  26. Antialiasing – Midpoint Line Algorithm Properties of Unweighted Area Sampling: • Intensity of a pixel intersected by a line decreases as the distance between the pixel center and the edge increases. • A primitive (e.g. line) does not influence a pixel at all if they are not intersected. • Equal areas contribute equal intensity, regardless of the distance between the pixel’s center and the area.
