Is there a kind of AND-filter for vtkPolyData-meshes which I could use to extract/select coincident points/cells of two meshes?<br>
<br>
Thanks for any hints or help<br>

Dear mailing list members,<br>
<br>
<br>
There are many filters in VTK to clean/merge coincident points but I<br>
could not find a single filter that extracts/selects coincident<br>
points/cells.<br>
I would need it to extract the sub-mesh of two or more<br>
vtkPolyData-meshes where these meshes overlap, e.g. when a<br>
vtkDiscreteMarchingCubes surface is generated of two or more labels that<br>
directly touch each other in voxel space.<br>
Or is there a way to just generate a mesh of the area where both labels<br>
touch?<br>
<br>
Any help or hints are very much appreciated<br>
Roman<br>
