vtkDataSetSurfaceFilter and degenerate wedges
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkClipDataSetFilter can produce in some cases degenerate wedges, where two points collapse (this is thus a tatra). vtkDataSetSurfaceFitler is failing to show them properly.
As a temporarily solution, one can still use a vtkGeometryFilter followed by a vtkPolyDataMapper, instead of a vtkDataSetMapper (which use internally a vtkDataSetSurfaceFilter).
