Reaction Diffusion simulation of two virtual chemicals using Blender 3.6+ geometry nodes simulation zone

Free version available here

Reaction diffusion solver based on Gray-Scott model. More info about the Gray-Scott model

Settings of reaction diffusion solver inside the "Reaction Diffusion Solver"

A - Chemical A value stored on the mesh (set to 1)
B - Chemical B value stored on the mesh (set it to some random texture/noise that effect will growth from)
K - Chemical kill rate
F - Chemical Feed rate

Different K and F values:

To find more K and F values visit online reaction diffusion simulation - Karl Sims web reaction diffusion simulation

Included Marching Squares/Triangles algorithm nodes for creating isolines and cut surface from reaction diffusion pattern

Marching Squares/Triangles documentation - https://higgsas-geo-nodes-manual.readthedocs.io/en/latest/generators.html

Included files :

reaction_diffusion_marching_squares.blend
reaction_diffusion_simple.blend
reaction_diffusion_two_patterns.blend
Reaction Diffusion Assets.zip

Adding reaction diffusion solver to asset browser:

1. Unzip Reaction Diffusion Asset Marching.zip file

1. Add Reaction_diffusion_marching_asset.blend and blender_assets.cats to your blender asset browser folder (\\Documents\Blender\Assets)

All nodes (Reaction diffusion and marching squares/triangles) included in Higgsas Geometry Nodes Toolset
