Abstract
A method corrects opacity values of samples in a rendering pipeline. The method partitions a range of uncorrected alpha values into a plurality of segments in a low to high order. Corrected alpha values for uncorrected alpha values in the highest segment are determined by direct table look-up. Corrected alpha values for uncorrected alpha values in all but the highest segment are determined by linear interpolation.
