Perhaps apply vtkImageGradient twice?? (maybe vtkImageGradientMagnitude would be
more appropriate)....john

Hi vtkUsers,

I would like to know if there is a class already coded that enables to
compute 2nd order (or any order) derivatives of a vtkStructuredPoints, a
vtkImageData, or anything else.
Thank you

Thomas (tdeschamps at lbl.gov)
(ps: I would like to thanks all the persons that answered me concerning
the choice of a good GUI)
