Description: The Field of View (FOV) refers to the extent of the observable world that can be seen at any given moment. In computer graphics, FOV is a crucial parameter that determines how much of the virtual environment is displayed on the screen. This concept is fundamental in creating immersive visual experiences, as it affects the user’s perception of scale and depth in three-dimensional space. A wider FOV allows for more of the environment to be seen, which can be beneficial in various applications, such as video games, simulations, and virtual reality experiences, where situational awareness is key. Conversely, a narrower FOV can be used to focus the viewer’s attention on a specific area, creating a zoom effect or increasing the sense of intimacy. The choice of FOV also influences visual distortion; an excessively wide FOV can cause barrel effects, while a very narrow FOV may result in an unnatural viewing experience. In summary, the Field of View is an essential element in computer graphics that directly impacts how users interact with and perceive virtual environments.
