David,J-S,Art,
Yes this the direction I envisaged for it, I attempted to pull out some common variables into an OceanTechnique base class, but as you can see in the code, that all went a bit pear shaped as I didn't really know how the others were going to be implemented.. The CUDA implementation is certainly something to look at but should be seen as an alternative rather than a main route as it excludes people with lesser graphics cards and, dare I say, it the ATI contingent. There's a nice video here if people are interested. http://www.youtube.com/watch?v=K1I4kts5mqc K. -----Original Message----- From: [email protected] on behalf of Jean-Sébastien Guay Sent: Wed 06/05/2009 20:07 To: OpenSceneGraph Users Subject: Re: [osg-users] osgOcean release Hi David, > I would suggest that an all GPU FFT would just be one in a selection of > possible ocean surface techniques.

I'll be looking into how feasible this is, not just for offloading surface generation to the GPU, but in general for allowing selecting the surface generation technique from a list of possible techniques with different tradeoffs. As soon as there's a non-GPL alternative integrated instead of FFTW, I can start working on that.
