FOVO: A new 3D rendering technique based on human vision
&quot;emulating human vision&quot; is a distraction here. If you have a flat 22 inch 16:10 display that you view from a 1m distance, dead centre, then the most natural way to render is to use linear projection with a FOV of ~26 degrees, which is absolutely tiny. But this matches the same view as if you were looking out a window the same size of your display.<p>Since such a tiny FOV is impractical, any rendering that wants to cover more FOV has to distort the view some way. There will be regions on the screen with more or less distortions, this becomes a trade-off. Arguably linear projection with a large FOV does a poor job at this.<p>I also wonder if there are projection techniques that specifically optimize for curved screens.
