PVS over UDP for split rendering

A method of graphics processing at a first device, comprising:

• obtaining a potentially visible set (PVS) and a set of video packets, wherein the PVS includes PVS information associated with a set of visible primitives that are potentially visible in a first frame, wherein the set of visible primitives corresponds to a set of meshlets, and each meshlet of the set of meshlets includes at least one visible primitive of the set of visible primitives;
• determining, 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, wherein each first visible primitive in the one or more first visible primitives is affected by at least one of a video packet error, a meshlet visibility error, a meshlet atlas information error, or a meshlet level change error;
• identifying 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;
• and
• updating information associated with the one or more first visible primitives based on the concealment information for the one or more first visible primitives.

A non-transitory computer-readable medium storing computer executable code, the code, when executed by at least one processor, causes the at least one processor to:

• obtain a potentially visible set (PVS) and a set of video packets, wherein the PVS includes PVS information associated with a set of visible primitives that are potentially visible in a first frame, wherein the set of visible primitives corresponds to a set of meshlets, and each meshlet of the set of meshlets includes at least one visible primitive of the set of visible primitives;
• 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, wherein each first visible primitive in the one or more first visible primitives is affected by at least one of a video packet error, a meshlet visibility error, a meshlet atlas information error, or a meshlet level change error;
• 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;
• and
• update information associated with the one or more first visible primitives based on the concealment information for the one or more first visible primitives.
