This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PVS over UDP for split rendering. A graphics processor may obtain, a PVS and a set of video packets. The graphics processor may determine, if a data loss associated with the PVS or the set of video packets is detected, one or more first visible primitives in the set of visible primitives that are currently affected by the data loss associated with the PVS or the set of video packets. The graphics processor may identify concealment information for the one or more first visible primitives in the set of visible primitives based on the one or more first visible primitives in a previous frame. The graphics processor may update information associated with the one or more first visible primitives based on the concealment information for the one or more first visible primitives.

PVS over UDP for split rendering

A client device of a split rendering graphics processing architecture, receives an encoded shading atlas for a current frame. The encoded shading atlas is characterized by slices. The client decodes the received encoded shading atlas and identifies unsuccessfully decoded slices. The client then determines whether each patch of the decoded shading atlas intersects an identified unsuccessfully decoded slice. The client determines, for each intersecting patch, whether a prior valid version of each intersecting patch is stored at the client device. The client error conceals each intersecting patch having a prior valid version stored at the client device with the corresponding prior valid version to create an error concealed atlas. The client renders the current frame using the error concealed atlas.

Error concealment in split rendering using shading atlases

The present disclosure relates to methods and apparatus for graphics processing. Aspects of the present disclosure may identify a first content group and a second content group in a scene. Further, aspects of the present disclosure may determine whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. Additionally, the present disclosure may represent the first content group and the second content group based on the determination whether at least a portion of the first content group occludes or potentially occludes at least a portion of the second content group. In some aspects, the first content group may include at least some real content and the second content group includes at least some augmented content. The present disclosure may also render at least a portion of surfaces of the first content group using an occlusion material.
