Abstract: A method by a rendering device includes receiving a request to render multiple surfaces corresponding to multiple virtual objects to be concurrently displayed on an augmented-reality (AR) headset. The method further includes that the AR headset is connected to the rendering device via a wireless link. In response to a determination that a network quality of the wireless link is below a threshold condition, the method further includes selecting a first subset of the multiple surfaces that are higher priority than a second subset of the plurality of surfaces. The method includes transmitting the first subset of multiple surfaces to the AR headset for display and transmitting the second subset of multiple surfaces to the AR headset for display after transmitting the first subset. This method includes rendering the surfaces in accordance with a set of rendering parameters so as to satisfy one or more network constraints.

The method further includes that the AR headset is connected to the rendering device via a wireless link. In response to a determination that a network quality of the wireless link is below a threshold condition, the method further includes selecting a first subset of the multiple surfaces that are higher priority than a second subset of the plurality of surfaces. The method includes transmitting the fist subset of multiple surfaces to the AR headset for display and transmitting the second subset of multiple surfaces to the AR headset for display after transmitting the first subset. This method includes rendering the surfaces in accordance with a set of rendering parameters so as to satisfy one or more network constraints.

Abstract: In one embodiment, a method includes accessing, from a client system associated with a first user, multiple surfaces in an artificial reality scene, wherein the multiple surfaces are projected for display to the first user based on an eye pose of the first user; capturing a frame of the real-world environment while displaying the artificial reality scene to the first user, wherein the captured frame of the real-world environment is associated with a camera pose; reprojecting the multiple surfaces based on the camera pose; generating an aligned artificial reality scene based on the reprojected multiple surfaces and the captured frame of the real-world environment; and sending the aligned artificial reality scene to a second user for display.
