Hello happy,

it is very simple to do it. Just follow the script from there

How do you do that?

Daniel, I would love to see how you put together this definition! I have been looking into reaction-diffusion in grasshopper and the Belousov–Zhabotinsky reaction is my favorite. I have put it together in Processing, but I'm less familiar with Grasshopper.

Any chance you could share?

Thanks Pieter,

si! Maybe later add it an option to generate gif animations.

Both images are 1000x1000 px, the one below took 28 min for 1000 iterations in my old laptop, using parallelization for the x-dir loop.

Very nice Dani! Done using your HeatMap component, right?
What's the U count on these? ;)

Thanks Laurent,

it's not my intention but maybe someday. I have done this to see if there was any enough interlaced parametric space to take it to 3D using isosurface. The left side up is close, now I will try with R-D. What I want to do could be done by putting two-dimensional slices (of continuous interactions) in the Z axis, but it's not what I'm looking for. I want to have the reaction in 3d and play with the parameters to have a solid base and generate the form not in up direction, but use the appropriate parametric space that gives me a sculptural form in the up direction. Well, maybe I do not explain well, but it's simply looking for if there is any producible/fabricable sculpture within this kind of algorithms, and capture it. What will become of the other cellular automata? :)

Very nice Daniel.

Do you plan to apply it on mesh or to generate bump maps ?

a: 0.5~1.5, b: 0.5~1.5, c: 1.0; 1000 iterations.
