HUD's in performer

I have been working on a distributed interactive flight simulator here
at AFIT and I used GL calls in a draw call back. The call back is setup
to be called after our aircraft model is drawn. All the vertices in the
bgnline();...endline(); calls are defined in our aircraft model space. We
use a Polhemeus Fastrack with this thing, so as an added bonus, the HUD
changes perspective with the rest of the simulation if the pilot moves
his head.
The text on the HUD was a little more difficult, but I ended making a
vector based font class which works well. There is not much of a
performance hit with this scheme if as many of the vertices as possible
are defined as static.
