I have two 3D vector fields in a 3D array. One has dense information, the other goes on either side of the first and has a different cell thickness in the z direction. I would like to combine the vector fields and then use streamlining. Can Paraview handle this sort of thing?

I’m assuming the streamlining won’t work unless I first combine everything into one vectorfield object. Is that correct?

You can use the `Resample With Dataset` filter to sample the fields of one data object onto another data object.
