Abstract
At least one of graphics operation description information or graphics object description information (106) is included within application logic (102). At least one of the graphics operation description information or graphics object description information (106) is included in the program address space of a graphics driver (108).
Claims7
A method comprising:
- storing graphics operation description information in a stored location in application logic embodied in machine circuits;
- and
- causing the stored location of the graphics operation description information in the application logic to become part of a program address space of graphics driver logic embodied in the machine circuits;
- the driver logic accessing the stored location and testing effects on a graphics system of graphics operations defined by the graphics operation description information and/or graphics object description information before the graphics operations are invoked by the application logic.
1 more element
A method comprising:
- adapting application logic embodied in machine circuits to create graphics operation description information;
- and
- incorporating the graphics operation description information in a stored location in a loader-compatible version of the application logic embodied in the machine circuits, and making the stored location part of an address space of a graphics device driver;
- the driver logic accessing the stored location and testing effects on a graphics system of graphics operations defined by the graphics operation description information and/or graphics object description information before the graphics operations are invoked by the application logic.
