  • Patent number: 11917011
    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.
