I have red and blue flashlights, with which, I will project red/blue light onto the viewing screen.
I have bad news for you. I surmise that your optics textbook was written by Plato, and unfortunately some of his ideas have been found to be wrong.
How, exactly, are you going to project this red/blue light?

I believe I stated how in my original query, but I have rephrased it above. I don't believe, however, that Plato, or any of his compatriots, ever discussed optics.

Stephen,
the way 3-D movies and the accompanying glasses work is that two images are shot from slightly different perspectives. They are then given a colour shift so that when viewed through the tinted glasses, the filtering of the tint ensures that the image intended for the left eye is seen by it, and similarly for the right. Hence the illusion of binocular viewing of a 3D image.
Bathing the image in two colours of light will only suffice to make it look ugly.
Brian's point about Plato was that one of the dominant theories of ancient Greek optics was that vision is accomplished via emanations from the eye. He, quite humoursly, was pointing out that your plan seems to overlook that the 3D effect is created by rays entering your eye, rather than some coming out from it.
As it turns out, the theory of optics was a lively branch of ancient Greek thought. It likely goes back to at least the generation before Socrates if not all the way to Thales.
Best to all,
