Computer graphics are very useful. 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.

Computer-generated imagery is used for movie making, video game and computer program development, scientific modeling, and design for catalogs and other commercial art. Some people even make computer graphics as art. We can classify applications of computer graphics into four main areas:

• Display of information
• Design
• User interfaces
• Simulation

According to these four areas there are several types of applications which are used in today’s world.
