FFT 2D with openCL ideas about how to do it ?

Hi everyone !

I am looking for an algorithm to make a 2D fft in open cl.
The one i’ve found, only do it with a 64x64 grid which is too weak for our application…
If you have any ideas about it, or, where i could find a function to make it don’t hesitate to tell me…

Thanks a lot !

I’ve forgot to add that i’m using microsoft visual studio on window seven.

You definitely want to try this: OpenCL FFT

The reference computation involves Apple specific code, you can strip it and keep the OpenCL part which works (I ran it on Windows 7 for benchmarking purposes)

Best regards
