[vtkusers] vtkSelectEnclosedPoints.Update() doesn't finish

[Sam]

Hello,

I'm using vtkSelectEnclosedPoints to check how many voxels from my model
exist in my image.  However, the update function of vtkSelectEnclosedPoints
never returns.  Please help, here is my pipeline:

            //Read in Model PolyData vtk file.
            vtkPolyDataReader polyDataReader = new vtkPolyDataReader();
            polyDataReader.SetFileName("C:\\DICOModel\\OriginalModel.vtk");
            polyDataReader.Update();
            vtkPolyData model = polyDataReader.GetOutput();

            //Read in MRI Volume
            itkImageBase imageInput = ImageType.New();
            imageInput.ReadSeries("C:\\DICOMVolume", "*.dcm");

            //Convert itkImagebase into a vtkImageData
            vtkImageData dicomImageData = new vtkImageData();
            itkImageToVTKImageFilter_IUC3 convertITKToVTK =
itkImageToVTKImageFilter_IUC3.New();
            convertITKToVTK.SetInput(imageInput);
            convertITKToVTK.Update();
            
            dicomImageData = convertITKToVTK.GetOutput();

            vtkSelectEnclosedPoints vtkModelRegion = new
vtkSelectEnclosedPoints();
            vtkModelRegion.SetInput(dicomImageData);
            //vtkModelRegion.SetCheckSurface(1);
            vtkModelRegion.SetSurface(model);
            vtkModelRegion.Update();   //Never returns, I let it run for 20
minutes and stopped it.
