3D Glasses

[joshwill]

Those of you who got a chance to see Nightmare before Christmas in 3D, do you know if that was the same process they use for the 3D films at the parks?

Id like to use the glasses i paid for when i saw the film for Philharmagic and the others. It would be kinda cool to be wearing your own personal glasses.

Hmmmm, haven't seen that yet! I hope I see it soon!

I saw Nightmare in Theatres! I thought it was great! I imagine that all 3D glasses are made the same way, so if you wanted to bring your own glasses, you could.:wave:

We were told by someone working at the theater that the glasses from Nightmare wouldn't work on the IMAX 3-D. (We saw Nightmare 3-D and Open Season in IMAX 3-D on the same day.) They said that they were different processes. Now I know that the IMAX theater has 2 projectors running at the same time and the digital screen only has one. Let us know if it works when you go.

the result should be the same ... the digital projectors work with a switching polarizer and higher framerate

Though each use electronically controlled polarizing lens, Disney Digital 3D and IMAX 3D use differing frame rates and thus each requires glasses specifically tailored for that given frame rate.

However, if the polarization process is reversed, it could result in a negative polarization which at the same time could create a marginal deflection of the frame rate which would then create a symbiotic response of the retina.:lookaroun

Very very good, I didn't think too many people were familiar with the process in non-celluloid projection systems.

The very cool thing about Digital 3D is that the glasses use circular (think spiral) polarization and therefore the 3D image isn't distorted by movements of the head, even if you tipped your head upside-down, the image would still be in 3D. All of the theme parks use angular polarization, meaning, each lense has an opposing polarization angle of 45 degrees. Expect to see more spiderman type 3D rides using the new Digital 3D technology, even though spiderman does not currently use Digital 3D. It uses an awkward technique called squinching, which changes the polarization angle of the actual film to match the angle at which your vehicle is currently at.

OOOOOOOOOOOOOOH!
So THAT'S how they did it!
We saw NBC3D last weekend, and i was amazed that i could both wear the lenses over my glasses, and tilt my head around with none of the problems i have with the theme park movies. I was wondering what the difference was.

I just want to say that I'm very impressed with the technical know how of you fans. Very impressed!:dazzle: Thanks for the info!

can someone translate that into english?

I know you are, but what am I?!
