Gray-Scott Reaction Diffusion in TouchDesigner (Part 1)

Learn to simulate the awesome Gray-Scott reaction diffusion system in TouchDesigner, using GLSL shaders. We discuss the mathematical basis of the system, how to implement it in shaders, tiling, and how to color the simulation using any palette!
