I cannot download the PDF - the server times out so I have a question here: what is the advantage of this technique?

More than advantages, it's just different.
It reproduces sea waves(not random heigths like perlin noise) in a specific direction(wind direction), so it's more realistics for some kind of scenes.
A don't know if you have hear about Unigine, but them have a island demo that uses FFT water and whit some postprocessing filtrers and good model it's really awesome. Here the link:

I've planed, after realease the 0.5 version of Hydrax(That must fixes 'all' bugs, has 3 geometry modules and 2 noise modules) starting a little showcase demo like this unigine demo, including hdr, light scattering, PSSM, depth of field, etc... no to play(it's too fps heavy), just eye candy demo.

Well it is an attempt to fix the thing I noticed that is quite unrealistic in Hydrax. That the waves are only going up and down. To my eye it is definitely an improvement.

You've reason reptor, it's about time Hydrax has a good noise module, I'll record some videos of current results and post them in some hours, the achieve results at the moment are really great.

This looks really good!
Huge improvement in the realism of the movement of the ocean.

@Xavyiy : Did you check Cuda SDK FFT ocean demos/source ?

Hi tuan, no, I haven't check it, I'm going to check it now. Thanks

Looks good. Its exactly what I need!!!
One thing: Would you be able to have large rolling waves? The scene i am trying to create is on a big ship out to sea with a large swell (Big waves!)
Gus
ps. Keep up the excellent work!

@al2950
The new FFT noise module apports a lot of realism to scenes like you are trying to obtain wich the Perlin noise can't apport. Big and choppy waves can be created for storm envinorenments and ocean scenes.

wow, that looks so very good, i want to go swimming
