TECHNIQUES FOR LOCALLY MODIFYING DRAW CALLS

摘要

One embodiment sets forth a method for modifying draw calls using a draw-call shader program included in a processing subsystem configured to process draw calls. The draw call shader receives a draw call from a software application, evaluates graphics state information included in the draw call, generates modified graphics state information, and generates a modified draw call that includes the modified graphics state information. Subsequently, the draw-call shader causes the modified draw call to be executed within a graphics processing pipeline. By performing the computations associated with generating the modified draw call on-the-fly within the processing subsystem, the draw-call shader decreases the amount of system memory required to render graphics while increasing the overall processing efficiency of the graphics processing pipeline.
