GKS and Object-Oriented System Design

Abstract

In this chapter we will be looking at the graphics standard GKS through the object-oriented lens. Several differences between a traditional graphics kernel system as GKS and an object-oriented graphics system will be described. Simultaneously, we will introduce the goals of standardizing a graphics system. Some of the examples encompass an object-oriented modification of GKS, to aid in pointing out the differences between the traditional and object-oriented approaches. By no means do we propose a modified GKS as the graphics system of the future. It should be noted that much of what is said on the next few pages also applies to the standard PHIGS. But PHIGS will be analyzed in more detail in other chapters of the book.
