Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine an eye-buffer including one or more bounding boxes associated with rendered content in a frame. The apparatus can also generate an atlas based on the eye-buffer, the atlas including one or more patches associated with the one or more bounding boxes. Additionally, the apparatus can communicate the atlas including the one or more patches. The apparatus can also calculate an amount of user motion associated with the rendered content in the frame. Further, the apparatus can determine a size of each of the one or more bounding boxes based on the calculated amount of user motion. The apparatus can also determine a size and location of each of the one or more patches in the atlas.

Abstract: Systems and techniques are described herein for generating and/or processing virtual content in a distributed system (e.g., a distributed extended reality system). For example, a first device (e.g., a client device) of a distributed extended reality system may transmit one or more sets of pose prediction parameters (e.g., prediction coefficients, prediction time associated with raw pose data, and/or the raw pose data) to a second device (e.g., a server device) of the distributed extended reality system. The second device may predict one or more poses of the second device based on the set(s) of pose prediction parameters, and may generate virtual content based on a pose of the predicted pose(s) of the first device. The second may transmit and the first device may receive the virtual content. The first device may then display one or more virtual objects based at least in part on the received virtual content.

Abstract: Graphics processing in a client device includes receiving, as part of a vector streaming split rendering process, a bit stream encoding a sequence of shading atlases of the process. Each shading atlas includes blocks. The client decodes a particular shading atlas of the sequence of shading atlases, and determines that a particular block of the particular shading atlas was unsuccessfully decoded. The client identifies a stored block of a prior shading atlas of the sequence of shading atlases as a successfully decoded earlier version of the particular block. The client renders the particular shading atlas using the stored block instead of the particular block.
