[Paraview] [vtm] file formats

[Berk Geveci]

Hi Soren,

If you checkout VTKData from CVS, there is an example file there. It
is VTKData/Data/chombo3d/chombo3d.vtm. Let me know if have any
questions about the format once you look at the example. You will have
to provide dummy values for cells that are overlapped by higher
levels. I would recommend using values from higher levels if possible.
There are tools in paraview that let you explore a certain level. In
this case, it would be useful to have valid values even on cells that
are covered by higher order ones. Other than that, if you follow the
example of  chombo3d.vtm, paraview will automatically detect overlaps
and hide the cells that have higher level versions. In order for this
to work properly, you have to make sure that you specify amr_box for
each block properly.
