This application relates generally to parallel computer processing, and more specifically, to parallel processing within a rendering engine via parallel scene graphs. One or more parallel scene graphs or parallel data graphs may be provided to a rendering engine. The rendering engine may identify dependencies within the parallel data structures and process, in parallel, one or more aspects of a the parallel data structure.

Parallel rendering engine

Methods and systems for generating three-dimensional (3D) images, 3D light field (LF) cameras and 3D photographs are provided. Light representing a scene is directed through a lens module coupled to an imaging sensor. The lens module includes: a surface having a slit-shaped aperture and a cylindrical lens array positioned along an optical axis of the imaging sensor. A longitudinal direction of the slit-shaped aperture is arranged orthogonal to a cylindrical axis of the cylindrical lens array. The light directed through the lens module is captured by the imaging sensor to form a 3D LF image. A 3D photograph includes a 3D LF printed image of the scene and a cylindrical lens array disposed on the printed image, such that the combination of 3D LF printed image and the cylindrical lens array forms a 3D stereoscopic image.

3-D light field camera and photography method

Techniques are disclosed for synthesizing depth of field effects in a digital image using ray tracing approximation. For each target pixel in the image, an aperture-shaped kernel is centered about a reference pixel. A cone of rays is traced through the aperture toward the image scene. The trajectory of the rays and the intersections between the rays and objects in the scene are approximated for a given scene depth, focal depth and aperture shape. The color of the pixel lying at the intersection, which may be offset from the target pixel, is sampled. This sampling process is repeated for several apertures bounding the target pixel, where each aperture is centered about a different reference pixel. The resulting color of the target pixel is acquired by integrating the colors of the pixels at each of the resulting intersections.
