Often, even games that have the option of first-person and third-person views, like the 3D The Elder Scrolls and Fallout games, will render the player character model in third-person but have it disappear in first-person.Īnother reason is that most GPUs and graphics APIs tend to clip geometry that's closer to the edge of the screen, hence the reason why in most cases using the same third-person model for a first-person camera would result in visual artifacts.
However, as hardware has become more powerful and software more sophisticated, this trope can become particularly jarring. Also, many older raycasting engines had to purposefully limit vertical camera rotation to well under ±45° in order to minimize perspective distortion artifacts. In early games, this was considered an Acceptable Breaks from Reality, as rendering something that wasn't in view the majority of the time would be a waste of limited hardware resources. In some cases, the player's physical body might never actually be modeled or tracked in-game. As far as the game engine is concerned, the player's viewpoint is just a camera. The game engine is built so that you are essentially just flying a camera around, with animated arms being "painted" on the screen that only you can see. This is because, from a technical perspective, you are. For the most part, it seems like the player might as well be a ghost. Walking up to a door, when you press the "open" button on the controller, nothing seems to happen in-game the door just magically opens up. You never see yourself in any mirrors or reflective surfaces. You don't cast a shadow, even if NPCs do. Further, you seem to have a curious lack of interaction with the environment: water is undisturbed by your steps, and walking through snow/mud leaves no footprints. Rather, your whole body seems to rotate with your view, making it look like you're not touching the ground at all. Looking down, you don't see your torso or legs. Instead of feeling like you're actually there, in the game, you almost feel instead like you're simply controlling a flying RC helicopter with a camera attached to it, or driving a robot on tank treads that has a two-way TV screen for a face.įor example, you see your arms holding the gun in front of you, but everything else about your body seems non-existent. In many First-Person Shooters you might notice that something odd about your character: you don't seem to have much in the way of a bodily presence.
