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.

Abstract: A method, computer readable medium, and system are disclosed for adjusting an angular sampling rate during rendering. The method includes the steps of determining a location of a gaze within a displayed scene, and adjusting, during a rendering of the scene, an angular sampling rate used to render at least a portion of the scene, based on the location of the gaze within the displayed scene.

Abstract: A method, computer readable medium, and system are disclosed for generating mixed-primary data for display. The method includes the steps of receiving a source image that includes a plurality of pixels, dividing the source image into a plurality of blocks, analyzing the source image based on an image decomposition algorithm, encoding chroma information and modulation information to generate a video signal, and transmitting the video signal to a mixed-primary display. The chroma information and modulation information correspond with two or more mixed-primary color components and are generated by the image decomposition algorithm to minimize error between a reproduced image and the source image. The two or more mixed-primary colors selected for each block of the source image are not limited to any particular set of colors and each mixed-primary color component may be selected from any color capable of being reproduced by the mixed-primary display.
