Hi There! I went in detail through the vtkKWEImageFDKFilter.cxx and it seems to me that it is still very much under development. Am I correct in this assumption?
Couple of things: The input is weighted, then FFT is applied, then everything in Fourier space (the necessary filtering fro a correct reconstruction) is commented out, then the data is transferred back to the spatial domain. Then the projection coordinates are determined, but before the projection image data is gathered, both variables are set to zero!!! I am not an expert in VTK. Please let me know if I am under a complete wrong impression here. sincerely, Sebastian
