Abstract:
A method for rendering a light field comprises projecting rays from a viewpoint positioned at a first side of a spatial light modulator (SLM) to a clipping plane positioned at an opposing side of the SLM to form an elemental view frustum within a three-dimensional scene and rendering objects within the elemental view frustum to generate components of a first elemental image for the first elemental region. The SLM may include a tiled array of non-overlapping elemental regions and a top edge and a bottom edge of a first elemental region of the non-overlapping elemental regions are intersected by the rays to form the elemental view frustum. Furthermore, the light field may include the first elemental image and additional elemental images corresponding to the array of elemental regions and each one of the additional elemental images is rendered using an additional elemental view frustum.
