Computer Graphics
The term ‘graphics’ includes almost everything on computers that is not text or sound. Today nearly every computer can do a bit of graphics, and people have come to expect to control their computer through icons and pictures rather than typing.
If you go to a computer and you look really, really carefully you will see tiny, tiny spots which are called pixels. Some people think of computer graphics as drawing pictures on computers, also called rendering. The pictures can be photographs, drawings, movies, or simulations – pictures of things which do not yet exist and maybe could never exist. Or they may be pictures from places we cannot see directly, such as medical images from inside your body.
