Abstract
This paper describes a new perspective on a fundamental algorithm of threedimensional computer graphics namely zbuering An imple mentation of the zbuer method in a lazy functional language behaves in a quite dierent manner to the traditional imperative counterpart The main result of this paper is to show that the lazy zbuer is a scanline method The eective dierence between scanline methods and zbuers is one of order of evaluation A hybrid algorithm with properties common to both zbuer and scanline methods is also described In section we describe the implementation of a simple zbuer algorithm in a functional language We then section examine its behaviour under eager and lazy evaluation schemes In this section we brie y describe some of
