Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus may identify at least one mesh associated with at least one frame. The apparatus may also divide the at least one mesh into a plurality of groups of primitives, each of the plurality of groups of primitives including at least one primitive and a plurality of vertices. The apparatus may also compress the plurality of groups of primitives into a plurality of groups of compressed primitives, the plurality of groups of compressed primitives being associated with random access. Additionally, the apparatus may decompress the plurality of groups of compressed primitives, at least one first group of the plurality of groups of compressed primitives being decompressed in parallel with at least one second group of the plurality of groups of compressed primitives.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus may configure a plurality of billboards associated with a viewpoint of a first frame of a plurality of frames, the plurality of billboards being configured in one or more layers at least partially around the viewpoint, the configuration of the plurality of billboards being based on one or more volumetric elements between at least one of the plurality of billboards and the viewpoint. The apparatus may also render an image associated with each of the one or more volumetric elements between at least one billboard of the plurality of billboards and the viewpoint, the rendered image including a set of pixels. The apparatus may also store data in the at least one billboard based on the rendered image associated with each of the one or more volumetric elements, the data corresponding to the set of pixels.

Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may divide at least one scene into a plurality of meshlets, each of the meshlets including a plurality of primitives, and each of the primitives including plurality of vertices. The apparatus may also calculate a pair of texture coordinates for each of the plurality of vertices. Further, the apparatus may select a size of each of the plurality of meshlets in the at least one scene based on the pair of the texture coordinates and based on a perspective projection of each of the plurality of meshlets. The apparatus may also calculate layout information in a meshlet atlas for each of the meshlets in the at least one scene. Moreover, the apparatus may shade each of a plurality of pixels in the meshlet atlas based on the calculated layout information.

Abstract: The present disclosure relates to methods and apparatus for graphics processing at a server and/or a client device. In some aspects, the apparatus may convert application data for at least one frame, the application data corresponding to one or more image functions or one or more data channels. The apparatus may also encode the application data for the at least one frame, the application data being associated with a data stream, the application data being encoded via a video encoding process. The apparatus may also transmit the encoded application data for the at least one frame. Additionally, the apparatus may receive application data for at least one frame, the application data being associated with a data stream. The apparatus may also decode the application data for the at least one frame; and convert the application data for the at least one frame.
