- 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!
