Light field display

A system for displaying a light field to a set of viewers, the light field based on a 3D model, the set of viewers comprising at least one viewer, the system comprising:

• (i) a set of computing devices, the set of computing devices comprising at least one computing device;
• (ii) a light field display device coupled to the set of computing devices, the light field display device comprising a first plurality of spatially distributed display elements, each display element adapted to emit, in each of a plurality of output directions, an output beam of light;
• and
• (iii) a set of tracking cameras coupled to the computing device, the set of tracking cameras comprising at least one tracking camera;
• wherein the set of computing devices is configured to determine, via at least one image captured via the set of tracking cameras, a pair of viewpoints, relative to the display device, of a pair of eyes of each viewer of the set of viewers;
• and to render, for each eye viewpoint and each of a second plurality of the first plurality of display elements, a partial view image representing a view of the 3D model from the eye viewpoint through the display element, the partial view image comprising a set of radiance samples, each radiance sample associated with a different one of the output directions through the display element;
• and
• wherein each display element of the second plurality of display elements is adapted to emit, based on the set of partial view images rendered for the display element, each output beam of light with a radiance based on the radiance sample associated with the corresponding output direction.
