Hi, this is Wayne again with a topic “Field of View (FoV) in Video Games as Fast As Possible”.
Field of view in the context of video games is the total angular extent of any scene that can be viewed on the screen at any given moment. Got that great thanks for watching give us a like or dislike share comments? Okay, maybe i should explain it a bit better than that now, your own eyes, assuming you’re human, can see almost 180 degrees of the world out in front of you. But a monitor huge enough to take up your entire field of vision would be really really impractical. For a variety of obvious reasons, so if you’re sitting a normal distance away from a reasonably sized screen, it will take up something like 30 or 40 horizontal degrees of your vision. But if the camera within a first person, video game is set up to show only 40 degrees of the game world. Well, that’s a bit of a problem. You’Ve got no peripheral vision. Some first person, video games, that i’ve played certainly do suffer from this tunnel vision effect, which is pretty terrible when there are people shooting at you that you can’t even see. Also, a narrower field of view causes many gamers to feel nauseated, while playing because camera movements are more exaggerated, alright, so here’s the other extreme now we’re on a gopro hero, 3 plus, which has something like a 170 degree, horizontal field of view. So, even if the screen you’re watching this on takes up only 40 degrees of your vision, you can still see 170 degrees in this scene here. This definitely solves the tunnel vision problem, but it’s not a perfect solution. First of all, everything on screen is now smaller and therefore more difficult to see. Secondly, with extremely wide angle views you get this funny sort of distortion that occurs around the edges of the scene.
So how do gamers solve this problem? One way is to add more screens, but then, of course, you have to go, buy more screens and maybe a monitor, stand and then maybe a better graphics card to help you render out all those pixels, but that’s an expensive way to go. Another option is to change the field of view or fov slider within the game, to whatever is most comfortable for you. However, some games don’t have this option, so why would a game developer leave that out? Well, one reason is the dreaded, cps or console port syndrome for a console game.
You’Re, usually going to be sitting farther away from the screen, so a narrower field of view looks and feels more natural, even if it does result in tunnel vision. It also requires less processing power. Widening the field of view puts more objects on screen, which makes the game more demanding for your little console to render so console games are often made without a field of view slider to optimize performance, and so the ported pc version. Sometimes doesn’t get one either and that’s a real shame. You know what else is a real shame, my lack of beard in this episode.
You see, i’ve received a number of really lovely comments, telling me to shave my beard off so because today’s video sponsor is dollar shave club.
