Thanks for your help. I tried to put your code after my_polyData->RemoveDeletedCells();<br>
Unfortunately It doesn't work.<br>
I tried to delete lot of cells, they are never really removed.<br>
<br>
My VTK version is 5.2, does it matter?<br>

Hi all,<br>
<br>
I get a polydata volume with a vtkContourFilter and a<br>
vtkWindowSincPolyDataFilter.<br>
Some cells are not connected to the largest volume. They seem to<br>
be 'on' the mesh but have no vertice in common.<br>
<br>
I tried the filters vtkCleanPolyData and<br>
vtkPolyDataConnectivityFilter, but most of my unconnected cells<br>
are not removed.<br>
Finally, I tried to delete them 'manually', but nothing happens.<br>
<br>
How can I really remove my unconnected cells?<br>
<br>
Any help is appreciated, thanks!<br>
<br>
<br>
// generate my volume<br>
my_vtkWindowSincPolyDataFilter->SetInputConnection(my_vtkContourFilter->GetOutputPort());<br>
<br>
// no effect on my cells<br>
my_vtkCleanPolyData->SetInputConnection(my_vtkWindowSincPolyDataFilter->GetOutputPort());<br>
<br>
my_vtkCleanPolyData->PointMergingOn();<br>
my_vtkPolyDataConnectivityFilter->SetInputConnection(my_vtkContourFilter->GetOutputPort());<br>
my_vtkPolyDataConnectivityFilter->SetExtractionModeToLargestRegion();<br>
// manual remove<br>
my_vtkPolyDataConnectivityFilter->Update();<br>
my_polyData = my_vtkPolyDataConnectivityFilter->GetOutput();<br>
for(int i = 0; i < n; i++){<br>
my_polyData->DeleteCell(cellsToRemove[i]);<br>
}<br>
my_polyData->RemoveDeletedCells();<br>
<br>
