  • Patent number: 8610729
    Abstract: A floating point rasterization and frame buffer in a computer system graphics program. The rasterization, fog, lighting, texturing, blending, and antialiasing processes operate on floating point values. In one embodiment, a 16-bit floating point format consisting of one sign bit, ten mantissa bits, and five exponent bits (s10e5), is used to optimize the range and precision afforded by the 16 available bits of information. In other embodiments, the floating point format can be defined in the manner preferred in order to achieve a desired range and precision of the data stored in the frame buffer. The final floating point values corresponding to pixel attributes are stored in a frame buffer and eventually read and drawn for display. The graphics program can operate directly on the data in the frame buffer without losing any of the desired range and precision of the data.

  • Patent number: 8212835
    Abstract: One embodiment of the present invention sets forth a technique for transitioning from bilinear sampling to filter-4 sampling, while avoiding the visual artifacts along the boundary between the two different types of filters. The technique may be implemented using a linear transition function or an arbitrary transition function stored in a lookup table. The transition to filter-4 sampling occurs when the view of a textured object includes both minified and magnified levels of texture detail. Using this technique, high image quality is maintained for texture mapped images that include both highly minified pixels as well as highly magnified pixels, without suffering the performance penalty associated with using a filtering operation such as filter-4 sampling across all pixels.

  • Patent number: 7924290
    Abstract: A method and system for performing a texture operation with user-specified offset positions are disclosed. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of deriving a first destined texel position based on an original sample position associated with a pixel projected in a texture map and a first offset position specified by a user and fetching texel attributes at the first destined texel position for the texture operation.

  • Patent number: 7526125
    Abstract: The present invention provides for a method of and apparatus for compressing and uncompressing image data. According to one embodiment of the present invention, the method of compressing a color cell comprises the steps of: defining at least four luminance levels of the color cell; generating a bitmask for the color cell, the bitmask having a plurality of entries each corresponding to a respective one of the pixels, each of the entries for storing data identifying one of the luminance levels associated with a corresponding one of the pixels; calculating a first average color of pixels associated with a first one of the luminance levels; calculating a second average color of pixels associated with a second one of the luminance levels; and storing the bitmask in association with the first average color and the second average color.
