Reaction-diffusion

Reaction-diffusion is a model used to simulate the chemical reaction between two substances 'A' and 'B'. 'A' turns into 'B' when it is in contact with it. Additionally, a little 'A' is continuously injected, and a fraction of 'B' slowly destroys itself.

This is a GPU implementation of the Gray Scott model. It exhibits natural-looking patterns, reminiscent of corals or some animal coats. Use the left mouse button to interact with the simulation.
