摘要： 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.
摘要翻译：本发明的一个实施例提出了一种用于从双线性采样转换到滤波器4采样的技术，同时避免沿着两种不同类型的滤波器之间的边界的视觉伪影。该技术可以使用存储在查找表中的线性过渡函数或任意过渡函数来实现。当纹理对象的视图包括纹理细节的缩小和放大级别时，会发生到过滤器4采样的转换。使用这种技术，对于包括高度缩小的像素以及高度放大的像素的纹理映射图像，保持高图像质量，而不会遭受与使用诸如所有像素之间的滤波器4采样的滤波操作相关联的性能损失。

摘要： 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.

摘要： 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. In one embodiment, the color cell includes a matrix of 4×4 pixels, the bitmask includes 32-bits and each of the color values includes 16-bits such that a compression rate of 4-bits per pixel is achieved. The present invention is particularly applicable to compress texture data such that the texture data can be more efficiently cached and moved during texture mapping. In that embodiment, the present invention can also support the compression of luminance, intensity and alpha textures.

摘要： A method and apparatus for efficiently managing texture memory in computer graphics systems is provided. Texture images are stored in discrete memory-aligned tiles to avoid fragmentation in the texture memory. Larger texture images are divided up into smaller tiles so that they will fit in any available tile region in texture memory. Small texture images usually fit into a single tile and therefore do not usually have to be divided up. Texture images that are larger than a tile region are split up into tile-sized images that are stored individually in any available tile region of texture memory. By dividing up the larger texture images this way, the texture memory is used more efficiently because any gaps that appear in the texture memory due to fragmentation may be filled by the tile-sized images.
