The #WCCChallenge this week was "space-filling algorithms", and the group had a ton of really good contributions.
I chose to create a diffusion limited aggregation system. It was something that I explored in my early code art days over 20 years ago, so it felt good to be able to whip up something much better in a fraction of the time. There are several variations, and it's fun to watch it slowly build up.
I made a fork of the DLA sketch to use motion that is more similar to that of my original design. The particles still have a slight bias to move in the direction opposite of the start side, but otherwise they can move in any direction and drift more. It leads to more sparse and wavy formations like in the POV-Ray set. The images show examples with the different particle lengths. I think I like the red/blue color combo a bit better. https://openprocessing.org/sketch/2177509
And in case anyone was curious, here are some renders from the #Povray DLA simulations I did back in 2002, based on some stuff I read in the math library at the U of MN. This version produced a beautiful lacy structure. I wrote the state of each grid cell to a huge array in a text file, so then I could render from it multiple times to experiment. The initial simulation/parse took about 30-60 minutes. I experimented with making more artistic renders with them, but didn't go very far with that.
