  • Patent number: 10229529
    Abstract: A system, method, and computer program product are provided for implementing anti-aliasing operations using a programmable sample pattern table. The method includes the steps of receiving an instruction that causes one or more values to be stored in one or more corresponding entries of the programmable sample pattern table and performing an anti-aliasing operation based on at least one value stored in the programmable sample pattern table. At least one value is selected from the programmable sample pattern table based on, at least in part, a location of one or more corresponding pixels.

  • Patent number: 9978171
    Abstract: A method, system, and computer program product for controlling a sample mask from a fragment shader are disclosed. The method includes the steps of generating a fragment for each pixel that is covered, at least in part, by a primitive and determining coverage information for each fragment corresponding to the primitive. Then, for each fragment, the method includes the steps of generating a sample mask by a fragment shader, replacing the coverage information for the fragment with the sample mask, and writing, based on the sample mask, a result generated by the fragment shader to a memory. The method may be implemented on a parallel processing unit configured to implement, at least in part, a graphics processing pipeline.

  • Patent number: 9454843
    Abstract: A system, method, and computer program product are provided for anti-aliasing. During a first processing pass of a plurality of graphics primitives, z data is computed for multiple samples of each pixel in an image to generate a multi-sample z buffer. During a second processing pass of the graphics primitives, computed color values corresponding to each pixel in a color buffer that stores one color value for each pixel are accumulated.

  • Patent number: 9286659
    Abstract: A system, method, and computer program product are provided for multi-sample processing. The multi-sample pixel data is received and is analyzed to identify subsets of samples of a multi-sample pixel that have equal data, such that data for one sample in a subset represents multi-sample pixel data for all samples in the subset. An encoding state is generated that indicates which samples of the multi-sample pixel are included in each one of the subsets.

  • Patent number: 9262797
    Abstract: A system, method, and computer program product are provided for multi-sample processing. The multi-sample pixel data is received and an encoding state associated with the multi-sample pixel data is determined. Data for one sample of a multi-sample pixel and the encoding state are provided to a processing unit. The one sample of the multi-sample pixel is processed by the processing unit to generate processed data for the one sample that represents processed multi-sample pixel data for all samples of the multi-sample pixel or two or more samples of the multi-sample pixel.

  • Patent number: 9230362
    Abstract: A system, method, and computer program product enable compression with programmable sample locations, where the compression is a function of the programmable sample locations. The method includes the steps of storing a first value specifying a programmed sample location within a pixel in a sample pattern table and storing, in a memory, geometric surface parameters corresponding to a first attribute at the programmed sample location within a first pixel of a display surface. An instruction to store a second value specifying the programmed sample location within the pixel in the sample pattern table is received. The attribute is reconstructed based on the geometric surface parameters and the first value.

  • Patent number: 9142040
    Abstract: A system, method, and computer program product are provided for processing graphics data associated with shading. In operation, a first fragment is received. Further, the first fragment is shaded. While the first fragment is being shaded, a second fragment is received and it is determined whether at least one aspect of the second fragment conflicts with the first fragment. If it is determined that the at least one aspect of the second fragment does not conflict with the first fragment, the second fragment is shaded. If it is determined that the at least one aspect of the second fragment conflicts with the first fragment, information associated with the second fragment is stored, a third fragment is received, and the third fragment is shaded, if it is determined that at least one aspect of the third fragment does not conflict with the first fragment.
