How to implement a simple 2D convolution (FFT + point_wise_product + iFFT)

[jasmineforever]

Hello:
I'm new to vkfft, it's awesome! I still learning how to use it. I read the sample codes and didn't see a similar pattern like “FFT + point_wise_product + iFFT” convolution. Does vkfft support such a pattern?

Hello,

Sorry for the slow reply, for convolutions you can see samples 50-52 - they all do this pattern. You can also check section 5.6 of the documentation. Essentially you need to create the kernel with separate kernel application with the following parameter
kernel_configuration.kernelConvolution = 1;
and then create main application with
convolution_configuration.performConvolution = 1;
and pass kernel in convolution_configuration.kernel.

Hope this works for you and if not I will happily try to answer your questions.

Best regards,
