<P>I use vtkSmoothPolyDataFilter to smooth a triangle mesh, and soon i find that
the smoothed mesh can contain holes when the Feature Angle and Edge Angle are
set to relatively big values( in my program, Feature Angle=120 and Edge
Angle=90). I don't know why this can occur. Anyone can help me? </P>
<P>Thanks!</P></BODY></HTML>
