P3D Re: Projection problem

In a previous post I mentioned about how, regardless of which
way you put on polaroid glasses, you won't see pseudo 3-D. This
is unlike anaglyph glasses where you would see pseudo one way
and not the other. The reason why is because the designers were
bright enough to orient the polaroid filters at 45 degrees.

If you put uncut 3-D film in a projector and manage to get
the correct spacing between frames, you can preview the film in
3-D, simply by turning the glasses 180 degrees away from you.
Cut and tranposed film will result in pseudo. John Dukes
ingeniously uses this in his Previewer device that is (I think)
still commerically available. The device set's up the correct
spacing for viewing uncut film in a TDC (if I remember correctly).
