[vtkusers] How to extract Scalar and Point Data from ProbeFilter?

[FUJII Kenji]

Hi there,

I want to extract Point and Scalar Data from ProbeFilter that was Probing or 
Cutting from Polydata.

To extract them, I was trying to call some function (GetOutput, 
GetPointData, GetScalars etc...)
But It doesn't work well. What I tried in Python is as follows.

// ----------------------------
probe = vtk.vtkProbeFilter()  # or  cutter = vtk.ctkCutter()
...
data = vtk.vtkDoubleArray()
data.SetNumberOfComponents(1)
data.SetNumberOfTuples(20*20)
data = probe.GetOutput().GetPointData().GetScalars()
print data
// ----------------------------

The result of  "print data" was (None).
I think vtkProbeFilter and vtkCutter may not have Point and Scalar data.

Please reply if someone knows how to extract their data.

Regards,
