ABSTRACT:
Intermediate target(s) are utilized in connection with computer graphics in a computer system. In various embodiments, intermediate memory buffers in video memory are utilized to allow serialized programs from graphics APIs to support algorithms that exceed the instruction limits of procedural shaders for single programs. The intermediate buffers may also allow sharing of data between programs for other purposes as well, and are atomically accessible. The size of the buffers, i.e., the amount of data stored in the intermediate targets, can be variably set for a varying amount of resolution with respect to the graphics data. In this regard, a single program generates intermediate data, which can then be used, and re-used, by an extension of the same program and/or any number of other programs any number of times, enabling considerable flexibility and complexity of shading programs, while maintaining the speed of modern graphics chips.
