Hi Brad, I've tried to document the FFTSimulation as well as possible if you look at the source, at least in the trunk you should see an explanation of units etc and the paper it was based on.
http://code.google.com/p/osgocean/source/browse/trunk/src/osgOcean/FFTSimulation.cpp Here is the most up to date version of the paper, well worth a read if you're interested in understanding it fully. http://evasion.imag.fr/Membres/Fabrice.Neyret/NaturalScenes/fluids/water/waves/fluids-nuages/waves/Jonathan/articlesCG/simulating-ocean-water-01.pdf I should point out that a lot of tweaks were made to make it look aesthetically pleasing, it's not an ocean simulation more of a statistical approximation. Any further questions do get let me know. Regards, Kim.
