2. Why Computer graphics
– Graphics is cool
• I like to see what I’m doing
• I like to show people what I’m doing
– Graphics is interesting
• Involves simulation, algorithms,
architecture…
– Almost no area in which graphical displays
cannot be used

3. Why should we study Graphics?
• Many of the
leading scientists
through the ages
have been ‘visual
thinkers’…
– Leonardo da
Vinci
– Einstein
– Clerk Maxwell

4. Graphics Applications
– Computer Aided Design (CAD)
– Presentation Graphics
– Computer Art
– Entertainment
– Education and Training
– Visualization
– Image Processing
– Graphical User Interfaces (GUI)

5. – Computer Aided Design
(CAD)
– Design buildings,
automobiles, aircraft,
watercraft, spacecraft,
computers, textiles, and
many other products
– Wireframe & Surface
Rendering
– Simulation of Vehicle
Performance

8. Presentation Graphics
– Illustrations for reports
– Summarize financial, statistical,
and economic data for research
reports, managerial reports,
consumer information bulletins,
and other types of reports.
– Presentation Slides
• Bar charts, Line graphs, Pie charts,
etc.,
– Project Management (Schedule
& Progress)

9. Computer Art
– Fine Art & Commercial Art
– Designing object Shapes and
specifying object motions
– Paintbrush programs (Lumena,
PixelPaint, SuperPaint)
–
–

–
Mathematics Packages (Mathematica)
Animation Packages (Anim8or, Swish,..)
Graphics Tablet (Digitizer) & Stylus
Moving Objects (24 frames per second)

10. Fractals
– A fractal is "a rough or fragmented geometric shape
that can be subdivided in parts, each of which is (at
least approximately) a reduced/size copy of the
whole".
– The term was coined by Benoît Mandelbrot in 1975
and was derived from the Latin fractus meaning
broken or fractured.
10
12. Even 2000 times
magnification of the
Mandelbrot set uncovers
fine detail resembling the
full set.
A fractal that models the
surface of a mountain

13. Entertainment
– Motion pictures, music videos,
and television shows.
– Sometimes
the
graphics
scenes are displayed by
themselves, and sometimes
graphic objects are combined
with the actors and live scenes.
– Morphing

14. Motion Pictures
Series of still photographs on film, projected in rapid
succession onto a screen
World's first motion
picture film by Louis Le
Prince, 1888

15. Morphing
Morphing is a special effect in motion pictures and
animations that changes (or morphs) one image into
another through a seamless transition

16. Education and Training
– Computer generated models of
physical, financial, and economic
systems are often used as
educational aids.
– It
helps
the
trainees
to
understand the operation of the
system.
– Simulators for practice sessions
or training of ship captains,
aircraft pilots, heavy equipment
operators, and air traffic-control
personnel.

17. Simulation
A simulation is an imitation of some real thing,
state of affairs, or process.
Wooden mechanical horse

19. Visualization
– Scientists, engineers, medical personnel, business analysis,
and others often need to analyze large amounts of
information or to study the behavior of certain processes. –
tedious & Ineffective
– To overcome this, a technique which trends and patterns
apparently is used called visualization.
– Numerical modeling of thunderstorms, Protein modeling,
Molecular structure, an air pollution study, etc.,
– Scientific Visualization
(stored as graphics packages
for scientific studies)
– Business Visualization
(stored as data sets for commerce
applications)
