  Generative Art while learning Rust (by damoonrashidi)

Thanks! Some splits are randomly generated by traversing the line and each point has a small chance (5% or so) to create a split and change color. I've tried other techniques as well where lines change color by which region of the the canvas they are in etc.

I even wrote a small UI using Rust and egui to render the drawings in real-time just to play around with that specific part. It looks like this https://imgur.com/a/Zfp1ls3 and is open source https://github.com/damoonrashidi/generative-art/tree/develop...

I implemented a something similar[0] a while back in rototiller[1], there's a short low-res youtube clip here[2].

It was a fun little hack, I didn't realize this is a thing. I was just messing around with an idea of pushing particles through a cube of tri-linearly interpolated direction vectors, without simulating any actual physics like mass/friction/fluids or anything like that.

Something which surprised me was during development I just populated the cube of vectors with randomized vectors, fully expecting I'd have to do something more intentional and clever before it was interesting to watch. But the emergent structure of the flow paths even with the pseudo-random vectors was surprisingly interesting and I just left it at that, with the addition of a second randomized field the direction vectors would be interpolated between in a ping-pong manner. When one field is dominant, it re-randomized the other, resulting in a continuously-looking evolving field...
