Why Study Computer Graphics?

Definition
Computers accept process, transform and present information.
Computer Graphics involves technology to accept, process, transform and present information in
a visual form that also concerns with producing images (or animations) using a computer.

Why Study Computer Graphics?
There are certain important reasons to study computer graphics. We will discuss them under
certain heads:

a. Visualization
I like to see what I am doing. Many a times it happens that you perform certain tasks which you
cannot visualize; for example as a student of data structures, you implement trees, graphs and
other Abstract Data Types (ADTs) but you cannot visualize them whereas you must be having an inner quest to see what these actually look like.

I like to show people what I am doing. Similarly at certain times you would be performing certain
tasks which you know but it would be difficult for others to understand them so there is very
important requirement of showing the things in order to make them understandable.

b. Graphics is interesting
We are visual creatures and for us a picture is worth a thousand words. If we can get rid of text
based static screen and get some graphics; its always interesting to see things in colours and
motion on the screen. Therefore graphics is interesting because it involves simulation, algorithm,
and architecture.

c. Requirement
Well there are certain areas which require use of computer graphics heavily. One example is
drawing of machines. It is required to prepare drawing of a machine before the actual production.The other heavy requirement is for architects as they have to prepare a complete blue print of the building they have to build long before the actual construction work gets underway. Autocad and other applications of the kind are heavily used today for building architecture.

d. Entertainment
Merely a couple of decades back, the idea of a 24 hours Cartoons Network was really a far
fetched one. That was the time when one would wait for a whole week long before getting an
entertainment of mere 15 minutes. Well thanks to computer graphics that have enabled us to
entertain ourselves with animated movies, cartoons etc.
