    摘要: The boundary of a surface can be represented as a series of line segments. A number of polygons are successively superimposed onto the surface. The polygons utilize a common reference point and each of the polygons has an edge that coincides with one of the line segments. Coverage bits are associated with respective sample locations within a pixel. A value of a coverage bit is changed each time a sample location associated with the coverage bit is covered by one of the polygons. Final values of the coverage bits are buffered after all of the polygons have been processed. The values of the coverage bits can be used when the surface is subsequently rendered.

    摘要: In a raster unit of a graphics processor, a method for bounding region accumulation for graphics rendering. The method includes receiving a plurality of graphics primitives for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitives to generate a plurality pixels related to the graphics primitives and a plurality of respective bounding regions related to the graphics primitives. Upon receiving an accumulation start command, the bounding regions are accumulated in an accumulation register. The accumulation continues until an accumulation stop command is received. The operation results in an accumulated bounding region. Access to the accumulated bounding region is enabled to facilitate a subsequent graphics rendering operation.

    摘要: Methods and systems for decompressing data are described. The relative magnitudes of a first value and a second value are compared. The first value and the second value represent respective endpoints of a range of values. The first value and the second value each have N bits of precision. Either the first or second value is selected, based on the result of the comparison. The selected value is scaled to produce a third value having N+1 bits of precision. A specified bit value is appended as the least significant bit of the other (non-selected) value to produce a fourth value having N+1 bits of precision.

    摘要: Data that includes an encoded version of sets of color component values for a block of texels is accessed. The encoded version includes a first set of color component values selected from a pre-encoded version of the sets and a second set of color component values selected from the pre-encoded version of the sets. The first set and the second set correspond to endpoints of a range of colors. The encoded version further includes index values associated with the texels. The first set and the second set and an index value associated with a texel are used to decode a third set of color component values that describes a color for the texel. The index value indicates how to determine the third set using the first set and the second set.
