Hi Sergey,
found BSD fft library, not sure how it might fit or again compatible with osg
(but seems BSD is ok to use in any projects )
http://sourceforge.net/project/showfiles.php?group_id=81507&package_id=83419
Yes, that's one of the tested libraries in the FFTW benchmark:
http://www.fftw.org/speed/CoreDuo-3.0GHz-icc/
http://www.fftw.org/benchfft/ffts.html
It's near the bottom of the list in terms of speed though (if we can
believe FFTW's own benchmarks to be unbiased of course). If we need a
dynamic unbounded ocean surface in the near future, then I think speed
of the FFT computation is an important requirement.
