When I was in video games, I wrote a 3d game. It was on a color
vector system. I split the screen into left & right images.
The images were integrated by means of a parascope mirror
system. Objects in each half were draw in perspective.
Thus 3 ques were used: perspective, triangulation, & motion.
The game was first person: driving along a road & shooting
things. 3d explosions were like totally gnarly.
Most people enjoyed the effect. A few actually DID NOT
perceive the 3d, even though their eyes superimposed
the 2 halves correctly. Beats me how they missed it.

(I should acknowledge my co author: Earl Stratton).
