2. Computer graphics is using computers to generate and
display images.
It is about how to program a computer to generate
photo-realistic images.
Computer graphics are graphics created
using computers and the representation of image data by
a computer specifically with help from specialized
graphic hardware and software.
3. 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
4. Many of the leading
scientists through the
ages have been ‘visual
thinkers’…
-Leonardo da Vinci
-Einstein
-Clerk Maxwell
5. Interactive Graphics
In interactive computer
graphics user have some
control over the picture
i.e user can make any
change in the produced
image.
Passive Graphics
A computer graphics
operation that transfers
automatically
and
without
operator
intervention.
Noninteractive
computer
graphics involves one
way
communication
between the computer
and the user.
