Table fog effect summary

Fog is a special effect that is used to blend a scene into a predefined color to give the impression that "fog" is present in the scene. Fog is usually implemented as it appears in the physical world. The farther objects are, the more they are obscured by fog. Objects that are close to the observer are clearer.

Table fog, also called pixel fog, is calculated independent of vertices. Ideally, fog is calculated on a pixel basis, but many device drivers emulate this feature in software with vertex fog values. It is called table fog because traditionally tables have been used to look up fog values. The RIVA 128, RIVA128ZX and the RIVA TNT all emulate table fog using vertex based fog. The GeForce 256 supports table fog in hardware.[1][2]
