<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I have a tetrahedral mesh, in an
unstructured grid, and now i want to have the edges of the
tetrahedrons.</FONT></DIV>
<DIV><FONT face=Arial size=2> So I use vtkExtractEdges, but it
seems that the pointIds of the edges do not correspond to the vertices in the
original mesh.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So does anyone know a way to extract edges (merge
duplicate edges) and keep the pointset like in the original mesh?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Ideally i would like to have links from my
tetrahedrons to its faces, and from the faces to their edges and from the edges
to the points, but that would be to much propably...</FONT></DIV>
