A couple more useful settings from Reaction-Diffusion Playground: https://jasonwebb.github.io/reaction-diffusion-playground/app.html
Stable solitons.
These things space themselves out nicely so it could be used to place voronoi points.
Worms.
They look like fingerprints.
If I can get something similar to this but with the occasional branch then I could use that for the primary veins of some insect species’ wings.
Refactored so I can vary the diffusion rates as well as the feed / kill rates.
The top-right corner is looking better than the rest.
Searching a Parameter Space #
Feels a bit like I’m doing this search in an old-school way. Sure, I’ve automated exploration of the parameter space but I’m still the one looking at each and every output and deciding whether it’s going in the right direction or not.
Perhaps a more modern approach would be to train a model on the kind of output I’m looking for and use that to automate the exploring.
Maybe I can do something a little simpler and just count the number of black pixels and pink pixels. Some measure of the amount of variation.
Maybe later. (-:
The Search Continues #
I kept Diffuse A at 1.0, Diffuse B varies on the y-axis and Feed Rate on the x. We’re getting somewhere.
This one, Case 28, even has that ladder shape reaching across the gap.
Cases 13 and 14 have mostly solitons but there’s some reaching across the gap there, too.
It’s too bad in all cases these features lag way behind the diffusion front.
I watched the animations… it’s not what I expected. Need to generate some GIFs to embed here but I’ve kinda painted myself into a corner with the grid of results thing.
