per request here's how I created the artwork in theoretically possible to follow, slightly unordered steps: STEP 23) use the random seed "GenArt-BanNER" which you can tell is truly random and not at all cherry picked to look the nicest. Compare for instance this one which has seed "GENART-EXPLANANANANA" ⬎

so first you gotta build a Rayhatcher, you can read about it here: https://www.fxhash.xyz/article/rayhatching-evolution it's very easy the Rayhatcher is basically a flow field and everybody knows how to do flow fields right? otherwise Tyler Hobbs explains flow fields here: https://www.tylerxhobbs.com/words/flow-fields and I used the algorithm from the paper here: https://web.cs.ucdavis.edu/~ma/SIGGRAPH02/course23/notes/papers/Jobard.pdf Then we gonna raytrace, the result of which gets you a light(x,y) function, and also a normal(x,y) function which represents surface orientation. Bbbback to the flow field, we modulate the line distance according to light(x,y) and the flow field direction is based on the normals (cross product with arbitary vector, project to 2D, normalize) and that's it really

slight correction to the first post, if were paying attention you may have noticed the image supposedly having a different seed looks exactly like the banner picture, which is because I uploaded the wrong one, this the one with `GENART-EXPLANANANANA` as seed

I think my former students would need a whole semester to study this one thread… and only very few would be able to partially understand it in the end 😅
