ABSTRACT:
Method and apparatus for graphics processing is described. More particularly, a graphics processing subsystem capable of multi-pass graphics data processing is described. The graphics processing subsystem includes a geometry processor and a fragment processor, where output from the fragment processor is input compatible with the geometry processor. Data produced in a pass through a graphics data-processing pipeline including the fragment processor and geometry processor may be used as an input to processing during a subsequent pass. Data read from a texture map may be used to define or modify data, including vertex data, being processed in the geometry processor or the fragment processor.
