ABSTRACT:
A graphics rendering system creates an image based on objects constructed of polygonal primitives. Aliasing effects in the image are reduced by applying an anti-aliasing scheme to the areas of the image representing silhouette edges of the objects. The silhouette edges are anti-aliased by creating anti-aliasing primitives which vary in opacity. These anti-aliasing primitives are joined to the silhouetted edges, and create a region in the image where the objects appear to blend into the background.
