This document provides an overview of computer graphics. It discusses the history and evolution of computer graphics from the 1960s with early pioneers like William Fetters capturing 3D human structures. In the 1980s, microprocessors enabled higher resolution graphics terminals. 3D graphics became more popular in the 1990s for gaming, multimedia, and animation. The document defines computer graphics as the creation, manipulation, and storage of geometric objects and images. Examples of vector and pixel images are shown. Applications of computer graphics include CAD, simulation, animation, visualization, and video games.

3. • The term computer graphics refers to "almost everything on computers
that is not text or sound”
• Refers to creation, Storage and manipulation of pictures and drawing
using a digital computer.
• Effective tool for presenting information.
• Computer aided design.
• Computer aided manufacturing.

4. What is Computer Graphics?
• Creation, Manipulation, and Storage of geometric objects (modelling) and
their images (rendering).
• Display those images on screens or hardcopy devices
• Image processing
• Others: GUI, Haptics, Displays (VR) etc

5. • In 1960, William Fetters a
graphic designer for Boeing
Aircraft Co. proposed his 3D structure of the human
body. This structure was
called “Boeing Man”.
William Fetters
1928 - 2002

6. He did so by drawing the 3-D structure of the
human body, then scanning them to create
images in a 2-D environment such as the
computer screen.

8. In the same year General
Electric
launched
a
computer named “TX-2”
specially designed for
graphic generation.
This computer used “Motion Capture” to
generate 3-D representation of moving
objects like the human body.
It also used a lightpen and a scanning pad
to draw 3D structures.
Motion Capture is the process of
recording movement onto a
digital model like the TX-2.

9. Cont...
In the early 1980s, the
availability of bit-slice and 16bit microprocessors started to
revolutionise high resolution
computer graphics terminals
3D graphics became more
popular in the 1990s in gaming,
multimedia and animation.
computer graphics have only become
more detailed and realistic, due to
more powerful graphics hardware and
3D modeling software.

11. Images
In common usage, an image or picture is an artefact, usually
two-dimensional, that has a similar appearance to some
subject - usually a physical object or a person.

12. IMAGES

13. Examples..
Vector Image
Pixel Art Image

15. Computer Animation
• Computer animation is
the art of creating moving
images via the use of
computers.
• Computer animation is
also referred to as CGI
(Computer-generated
imagery or computergenerated
imaging), especially when
used in films.

16. • Images are typically taken by devices such as cameras, mirrors, lenses,
telescopes, microscopes, etc. Digital images include both vector images
and raster images, but raster images are more commonly used.
• The following information should help you get started in the field of
computer graphics:
 Pixels
 Graphics
 Rendering
 Modeling
 Display or Visualization

18. • A Graphics Processing Unit or GPU is a dedicated graphics
rendering device for a personal computer, workstation, or game
console.
• It is of two types: a) Integrated
b) Dedicated
Dedicated GPU
Integrated GPU

19. • Graphics Driver is a
collection of
application programs
for handling tasks
related to
multimedia,
especially game
programming and
video. For example
The Direct X.

20. EXAMPLES or APPLICATIONS
OF
MODERN GRAPHICS

21. There are a variety of uses for computer animation. They can
range from fun to practical and educational ones.
•Computational physics
•Computer-aided design
•Computer simulation
•Digital art
•Education
•Graphic design
•Infographics
•Information visualization
•Rational drug design
•Scientific visualization
•Video Games
•Virtual reality
•Web design
•Computational biology

26. The world of computer graphics
concentrate on reinforcement of
performance and the better
techniques to bring reality in its
output.
