I hope people have the DivX codec. I tried with mpg1 but it wasn't as
effective in compressing these images.

The experiment can be broken down to:
1) Generating waves
2) Having wind in a box, or maybe not...


GENERATING WAVES:

This is Christoph Hormann's code for realistic ocean waves. The catch is, I
made it into a map that tiles seamlessly. The water you see in this
animation could fill a larger area simply by repeating the map. This is
useful to save memory and rendering time. In this case the map is small
(128*128 pixels) but that's because I didn't need more to fill the box.

So it's not necessary anymore to use a slow isosurface, or a height_field
with an insane resolution, to fill a lake or an ocean. Though, the ocean is
still going to need a whole lot of HF objects.

There will be some visible repeats (although it's seamless it does degrade
the quality) but with good settings, I don't think it's too bad.

The waves also loop over time, as you may have noticed this animation loops
nicely. The purpose is that the map can be pre-rendered and used in
animations with any length. This saves a lot of parsing-time too, generating
the maps.


WIND IN A BOX:

I'm not successful in simulating wind in a box. I also didn't implement any
interaction with the walls but I thought, it might not be necessary in such
a simple case. Turns out, it is necessary. As Christoph said, his code is
not suited for small amounts of water. I just haven't found a good
alternative.
