This brings us to the techie debate over what is the dpi of human sight, with the idea that, once you have a screen with a greater dpi, then the human eye won't be able to tell the difference between a created image and real life.
And the answer is: it's complicated. Human sight is very HD in a narrow circular field of view, and everything else is low rez. However, we see more than with our eyes, we see with our brain. And our brain is great at 'computing' and 'rendering' all the stuff our eyes really don't catch at HD. When we blink or dart our eyes back and forth, our brain creates a compensating image that fills in what would be a blur or blackness. We think what's in our peripheral vision is high rez, when, in fact, it's not. And that's because our brain paints in details we're not really seeing anymore.
And we have excellent color vision and 3D vision (both assembled by our brains and not what we actually see). And 3D vision is more than binocular images superimposed, it's the change of lighting, the blurring of things out of the field of focus, the little glints of light, the multiple shadings of light bouncing all over the place, it's seeing the minute translucence of an object (which often puts computer rendered skin in the uncanny valley if there's no translucence).
So, yes, in order for what's projected on the screen in Smuggler's Run to look 'real', it has to take into account all those effects that fool the eye and what our brains use to decode what we see as real. A pre-rendered ultra high def image like in Flight of Passage can do that. A rendered-on-the-fly real-time image requires huge super-powered computing and several of the highest end graphics cards along with a ultra high-def projector and everything in sync with movement. And Smuggler's Run will have all that. The kind of gorgeous pre-rendered CGI done on the fly.
