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. Probing with a point is different than using the Pick filter at a point because the Pick filter returns the values for the input point closest to the selected point. Instead 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).
