Blinky – Exploring peripheral vision in games (using Quake)

Whoah, this is awesome. I was arguing with a friend earlier saying that the crazy stretching in the screen corners with standard rectilinear projections were awful. His argument was that the rectilinear projection preserves straight lines. I think the comparison was a fisheye projection, which at an extreme is also not great.

It looks like the Pannini projection here also preserves (some) straight lines though. I feel vindicated.

What I always wondered though, is what projection do human eyes really receive data from? Most illustrations show rectilinear projections, but I assume our eyes are closer to fish eyes than cameras, or at least are somewhere in the middle.

One of the first games I played on my new GPU was Minecraft with all the Mods and Shaders; when I got a VR headset, one of the first games I tried, also Minecraft; so when I read about the panini projection, you can guess what I went searching for. They even cite Blinky in their README: https://github.com/shaunlebron/flex-fov/blob/master/README.m...
