    摘要： Digital Image compositing using a programmable graphics processor is described. The programmable graphics processor supports high-precision data formats and can be programmed to complete a plurality of compositing operations in a single pass through a fragment processing pipeline within the programmable graphics processor. Source images for one or more compositing operations are stored in graphics memory, and a resulting composited image is output or stored in graphics memory. More-complex compositing operations, such as blur, warping, morphing, and the like, can be completed in multiple passes through the fragment processing pipeline. A composited image produced during a pass through the fragment processing pipeline is stored in graphics memory and is available as a source image for a subsequent pass.

    摘要： A graphics processor and method for executing a graphics program as a plurality of threads where each sample to be processed by the program is assigned to a thread. Although threads share processing resources within the programmable graphics processor, the execution of each thread can proceed independent of any other threads. For example, instructions in a second thread are scheduled for execution while execution of instructions in a first thread are stalled waiting for source data. Consequently, a first received sample (assigned to the first thread) may be processed after a second received sample (assigned to the second thread). A benefit of independently executing each thread is improved performance because a stalled thread does not prevent the execution of other threads.

    摘要： A system, method and computer program product are provided for texture shading in a hardware graphics processor. Initially, a plurality of texture coordinates is identified. Further, it is determined whether a hardware graphics processor is operating in a texture shader mode. If the hardware graphics processor is operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a plurality of texture shader stages in the hardware graphics processor. If, however, the hardware graphics processor is not operating in the texture shader mode, the texture coordinates are mapped to colors utilizing a conventional graphics application program interface (API) in conjunction with the hardware graphics processor.
