When viewing 3D data, Paraview defaults to just showing the outline of
the box.  There will be a drop-down menu near the top with the word
"Outline".  Click on that and change it so "Surface".  Then click on
the drop-down menu with "Solid Color" and change it to whatever you
like.

If you are running a binary, then there is no source.  You have to
build Gale from source in order to modify it.  The current release is
hard-coded to look in the current directory for "ascii_topo".  Because
of oddities with MPI, it may not be obvious what the current directory
is.  You can find out by running the cookbooks.  It should be the
directory where the "output/" directory is.
