A question about 3d glasses?

I was wondering, if there was a 3d film and you had a video camera, you put the 3d glasses infront of the lense. Would the result be 3d when played back on a tv?

Btw this is not for intended copying just curious.

No. It takes two eyes to see a 3D effect. What the 3D glasses do is to make that each eye sees a slightly different image. Whether it is by polarizing the light entering each eye at a different angle, or by filtering through the red and blue lenses, the combind images are “blended” in the brain as a 3D image.

No it would not work. That is because in a 3d movie they project two movies onto the screen at the same time giving you double images of everything. The one set of images have one light wave and the other set of images have a different light wave. Then the glasses will block the one light wave but let the other one in so your one eye only gets one of the double images, the other eye gets the other set of images.
Your video camera as it recorded would not be able to split up the double images correctly for playback. Also your tv can not do double light waves. When it was made it was only made so all the pixels could do brightness and color. That is why when they sell 3d dvds it uses the 3d with the red and blue glasses. Now if you tried to video tape that 3d format it would more likely work because your camera is made to pick up the colors of the red and blue double images.
All projectors and dvds and video sources and televisions have to be specially made so 3d can be viewed by the person watching it, because of all the double images and then having to get those double images to the correct eye. A normal television or projector or camera just can’t do it.
Also the 3d cameras they use to make 3d movies have two lenses about two inches apart, not one. So it films two movies at the same time.
