AN OVERVIEW OF RENDERING TECHNIQUES

The purpose of this paper is to present a basic introduction to computer graphics rendering techniques-techniques for the generation of realistic visual images. The paper has four major sections, reflecting the major areas of rendering: visible surface identification; anti-aliasing; lighting, shading and shadows; and texture. The development of rendering techniques is an active research area, particularly with respect to lighting models and texture. Some of the techniques presented in this paper will be superseded within a very short time. Nonetheless, this should still serve as a base from which researchers, practitioners, and students can explore those new developments. © 1990.
