One aspect of the invention is a method for accelerating noise. The method
includes the step of creating a plurality noise texture values (n.sub.1, .
. . , n.sub.n) each corresponding to one of a plurality of image pixel
values (x.sub.1, . . . , x.sub.n). The method also includes invoking at
least a portion of a graphics pipeline (17) to blend each of the plurality
of image pixel values (x.sub.1, . . . , x.sub.n) with one of the plurality
of noise texture values (n.sub.1, . . . , n.sub.n).
