IMAX vs 3D?

Question

What is the essential difference b/w IMAX and 3D?
Thanks!

Answer 1

IMAX is a screen format - it's a screen that bigger than your standard movie screen. Therefore, the film that's projected needs to be bigger as well - for example, most IMAX films are on a 70mm print vs. 35mm size for standard movie theaters.
An IMAX movie can also be a 3-D movie. But a 3-D movie isn't necessarily an IMAX movie.
What most 3-D movies do is create a double negative - where the same scene is layered over itself separating some of the colors. If you watched the 3-D movie without glasses, you could see that. The glasses help trick your brain into thinking you're watching something that is 3-dimensional.
You need special glasses to watch 3-D - you don't for IMAX.
hope this helps.

Answer 2

All movies projected in the IMAX format use film that is wider than the movie film used in most commercial movie projections. Each individual movie frame has more than double the surface area of the film in regular projections and the film goes through the projector faster in IMAX. As a result, it is possible to project sharp flicker free movies on very large screens using the IMAX system. Some but not all IMAX movies are also projected in 3D. - In 3D IMAX, two frames are projected on the screen at the same time - one for each eye. (The frames are photographed from slightly different points of view like our eyes.) - The light used to project the 3D IMAX film frames is polarized - in a different dirrection for the left and right frames and the audience wears polarized glasses, so that each eye sees only the proper frame. 3D movies have also been made that don't use the IMAX large film format. - Some IMAX theaters have curved screens on the inside of a dome. - These theaters don't project in 3D. The IMAX theaters that can project in 3D have large flat screens - The screen material on these kinds of screens is silver -gray colored and made of a material that will not depolarize the light from the projector.

Well 3D is in...well 3D...

IMAX is all about the type of screen, where as with 3D you gotta wear glasses to see stuff come out of the screen
