We propose a display for stereoscopically representing an arbitrary object that is responsive to an arbitrary physical illumination source in the display environment. Our scheme is based on the eight-dimensional reflectance field, which contains angular and spatial information of incoming and outgoing light rays of an object, and is also known as the bidirectional scattering surface reflectance distribution function (BSSRDF). This system is composed of an integral photography unit, an integral display unit, and a processor connecting these units. The concept was demonstrated experimentally. In the demonstrations, a stereoscopically represented object responded to changes in physical illumination coming toward the display.
