For centuries man has tried to develop imaging techniques that can mimic the 3D stereo visual perception, so that the illusion of depth can be recorded and experienced later. The science associated with this reproduction of three dimensional information using two separate images is known as Stereoscopy.





Humans view the world in three dimensions and this is possible due to the binocular vision (vision through two eyes). The left eye and the right eye view things a bit differently due to the difference in perspective. It is this parallax of vision that results in the final 3D image that forms in the brain.




It is on this same fundamental that 3D stereo visual reproduction is based, in all the numerous attempts until now. We shall have a look at how things took shape over the course of years, starting from no-tech as we go to hi-tech.

I just couldn't get the 3D image on page 2, in spite of looking at it for 15 mins... Could you give me a hint and tell me at which spot should I be focussing on? Coz I too wanna join in the fun :)

1. Hold the picture up to your nose and relax your focus. 2. Your eyes should be focused afar. Do not try to focus on the picture. 3. Slowly pull the picture away from your face, while still maintaining a distant focus. 4. Allow the picture to come into focus. 5. Repeat 1-4 until this works. Tips * To practice keeping your eyes focused far away, hold the picture in front of one eye while the other eye holds the focus on distant objects in the room. * The key is to keep your eyes relaxed. Relaxed eyes will come into position such that * You are not technically crossing your eyes to view the picture, but forcing them to view two different pictures, due to the spacing of the pattern in the stereogram. * A small segment of the population does not have stereovision, and will not ever be able to view stereograms. * It often takes several tries to get it (perhaps 30 minutes or more!), but once you see your first one, the others will come easier! * If you get good enough, you don't even have to move the picture or your face, you can just cross your eyes correctly and it will appear. * If you feel your eyes manually focusing, start over at step 1.

Also check DOLBY 3D & REAL D solutions for THEATRical experience. Unfortunately DOLBY 3D theater are not there in INDIA as of now. We missed ICEAGE3, Up in 3D.
