Correction is made for quantization error in texture coordinates introduced by transforming between coordinate systems and in MIP map downsampling. In order to correct for coordinate system transformation, the coordinate value is multiplied by the MIP map size and a first value is subtracted. In order to correct for map downsampling, the coordinate value is, for each map downsampled, divided by a second value and a third value subtracted. The first, second, and third values are dependent upon how the coordinate system and maps are defined. The two corrections are integrated by the present invention into a single operation performed on the texture coordinate values. | |
