Determine the stereo vision
There is still one more major item missing, before we can look at a computer display or plot and perceive it just as we see a real object, namely the stereo vision we experience with our two eyes. That too is now available, with software producing two colour-coded, polarized, or alternating images for left and right eyes, and a set of special glasses to merge them for the observer. In fact, this technology is very much in use by architects who wish to show off their latest creations to their (rich) clients and for doctor who wish to plan and rehearse microsurgery of the brain or heart.
