    Abstract: Techniques are disclosed relating to improving the reliable of a computing network. A first computing device receives changing states of a data object to send to a second computing device via a network interface. The first computing device sends, to the second computing device, a baseline packet having a complete one of the states of the data object. The first computing device sends, to the second computing device, a sequence of update packets corresponding to the changing states of the data object. An update packet in the sequence includes sufficient information to update a stored state of the data object at the second computing device to a current state of the data object responsive to the stored state being one of two or more previous ones of the states.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that provide authority transfer of a virtual object in a shared CGR environment. In some implementations, at a first electronic device associated with a first owner having authority to transmit state updates of a virtual object, a state update is transmitted to one or more peers participating in the shared CGR environment associated with the current state of the virtual object by the first electronic device. In some implementations, a handoff message is transmitted to indicate that ownership of the virtual object is being handed off. Then, an acquisition message transmitted by a second electronic device associated with a second owner indicates ownership acquisition of the virtual object by the second owner. The first electronic device accepts state updates of the virtual object transmitted from the second owner based on receiving the acquisition message.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that render perspective correct 2D graphics (e.g., virtual objects, text, graphics) correctly at any angle and distance in an electronic device such as an HMD. In some implementations, a vector graphic including portions defined on a 2D canvas is obtained and the 2D canvas is divided into separate regions, each region containing a plurality of pixels. In some implementations, data based on associating a plurality of the regions of the 2D canvas with the portions of the vector graphic is generated, the data identifying one or more contributing portions of the portions of the vector graphic to use in rendering the pixels in each of the plurality of regions of the 2D canvas. In some implementations, the data is provided to a processor for rendering the vector graphic.
