Computer Graphics includes almost everything on computers that is not text
or sound.
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. We think of computer graphics as drawing pictures on computers, also called rendering.
Computer graphics is an art of drawing pictures, lines, charts, etc using computers with the help of programming. Computer graphics is made up of number of pixels.
There are two types of Computer Graphics
Interactive Computer Graphics
Non Interactive Computer Graphics
Interactive CG involves two way communication between Computer and the user
It can be convinient to input graphical information from the user to computer and have an appropriate graphical output from the computer to the user
Pictures,Charts,Diagrams
Non Interactive CG defines the user has no control over the picture being presented
In non interactive computer graphics otherwise known as passive computer graphics. it is the computer graphics in which user does not have any kind of control over the image.
Example: screen savers.
Creation of an Object with data from one or more of the following
Input coordinates and calculated values
Scanning from an existing drawing
Manipulation
Computer Aided Design
Presentation Graphics
Computer Art
Entertainment
Education and Training
Visualization
Graphical User Interface
It refers to the use of computer graphics to design buildings , automobiles ,aircraft, watercraft , Space Craft and other products
CAD Applications allow the designer to work in a multi window environment i.e., different views of the objects can be displayed in multiple windows
Architects find graphics methods useful to draw floor plans showing the position of rooms ,doors ,stairs etc
Graphics for Engineering and Architectural System
Design of Building, Automobile, Aircraft, Machine etc.

Computer Graphics is used in both fine and commercial art applications
Artists use special purpose hardware and many computer methods such as artists paintbrush programs like Lumena ,Pixel Paint and super paint packages
In Commercial art designing ,photo realistic techniques are generally used .The graphics method commonly used in TV Commercials is called morphing where one object is transformed in to another
Computer Graphics methods are used in making music videos ,games ,cartoon movies ,television shows etc .
Some times the graphics scenes are displayed by themselves and some times graphics objects are combined with the actors and live scenes
Computer Graphics techniques have been used as an effective educational aid
Models of physical and Physiological systems can assist trainees to understand the operations of the systems
Special Systems are designed for some training applications such as simulators for practice sessions or training of ship captains ,aircraft pilots , heavy equipment operators and air traffic control personnel
Scanning large sets of data to determine trends and relationships is a difficult procedure.
If the data is available in a visual form then the data can be classified in terms of
Scientific Visualization
Business Visualization
It is an area that uses computer graphics to summarize the financial ,statistical ,scientific ,managerial and mathematical reports
It is also used to generate 35 mm slides for the projectors
