[vtkusers] Volume Rendering Problem in ActiViz 6.2

[Matias Montroull]

Hi,

I was using ActiVIz 5.8 and this code below was working just fine:
Now, I've installed the 6.2 version and the vtkCleanPolyData object is null
for some reason..
Has anything changed in Volume reconstruction from a Dicom Series from
version to version?

Thanks,

 vtkDICOMImageReader readerdicom = new vtkDICOMImageReader();

readerdicom.SetDirectoryName(path_directorio_imagenes_originales);
            double origen_X = -pixelspacing_X * (img[0].Width) / 2;
            double origen_Y = -pixelspacing_Y * (img[0].Height) / 2;
            readerdicom.SetDataOrigin(origen_X, origen_Y, -Z_max);
            readerdicom.Update();

            //Filtro para dar vuelta la imagen
            vtkImageReslice reslice = new vtkImageReslice();
            reslice.SetResliceAxesDirectionCosines(-1, 0, 0, 0, 1, 0, 0, 0,
-1);
            reslice.SetInputConnection(readerdicom.GetOutputPort());
            reslice.Update();

            //Filtro para extraer la piel (por ISOValue)
            vtkMarchingCubes skinextractor = vtkMarchingCubes.New();
            skinextractor.SetInputConnection(reslice.GetOutputPort());
            skinextractor.SetValue(1, umbral);

            //Filtro para quedarnos solamente con el contorno (visual)
            vtkPolyDataConnectivityFilter contornos = new
vtkPolyDataConnectivityFilter();
            contornos.SetInputConnection(skinextractor.GetOutputPort());
            contornos.SetExtractionModeToLargestRegion();
            contornos.SetColorRegions(1);

            //Filtro para remover los puntos que no son del contorno y
guardarlos en la instancia POIs_3D
            vtkCleanPolyData removepoints = new vtkCleanPolyData();
            removepoints.SetInputData(contornos.GetOutput());
            removepoints.Update();
            vtkPoints puntos_contorno = new vtkPoints();
            puntos_contorno = removepoints.GetOutput().GetPoints();
