Hi David,
As far as I know, PyMOL is still using its own DX reading functions
(primarily ObjectMapDXStrToMap in layer2/ObjectMap.c if anyone's curious).
I don't think it would be too much work to get PyMOL to read regular.dx. As
far as I can tell, the only problem is that PyMOL is expecting the line that
starts with "object 3" to say "object 3 class array type double" instead of
"object 3 class array float".
As for regularskewed.dx, PyMOL *does* support non-orthogonal maps (see e.g.
http://www.mail-archive.com/pymol-users@lists.sourceforge.net/msg05870.html),
but I'm not sure that PyMOL's DX reader supports them directly.
I have not looked into the VMD plugins. If they support non-orthogonal DX
maps out of the box, that might be a quick and easy solution.
Cheers,
-Michael
