Fluid dynamics

Here’s another one for the mind-blown category and it is part of a library of GPU based simulations.

Simulation is based on the “stable fluids” method of Stam [1,2]. For simplicity the application does not perform diffusion, but the used Advection algorithm causes it to diffuse anyway (due to bilinear interpolation of the 4 closest texels).

Well that clears that up then! It’s fairly safe to say that I don’t really understand the maths going on here, but if you properly want to get your geek on, then I’d check out the other examples too.

[UPDATE] It seems that fluid dynamics are all the rage at the moment. Check out this canvas based interactive version by @ohunt via zacharyjohnson.
