        <p>Hi VTK Users,</p>
        <p>I'm currently using vtkRuledSurfaceFilter to convert a
          sequence of contours into a surface. The problem is that if
          two contours happen to be on the same plane the surface filter
          will join them resulting in artefacts.
          <br>
        </p>
        <p>Any suggestions on how to deal with this?</p>
