More Information
Summary: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.
