How 3D Film Technology Works

HOW 3-D WORKS Anaglyph (red/blue glasses) Two images are displayed onto a screen, one for each eye (can be displayed on screen in many ways, projectors used for clarity) wo different images have slightly different perspectives The Each lens will block a different layer in the eye they are covering and each eye will see a different image Your visual cortex combines these views and your brain perceives this as a 3-D image Polarized 3-D Glasses Similar to anaglyph images, 2 images are synced onto one screen The 2 images have different perspectives and different polarizations Each lens of the polarized 3-D glasses allow only one of the polarized images into each eye, filtering out the other Again, your brain combines these two separate images into a one 3-D image Parallax Barrier (no glasses) Two images with different perspectives are interlaced onto a screen simultaneously right perspective left perspective A filter, known as a parallax barrier, has a series of precision slits that allows each eye to see a different set of pixels for each perspective Section A-A LCD Panel Parallax barrier Your brain processes these images into one image to produce the illusion of 3-dimensional space Active Shutter Glasses Two different perspectives are alternately displayed right perspective on a screen left perspective An emitter sends out a signal to the glasses causing one lens to darken over one eye depending on which perspective is being displayed When an image of the right perspective is shown, the shutter glasses will darken over the left eye When an image of the left perspective is shown, the shutter glasses will darken over the right eye The two perspectives alternate and refresh many times per second and the brain will combine these two separate images into one 3-D image

For some people, seeing cool images might be enough. But others might be curious Avatar’s Pandora was brought to life, or how Piranha Fishes looks like to eat you. The answer for both is simple and ...
