Probe Location (ProbePoint)

Sample data attributes at the points in a point cloud.

The Probe filter samples the data set attributes of the current data set at the points in a point cloud. The Probe filter uses interpolation to determine the values at the selected point, whether or not it lies at an input point. The Probe filter operates on any type of data and produces polygonal output (a point cloud).

Property Description Default(s) Restrictions
Input This property specifies the dataset from which to obtain probe values.  

Accepts input of following types:

  • vtkDataSet
  • vtkCompositeDataSet

The dataset must contain a field array ()
Probe Type This property specifies the dataset whose geometry will be used in determining positions to probe.  

The value can be one of the following:

  • FixedRadiusPointSource (extended_sources)
PassFieldArrays Set whether to pass the field-data arrays from the Input i.e. the input providing the geometry to the output. On by default. 1

Accepts boolean values (0 or 1).
ComputeTolerance Set whether to compute the tolerance or to use a user provided value. On by default. 1

Accepts boolean values (0 or 1).
Tolerance Set the tolerance to use for vtkDataSet:FindCell 2.2204460492503131e-16
