ambient lighting

Light that comes from all directions. Contrast with "directional lighting," which is made up of a light source with parallel light rays that do not diminish with distance. Also, contrast with "positional lighting," in which the rays are not parallel, but diminish in intensity from the source.


Primary Light Sources
Ambient lighting comes from all directions, while directional and positional lighting come from one source. (Image courtesy of Intergraph Computer Systems.)
