IMAX 3D technology is the most advanced 3D film technology in the world and is based on human vision. When you look at an object, each of your eyes sees a slightly different view. Through a process called "stereopsis" your brain brings the two views together into a single three dimensional image. The IMAX 3D projector uses Rolling Loop technology to run two separate rolls of film simultaneously past twin projection lenses. To enable the 3D effect, the lenses are carefully aligned to project both left and right eye views onto the giant screen. To see images in 3D, the audience wears either polarized glasses or a headset that includes electronic liquid-crystal shutter (E3D) glasses. While they have different technologies, both types of 3D glasses work with the IMAX 3D projector to provide stunning 3D images. Blockbuster IMAX Theater audiences wear E3D glasses. Two sets of shutters within the 3D projector switch back and forth at 96 times per second, to project alternate left and right eye images on the screen. During the presentation, E3D glasses sense a signal from the projector. In response to this signal, the left and right eye shutters in the glasses alternately open and close in conjunction with the projector shutters to make sure each eye sees the appropriate image, ultimately creating the 3D effect.
上面提到的3D眼镜要比我们带的先进……:cry:

IMAX and IMAX 3D giant flat screens soar up to eight stories high and are designed to encompass your peripheral vision. These screens are painted silver to maximize the amount o***ht reflected back to the audience. Half the size of a football field and large enough to show a whale life-size, IMAX screens fully immerse you in the scene. 银幕比较
