Your brain puts the two pictures back together and now you’re dodging a flying meteor!ģD glasses make the movie or television show you’re watching look like a 3-D scene that’s happening right in front of you. Here’s where those cool glasses come in - the colored filters separate the two different images so each image only enters one eye. The same scene is projected simultaneously from two different angles in two different colors, red and cyan (or blue or green). Your eyes can correlate these images automatically because each eye sees only one of the images.Ī 3D film viewed without glasses is a very strange sight and may appear to be out of focus, fuzzy or out of register. Two cameras photograph the same image from slightly different positions to create these images. In a View-Master, each eye is presented with an image. If you’ve ever used a ViewMaster™ or a stereoscopic viewer, you have seen your binocular vision system in action. Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different. Therefore, each eye sees the world from a slightly different perspective, and the binocular vision system in your brain uses the difference to calculate distance. The binocular vision system relies on the fact that our two eyes are spaced about 2 inches (5 centimeters) apart. Now you’re learning! Need to know more about how do 3D glasses work? Read on. This is called binocular vision – ViewMasters™ and binoculars mimic this process by presenting each eye with a slightly different image. Your brain then correlates these two images in order to gauge distance. Since your eyes are about two inches apart, they see the same picture from slightly different angles. They simply recreate the way humans see normally. The technology behind 3D, or stereoscopic, movies is actually pretty simple.
The mode of 3D presentation you are most familiar with are the paper glasses with red and blue lenses. Still want to know how do 3D glasses work? Keep reading!Īnaglyphic adjective - A stereoscopic motion or still picture in which the right component of a composite image usually red in color is superposed on the left component in a contrasting color to produce a three-dimensional effect when viewed through correspondingly colored filters in the form of spectacles. The brain then puts the two pictures together to form one 3D image that has depth to it. This is done in the real world by your eyes being spaced apart so each eye has its own slightly different view.
In order to see things in 3D each eye must see a slightly different picture.
Should i keep 3 d viewer full#
Remember the ViewMaster™ that showed all the cool Disney characters in full 3d? The ViewMaster™ allowed you to look at two pictures of the same thing taken from a slightly different view point and tricked your brain into seeing one 3d image. In fact you had them when you were a kid and probably didn’t even know it.
