Surface Reaction Diffusion
The Surface Reaction Diffusion node runs a simulation of two virtual chemicals reacting and diffusing on the 3D surface using the Gray-Scott model.
For more information about surfaces see surface workflow.

Procedure
To run the Gray-Scott simulation on a Surface:
- On the left toolbar choose Mesh Nodes > Surface Reaction Diffusion. >
- Connect the Surface Reaction Diffusion node to a Surface value and an Image value.
Inputs
Surface
The surface value.
Image A
A surface image that represents the concentrations of chemical A before the simulation is run.
Image B
A surface image that represents the concentrations of chemical B before the simulation is run.
Outputs
Surface
The surface value.
Image A
A surface image that represents the concentrations of chemical A after the simulation is run.
Image B
A surface image that represents the concentrations of chemical B after the simulation is run.
Attributes Panel
