Abstract: In embodiments of the invention, a method may include displaying an array of slits using a first light-attenuating spatial light modulator, displaying a pre-filtered image using a second light-attenuating SLM by attenuating rays of light originating from a surrounding environment to synthesis a near-eye light field, where the rays of light pass through the first and second light-attenuating SLMs, and selectively blocking the rays of light originating from the surrounding environment using the array of slits to generate a virtual image in said near-eye light field.

Abstract: One embodiment of the invention sets forth a mechanism for interleaving consecutive display frames rendered at complementary reduced resolutions. The GPU driver configures a command stream associated with a frame received from a graphics application for reduced frame rendering. The command stream specifies a nominal resolution at which the frame should be rendered. The reduced resolution associated with the frame is determined based on the reduced resolution of an immediately preceding frame (i.e., the complementary reduced resolution), if one exists, or on GPU configuration information. The GPU driver then modifies the command stream to specify the reduced resolution. The GPU driver also inserts an upscale command sequence specifying the nominal resolution into the command stream. Once the command stream is configured in such a manner, the GPU driver transmits the command stream to the GPU for reduced rendering.

Abstract: Virtual reality (VR) displays are computer displays that present images or video in a manner that simulates a real experience for the viewer. In many cases, VR displays are implemented as head-mounted displays (HMDs) which provide a display in the line of sight of the user. Because current HMDs are composed of a display panel and magnifying lens with a gap therebetween, proper functioning of the HMDs limits their design to a box-like form factor, thereby negatively impacting both comfort and aesthetics. The present disclosure provides a different configuration for a virtual reality display which allows for improved comfort and aesthetics, including specifically at least one coherent light source, at least one holographic waveguide coupled to the at least one coherent light source to receive light therefrom, and at least one spatial light modulator coupled to the at least one holographic waveguide to modulate the light.

Abstract: The present invention facilitates efficient and effective image processing. A network can comprise: a first system configured to perform a first portion of lighting calculations for an image and combing results of the first portion of lighting calculations for the image with results of a second portion of lighting calculations; and a second system configured to perform the second portion of lighting calculations and forward the results of the second portion of the lighting calculations to the first system. The first and second portion of lighting calculations can be associated with indirect lighting calculations and direct lighting calculations respectively. The first system can be a client in a local location and the second system can be a server in a remote location (e.g., a cloud computing environment). The first system and second system can be in a cloud and a video is transmitted to a local system.

Abstract: In embodiments of the invention, an apparatus may include a display comprising a plurality of pixels and a computer system coupled with the display and operable to instruct the display to display images. The apparatus may further include an SLM array located adjacent to the display and comprising a plurality of SLMs, wherein the SLM array is operable to produce a light field by altering light emitted by the display to simulate an object that is in focus to an observer while the display and the SLM array are located within a near-eye range of the observer.

Abstract: Techniques are disclosed for tracing a ray within a parallel processing unit. A first thread receives a ray or a ray segment for tracing and identifies a first node within an acceleration structure associated with the ray, where the first node is associated with a volume of space traversed by the ray. The thread identifies the child nodes of the first node, where each child node is associated with a different sub-volume of space, and each sub-volume is associated with a corresponding ray segment. The thread determines that two or more nodes are associated with sub-volumes of space that intersect the ray segment. The thread selects one of these nodes for processing by the first thread and another for processing by a second thread. One advantage of the disclosed technique is that the threads in a thread group perform ray tracing more efficiently in that idle time is reduced.

Abstract: A method to drive a pixelated display of an electronic device arranged in sight of a user of the device. The method includes receiving a signal that encodes a display image, and controlling the pixelated display based on the signal to form the display image in addition to a latent image, the latent image being configured to illuminate an eye of the user with light of such characteristics as to be unnoticed by the user, but to reveal an orientation of the eye on reflection into a machine-vision system.
