[vtkusers] Display special curvatures of a polydata

[B. C.]

Please, i need your help to finish this!!!
Can someone tell me what to do to compute maximum curvatures at each point of my
polydata and display only those which are > some_value (0.5 for example).

You will need to do some reading on vtkDataArrays (get point data, get its 
scalars called probably something like Curvature, get its range) and 
vtkThresholdFilter.
