<TITLE>Too many gradient filters</TITLE>
</HEAD>
<BODY>
<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>At the request to look at the Dashboard, I noticed that a new gradient filter, vtkDataSetGradient, has just been added. This makes the <I>third</I> filter to perform gradients on data sets (the other two being vtkGradientFilter and vtkCellDerivitives), and that does not include the filter designed to compute derivatives on image data.<BR>
<BR>
Rather than add yet another filter to perform basically the same operation, could we have some effort at consolidating these filters?<BR>
