[vtkusers] Filter Reusage

[Jeremy Stout]

Hello, I have a couple of general questions about vtk coding.

1. Is is possible to reuse vtk filters? What I mean by that, is it
possible to use a filter with one input, have the filter performs its
transformation, change the input on the filter, and have it perform
another transformation?

2. For vtkCutter/vtkContour, is it possible to change the contours the
filter is using by using "SetNumberOfContours(0)" followed a series of
SetValue() statements?

Thank you.
