[vtkusers] vtk histograms

[Erik Anderson]

Hi all,
     I am trying to do some shape analysis in VTK.  I have 
an isosurface which I wish to analyze.  Right now, I am 
having no problems coloring it via vtkCurvatures to 
extract curvature information.  I would also like to get 
this same information as a histogram.  Unfortunately, I 
can't seem to find a way to get the PolyData output of the 
vtkCurvature filter into a form usable by the 
vtkImageAccumulate  method.  Is there some way to do this 
(or another way to arrive at the same results?)

Thanks,
Erik
