3D is the new technology of the video. But they require you to wear expensive glasses to view them. Would you like to view 3D videos without glasses?As the topic suggest you do need to have 3D glasses to view 3D. So what do you need? Actually you don’t need anything except a colour display. :PBefore we continue here is a brief introduction to what we are doing. Strongly suggest you to read before you continue.
3D photography and videos also known as Stereo videos and photographs require two pictures, one for each eye. As the way you see real world objects. When you see real world objects you see the same image from both eyes but slightly different in angle due to difference in between eyes.As normal visual, in this 3D vision, the pictures must be presented to your eyes so that each eye sees only the picture intended for it. Generally two methods are used: Both methods require one to learn a new visual skill.Normally when we look at the "real" world, our eyes converge on an object in the scene and they also focus on that same object. We habitually do this, and our brains have become accustomed to a one-to-one correspondence between focus and convergence.We can learn to "unlock" focus and convergence, enabling us to view stereo pairs without optical aid. In this tutorial we use a display method which can be adapted to either parallel-eye viewing or crossed-eye viewing. Three pictures will be shown side by side. The middle one is to be viewed with the right eye. The other two are identical and one is to be viewed with the left eye. Here's how to view them.(1) Parallel viewing. This is sometimes called wall-eyed viewing. Use the left and middle pictures only. Look at a distant object then bring your eyes down to the paper trying not to converge or focus on the paper. You'll see a blurred double image. Consciously try to bring the double image into one. Now try to focus your eyes on it without allowing the two images to drift apart.Parallel viewing is limited to pictures about 2.5 inches wide, the spacing of the typical human eye (which averages 65 mm).(2) Cross eyed viewing. Use the right and middle pictures only. Hold your finger exactly halfway between your eyes and the page. Focus on your finger. Your eyes will be converged on the finger also, and you should be conscious of the two pictures out of focus behind your finger, but probably nearly coincident. Move your finger a bit until the two pictures are fully coincident. Now hold that convergence while refocusing from your finger to the page. Finally, you can remove your finger from the field of view.Crossed eyed viewing can be used with even larger pictures. Paintings have been presented this way. Salvadore Dali painted some of this kind. For those who can learn the skill of viewing, this is one of the most effective ways for viewing stereo without special glasses. (2) Mirror method. For completeness, we illustrate a method rarely used in printed books. Popular Photography magazine experimented with it for a while. One picture of the pair is printed normally, ad the other is printed beside it, but reversed left/right. That picture is viewed through a mirror which re-inverts it. We will not use that method here. You can use the above techniques to view the below image
After all those stuff it is time to move into an actual image and feel the 3D. Below are some of the pictures I got from the internet. You can view them in 3D using cross eye technique.
You can find galleries of 3D images at You can find thousands of other sites where you can view 3D image gallery.When moving on to video, it is very tricky. But the methodology is the same. You can view them on all the techniques mentioned above. Youtube recently launched an their 3D videos and users can upload their 3D videos to youtube now. But before we watch them here is a video uploaded before youtube launched 3D.
It is time to switch to 3D mode in youtube. It is just 2 simple steps· First go to Select 3D Mode on youtube. And select “View video with no 3D device”· You are ready to view 3D. Try one of the following videos. (You will notice there is a new menu before the resolution menu on youtube lower panel when you are watching a 3D video)Here is a 3D video channel.
