Anaglyph

Polarization

Eclipse Method

Interference filter technology

Pulfrich

Spectral separation

Lenticular or barrier screen

Earliest method

Introduced in 1915

Superimposing two images, one left eye

oriented (RED) another right eye (CYAN)

Can be used in TV broadcasting easily

Actual color is not recreated successfully

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 our brain does the restrest

The active shutter glasses required for the 3D technology is categorized into two main kinds which are called as…

liquid crystal shutter glasses

display glasses.

Polarized at 45 degree and 135 degree (90 degree difference)

RealD glasses

Circular polarization preferred over linear, since viewer need not to align himself/herself according to the image orientation

4K projector projects 2K images on screen

Metallic screen makes it effective (silver screen), polarization not destroyed, introduced by Thomson Technicolor.

It reduces overall image brightness and contrast.

Projection of Images working of polarizing glasses

LCD Shutter glasses are used

Do not require silver screen

Brightness and contrast maintained

LCD valves the work by rotating the light between two opposite polarizing filter

Expensive glasses

Different wavelength of RED CYAN BLUE for each eye (Dolby 3D)

Appropriate filters for each eye

PANAVISION introduced 5 filter per eye ove r Dolby 3D

Claims to be cheaper than Dolby 3D and can be viewed on almost all projectors and screens unlike Dolby 3D

Based on human eye sensitivity for different light intensity

Body moves from left to right at some pace and left eye covered with darker lens

It creates a two images illusion

Not widely used

Uses holographic film in glasses that create dispersive prism like effect

Causes “redder” objects perceived as near then “bluer” objects

Superimpose two images

Same sheet

Alternating strips

Screen having narrow lenses allows one image to be shown at some particular angles (using parallax)

Lenses when made cylindrical reflects light at acute angle

Viewer have to sit at an angle about 90 degree

Restricts number of viewers

Not widely in use

Without glasses

Autosterioscopic LCD screens

Introduced by “Sharp” in 2004

Autosterioscopic mobile screens by Japan in 2009 (Hitachi)

Gaming devices: Nintendo 3DS

A motion film standard

70mm film projection

8 stories high screen (silver light)

One of the best 3D experience

STRENGTHS•Unique experience (realistic feel)

•Companies producing 3D flat displays

are well-known in the industry such as

Sony and Toshiba

•Partnerships – with movie industry

•Wide coverage of technology

•Wide array of R&D teams

WEAKNESSES•Costly

•Slow development of underlying

technology

OPPORTUNITIES•Technology on the rise

•Technology trigger (booming)

•Improving economy

•Industry competition

•Publicity

THREATS•Leakage of critical information

•Piracy of employees

•Fast-phased technological environment –

can be easily phased out
