FFT3dGPU is a GPU version of Fizick's FFT3DFilter. The algorithm (Fast Fourier Transform, denoising) is the same for the most part. Currently the following is not implemented: support for noise pattern.
Q: I get this errormessage: "Only pixelshader 2.0 or greater supported"
A: It is because you need a graphics card that has hardware support for Directx 9.
The following cards will
not work:
