1. In a graphics hardware environment, a method of blurring an original image, comprising: a) generating at least two copies of at least a portion of the original image; b) transforming at least a first one of the copies a first transformation amount; c) transforming at least a second one of the copies a second transformation amount that is different from the first transformation amount; d) averaging the transformed copies together to generate a blended image; e) changing the first and second transformation amounts by a predetermined factor; and f) repeating steps a) through e) a predetermined number of times using the blended image instead of the original image to thereby generate a blurred image.
