How 3D Works• Binocular Vision
• ancient Greece – Euclid• Eyes are 2 inches apart• Each ‘sees’ slightly
different picture• Brain puts it together to
provide depth
How 3D Works• We can simulate this by viewing two pictures
taken from slightly different angles while cross-eyed
RED / BLUE (anaglyph) 3D• When light passes through a red
or blue filter, it filters out that particular wavelength of light
• Taking advantage ofthis and combiningit with binocular visionwe get basic 3D glasses
Polarized 3D• Polarizing the two
different images projected on the screen allows us to do this in a different way
• Does not distort color
New TV’s• Different Type of Technology…
The Active “blocking” method
Lenticular Displays
