).
So far, it has been a long learning process – first, making extrusions of my hands using Fluxus and a custom-written OpenCV-based image-outline-tracer in C++ (using some OpenFrameworks); then, using Dave’s extrusion functions in fluxus mixed with my live-drawing sketches, coupled with the OBJ-file export, and finally imported into Blender (for some nice ray-tracing).
The trouble is, I can create 3D shapes but hey have no “solidity,” which means their outlines have no thickness. Apparently you can’t 3D print objects and just hope that they are thick enough, or tweak it on the machine, as I’d hoped. No, as with all computers and electronic devices, they only do EXACTLY what you tell them to do, and nothing more or less.
The image here is a reject from Fluxus/Blender, where I created an inner shape by duplicating the original shape and growing it outward along its normals (used for lighting, normals are perpendicular to the surface of the object, meaning they point exactly outwards and are useful for expanding shapes). The problem is that my shape is so complex, I can’t get away with simply growing it. I’m going to need to do some horrible maths, I can feel it…
Still, I really like this image. I’m a big fan of Salvador Dali (don’t laugh) and the infinite blue background and contrasting, surreally-melted hand shape in front lends this image a particularly Dali-esque quality, I think.

I’m proud to announce that the gang at SketchPatch.net were kind enough to make me the featured artist this month!

For those of you who haven’t seen it, SketchPatch is a playground for Processing sketches, where you can create, edit, share, and copy others’ sketches. All sketches on the site are Creative Commons 3.0 attribution licensed, which means you can copy the code and use it as long as you give credit to the original author(s).

Resonance Livecoding with Gabor and PixelPusher, photo by Dave Griffiths
Resonance Ghent invited a group of livecoders, audio and visual to perform livecoding all day in the delightful little gallery Espace Ladda, next to the Vooruit cutlural center, in the center of town. As a piece of what can almost be described as “productive performance art” we sat in a tight circle of laptops enmeshed with projectors and surrounded by projection screens, grinding out audio and visuals from live software coding. Interested people wandered around us, and occasionally asked what we were doing, sparking off some pleasant conversations about all things art, code, visual, and audio.

This is my suped-up version of the old flight404 and toxi Processing sketch – it uses Perlin noise to create a moving field of very organic-looking daggers. toxi used it for hairs, and now I made an intricate version that uses 3D daggers drawn using OpenGL.
