Another series of sketches exploring organic curves.  Particles follow wandering paths, stopping when they cross another path. The shape of the path, the number of particles, the initial starting positions, the way the particles die,… all have a major impact on the final image.

The ultimate example of this drawing mechanism is Jared Tarbell’s masterpiece ‘substrate‘. Some of the fine pieces by Dave Bollinger also seem to use something like it.

Click on the image to go to the corresponding construct. A click of the mouse resets the piece. On some platforms the lines are not properly anti-aliased. I haven’t figured out why but it sure messes up the images.

I have to admit, I’m hopelessly fumble-fingered in vector drawing. I never get the curves right, somehow they’re not smooth, not natural looking.

The funny thing is that a 1000 particles chasing each other from random starting positions seem to manage this quite nicely. Initial jagged chaos swiftly evolves into flowing curves, continuously trying to simplify themselves. Guess I’m not a sufficiently complex, self-interacting system

Anyway I’m rather pleased with this construct. Pointless overkill makes me happy. The construct and its code can be found here. There’s no interaction beyond resetting with a click of the mouse.

Update: Lucas Tamarit pointed out, somewhat uh… pointedly, that this piece is very similar to ’sandtraveller’ by Jared Tarbell. Check this and the rest of his work out here. I’ve got to agree there’s definitely a resemblance. However, I’ve checked out the code and the mechanics behind ‘cyclic’ are really different from ’sandtraveller’, as is the rendering technique. I invite everybody else to make the comparison.

Up to now, I’ve always treated particles as their physical equivalents: pointlike objects undergoing forces. As a physicist, this way of thinking comes natural, however it is fairly limiting. There’s a lot of work out there dealing with particles as agents, capable of steering towards goals, avoiding obstacles and flocking together in interesting ways.

Towards is my first step in exploring the possibilities of agent-generated graphics. It has an old-fashioned feel about it. (And yes, I got stuck on the black-white-red palette again…)

To get a feel of how this kind of explorative programming goes, I’ve uploaded seven versions showing the chronological (pro/re)gression of the code. All pieces need some time to reveal their true dynamics. Click on the applet to restart the construct.

For some unfathomable reason I’ve been spending my nights doing the dishes and, amazingly enough, sleeping. I’ve much have caught something. Anyway, two samples of work in progress, both based on the voronoi code.

Don’t ask about 3. Three is not a nice piece, it escaped. It lurks in the space between the walls, growling… Occasionally, it comes out and eats computers.
