Mitosis in the Gray-Scott model: writing shader-based chemical simulations
Use the parallel processing power of your GPU to simulate a simple chemical system that exhibits emergent behaviors
In order to run the simulation, we will need to store the current state of the grid (the concentration of each chemical species for each cell) at a location we are able to read during a later iteration. Experiment with different values for the speed constants k2 and k3(in the “Common” tab) and see how adding some catalyst (green species) with your mouse changes the patterns. You may have heard of Conway’s game of life in which a grid is repeatedly updated according to simple local rules in a binary way (the cells are either ON or OFF).
