<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">the UNSTRUCTURED_GRID (vtk-file 1) has around 10^8 POINTS, while the POYDATA (vtk-file 2) has around 10^6 POINTS, i.e., the POINTS in vtk-file 2 are a subset of the POINTS in vtk-file 1. Additionally, the POINTS in vtk-file
2 have some rounding error so that the location of "corresponding points" doesn't matches exactly and a nearest neighbor seems necessary.</p>

<p style="margin-top:0; margin-bottom:0"><span style="font-size:10pt">I've got an UNSTRUCTURED_GRID (vtk-file 1</span><span style="font-size:10pt">) with POINT_DATA and want to extract the POINT_DATA at specific POINTS</span><span style="font-size:10pt">. However,
the POINTS are defined </span><span style="font-size:10pt">in POLYDATA (vtk-file 2) and are slightly off by some rounding error. Thus, I presume the process should look similar to:</span></p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">1) Find the nearest neighbors of all POINTS defined in vtk-file 2 in vtk-file 1</p>
<p style="margin-top:0; margin-bottom:0">2) Transfer/Store the POINT_DATA of the nearest neighbors in vtk-file 1</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">I've been searching the forum for hours, however, couldn't find a solution to that problem. I was wondering if there's a simple solution of doing this in Paraview? I'd really appreciate your help on this issue, thank
you!</p>
