ABSTRACT:
A method and system for controlling the algorithmic elements in 3D graphics systems via an improved 3D graphics API is provided. In one aspect, in a 3D graphics system having privatized formats with privatized drivers used to increase the efficiency of display, existing problems are eliminated that are associated with multiple redundant copies of the publicly formatted graphics data made in host system memory pursuant to various graphics operations e.g., lock and unlock operations. The ability to make a system copy of publicly formatted data is exposed to the developer, eliminating the creation of unnecessary, and redundant copies. Efficient switching between the privatized and public format remains hidden from the developers so that applications execute efficiently while removing consideration thereof from the developers. Thus, developers are free to consider other tasks. In the event that a developer wishes to make a copy of the data, the data is copied pursuant to an operation that the developer calls and over which the developer has control, ensuring that multiple redundant copies of the graphics data are not made in host system memory.
