I'm trying to use a 4D/35 Iris running under Irix 4.0.5 to generate an
out-of-window display for a flight simulator.  I'm having trouble trying
to relate the angles that define the aircraft's orientation with the
parameters of the "lookat" command.  Specifically, there's an argument
to lookat called "twist" that defines the angle of twist about the line
of sight.  I haven't for the life of me been able to figure out what
this variable really is, and how it relates to other variables I do know.
Does anybody out there have any experience using this command?  Any help
would be appreciated.

Thanks!
