I have been using object graphics to create a streamline display that
the user can rotate to find a nice viewing angle.
If I print that view to a PostScript file, though, I found no way so far
to get smooth lines. I rather end up with a pixelated rendering.
Is this the way it is supposed to work or am I missing something?

This is probably due to OG generating Encapsulated PostScript, while
DG generates PostScript, and EPS if you ask for it. I'm guessing that
your image application is treating the EPS file as a single object.
Maybe it has a feature/option to let you edit the EPS? If you know
enough PostScript, you might be able to edit the file to convert it
from EPS to PS or find a tool to do that. I've seen PS->EPS
converters.
