Abstract

All the types of graphics discussed in this book are related in one way or another to functions. Various types of functions are used to parametrize curves and surfaces and to control the red, green, and blue components of colors in many pictures. This is why it is important and convenient to have a separate chapter describing the most common methods of defining functions. Much of this book is designed in such a way that it can be understood with a limited knowledge of functions. In several instances, however, some familiarity with functions defined via procedures is indispensable. For example, in this chapter we describe spline interpolation, which provides an important tool for graphics, and we show how to use iteration of functions to plot some fractal sets.
