The document discusses various topics related to 3D technology including its history, how 3D images can be viewed using different types of 3D glasses, applications of 3D technology, and how 3D has changed our lives. It provides details on the evolution of 3D technology from early 3D movies in the 1920s to current uses in areas like 3D printing, gaming, and medical imaging. The key aspects of 3D technology covered are its ability to create the illusion of depth and how polarized lenses and different lens filters allow each eye to see a separate image that the brain combines into a 3D perception.

3. Dimension?
Width, depth and height
are dimensions .
e.g. A line has one
dimensions , a square has
two dimensions and a cube
has three.
3D (3 dimension)?
The quality of being
three-dimensions.
Some General information

4. Introduction to 3D technology
3D technology stands
for three-dimensional
technology.
3D technology is the
illusion of depth.it is a
visual representation
system that tries to
create or reproduce
moving objects in the
third dimension.

5. In simple that we have feel that
whatever happens in 3D effect it is
part of real life.

8. History of 3D technology
First 3D movie

Love”
1980 William Frieze

patent

9. How we can see 3D images
 We can see 3D image using
3D glasses
Types of 3D glasses
1) Anaglyph 3D Glasses
2) Polarized 3D Glasses
3) Pulfrich 3D Glasses

10. 1) Anaglyph 3D Glasses
 Lenses of red/blue or red/green for
seeing anaglyph art.
 Used for viewing
3D comics
3-D web sites on the internet
3D movies and TV
3D games,
3D printing and art.

12. Both polarizing lenses have
gray color .
Polarized 3D glasses are used
for
3D laser shows,
3D flight Simulators,
3D multimedia displays.
2) Polarized 3D Glasses

14. One dark and one clear lens.
Pulfrich 3D glasses work with a object
or scenes movies horizontally across the
field of view.
 The Pulfritch 3D Glasses is used for
 3D video.
 3D TV .
 3D computer displays.

Working of Anaglyph Glasses
Working of Pulfrich glasses

17. On the screen ,two
images one blue
and one red is
displayed
The lenses only let
one image into each
eye
Working of Anaglyph Gla

18. Working of polarized glass
Polarized
lenses are both
have gray
color

19.  The lenses are
specially cut at
opposing 45 degrees.
 Two images are
projected on the
screen and each one
has a different
polarization

20.  The polarized
glasses allow only
one of the images
into each eye
because each lens
has a different
polarization.

21. These glasses use the
concept of one dark and
one light lens to form 3D
images
The image through the
dark lens reaches the
brain slightly after the
image that went through
the clear lens, creating a
3D illusion

27. The user log-in by
navigating through

The password is a

35. 1. Holography (from the Greek, whole + write)
is the science of producing holograms
invented by Dennis Gabor
2. It is an advanced form of photography that
allows an image to be recorded in three
dimensions
3. The technique of holography can also be
used to optically store, retrieve, and process
information

40. 3D tattoos
3D tattoos add a new dimension to Tattoos
Art .
A 2D-Tattoos are flat images with no depth in
the tattoos design.
But a 3D-Tattoos refer to Tattoos that have an
extra dimension.
3D-Tattoos interact with the skin, giving the
illusion of being above the skin or within the
body,

42. A 3D Movies (also known
as three-dimensional film, 3D
film ) is a motion picture that
enhances the illusion of depth
perception by adding a third
dimension.

3D Movies

44. A 3d films are captured using two lenses placed
side by side , just like your eyes ( or by producing
computer generated images to repeat the same
effect )
In old fashioned 3D films :-
a)Shots for left eye would be filmed using a red
lens filter, producing a red image ,
b)And shots for the right eye would be shot using
a blue filter, resulting in a blue image .
Two projector then superimposed the image on
cinema screen.

45. How 3D change our life
 In making 3D films…

46. In Making 3D display of television..
Making 3D games

ii. Bat man

47. Developing 3D body
measurement and
body scan
Used to increase
safety measures
Invasive
May violate privacy
For security reason

48. In medical field
Reprint Rather Than Wait For Organs
Not only can we use 3D printing to create art, we
can also create real life!
A 3D printer can also be used to pile organic matter,
systematically layer by layer to build tissue and
organs

49.  The majority of plastics
used today are non-
biodegradable and
poses a threat to the
environment.
 Exocyclic Cube is an
example of a 3D
printer that will only
accept special, recycled
plastics.
Helps Reduce Plastic Waste

50. 1. Watching 3D content will always
result in loss of brightness
May damage eyesight
May cause:
motion sickness
eye strain
Loss of brightness
Drawback of 3D technology

51. 2) The glasses are uncomfortable for
people who don’t normally wear
glasses.
3) The glasses are uncomfortable for
people who do normally wear glasses
because the 3D glasses must be worn
over those existing glasses.
