Line 1: The '''Weiler–Atherton [[Clipping (computer graphics)\|clipping]] [[algorithm]]''' is used in [[computer graphics]]. It allows clipping of a ''subject polygon'' by an arbitrarily shaped ''clip polygon'' window. It is generally applicable only in [[2D computer graphics\|2D]]. However, it can be used in [[3D computer graphics\|3D]] through visible surface determination and with improved efficiency through [[Z-order~~\| Z-ordering~~]]ing. <ref> Foley, James, Andries van Dam, Steven Feiner, and John Hughes.
