[vtkusers] Remeshing/triangle regularization

[Henrik Westerberg]

Hello B.M.

I ran into this same problem myself. I found it easier to look for something
outside of VTK. I wanted to go an open-source route and found netgen to be 
suitable for my needs:

http://www.hpfem.jku.at/netgen/

It can take an stl surface from vtk and calculate a new surface and
a volume (tet) mesh as well. 

There are quite a few websites online giving links to software I can
only find one link right now in my bookmarks:

http://www.andrew.cmu.edu/user/sowen/software/tetrahedra.html

Without any more information about your requirements I can't really help.

There are plenty of pay-for software as well.

regards,

Henrik

Not directly. You can build a filter yourself though. I do it combining 
smoothing and employ distance function to project the nodes back to the 
original mesh (using vtkWarpFilter if I am not mistaken).
