Dear all:<br>
<br>
On <a
href="http://www.vtk.org/Wiki/VTK/Image_Interpolators#Gradients">the
wiki page on image interpolators</a>, I read the following:<br>
<br>
> It would be possible to add methods to the interpolator classes
so that they could return the gradient of the image at any (X,Y,Z)
point.<br>
<br>
I was wondering: has there been any progress on this side? It would
quite useful. Any thought on the implementation? Thanks!<br>
<br>
