Method of rendering a user interface

摘要

A user interface (UI) is presented in which a UI client engine is associated with an application, and a UI rendering engine is associated with the client engine. The UI client engine processes a client thread to manage a scene graph. The UI rendering engine receives the scene graph and data items associated with elements of the scene graph, and processes a rendering thread to render a UI in accordance with the scene graph and the data items, independently of further input from the client UI engine.
