Introduction

Computer graphics is a field of computer science, which deals with creation, representation and
management of images on the computer screen. Computer graphics deals with the technological and
theoretical aspects of computerized image synthesis. An image created by a computer can illustrate a
simple scene as well as complex scenes.
A simple scene would be the outline of a triangle on an even background, and a
complex scene would be a stunning dinosaur in a forest.

It can be said that computer graphics is an immense field that includes almost any graphical aspect,
such as generation of images.

Did you know? A Massachusetts Institute of Technology (MIT) student, Ivan Sutherland was the first
to create a computer graphic. Sutherland produced a computer drawing program
called Sketchpad in 1961. With the help of a light pen, the Sketchpad allowed one to
draw simple shapes on the computer screen, save them, and even retrieve them later.
