The "Probe Location" and the "Resample With Dataset" filters actually use the 
same code underneath the covers. The only difference is how the geometry source 
is inputted (internally generated points for "Probe Location" and another 
dataset for "Resample With Dataset"). Also "Probe Location" is marked to by 
default show the results in a table view. However, you can show the results of 
"Probe Location" in a 3D view as well. Just select the 3D view and turn on its 
visibility.

Anyway, the point of all that is that it should be unnecessary for you to run 
the "Resample With Dataset" filter. You should get the same data from the 
output of the "Probe Locations" filter.

If all the field data in the output from "Probe Locations" are zero, then there 
is some reason why the filter could not find field data at the selected points. 
Once common problem is that the points are not actually located within the 
volume of your data. If your input data is actually a surface, then this is 
likely as it is hard to place points exactly on the surface. Another cause for 
problems that recently came up on the mailing list is issues with using an 
unstructured grid dataset that has voxel-type cells in it. The thread is 
captured here: http://markmail.org/message/t5vbs7opn43wtkdw.

Subject: [EXTERNAL] [Paraview] Question about probe point data

Hello,
I am trying to probe point based data with Paraview.
What I did is:
1) Create probe points with "ProbeLocations"
2) Then use "Resample With Dataset", choose input as the data that I have 
already had and source as "ProbeLocations" that I created in the previous step.

The trouble that i have is:  All field data including coordinates are all zero.

Could someone help me out?

Thank you very much!

Orman
