What is distance fog?

Distance fog is also known as atmospheric fog, volumetric fog, or depth fog. It is a visual effect used in video games, movies, and animation to simulate fog or mist that decreases visibility and creates depth in a scene.

Distance fog is typically achieved through a rendering technique that layers semi-transparent layers of fog in front of objects as they recede into the distance. This creates the illusion of particles in the air, which absorb and reflect light, wrapping objects in a hazy veil.

Distance fog has been used in video games to create intense and dramatic scenes, simulate weather conditions such as rain or snow, and improve spatial awareness by adding depth to an environment. It can also be used to hide or reveal objects, creating suspense and tension in a game or movie.

In some cases, distance fog may be used sparingly to enhance the mood of a scene, while in other cases, it may be used excessively to create a dream-like or surreal atmosphere.

Overall, distance fog is an essential element in creating immersive visual experiences, adding depth and realism to virtual environments.
