1. A method for rendering a light field that comprises a plurality of elemental images arranged in a grid, the method comprising:
generating, by a processor, for each elemental image of the plurality of elemental images, components of the light field corresponding to that elemental image by:
projecting rays from a viewpoint positioned at a lateral offset from a first side of a spatial light modulator (SLM) to form an elemental view frustum within a three-dimensional scene; and
rendering objects within the elemental view frustum to generate components of the elemental image,
wherein each elemental image of the plurality of elemental images corresponds to a holographic element (hogel) associated with one or more picture elements (pixels) of the SLM, and wherein the SLM is divided into a plurality of hogels having size wh and the lateral offset is calculated based on the size wh.
