摘要： A system, method and computer program product are provided for branching during programmable processing utilizing a graphics application program interface in conjunction with a hardware graphics pipeline. Initially, a first instruction defined by the graphics application program interface is identified. A first operation is performed on graphics data based on the first instruction utilizing the hardware graphics pipeline. Any some point, the present technique may involve branching to an additional instruction defined by the graphics application program interface other than a subsequent sequential instruction. Next, another operation is performed on the graphics data based on the additional instruction utilizing the hardware graphics pipeline.

Initially, a vertex program is identified including branch labels and instruction sequences with branch commands. The vertex program is then converted to a binary format capable of being executed by a hardware graphics pipeline. The vertex program may then be executed in the binary format utilizing the hardware graphics pipeline for transforming vertices. As an option, the vertex program is initially written in a textual format capable of being read by a human prior to being converted.

摘要： One embodiment of the present invention sets forth a technique for improving path rendering on computer systems by efficiently representing and computing sub-pixel coverage for path objects. A stencil buffer is configured to store multiple stencil samples per pixel stored in an image buffer. The stencil samples undergo stencil testing to produce a set of Boolean values per pixel, which collectively define a geometric coverage percentage for the pixel. The coverage percentage is used to modulate a color value for the pixel. The modulated color value is then blended into the image buffer as an anti-aliased pixel. This technique advantageously enables efficient anti-aliasing for path rendering.

摘要： One embodiment of the present invention sets forth a technique for performing a computer-implemented method for tessellating patches. An input block is received that defines a plurality of input patch attributes for each patch as well as instructions for processing each input patch. A plurality of threads is launched to execute the instructions to generate each vertex of a corresponding output patch based on the input patch. Reads of values written during instruction execution are synchronized so threads can read and further process the values of other threads. An output patch is then assembled from the outputs of each of the threads; and emitting the output patch for further processing.

摘要： A system, method and computer program product are provided for programmable processing of fragment data in a computer hardware graphics pipeline. Initially, fragment data is received in a hardware graphics pipeline. It is then determined whether the hardware graphics pipeline is operating in a programmable mode. If it is determined that the hardware graphics pipeline is operating in the programmable mode, programmable operations are performed on the fragment data in order to generate output. The programmable operations are performed in a manner/sequence specified in a graphics application program interface. If it is determined that the hardware graphics pipeline is not operating in the programmable mode, standard graphics application program interface (API) operations are performed on the fragment data in order to generate output.

摘要： Methods and systems for processing a geometry shader program developed in a high-level shading language are disclosed. Specifically, in one embodiment, after having received the geometry shader program configured to be executed by a first processing unit in a programmable execution environment, the high-level shading language instructions of the geometry shader program is converted into low-level programming language instructions. The low-level programming language instructions are then linked with the low-level programming language instructions of a domain-specific shader program, which is configured to be executed by a second processing unit also residing in the programmable execution environment. The linked instructions of the geometry shader program are directed to the first processing unit, and the linked instructions of the domain-specific shader program are directed to the second processing unit.

摘要： One embodiment of the invention sets forth a method for storing graphics data in a texture array in a local memory coupled to a graphics processing unit. The method includes the steps of specifying the texture array as a target in the local memory, and loading a first block of texture maps into the texture array, wherein each texture map in the first block has a first resolution and corresponds to a different slice of the texture array. One advantage of the disclosed method is that a complete block of texture images may be loaded into a texture array using a single API call. Thus, compared to prior art systems, where a texture array must be loaded one image for one slice of the array at a time, the disclosed method increases the efficiency of using arrays of texture maps for graphics processing operations.
