Checkout Gentle Introduction to Realtime Fluid Simulation for Programmers and Technical Artists for building intuition over the code

Meh...it's just fluids, Pilou, hehehe... I think, I'm okay with that. Thanks, though!

It was more for tourists like me! There are a lot of links at the end of the "gentle fluid introduction" !
That gives a little idea of what are all this even i never will make this fabulous simulation!

Use it like in your Vervette yes!
Long life to the coders!

Hahaha! I toast to that, too!
I yet have to see someone trying to do proper real time volume fluids, which is something I wanted to try forever. I have such a simple idea that could totally work. But there's not really a 2d use for it, except for looking cool!
Still... one day I'll give that a try.
