[vtkusers] question about vtkPolyDataConnectivityFilter

[Anja Ende]

Hi everyone,

I am using vtkPolyDataConnectivityFilter as follows:

vtkContourFilter * contourFilter = vtkContourFilter::New();
contourFilter->SetInput(vtkDicomReader->GetOutput());
contourFilter->SetValue(0, 255);
	
vtkPolyDataConnectivityFilter * polyDataFilter =
vtkPolyDataConnectivityFilter::New();
polyDataFilter->SetInput(contourFilter->GetOutput());
polyDataFilter->SetScalarRange(255.0, 255.0);
polyDataFilter->Update();
	
int regions = polyDataFilter->GetNumberOfExtractedRegions();

Now what I want to do is iterate through all the regions and each of
the points in the region. However, I cannot figure out how to do this.
Anyone has any idea on how I can iterate through the regions and the
points?

Cheers,

Anja
