"Irides also does this with a technique called “likelyhood-based foveation” that renders higher quality parts of an image and ‘gracefully degrades’ others, all based on where the user is likely to look. It also uses a spherical mesh for said image. In a sense, this sort of mimics the human eye, and offers the user lower latency and higher quality at the same time."
This is interesting part. I remember back in 80s reading about certain, IIRC Air Force combat training simulator doing something similar - just rendering at higher quality what you're directly looking at.
I made thread about it couple years back wondering if this is viable way to do with games and TVs, I think we came to conclusion TV might be too small for such approach, but VR seems like perfect candidate.
