Why High FOV Sucks – Fixing It with Panini Projection

Unreal supports Panini out of the box, but very few games seem to use it or any other alternative projection.

HYPER DEMON may be the best known and most extreme exception, it renders 180 degrees in front of you, then renders 180 degrees behind you as a red-tinted overlay, giving full 360 degree awareness if you can wrap your brain around it.

There is also FOVO Dynamic Projection which claims projection like human vision. They have videos showing the projection in action in games https://www.fovotec.com/gaming

I would love for us to move past the idea that non-pinhole projections have "distortion", and we should strive to remove this "distortion" by reprojecting stuff to pinhole models. In practice, ALL projections distort straight lines and/or shapes and/or sizes, so if you use the pinhole projection everywhere, your images look like crap (see iphone wide-lens camera output for instance). Most of the normal non-pinhole projection functions work fine for wide lenses, while behaving like a pinhole lens with long lenses: https://en.wikipedia.org/wiki/Fisheye_lens#Mapping_function

Nice! I wanted to do this sort of thing when I was playing around with 3D game programming in the late 90s / early 2000s, to capture how a wider FOV looks in movies. Alas, computers were too slow and I was too inexperienced anyway.

I find it funny people play on the highest fov in first person shooters to their own detriment.
They think the higher fov is a pure win as it allows them to see more but in reality it is a tradeoff making targets in front of them smaller.
