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
