For very large

However, since the FFT technique is tileable it would be possible to only

Hi Umit,
Now I have achieved to GLSL 1.2 and OpenGL 2.1 but it still not enough.
I am trying to update to 3.0.
Whether or not your driver supports OpenGL 3.0 won't make any
difference, OSG does not use OpenGL 3.0 at all (you need to explicitly
create an OpenGL 3.0 context in order to use

Bear in mind that so long as your wave numbers are integer subdivisions of
the tile size, the result from an FFT approach is the same as the result
from a sum of sinusoids approach, just higher performance.

FFTW is GPL. Are you concerned about this?
