3D technology creates the illusion of depth by providing separate images to each eye that the brain interprets as three-dimensional. While 3D may seem like new technology, stereoscopic photography was invented in 1838. There are different methods for delivering separate images to each eye for 3D movies and TV, including anaglyph glasses with red/blue lenses, polarized lenses, and Pulfrich glasses with one dark and one clear lens. Some disadvantages of current 3D include loss of brightness, discomfort from wearing glasses, high costs, and potential for eye strain.

2. Watching movies in the third dimension might seem like
space-age entertainment, but the technology is older than
your great grandfather.
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.

3. 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.
Watching movies in the third dimension might seem like
space-age entertainment, but the technology is older than
your great grandfather.

4. IN Simple Words that We have feel that whatever happens
in 3d effect it is part of our real life.

5. USING 3D GLASSES..
Types…
1> Anaglyph 3D Glasses
2> Polarized 3D Glasses

6. Anaglyph 3D Glasses
Lenses of red/ blue or red/green for
interpreting anaglyph art. Used for viewing
3D comics, 3-D web sites on the
internet, movies and TV, 3D games, printing
and art.

7. Polarized 3D Glasses
Both linear and circular polarizing lenses.
Polarized 3D glasses are used primarily for
3D laser shows, 3d ride simulators,
multimedia displays,

8. Pulfrich 3D Glasses
One dark and one clear lens. Pulfrich 3D
Glasses work with objects or scenes moving
horizontally across the field of view. This is
one of several ways to experience broadcast
TV in 3-D. The Pulfrich method of 3D is used
for TV, video and 3D computer displays.

9. D4RENCES:::

10. •
In a movie theater, the reason why you wear 3D glasses is
to feed different images into your eyes just like a ViewMaster 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 tecquine.

12. Although the red/green or red/blue system is now mainly used
for television 3-D effects, and was used in many older 3-D movies. In
this system, two images are displayed on the screen, one in red and
the other in blue (or green). The filters on the glasses allow only one
image to enter each eye, and your brain does the rest. You cannot
really have a color movie when you are using color to provide the
separation, so the image quality is not nearly as good as with the
polarized system.

13.  The red and blue lenses filter the two projected images allowing only one
image to enter each eye.

14. Cross eyes seperation mehod

15.  Polarization
At Disney World, Universal Studios and other 3D venues, the
preferred method uses polarized lenses because they allow color
viewing. Two synchronized projectors project two respective views
onto the screen, each with a different polarization. The glasses allow
only one of the images into each eye because they contain lenses
with different polarization.

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

new techonology ..**
we can see watch 3d image without 3d glasses.
In 2010 toshiba is made one tv in which above system is
Followed.

A 55-inch version of the ZL2 will be available in
Europe in December 2011 called 55ZL2. It is
expected to cost around 8000 Euro. A different
variant is expected in the US and Asia in 2012.

22. It is no secret that students of today live in a multimedia
world where they use video as their primary form of
engagement
and
communication.
Teachers
and
administrators are looking for ways to present information
to students that will not only spark their interest, but also
encourage them to explore a subject more thoroughly.
Meaningful
understanding,
exploration
which
usually
translates
means
into
higher
deeper
student
achievement, whether measured via standardized tests or
an increased graduation rate.
The advent of affordable 3D technology promises to bring into
reality the dream of fully engaged students. Are you ready?

What are the disadvantages of 3D Cinema/Television?
Valid disadvantages of current 3D technologies are:
1) Watching 3D content will always result in loss of
brightness in some form or another regardless of what 3D
technology you are using (e.g. polarized, shutterglass, etc.)
2) The glasses are uncomfortable for people who don't
normally wear glasses, because those people are not used
to wearing glasses and the novelty of it becomes a point of

24. 3) The glasses are uncomfortable for people who do
normally wear glasses, because the 3D glasses must be
worn over those existing glasses (unless 3D clip-on lenses
are
4)
used)
Shutterglass
3D
technology
requires
on-going
maintenance (e.g. replacing or charging batteries). Passive
3D technology does not require much maintenance, but it is
also rare to find on the consumer market (despite being the
most popular choice for commercial theaters in North
America).
5) The cost of adding or replacing shutterglasses for
consumer 3D TV is expensive (e.g. $150 per pair)

25. 6) For standard Cable TV broadcasts, it is not possible to
achieve 1080i High Definition for 3D content using the
existing cable TV standards. Instead, 3D content is
broadcast in a lower resolution format (still looks good
though).
7) 3D content can in some cases cause varying degrees of
eye-strain to some viewers, especially after watching for
long periods of time.
