What is 3D, as in movies shown in 3D?
I read somewhere that it won’t be long until we can buy television sets that ‘handle 3D’. I don’t get it – I thought 3D as in movies where you need special glasses, aren’t ‘real’ 3D, but more likely something that fools the brain to see the image in a specific way. Isn’t it about colours or something that combined with special coloured glasses conjures a ‘3D effect’? How would that work on TV? Would it be a TV that shows the 3D effect without the need of glasses? Or how would it work?

The scene is shot with two cameras linked together and separated by approximately the distance between your eyes. Then when it is played back, special glass (some polarized, some battery operated with very fast shutters) sent the appropriate image to each eye, tricking your brain into thinking it is seeing stereoscopically.
But this doesn’t require any certain equipment or anything, like special silver screens or projectors, right? The “magic” appears only in our eyes?
Both the television and the goggles have to be designed purposefully for 3D, which is why it is not yet available in homes.
I’ve heard there’s going to be 3-d that works without goggles soon. I’ve seen a tv that works without goggles (pretty cool), so I know that’s coming in a few years. I suppose the movie version would just be one of those giant tvs that does 3-d. No goggles needed. Kind of blow your mind, eh? Our children’s children will never know anything else. Our children will remember a time without it, just as people my age remember a time without personal computers, cell phones and a whole bunch of other stuff.
I remember have seen an effect like that, in Chile in the 90’s. A tv station did it for a few months only, they mainly showed landscapes and used several shots of trees to help notice the effect; i remember you can only see it with special lenses, but the truth is that with any broken sunglasses that holds only one eye you can see the effect. I remember that the “3d effect” was a little cartonish, even when it all was real images without any cgi, it looked like those popup child books, flat scraps of paper passing in fron of your eyes. lovely memories, though. I wonder how they did it.
