Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for multi-layer reprojection techniques for augmented reality. A display processor may obtain a layer of graphics data including a plurality of virtual objects. Each the plurality of virtual objects may be associated with at least one bounding box of a plurality of bounding boxes. The display processor may further obtain metadata indicative of at least one edge of the at least one bounding box of the plurality of bounding boxes, and metadata corresponding to reprojection instructions associated with each of the plurality of bounding boxes. The display processor may reproject the plurality of virtual objects based on the metadata indicative of the at least one edge of the at least one bounding box and the metadata corresponding to the reprojection instructions.

Abstract: Techniques and systems are provided for light estimation. In some examples, a system receives a plurality of frames associated with a scene. The plurality of frames includes a first frame and a second frame occurring after the first frame. The system determines, based on image data of the first frame, a first light estimate associated with the scene. The system also determines, based on image data of the second frame, a second light estimate associated with the scene. The system further generates an aggregate light estimate associated with the scene based on combining the second light estimate with at least the first light estimate.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine an eye-buffer including one or more bounding boxes associated with rendered content in a frame. The apparatus can also generate an atlas based on the eye-buffer, the atlas including one or more patches associated with the one or more bounding boxes. Additionally, the apparatus can communicate the atlas including the one or more patches. The apparatus can also calculate an amount of user motion associated with the rendered content in the frame. Further, the apparatus can determine a size of each of the one or more bounding boxes based on the calculated amount of user motion. The apparatus can also determine a size and location of each of the one or more patches in the atlas.
