Method and apparatus for texture level of detail dithering |
摘要 |
A computationally efficient method for minimizing the visible effects of texture LOD transitions across a polygon. The minimization is accomplished by adding a dithering offset value to the LOD value computed for each pixel covered by a graphics primitive to produce a dithered pixel LOD value. The dithering offsets mat be generated from a table look-up based on the location of the pixel within a span of pixels. The dithered pixel LOD value is used to as an index in the selection of a single LOD texture map from which a textured pixel value is retrieved. The range of dithering offset values can be adjusted by modulating the values in the table look-up.
