A generalization of the z-buffer algorithm is given that allows for dynamic updates of a screen image without the necessity of re-drawing the entire scene. It is based on the notion of equivalent classes of pixels, that is groups of pixels that are covered by the same set of polygons. A data structure for representing these equivalence classes in an efficient manner is discussed.
