Extracting Lines from Polydata

[Will Schroeder]

Hi Mykola-

Try using vtkGeometryFilter and using the "CellClipping" functionality. Something like:

vtkGeometryFilter *gf = vtkGeometryFilter::New();
gf->SetInput(yourPolyData);
gf->CellClippingOn();
gf->SetCellMinimum(n);
gf->SetCellMaximum(m);

Right now it only works for contiguous cell ids.

Will
