Each ray has a magnitude and angle. A light field is the set of light rays flowing through a point, surface or volume from every direction. It approximately represents how light travels in physical space from a [[ray optics]] perspective. It is also known as a radiance field.+
A '''light field''' is a method of representing [[light]] that keeps track of the angle of each ray of light. It can be a volume of light treated as a set of [[ray]]s, or a flat surface through which different angled light travels. It is a set of rays with coordinate origin.

A light field can be displayed using a [[light field display]], which is a type of [[multifocal display]].
