Abstract: In one embodiment, a method includes receiving a source image and its associated parameters from each of multiple image sources, associating each of the source images with a layer in a range of layers based on the parameters associated with the source images, the range of layers specifying a composition layering order of the source images, generating a corresponding customized distortion mesh for each particular source image in the source images based on the parameters associated with the particular source image and at least a portion of the parameters associated with each of the source images that is associated with any layer preceding a layer associated with the particular source image, modifying each of the source images using the corresponding customized distortion mesh, generate a composite image using the modified source images, and display the composite image as a frame in a video.

Abstract: An XR device includes a display device, a lens, and programs. The programs are stored in memory and configured to be executed by processors. Moreover, the programs include instructions for determining an HPPD metric for the XR device based on characteristics of the display device and the lens. The programs also include instructions for receiving data regarding a size and a location of visual XR content from an XR application running on the XR device. Additionally, the programs include instructions for determining an RPPD metric for the visual XR content based on the data. Further, the programs include instructions for determining a recommended resolution for rendering the visual XR content based on the HPPD metric and the RPPD metric. Moreover, the programs include instructions for transmitting the recommended resolution to the XR application, where the XR application is configured to render the visual XR content using the recommended resolution.

Abstract: In particular embodiments, the disclosure provides a method comprising: rendering, on a graphics processing unit (GPU), a low-resolution image associated with a scene, the low-resolution image having a resolution that is lower than a target resolution; transmitting a version of the low-resolution image to a neural accelerator; processing, on the neural accelerator, the version of the low-resolution image using a trained machine-learning model, thereby outputting a plurality of control parameters; transmitting the control parameters from the neural accelerator to the GPU; processing, on the GPU, the low-resolution image and the control parameters to construct a high-resolution image having the target resolution, wherein the GPU is programmed to determine a plurality of pixel weights for performing an interpolation using the control parameters; and outputting the high-resolution image.

Abstract: In one embodiment, a method includes accessing a first image corresponding to a first frame of a video stream, rendering a first area of a second image corresponding to a second frame of the video stream, generating a second area of the second image corresponding to the second frame of the video stream by re-projecting the second area of the first image according to one or more warping parameters, and constructing the second image corresponding to the second frame by compositing the rendered first area and the generated second area of the second image.
In another embodiment, a method includes an operating system receiving a set of data associated with an object from a first application, storing the set of data on the operating system, receiving a command to share the object with a second application, and allowing the second application to access the portion of the data associated with the object that it needs.
