<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I have a Tetrahedron Mesh and I need to smooth it.
However, the smoothing algorithm such as laplacian cannot guarantee that the
topology is not changed. Could anybody give me some advice about the
algorithm which can smooth the mesh and remain the original
topology?</FONT></DIV>
