[Paraview] calculate distance between pair of meshes

[Jerome Velut]

Hi Lisa,

If you are OK to compile your own plugin in ParaView, you can try to 
include the ICP registration to the Filters menu. I did it and 
open-sourced it :
https://github.com/jeromevelut/vtkKinship.

Regarding the distance between points, a VTKJournal publication presents 
an implementaion of the Hausdorff distance between meshes and its 
ParaView plugin. Note that it is not a point-pair distance, as the input 
meshes are not expected to have the same topology.

If you prefer to use ParaView out of the box, then just follow Utkarsh's 
input!

HTH,
Jerome
