Yeah great, would be really nice to see how it looks with better noise. Here is the video of how it looks now.

Fluid Dynamics - Curl Noise

I had another go at using Curl Noise to approximate fluid flow. I have been following this paper somewhat Basically a grid is generated and at each point a noise value is obtained (just a scalar value). Then from this noise the fluid flow vector field is derived (just by taking the curl) and so you get turbulence over the whole grid. My noise is crappy (just a function like sin(x*y) so bear that in mind). Then a mask is added on top which is by default 0. When the mask is 0 you see no turbul…
