# The vtkProbeFilter takes two inputs. One is a dataset to use as the probe

# geometry (SetInputConnection); the other is the data to probe
|
|
# (SetSourceConnection). The output dataset structure (geometry and
|
|
# topology) of the probe is the same as the structure of the input. The
|
|
# probing process generates new data values resampled from the source.
