Abstract: A method and system for anti-aliased rasterization of objects. From a particular viewpoint of an object represented by shapes, a shape is selected having an edge on a silhouette of the object. An edge geometry is created at the edge of the shape that is on the silhouette of the object. The edge geometry is rendered. Either the shape is rendered after the edge geometry is rendered with the depth test set so as to not allow portions of the shape to overlap the edge geometry, or the shape itself is modified to remove any portion that overlaps the edge geometry. This may be repeated for each edge of each shape that lies on the silhouette of the object.
