摘要： A programming interface is provided in a computer graphics system which allows plural hardware display adapters to be upgraded and enhanced without correspondingly upgrading and rewriting display specific device driver code for each separate program application using the graphics system. A resource library with a standard programming interface, but specific to each display adapter is included, as well as display driver code for each adapter. Functions necessary to service the graphics model embodied in the program application are configured as device driver models and also are included within the interface of the present invention. Initially, the functions provided in the resource library are dynamically bound to expose the functionality of the desired display adapter. A second level of dynamic binding is implemented to bind the program application with the display specific code and graphic models being utilized. In this manner, numerous combinations of program applications and display adapters can be used without providing an interface for each possible combination.
