Abstract
Performing primitive composition within a user interface thread, enhancing the ability to scale a user interface framework to computing devices having limited resources. In one or more embodiments, a user interface thread walks a user interface hierarchy that describes elements of a program's user interface and directly generates static Graphics Processing Unit (GPU) data structures representing at least a portion of the user interface hierarchy. The user interface thread passes the static GPU data structures to a composition thread, which uses these static GPU data structures during generation of a plurality of video frames. This includes the composition thread, based on the static GPU data structures, sending GPU data and GPU commands for the plurality of video frames to a GPU for rendering.
