Abstract: Particular embodiments of a computing device may provide a main thread, a graphics thread to handle tasks related to rendering and presenting a graphical user interface (GUI), and an input thread to handle tasks related to processing input-related events. The GUI may comprise at least one animated component associated with a set of state variables. The main thread may handle tasks to generate a GUI hierarchy and provide copies of the GUI hierarchy to the input thread and the graphics thread. The input thread may handle tasks to initialize and update the state variables and provide information about the state variables to the graphics thread. The graphics thread may then handle tasks to update the GUI by rendering a first frame of the animation based on the state variables.

Abstract: In one embodiment, a first thread of execution on a computing device receives a user-interface input. The first thread of execution is associated with a user interface of the computing device. The first thread of execution identifies a second thread of execution on the computing device to process the user-interface input. The second thread of execution is associated with the user interface and is de-coupled from the first thread of execution. The first thread of execution sends the user-interface input to the second thread of execution. The second thread of execution also processes the user-interface input to generate a user-interface output associated with the user-interface input.

Abstract: In one embodiment, a computing device renders as a first frame of a video a graphical user interface (GUI) of a software application on the computing device based on a multi-layered-tree representation of the GUI. The computing device modifies the multi-layered-tree representation of the GUI in response to an input or output associated with the GUI. The computing device also renders as a second frame of the video of the GUI based on the multi-layered-tree representation of the GUI as modified.

Abstract: Particular embodiments of a computing device include a main thread, a graphics thread, and an input thread. The main thread may execute instructions to generate an object representation of a GUI for an application. Copies of the object representation may be provided to the graphics thread and the input thread. The main thread may determine which displayable sections to render based on user input information, a current location with respect to the GUI, and a caching pattern. The caching pattern may include a first section and one or more second sections adjacent to the first section in one or more directions. The main thread may render the those displayable sections and cache some of the sections. The graphics thread may then asynchronously execute instructions to draw one of the rendered sections into a frame buffer.

Abstract: Particular embodiments provide for asynchronous execution of instructions using a multi-threaded approach to outsource low-level input/output-handling tasks. Particular embodiments may use (1) a main thread to handle execution of instructions to generate a hierarchy of layers representing a GUI, wherein each layer represents a logical grouping of components of the GUI, (2) an input thread to handle asynchronous execution of instructions to process user input based on interactions with the GUI, and (3) a graphics thread to handle asynchronous execution of instructions to generate and/or update display output in relation to one or more layers of the GUI hierarchy. The input thread may send information about received input directly to the graphics thread and the main thread at the same time, thereby enabling the graphics thread to begin refreshing the display output while the main thread performs any necessary processing of the user input.
