Today computer graphics are used in diverse areas such as
science, engineering, medicine, business, industry, government, entertainment, advertising, education, training, etc.
Computer graphics are used mostly in design processes, particularly for engineering and architectural systems,
But almost all products are now computer designed. Referred to as CAD.
use of computer graphics in Design.
Computer-aided design methods are now routinely used in the design of buildings, automobiles, aircraft, watercraft, spacecraft, computers, textiles and many other products.
In CAD, products are designed so that the internal structure and working of every part is checked during design, performance of final product is checked in virtual-reality environment.
Architects use interactive graphics methods to lay out floor plans, that show the positioning of rooms, doors, windows, stairs, shelves, and other building features.
Realistic displays of architectural designs, permit both architects and their clients
to study the appearance of a single building or a group of buildings, such as a campus or industrial complex.
With virtual-reality systems, designers can even go for a simulated walk through the rooms to better appreciate the overall effect of a particular design.
Other major application areas of computer graphics are:
Computer graphics are used to produce illustrations for reports or to generate slides or transparencies for use with projectors.
Presentation graphics is commonly used to summarize financial, statistical, mathematical, scientific and economic data for research reports, managerial reports, consumer information bulletins and other types of reports.
Examples of presentation graphics are bar charts, line graphs, surface graphs, pie charts, and other displays showing relationships between multiple parameters.
Use of computer graphics in Art.
Artists use a variety of computer methods, including special-purpose hardware, artist’s paintbrush programs,
other paint packages, specially developed software, CAD packages, animation packages etc.,
that provide facilities for designing object shapes and specifying object motions.
Besides use of computer graphics in fine arts, it is also used in commercial art for logos and other designs,
page layouts combining text and graphics, TV advertising spots, and other areas.
Application of computer graphics in Entertainment.
In Entertainment companies, motion pictures are created using computer graphics, music videos and television shows.
Sometimes actors and live scenes are combined with graphic objects.
There are several other fields such as Education and Training, visualization, image processing in which computer graphics has its applications.
