Abstract
In this paper we present an approach for teaching visibility computati on algorithms. Its suitability for undergraduate and graduate courses is discussed. The approach is based on the abstraction, during the fir st stages of the teaching process, of the order of the surfaces (plane s, quadrics etc.) of the scene as well as of the model (Brep, CSG etc. ). Specific algorithmic aspects may also be treated at an abstract lev el at first stages. We develop two examples: scan-line and ray-casting . Copyright (C) 1996 Elsevier Science Ltd
