Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: For a scene comprising real-world objects and generated (CG) objects, the scene characterized by a scene geometry of a first time, one or more processors can generate, based on the scene geometry, shadow information for each of one or more shadows cast by a CG object of the scene on one or more real-world objects of the scene. The one or more processors can rendering and display a frame of the scene as a function of the shadow information and a scene geometry at a time of the rendering later than the first time. In some examples, the shadow information includes shadow factors and identifiers. Each shadow factor can describe a light attenuation effect of a cast shadow on a real world object surface and can be incorporated into a shading atlas of the scene. Each identifier identifies a real-world object surface of the scene affected by a shadow factor.

Abstract: Methods, systems, and devices for computer graphics are described. A device may perform a shadow rendering operation in an object-space shading pipeline for a set of potentially visible surfaces. The device may represent the potentially visible surfaces in an atlas. The device may determine a set of world-space coordinates corresponding to the one or more potentially visible surfaces and may store the set of world-space coordinates in a geometry buffer (G-buffer). The device may determine a number of shadow factors associated with the potentially visible surfaces based on a transformation of the world-space coordinates stored in the G-buffer and a set of depth values associated with each shadow caster present in a scene. The device may store the shadow factors in an atlas shadow mask and perform a shading of the potentially visible surfaces in the atlas based on the atlas shadow mask.
