>FOV above 180
What are you, an alien? Why the fuck would you ever play a game like that?
a simple solution is using multiple cameras (three frustrums) and splice them into a panorama. id probably look up how panoramic software works in cameras to research it.
Not really for games but for a fisheye effect
This can also help simulating what a widescreen monitor can look like on low end PCs>>20516
Yeah I’ve heard of that technique though it’s typical you would actually use a double sideded reflective sphere and parent that to the original camera to create the illusion of wide eyed vision
Doom (original) used to let you play the game in multiplayer with yourself and set up multiple cameras on one player to display across three different monitors for a roughly 270 degree view.
amusingm but that's literally what you'd do.
Host a network game and then have two other players join with particular command line options to make them camera view left and camera view right for a particular player.
