[vtkusers] Why triangle not appear

[Ali Habib]

Dear All,

why vtktraingle, vtkstripper or vtkdatasettrianglefilter, not give any
effect , by another meaning it not give effect by divide the volume to
triangles and  display it

I used many of the above filters and the output is the same without applying
them

I read dicom and apply marchingcube then one of those filters some of the
codes I used, and the output attached , how to make them be displayed


            vtkMarchingCubes skinExtractor =  vtkMarchingCubes::New();

            skinExtractor->GetOutput()->ReleaseDataFlagOff();

            skinExtractor->SetInputConnection(VIG->GetOutputPort());

            skinExtractor->SetValue(0, 500);

            skinExtractor->ComputeGradientsOn();

            skinExtractor->Update();



            vtkTriangleFilter VTF =  vtkTriangleFilter::New();

            VTF->SetInputConnection(skinExtractor->GetOutputPort());

            VTF->GetOutput()->ReleaseDataFlagOff();

            VTF->Update();

            // Create Mapper

           vtkDataSetMapper skinMapper =  vtkDataSetMapper::New();

           skinMapper->SetInputConnection(stripper->GetOutputPort());
