Fabric glitch patterns by Philip Stearns

Philip Stearns prints cloth based on data. Particularly on the glitches in data. Aesthetics derived from the material of digital processes…. gotta love it. Even as a blanket.

Jonty Hurwitz; keep your eye on the toad

Liking this alot. suspect 3D printing but no time to confirm. Jonty Hurwitz. Check it out.

Tada! An NPR chip!

We used inexact adders to process images and found that relative errors up to 0.54 percent were almost indiscernible, and relative errors as high as 7.5 percent still produced discernible images.

One of the advantages of NPR techniques is that it is efficient. Instead of following the arms-race of ever-increasing numbers ray-tracing (times x bounces) it works with approximations. It also swallows errors within the look determined by the artist. So when I read about this very efficient but imperfect computer chip developed at Rice University (link above to the gizmag review), I couldn’t help but exclaim: “Wow! An NPR chip!” For the first time, I find myself longing not just for NPR software, but an NPR computer to boot.

Andrew Glennerster; the model in our brain is broken

If you try to pick coordinates in some perceptual space for each of the objects in the experiment then you get tangled up in just the same way that you do with the Penrose staircase: you cannot say whether one object is in front of or behind another one. The solution is to give up trying to assign coordinates to each of the objects.

Interesting interview with Andrew Glennerster about his work on the way we perceive the world as we move about.

Impressionist video and Ipad workflow

ArtDecade uses an impressionistic brushstroke effect on this video to great effect, apparently using the procreate iPad app. If I understood correctly, they also used this for the storyboarding workflow.

Csotonyi Massospondylus in 3D… like?

Der Spiegel reports on the Massopondylus nesting site with the above illustration by Julius Csotonyi (click to embiggen). Cool that they include an artist credit, and cool to see a master delve into 3D – if he is indeed. The image sure looks like it, but I have no insider knowledge. I’m judging by the cover, so to speak. If anyone knows more about his technique, let us know in the comments!

On his site, the image is described as a “digital painting / photographic composite“. I’ll go out on a limb and -aside from some painted touch-ups (the egg membranes and such) – call this a 3D illustration with photographic elements used as textures, background elements – the solidity of the volumes, consistency of the details and the lighting all encourage me in making this assumption. Assuming this is the case (despite my father’s warning that to assume makes an ass out of you and me), it allows us an intriguing comparison of toolsets in the hand of a talented artist – as we did with Angie Rodrigues.

On to the analysis…

Artifact Aesthetics

I haven’t written much about NPR and the aesthetics of artifacts for a while now, but developments here at brainpets GbR are about to change all that… so prepare to see more about non-photorealistic graphics again. In case you’re particularly impatient and have a mac, head over to YouGlitch and corrupt your videos. It’s all the rage. 🙂

video + brush masks = art

Sergio Albiac takes live action videos, meta-tags them with emotions, stacks them behind a portrait and melds them together with painted brushstroke masks. The result is a wonderfully impressionist-like portrait that feels eerily fitting to our times…

Creative Applications has a great write-up, check it out.

Poetry, repetition and handwriting…

Today’s post is only indirectly relevant to non-photorealism… but this piece by Elliot Burns is a poignant illustration of how the imperfections of manual repetitions can take on their own meaning. The above image represents the first 5 lines of Rupert Brooke’s poem The Soldier written over itself 350 times, once for each British soldier killed in Afghanistan (as of 28/01/2011) – the original literal meaning is buried beneath an appealing visual texture. One is a catastrophe, one thousand is a statistic…

I’m not sure what I think about using such a patriotic, empire-adorning poem, but it certainly doesn’t reduce the work’s power.

npr saves lives

Very interesting paper on the efficiency of analyzing hemodynamics (blood flow). 2D schematic layouts and appropriate color palettes improve diagnostic performance over 3D models and rainbow color maps.
