Abstract: Systems and methods described relate to the generation of image content. In order to provide for smoothing between sequential images, but avoid introducing lag into lighting effects, light information can be compared for regions between consecutive rendered frames. Shading can be performed and the results compared for tiles of pixels to compute gradient values, such as by using a single light sample for each tile. A filtering pass can be performed with respect to these gradients, and this filtered, lower-resolution grid version can be upscaled into a full resolution, screen-sized image and the gradients transformed into confidence values. These confidence values can be used to determine an extent to which to keep lighting data from the previous frame with respect to the current frame. For example, less lighting information can be used from the prior frame for a given pixel location if the confidence for that location is lower.

Abstract: Systems for, and methods of, computing gathers for processing on a SIMT processor. In one embodiment, the system includes: (1) a thread group creator executing on a processor and operable to assign ray traces pertaining to a single receiver to threads for execution by a SIMT processor and (2) a memory configured to contain at least some of the threads for execution by the SIMT processor.

Abstract: A cover is provided that is adapted to wrap around at least a portion of a child container such as a crib or play yard. The cover includes at least one fabric sheet having a surface area sufficient to cover substantially all of a top face of a mattress in the child container. The sheet includes at least one mattress fastener such as a sleeve or band that is operative to mount the sheet to the mattress. The cover also includes at least one panel connected to the sheet which wraps inner faces of the walls of the child container, which extends over the upper edges of the walls, and which extends over adjacent portions of the outer faces of the walls. The at least one panel includes at least one fastener component that is usable to fasten the cover adjacent the outer faces is of the child container.
