A 3D Presentation in Space-Vision

Legacy - The Bubble marked the introduction of the economical Space-Vision 3-D system. Unlike the two-camera, two-projector systems used to make and show the 3-D feature films of the 1950s, Space-Vision used a single ordinary movie camera with an external optical attachment that allowed it to simultaneously photograph the left-eye and right-eye views stacked in an “over-and-under” configuration on a single frame of film.

Because each image was only half the standard height, this resulted in a widescreen aspect ratio with roughly the same proportions as CinemaScope. A special attachment on the projector allowed the two images to be projected through oppositely-oriented polarizing filters and superimposed on a screen provided with a special non-depolarizing surface.

As with the feature-length 3-D films of the 1950s, the audience had to wear Polaroid-type 3-D glasses so that each eye would see only the image intended for it. Space-Vision was used for Andy Warhol’s Frankenstein (1974), the only widely shown first-run polarized 3-D film of the 1970s.

Functionally identical over-and-under systems, branded with various names, were used for most of the films made during a revival of 3-D that began with the release of Comin' at Ya! in 1981 - Notes by Wikipedia
