    BUG: Fixed error in area-weighted normal · 67122e84
    Cory Quammen authored
    When the closest point on a surface to a test point is on an edge, the
    area-weighted normal is the average of the normals of the faces
    adjacent to the edge. The contribution from one of the faces was being
    added twice, producing the incorrect area-weighted normal. This
    resulted in the wrong sign for the signed distance in some cases.
    This patch fixes the error.
    
    Changed TestImplicitPolyDataDistance.cxx to fail prior to this change
    and pass after the change. The previous test exercised
    vtkImplicityPolyDataDistance but did not check the results. The new
    test checks against a baseline.
