[vtkusers] vtkProbeFilter.Update()

[Mathieu Malaterre]

Hi all,
  I think I didn't understand the vtk pipeline. I thought that the
'Update' method would call the Execute method again (providing the
modified time was changed).
So here is two scripts, the first one is the one that work but not
really -memory- efficient:

//first one:
for k in range(0, 10):
    probe = vtkProbeFilter()
    probe.SetSource(reader.GetOutput())
    probe.SetInput(mesh)
    probe.Update()
    //do some change to 'mesh' with the result of probeFilter
   del probe


//second one:
probe = vtkProbeFilter()
probe.SetSource(reader.GetOutput())
for k in range(0, 10):
    probe.SetInput(mesh)
    probe.Update()
    //do some change to 'mesh' with the result of probeFilter


Does anyone knows what I lack ?
Thanks a lot.
Mathieu
