The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing. The term Computer graphics has more meaning:
the representation and manipulation of pictorial data by a computer
the various technologies used to create and manipulate such pictorial data
the images so produced, and
a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content.
Today much of our life is affected by computers, and by computer graphics. Whether you see them on television, in newspapers, in weather reports or while at the doctor's surgery, computer images are all around you. A well-chosen graph is able to transform a complex table of numbers into meaningful results. Such graphs are used to illustrate papers, reports, and theses, as well as providing the basis for presentation material in the form of slides and overhead transparencies. A range of tools and facilities are available to enable users to visualise their data, and computer graphics are used in many disciplines.
