Sorry about that--I forgot that the Starbase Display List software is not
a standard product on every HP machine.  One solution would be to rip out
all the interactive code in lookat.c (mouse calls, and associated loops to
refresh the segment), all SBDL *_segment() code, and to perform the 
lights setup in draw_object() immediately upon encountering a "f" command
in the *.nff files (not fool-proof, but all my NFF generators from the SPD
package do not output any "f" (fill color) commands until all lights are
output).

Alternately, wait a few days and I'll post my lookonce.c code, which does
not have any sbdl calls (it's not interactive, though).

BTW, if you're doing anything 3D & interactive, you should seriously consider
getting the SBDL package, as it'll save you a lot of reinventing the wheel.
