−A light field is a representation of a body of light with the magnitude and angle of light. It approximates how light travels in the real world. It is represented by a 3D grid (or 2D grid) of vectors that have both a magnitude and a direction. A light field can be full color or it can be black and white.
+A light field is a body of light treated as a set of rays, where each ray has a magnitude and angle. It approximates how light travels in the real world. It is represented by a 3D grid (or 2D grid) of vectors that have both a magnitude and a direction. A light field can be full color or it can be black and white.
A light field can be represented using a [[plenoptic function]].
