Computer graphics involves using computer programs and hardware to create digital images and animations. It allows for the creation and manipulation of geometric objects and their images. Computer graphics is used in many fields including design, presentations, education, visualization, image processing, and graphical user interfaces. Common applications include CAD, illustrations for reports, charts and graphs for data summaries, cartoons, advertisements, and visual effects in movies.

1. •It is an art of drawing , pictures , lines, charts etc., on computer
screen by using program Language.
•Creation , Manipulation and Storage of geometric
objects(modeling) and their images(rendering)
•Others: GUI, Display etc.,

2.  High quality graphics display on Personal
Computer
 Provides the tools to produce the picture.
 Produce animations

3.  Computer – Aided Design
 Presentation Graphics
 Computer Art
 Entertainment
 Education and Training
 Visualization
 Image Processing
 Graphical User Interfaces

4.  Used in design of buildings , automobiles ,
aircraft, spacecraft, computers, textiles &
many other products.
 Software packages provide multi-window
environment.

5.  Use to produce illustration for reports or generate
slides for use with projectors
 Commonly used to summarize financial,
Statistical, mathematical , Scientific , economic
data for research reports, managerial reports &
customer information bulletins
 Eg: Bar charts , Line graphs, Pie charts, Time
chart etc.,

7.  Includes artist’s paintbrush programs,paint
packages, Cad packages and animation packages.
 These packages provides facilities for designing
object shapes & specifying object motions.
 Examples : Cartoon drawing, paintings, product
advertisements, logo design

8.  Electronic painting
 Morphing
A graphics method in which one object is
transformed into another.

9.  Movie Industry
Used in motion pictures , music videos ,
and television shows.
Used in making of cartoon animation
films.

10.  Computer-generated model of the physical,
financial and economic system is often used as
educational aids. Model of physical systems,
physiological system, population trends or
equipment can help trainees to understand the
operation of the system.

11.  Scientific Visualization
 Producing graphical representations for scientific,
engineering and medical data sets.
 Business visualizations is used in connection with
data sets related to commerce, industry and other
non- scientific areas
 Techniques used –color coding , graphs, charts ,
surface rendering & visualization of volume
interiors.
 Image processing techniques are combined with
computer graphics to produce many of the data
visualizations.

12.  Image processing deals with cleaning up noisy
and blurred images & creating clear picture.

13.  A major component of a graphical interface is a
window manager that allows a user to display
multiple window areas.
 The icons represent options for painting,
drawing, Zooming, typing text strings, and other
operations connected with picture constructions.
