Abstract
A method and an apparatus reduces aliasing artifacts in images defined by pixels. A pixel is partitioned into subpixel locations from which sample points are selected. A fragment of the image is determined to be visible at at least one of the sample points. A fragment value associated with that fragment is stored. Each sample point at which the fragment is visible is linked to the stored fragment value. A color of the pixel is computed from the stored fragment values to reduce the aliasing artifacts in the image.
