ABSTRACT
An ideal display system for science and commerce would deliver the complete spectral, spatial, directional, and temporal distribution of light rays, as if these rays arose from a real 3D scene. The full radiometric description of light rays in the 3D scene is called the “light field” (Gershun, 1939). For vision science, the simplified and related representation is the irradiance the scene produces at the cornea-this is the only part of the scene radiance that the retina encodes. The complete radiometric description of the rays at the cornea, sometimes referred to as the plenoptic function (Adelson and Bergen, 1991), specifies the rate of incident photons from every direction at each point in the pupil plane. To achieve an accurate dynamic reproduction of a scene, the plenoptic function must change as the head and eyes move.
