Record-time optimization of display lists

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a display list. Graphics processing commands are identified for generation of one or more graphical images on a computer device. During an initial recording of a graphics display list to include the graphics processing commands, if a sub-list of the display list is determined to not include any drawing commands, the display list is recorded so that commands on the sub-list are not executed when the display list is executed.

主权项

1. A computer-implemented method comprising:
receiving, by one or more computers, graphics processing commands for generation of one or more graphical images on a computer device; as each graphics processing command is received, during a record time when a graphics display list is initially generated, and before any compiling of the graphics display list occurs:
determining whether each graphics processing command is not a drawing command, andinitially recording the graphics display list, by the one or more computers, for later execution so that a sub-list of particular commands that are determined to not be drawing commands are not executed when the display list is executed, by the particular commands being indicated as non-executing or being discarded; and executing the display list for generation of the one or more graphical images.
