Effektives Anti-Aliasing für die Bilderzeugung auf Rastersichtgeräten

Es wird ein Algorithmus zur Bestimmung der Subpixel—Maske beschrieben, der sich gut fur eine Hardware—Realisierung eignet. Der Algorithmus verlangt nur Additionen, Subtraktionen und Schiebe—Operationen. Es werden die existierenden Ansatze zur Beseitigung von Alias—Effekten und die entsprechenden Implementierungen verglichen sowie die Vorteile des Algorithmus hinsichtlich seiner Anpassungsfahigkeit an das vorgestellte Pipeline—Konzept dargestellt.
