Does a communal "shutter based 3d" theater exist

[tripletopper]

I believe 3d effects are technically better on a shutter 3d vs a polar 3d.

In polar 3d I accidentally tilt my head, get double exposure, and get a "confused" 3d picture.

My mom does that and she gets 3d headaches.

Now that most companies are forgoing the 3D Blu Ray and 3d Streams, i would like to know if there are shutter 3d communal theaters around northeast Ohio.


If there is one, I'd like to go.

But more likely, I pointed out to the absirdity of handong out $50 powered glasses and communally sharing them in the post Covid-19 world.

I understand the economics of a communal shutter theater doesn't work. (Or if it does, it's unicorn rare and just set up as a tech experinent.)

Someone prove me worng and show me a shutter 3d, (or an alternate 3d that doesn't have the problems of polar 3d.). It's the difference between a good show and a headache for my mom.

If you find yourself accidentally tilting your head when watching 3D, perhaps you should invest in a neck brace...

The possible problem must have been watching in IMAX 3D with linear polarized and is thinking that all 3D polarized are the same. As with circular there isn't the same issue and is much better compared with linear, but linear makes each picture for each eye clear as the vertical and horizontal don't mix.

As I have circular polarized tech and I never got those issues and I can say that it can be as good as linear that I watch on IMAX 3D cinema rooms.

I know I don't get double exposures on a shutter based 3d, and most of my 3d problems come from double exposures. I dont understand how "circular polar" prevents accidental double exposures?

I can explain how shutter works. I can explain how perpendicular polarizing works. I know how perpendicular polarizing fails, by tilting heads.
I know how shutter 3d fails, by large, unequal ping times between tvs.

I can't tell you if I was in circular or perpendicular polarized theater, but i know whatever polar filter was in place was defeated and had double exposures. Tell me how to cause a circular polar double exposure, and I'll tell you if i was in a circular polar theater or not.

By the way, the lack of shutter based 3d communal theaters in the responses show me that I'm right. That the only reasons theaters don't use polar is because of obscene cost in a communal setting. But that shutter 3d is the technically superior tech, but doesn't scale down cost when group viewed. Exactly like Headphones are for sound.

As with linear polarization the lenses must be aligned, one ( - ) and the other ( | ), if you tilt the head the lenses will be ( \ ) and ( / ) basically, which will be misaligned with the projection frequency.

With circular polarization that issue isn't as much stricted. One of the LG ads used to bring this as a feature: that people could watch 3D movies laying on the side. It was advertising exaggeration(as most advertises are) but circular polarization allows much more tilting than linear.

Over the internet and some videos I've watched some cinema rooms that had 3D active glasses and some others that had 3D headsets and all had cables to power them up which imo would make the 3D experience less confortable compared with passive tech.

There are also clip-on glasses(circular and linear versions) for those who wear prescription glasses so that the regular passive glasses won't become an inconvenience. With shutter glasses that basically won't be possible unless you get some contact lenses or really wide and heavy glasses for old 3D TVs. With new ones the active glasses are designed to be put over the prescription ones. The main problem with shutter glasses will always be power to make them play.

So when you say circular, do you mean angular like slices of pizza, or circumfrencial, like rings on a bullseye?

Also I heard there was motion involved in circular 3d. If it moves, is that a polar shutter that universally syncs on and off alternate frames within a communal setting? If so, then circular oolar is kind of a hybrid between perpendicular filters, and timing based filters.

Reald 3D uses circular polarized, while IMAX 3D uses linear one.

There are threads in the 3D forum relative about circular and linear polarization as I don't know much how to explain about it technically.

EDIT: Drag the lint to a new tab because the forum isn't allowing to open it normally.
