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,
then
