6. History:
• Watching movies in the third dimension
might seem like space-age entertainment, but
the technology is older than your great grand
father.
• According to sensio, a Canada-based
manufacturer of 3D home Technology
“Stereoscopic photography, or the technique
of creating a ‘Third dimension’ was first
invented in 1838”.

7. Introduction:
• 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,
• In simple that we have feel that whatever happens in 3D effect it is part of
our real life.

8.  Working of 3d technology:
• In a movie why you wear 3D glasses is to
feed different images in your eyes just
like a View-Master does.
• The screen actually displays two images,
and the glasses cause one of the images to
enter one eye and the other to enter the
other eye.
• There are two common systems for doing
this.
• It is called stereoscopic technique.

10. 3d glasses:
• The illusion of three dimensions on a two-dimensional surface can be
created by providing each eye with different visual information. 3D
glasses create the illusion of three dimensions by filtering a signal
containing information for both eyes.
• The signal, often light reflected off a movie screen or emitted from an
electronic display, is filtered so that each eye receives a slightly different
image. The filters only work for the type of
signal they were designed for.
• Theses are of following types:
1. Anaglyph 3D Glasses
2. Polarized 3D Glasses
3. Pulfrich 3D Glasses

11. 1. Anaglyph 3d glasses:
• Anaglyph 3D glasses have a different colored
filter for each eye, typically red and blue or red
and green.
• Lenses for interpreting anaglyph art.
• Used for viewing:
o 3D comics,
o 3D websites on the internet,
o 3D movies and TV,
o 3D games,
o 3D printing and art.

12. 2. Polarized 3d glasses:
• A polarized 3D system on the other hand uses polarized filters.
• Polarized 3D glasses allow for color 3D, while the red-blue lenses produce
an image with distorted coloration.
• An active shutter 3D system uses electronic shutters. Head-mounted
displays can filter the signal electronically and then transmit light directly
into the viewer's eyes.
• Both linear and circular polarizing
lenses.
• Polarized 3D glasses are used for:
o 3D laser shows
o 3D ride simulators,
o Multimedia displays.

13. 3. Pulfrich 3d glasses:
• One dark and one clear lens, Pulfrich 3D glasses work with a object or
scenes movies horizontally across the field of view.
• This is one of several ways to experience broadcast TV in 3D.
• The Pulfrich method of 3D is used for TV, video and 3D computer
displays.

14.  Companies:
• Apple
• Toshiba
• Samsung
• Sony
• Panasonic
• Sharpe
• LG

16.  devices:
• 3D TV
• 3D gaming devices
• 3D mobile phones
• 3D printer
• 3D camcorder

17. • 3d TV:
• 3D TV is a TV that display 3 dimensional
effect.
• In human eyesight the perspective difference
between objects seen through the left and
right eye, 3D TV presents two separate
images, 1 for left and 1 for right eye by the
use of specialized glasses.
• TV display technology includes LCD, LED
and plasma.
• It mimics the way your eyes and brain view
the world.

18. • 3D gamming devices:
• 3D gaming is interactive computer entertainment
that is graphically presented in the three
dimensions of height, width and depth; the
addition of depth to 2D gaming enabled the
exploration of virtual worlds with more realistic
representation.
• The first true 3D games were developed from wire
frame3D gaming is interactive computer
entertainment that is graphically presented in the
three dimensions of height, width and depth; the
addition of depth to 2D gaming enabled the
exploration of virtual worlds with more realistic
representation.

19. • 3D Mobile:
• 3D mobile is a mobile phone that conveys
deep perception to the viewer by employing
3D depth techniques.
• 3D mobile have 3D camera and 3D output
via HDMI.
• World’s first 3D commercial was on aired in
Japan.
• Some mobile phones have built 3D ability.

20. • 3D printers:
• ‘A machine allowing the creation of a physical
object from a three-dimensional digital model,
typically by laying down many thin layers of a
material in succession.’
• A 3D printer is a computer-aided manufacturing
(CAM) device that creates three-dimensional
objects.
• Like a traditional printer, a 3D printer receives
digital data from a computer as input. However,
instead of printing the output on paper, a 3D
printer builds a three-dimensional model out of a
custom material.

21. • 3D Camcorder:
• 3D camcorder is a camcorder that is capable
of recording 3D video.
• 3D pocket camcorder has 2 lenses and 2
sensors.
• 3D image may be seen in the parallax barrier
LCD panel without glasses.
• In 2010 Panasonic announced the 1st 3D
digital video camera.

23.  Interesting facts:
• Worlds no 1 company Apple declared that it will make 3D IPod, and
Laptop.
• World’s famous company Toshiba found that New Technology we Can
see 3D images without 3D glasses.
• In 2010 Toshiba has made one TV in which above system is Followed

24.  Swot analysis:

• Uncomfortable to use

30.  Effects on health:
• May trigger epileptic seizure & stroke
• May damage eyesight
• May cause:
o Motion sickness
o Perceptual after effects
o Disorientation
o Eye strain
o Decreased postural stability

31.  Effects of 3d technology:
1. Watching 3D content will always result in loss of brightness
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.
4. Shutter glass 3D technology requires on going maintenance.
5. Passive 3D technology does not require much maintenance but it
is also their to find on the consumer market.

32.  Sum up:
• Three-dimensional processing is an emerging and growing need
in the multimedia domain.
• In a lot of industries, 3D printing provides countless benefits.
• However, it is not going to replace traditional manufacturing.
• It is still an emerging technology with some disadvantages that
need to be considered when selecting a product development
method.
• Manufacturers and product designers therefore need to see it as
a process to complement traditional manufacturing.
