　　Chapter 2

　　Overview of Graphics Systems

　　Exercise questions for this chapter investigate the characteristics and applications of computergraphics

　　hardware components, the general computer-graphics software concepts, and features

　　of the OpenGL libraries.

　　Exercises

　　2-1. Operating characteristics for display technologies are discussed in Sections 2-1 through

　　2-3 and in the references cited at the end of the chapter.

　　2-2. Applications appropriate for the various display technologies are discussed in Sections 2-1

　　through 2-3 and in the listed references.

　　2-3. A system manual can be consulted to obtain screen dimensions and the number of pixel

　　positions that can be displayed in the x and y directions. If x and y screen dimensions

　　are not listed, they can be measured. The ratio of pixel positions to screen dimensions

　　gives the resolutions for the horizontal and vertical directions. Aspect ratio is the ratio

　　of the y and x resolutions.

　　Alternatively, resolution can be determined by displaying equal-pixel, straight-line segments

　　in the x and y directions and measuring the length of each line.

　　For example, if 100-pixel lines in the x and y directions measure 4 cm and 5 cm, respectively,
