[vtkusers] How to extract vtkPolyData for each regions in vtkPolyDataConnectivyFilter?

[Andrej Gluhov]

I found several similar questions, but their problem to solve can not.

            vtkDICOMImageReader DicomReader = new vtkDICOMImageReader();
            DicomReader.SetFileName(m_strFilePath);
            DicomReader.Update();

            m_ContourFilter.SetInputConnection(DicomReader.GetOutputPort());
            m_ContourFilter.SetValue(0, -250);
            m_ContourFilter.Update();


m_ConnectivityFilter.SetInputConnection(m_ContourFilter.GetOutputPort());
            m_ConnectivityFilter.ScalarConnectivityOn();
            m_ConnectivityFilter.SetExtractionModeToSpecifiedRegions();
            m_ConnectivityFilter.Update();
            int regions =
m_ConnectivityFilter.GetNumberOfExtractedRegions();
            for (int i = 0; i < regions; i++)
            {
                m_ConnectivityFilter.AddSpecifiedRegion(i);
                m_ConnectivityFilter.Update();
                vtkPolyData PD = m_ConnectivityFilter.GetOutput();//here I
was hoping to see vtkPolyData for I-st region, but returned vtkPolyData of
m_contourfilter
            }
