Overview
The term computer graphics includes almost everything on computers that is not text or sound. Today nearly all computers use some graphics and users expect to control their computer through icons and pictures rather than just by typing.[1] The term Computer Graphics has several meanings:
- 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
- the sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content.
Today computers and computer-generated images touch many aspects of our daily life. Computer imagery is found on television, in newspapers, in weather reports, and during surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret. Such graphs are used to illustrate papers, reports, theses, and other presentation material. A range of tools and facilities are available to enable users to visualize their data, and computer graphics are used in many disciplines.
