Abstract:
A computerized method for determining a color of a pixel of an image, the pixel being associated with a set of subpixel samples, the set of subpixel samples having a plurality of subpixel samples, the set of subpixel samples having a number of subpixel samples, comprising:storing a plurality of distinct fragment values for the pixel up to a predetermined maximum number of distinct fragment values, each stored fragment value being associated with at least one subpixel sample, each stored fragment value being associated with a fragment that is visible in the pixel, the predetermined maximum number of fragment values being less than the number of subpixel samples;determining that a new fragment is visible in the pixel with at least one other fragment with a stored fragment value still being visible in the pixel, the new fragment having a new fragment value;selecting one of the visible stored fragment values; andreplacing the selected fragment value with the new fragment value wherein the stored fragment values are subsequently used to generate the color of the pixel.
