Abstract: An antialiasing method, comprising:
providing a first fragment;
computing a first coverage area representing a portion of the first fragment covered by a first primitive;
providing a second fragment juxtaposed to the first fragment and at least partially covered by a second primitive;
processing the first coverage area to obtain a corrected coverage area indicative of a visible first fragment portion resulting from the juxtaposition of said fragments;
applying an antialiasing procedure based on said corrected coverage area.
