I’ve been trying out the MSAFluid library by Memo Akten for Processing. Starting from the example program that comes with the library, I’m making a wind tunnel. I’ve seperated adding force to the fluid, adding particles and adding dye so that I can add each where I want to.
Processing is fun because the sketching approach means that you see the results at each step, and this often provides weird / interesting visual results. These images show my wind tunnel with a ‘fan’ emitting dye and then a set of dye emitters half way down the tunnel. The particles are distributed through the fluid to show the flow.
