Hi Axel, thanks for the reply.
After you suggested to look at xsf I actually converted the VASP file to
xsf and I run against into the same problem: points are fine but
surfaces are not.
I do not know how VMD works internally so this might be a stupid
question: could it be that VMD does not like data provided in a
non-orthorhombic grid when drawing the surfaces? That is, not only the
lattice is (in my case) hexagonal, but also the grid where the charge
density is given.
If the solution is too complicated I can always write a script to
convert to an orthorhombic grid through interpolation.
Many thanks,
Miguel
