C omputers have become a powerful tool for the rapid and economical producTIonof pictures. There is virtually no area in which graphical displayscannot be used to some advantage, and so it is not surprising to find the use ofcomputer graphics so widespread. Although early applicaTIons in engineeringand science had to rely on expensive and cumbersome equipment, advances incomputer technology have made interacTIve computer graphics a pracTIcal tool.Today, we find computer graphics used routinely in such diverse areas as science,engineering, medicine, business, industry, government, art, entertainment, advertising,education, and training. Figure 1-1 summarizes the many applicationsof graphics in simulations, education, and graph presentations. Before we getinto the details of how to do computer graphics, we first take a short tourthrough a gallery of graphics applications.
