A separate Silicon Graphics Workstation was chosen to host the realtime
display system. 3-D models of various missiles and target ships were displayed
using Open-GL.
Multiple viewpoints were simultaneously displayed, including
ship, missile, and gods-eye (overhead) views. This was easily able to keep up
with the 15 frames-per-second minimum refresh requirement. All coding was done
using the C++ language.
The position, orientation, and velocity of the missile
and the ship were sent to the display system using TCP/IP messages sent over
a 100base-TX ethernet, with the display system acting as a server. This design
allowed for preliminary remote integration of the display system over the Internet,
well before physical delivery, and proved invaluable in finding and correcting
interface problems. The payoff came at delivery, when the full-up integration
took less than a day.
