Skip to content Why Are 3d Glasses Necessary For The Imax Experience Why Cant The Movie Just Be Made In That Specific Way – I was at IMAX on a school trip this week and asked for two pairs of glasses for my class. I asked. I’m not a thief, just like these affordable 3D glasses.
The way IMAX 3D is created is by polarizing the image on the screen so that the light on the left eye is 90° out of phase with the light on the right eye. You can easily demonstrate this by first placing the glasses on top of each other, left lens on top of left lens. You can clearly see the dual lens left and right as in the picture on the right. The photo below shows the left lens of the front glasses over the right lens of the previous pair. The middle pair of lenses is black. You can click on these images to see a full size.

Now turn one lens 90° to the other and cover the left lens with the left lens turned. The glasses are dark now. Move the left lens over to the right lens and the image is clear again. Now repeat this with the correct lens from the beginning. Apparently the left and right lenses are out of phase.

I am not sure how to create this image on the screen. My best guess is that they have a dual projection system that goes through the same polarizing filter. I believe that distance creates depth. If anyone knows for sure, please post the details.
I stopped teaching at the end of 2016 and returned to the industry, not because I was tired of the classroom, but because my wife wanted to travel again.
For many of you struggling to move everything online, or worse, forced into class when science says no, I’m thinking of you and wishing you a healthy year ahead.

Last month my family and I visited Disney World for the first time. Our favorite ride is Avatar: Flight of Passage, a five-minute virtual experience that puts you on the back of a dragon-like banshee to fly over the mountains of Pandora.

I bend and climb in a vibrating chair while looking through 3D glasses at an absolutely massive screen, filling my field of vision with stunning 10K resolution images at 60 frames per second. It was amazing, it made all the expense and hassle of Disney worth it. My daughters loved it too, although it gave them a bit of motion sickness.
On Wednesday, I went to the New York IMAX 3D premiere of Avatar: The Way of Water and felt a similar thrill, and it lasted longer.
My comfortable seat didn’t move and no wind or fog sprayed me like Disney, but the feeling was just as intense. Even with a running time of 3 hours and 12 minutes, director James Cameron’s epic left me in awe of the entire visual experience. Although the plot, rhythm and premise fell short, I did not really mind and the short trip did not spoil the fun.
“As a television critic, I have seen many great films, and Avatar: The Way of Water is one of the best. AMC Lincoln Square in Manhattan, which I have seen, has one of the largest Imax screens in the country at 76 feet wide by 101 feet – about six stories high. The combination of size, 3D depth, smoothness and detail, as well as the absolute otherworldliness of what I saw transported me. There was so much eye candy, sometimes I did not know where to look next My visual cortex was working overtime to process all the action, swimming aliens, high-tech vehicles and explosive hazards.

On the Avatar ride at Disney, I remember looking away from the screen at one point to check on my kids and realizing that next to me, in another room, another group of people were watching the same thing. I don’t think I’ve seen my fellow movie star, colleague Scott Stein, more than once in a movie theater. I was so changed by the program.

Part of the content that drew me in was something I complained about: the high frame rate (HFR) list. Most theaters showing the film won’t have a high-frame-rate presentation, but I saw it the way Cameron prefers IMAX theaters: 3D, 4K resolution and HFR. They actually changed the frame rate from 24 frames per second to 48, which is the standard for most movies, which makes it look smoother, especially on the big screen in 3D.
“The rule is that when they are underwater, it’s 48 frames. Boom. Don’t even think about it. Some flying scenes and some wide views benefit from 48 frames,” Cameron told Yahoo News. “If it’s just people sitting and talking or walking and talking, relatively slow-developing images, it is not necessary.”

For the first time I appreciated the value of sweet action in cinema. The underwater sequences, especially the quick and final chase on the sinking jet ski, have a hyper-real quality that makes me feel like I’m underwater. I did not notice any drastic changes between the standard and HFR sections, and after the first hour I stopped paying attention to the list altogether. It’s a huge improvement over other HFR movies I’ve seen, like The Obi, and the soap opera effects shown on TV, which really bug me.
However, the list was not great. In an opening sequence of a ship approaching Pandora, the whole film slowly pans out, and I am immediately disheartened. I recognized this disease in early 3D presentations and rides like Star Tours, resulting in my eyes seeing something my inner ear could not feel. This time, it lasted for a few seconds and then disappeared after the movement ended, and despite all the crazy action and constant movement, I did not experience anything like that for the rest of the movie.
And I mean constant motion. The pace of the film was broken by some quiet sequences and sometimes felt like a nature documentary, but I still saw movement everywhere. The effects of the hands, panning, sliding and pulling and pushing quickly from the camera, flora and fauna swimming and flying in air and space, and of course the mesmerizing Na’vi and the grace of the cats and simple reflexes – the film never. stop A bit like flowing water.
Talking to Scott later, my first point of comparison was a premium video game – and I mean that as a compliment. Newer gaming and television systems support even higher frame rates, typically 120 frames per second, which make the action smooth on the screen. But play is an active experience, something I have control over. I like to think of Avatar: Way of Water as an immersive ride directed by a skilled director. Cameron gave me ups and downs, depth and captivating visual beauty that overcame my left brain clubbing and story, dialogue and character development that made me feel like a part of an alien world. It’s a full three-plus hours, in a good way.
