Needed: Reaction-diffusion model using a shader
-
last edited byHas anybody ever implemented a reaction-diffusion model in Pythonista using a shade, preferably with 2 differential equations . I would love to get/make an pythonista version of the gray-scott model, but I do not have enough to start with.

last edited by cvp@JohanvdK I had never heard of diffusion reaction. I just tried to read an article on Wikipedia, and, wow, I had not seen differential equations for almost 50 years ...👴🏻
Good luck

last edited bySure, in plain python is easy. I could use some help implementing it as a shader, like the SimpleNoise example. J.

last edited bySearch shadertoy for reaction diffusion, and see if there is one that does what you want. For the most part, I think the stuff you can find on shadertoy should work with minimal work in pythonista.

last edited byLooks interesting. I can’t test it yet as I only have an ipad with me. Thanks! J.
