Computer Graphics
Computer graphics are pictures and drawings produced by computers.
A graphics programme interprets the input provided by the user and
transports it into images that can be displayed on the screen, printed on
paper or transferred to microfilm. In the process the computer uses
hundreds of mathematical formulas to convert the bits of data into precise
shapes and colours. Graphics can be developed for a variety of uses
including illustrations, architectural designs and detailed engineering
drawings.
Mechanical engineering uses sophisticated programs for applications in
computer-aided design (CAD) and computer-aided manufacturing
(CAM). In the car industry CAD software is used to develop, model and
test car designs before the actual parts are made. This can save a lot of
time and money.
Basically, computer helps users to understand complex information
quickly by presenting it in more understandable and clearer visual forms.
Electric engineers use computer graphics for designing circuits and in
business it is possible to present information as graphics and diagrams.
These are certain to be much more effective ways of communicating than
lists of figures or long explanations.
Today, three-dimensional graphics along with colour and computer
animation are supposed to be essential for graphic design, computer-aided
engineering (CAE) and academic research. Computer animation is the
