abstract = "The Z-buffer shadow algorithm is a popular method for
producing hard shadows. However, antialiasing of the
shadow edges is necessary. This paper provides a new
technique for antialiasing of shadow edges that is
based on the A-buffer hidden-surface algorithm, which
uses bitmasks to describe the area of a pixel occupied
by an object. Compared to percentage-closer filtering,
which is the standard method for antialiasing shadow
edges, the new technique is much faster and has no
noisiness present in the blurred regions.",
