ABSTRACT
Computer graphics is everywhere: on the web, in our homes (high-end appliances, computers, game consoles
and television — weather, news and broadcast sports), in our cars (GPS systems), in the movies and arcades
and on our persons (PDAs, mobile phones and wearable computers). The term computer graphics refers to
the generation, representation, manipulation, processing and visual display of data using a computer.
Computer-generated images may be two-dimensional (2D) or three-dimensional (3D); they may be animated
or still, and portray real scenes, imagined scenes, or things not normally visible such as forces. Image
processing is closely related to computer graphics but omits the initial generation phase and starts instead with
an image captured by some other device.
