Blender 3.6+ Geometry Nodes Reaction Diffusion Solver

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

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 at online reaction diffusion simulation - Karl Sims web reaction diffusion simulation
