Method
Performs reaction-diffusion simulation, using an image input as a seed.
This node simulates the Gray-Scott reaction-diffusion process, which can be thought of as a kind of fluid simulation with an extra step that creates organic-like patterns which grow out from seed points. Those points are created by sampling an input image, and seeds are created at the brighter parts of the image.
