Several glasses for several kinds of stereographic projection.

[right top and bottom] The above methods often uses only one picture or projection source. For the projection with polarized light you have two projektion sources with polarization filters (horizontal and vertical polarization of light). Carying the glasses with polarization filters each eye can recognize only the film/picture of one of the two projection sources, for example in IMAX cinemas. Effect: colour film/picture.

The actual techniques with single projection and high frequence of projection shows alternately images for the left and the right eye and in the special glasses synchron the view of the other eye was closed.
