Help: Contour lines displayed discontinous

Development

If you are sure you want contour lines, please review the parameters passed to vtkContourFilter.

Here’s how I setup mine:

    vtkSmartPointer<vtkContourFilter> contourFilter = vtkSmartPointer<vtkContourFilter>::New();
    contourFilter->SetInputData( imageData );
    contourFilter->GenerateValues( 20, min, max); // (numContours, rangeStart, rangeEnd)
    contourFilter->Update();

Notice the importance of GenerateValues() which is missing in your code.

best,
