Computer graphics facilitates the
production of images that range in
complexity from simple line drawings
to three-dimensional reconstructions
of data obtained from computerized
axial tomography (CAT) scans in
medical applications. |

•
A branch of computer science that deals with
the theory and techniques of computer image
synthesis. Computers produce images by
analyzing a collection of dots, or pixels
(picture elements). |

 |
•Computer
graphics is used to enhance the transfer and
understanding of information in science,
engineering, medicine, education, and
business by facilitating the generation,
production, and display of synthetic images
of natural objects with realism almost
indistinguishable from photographs. |

User interaction
can be increased through animation,
which conveys large amounts of
information by seemingly bringing to
life multiple related images.
Animation is widely used in
entertainment, education, industry,
flight simulators, scientific
research. |

Virtual-reality
applications permit users to interact
with a three-dimensional world, for
example, by “grabbing” objects and
manipulating objects in the world. |

Digital image
processing is a companion field to
computer graphics. However, image
processing, unlike computer graphics,
generally begins with some image in
image space, |

|
 |
 |
| Computers
are equipped with special hardware to
display images. Several types of image
presentation or output devices convert
digitally represented images into
visually perceptible pictures. They
include pen-and-ink plotters,
dot-matrix plotters, electrostatic or
laser-printer plotters |
