[laurent_delrieu]

You put a multiplication instead of addtion

Good exercice but super long.

Fast Gray-Scott reaction-diffusion C# component using Alea for GPU computation

I wrote a component that computes reaction-diffusion like this, Reaction-Diffusion Tutorial, on a mesh. It builds on Vicente Soler and Laurent Delrieu’s work here reaction diffusion on triangular mesh - Grasshopper . Thanks guys! I extended the inputs to take either a single value, or one for each mesh vertex, so f, k etc. can vary over the mesh just as the dir input for flow direction already does. I used Alea 3.0.4, http://www.aleagpu.com/release/3_0_4/doc/, to do the computation on the …
