Graphics system configured to implement fogging based on radial distances

摘要

A graphics system configured to implement fogging according to an improved method based on radial distances. The amount of fog applied varies based on a spherical or radial distance from an object to a viewpoint. In another embodiment, the amount of fogging applied may depend on the cylindrical distance form an object to a viewpoint. Fogging cylinders or spheres may be used to define fogging regions where the amount of fogging is applied according to different mathematical functions.
