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

Lisa,
Take a look at this:
http://paraview.org/Wiki/ParaView/Users_Guide/Python_Calculator#Comparing_Multiple_Datasets
It shows how to compare scalar values between two datasets. You can
use this as a starting point to compare point locations too ( use
inputs[...].Points instead of inputs[..].PointData in the example).

Hi List Users,
I'm a fairly new addition to the paraview user community. I've experimented
with a few tools in paraview and I'm impressed. I have two meshes or rather
one mesh and a transformed version of the same. Is there any tool/utility in
paraview that would help me find the transformation between the two? By
transformation I mean translation along the X, Y and Z axis, rotation along
the 3 axis and the scaling factor? Or at least is there any method to
calculate the distances between pairs of corresponding points on the 2
meshes?
Thanks a lot
Lisa :)
