I'm not sure what to suggest here, short of suggesting that you hack
the Geomview code to allow specifying an arbitrary image for the
camera background.

The SGI version of Geomview will run several orders of magnitude
faster than the X version does, especially with a remote display.  In
addition to increased speed, the SGI version is actually better than
the X version --- at present the X version draws things (e.g.
overlapping polygons) incorrectly in many cases.  We're currently
working on fixing that, but fixing it will slow the X version down
even more.  In general, if you have an SGI, use it!
