[vtkusers] Set the contour value from DicomReader

[Larcher Aurélie]

Hi all,

I try to set contour value to my Dicom Reader in order to generate skin
surface.

When I use filter like vtkMarchingContourFilter or vtkContourFilter with the
contour value 30, there is no result.

      vtkDICOMImageReader *colonneReader = vtkDICOMImageReader::New();

            colonneReader->SetDirectoryName("F:/Images/VDH/Dicom/");

            colonneReader->Update() ;

      vtkMarchingContourFilter *surfacePeau =
vtkMarchingContourFilter::New();

            surfacePeau->SetInputConnection(colonneReader->GetOutputPort());

            surfacePeau->SetValue(0,30);

Nevertheless, when I use vtkEdgePoints with the same contour value, I have
some result

vtkEdgePoints *surfacePeau = vtkEdgePoints::New();

            surfacePeau->SetInputConnection(colonneReader->GetOutputPort());

            surfacePeau->SetValue(30);

If I changed the contour value at 200, I obtain the same result with the 3
filters (with different appearance obviously).

Can you tell me what’s the problem and how can I generate skin surface with
vtkMarchingContourFilter or vtkContourFilter.

Thanks,

Aurélie
