Hi,<div><br></div><div><br></div><div>Thanks a lot for all your inputs. Thanks Utkarsh for the pointer. I tried to use it but some how when I select both my meshes and then try to open python calculator, it does not happen. The tab itself is inactive when I've selected 2 inputs.</div>
<div><br></div><div>However the ICP registration gave me the desired answers. Thanks Jerome.</div><div><br></div><div>Warm Regards :)</div><div>Lisa</div><div><br></div><div><br></div><div><br><br><div class="gmail_quote">

Hi Lisa,<br>
<br>
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 :<br>
<a href="https://github.com/jeromevelut/vtkKinship" target="_blank">https://github.com/<u></u>jeromevelut/vtkKinship</a>.<br>
<br>
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.<br>
<br>
If you prefer to use ParaView out of the box, then just follow Utkarsh's input!<br>
<br>

Take a look at this:<br>
<a href="http://paraview.org/Wiki/ParaView/Users_Guide/Python_Calculator#Comparing_Multiple_Datasets" target="_blank">http://paraview.org/Wiki/<u></u>ParaView/Users_Guide/Python_<u></u>Calculator#Comparing_Multiple_<u></u>Datasets</a><br>
<br>
It shows how to compare scalar values between two datasets. You can<br>
use this as a starting point to compare point locations too ( use<br>
inputs[...].Points instead of inputs[..].PointData in the example).<br>

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