Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic be

Here is some more demo code. It s not the hottest stuff ever made, quite simple most of it - but you will find a fast vector-box, wildly rotating full-screen pictures and a nifty starwars scroller. Also a very simple (but fast and easy to expand) wol
