August 15, at am. The silver screen on which the film is finally projected absorbs the excessive light generated because of the high frame rate display.
Thus the glasses used for such a viewing have a slightly dark set of lenses which absorb the unwanted light thrown by the projector lamp. If there are rapid transitions between scenes, viewers may experience motion sickness or nausea. Find latest and upcoming tech gadgets online on Tech2 Gadgets.

OnePlus Nord 2 review Return of the flagship-killer. Saturday, November 13, Back to. You see cars flying toward you or snowflakes floating in the air all around you. Isn't modern technology amazing? How do they do that? People perceive depth and see the real world in three dimensions thanks to binocular vision.
No, we don't look through binoculars! But we do have two eyes that are about three inches apart. The separation of our eyes means that each eye sees the world from a slightly different perspective. Our powerful brains take these two slightly-different images of the world and do all the necessary calculations to create a sense of depth and allow us to gauge distance.
Try these simple experiments to test your binocular vision. Hold one arm straight out in front of you with your thumb pointing up. Close one eye and stare at your thumb. Now close the other eye. What do you see? As you close one eye and then the other, you should see your thumb appear to move slightly against the background.
Think binocular vision doesn't make much of a difference? Grab a ball and ask a friend to toss it to you. Practice catching the ball a couple of times. Then, keep one eye closed and try to catch the ball. Do you notice how much harder it is to gauge distance and catch the ball? Scientists have a fancy word for how your eyes and your brain work together to see in three dimensions.
It's called stereoscopy. Stereoscopy is what modern 3D technology tries to duplicate. There are several different types of 3D technology in use today, but they basically do the same thing.
Depending upon the exact type of technology used, the 3D glasses you wear will either use special shutters, color filters, or polarized lenses to receive the images. Your brain takes care of the rest! For example, older and some newer 3D movies have to be viewed through special red and blue sometimes red and green glasses.
Images are projected in those colors — red and blue — and the special glasses make sure each eye only receives one of the images. As always, your brain puts the 3D effect together. Newer movies use polarized glasses that take advantage of the fact that light can be polarized, or given different orientations. Newer 3D glasses with polarized lenses don't need separate colors and can give a much more lifelike experience.
Your incredible brain does all this 3D processing automatically. It's a fantastic machine! The hardest part for 3D movie makers is getting a camera to do the same thing, so that they have the right images to send to your eyes via the movie screen. To get a good 3D image, you have to have two versions of the same image filmed from the exact angle as your eyes would see it.
To accomplish this, filmmakers use special film rigs that use two cameras bolted into position to mimic human eye position.
To make an animated movie in 3D, animators do basically the same thing. They create two versions of each individual picture to duplicate the perspective of each individual eye.
Although it's easier to get perfect images, it also takes a lot of extra time to create all the extra images. Wouldn't life be boring if it was only in two dimensions?
That third dimension adds so much fun to everything! Find a friend or family member to help you explore these fun three-dimensional activities:. I really like your videos I hope you make more.

We hope you've enjoyed our many Wonders! Hi, Brandon! We are sure that is probably uncomfortable. We don't think there are any 3D contact lenses, but you never know what the future holds. Maybe you could try regular contacts, then use the 3D glasses.
Hi, Kendra w.! Going to the movies is always fun! You can also submit your ideas to "what are you wondering? Hello, Kevin McMurtrie! You're right, 3D glasses have also transformed rides and attractions at theme parks. Thanks for sharing your opinion, Nancy H.! We understand! A regular movie is just as good! Your welcome, Tionna Pearson!
Have fun at the movies and enjoy the 3D technology! Thanks for the feedback, Cody! The new Wonders are submitted by Wonder Friends, just like you! You can add your ideas to the Wonder Bank! Thanks for your comment, Cole H! Unfortunately, the 3D goggles do bother some people. Maybe as the technology improves, the glasses will, too. We hope you're enjoying your day! Thanks for sharing that interesting fact, zack! That's awesome, Kristopher! We love going to the movies, too. Dear lucy l, It is great to have goals and dreams for when you grow up.
Thanks for commenting! How are you? Maybe you could do more research about 3D glasses at your library! Dear Makena M.! Have fun exploring Wonder Where Is Wonderland? Welcome, Taylor!
