What's the Holdup With 3-D Monitors?

Stereo vision should be easy with LCD monitors. Just polarize every
other pixel one way and the remaining half 90 degrees.

If the orientation of each pixel could be changed back and forth
quickly enough then both images could come from the same set of
pixels.

It should also be easy to make stereo compatible with mono vision, if
only by just giving them one image.

In addition to the large video market you spend 75% of your time on
Sketchup changing views to "see" the thing in "3D."

The patents of inventions on 3D monitors seem to be making it more
complicated than what it needs to be.

Yer stooopid.

Take a pair of movie 3-D glasses, walk into the bathroom, look into a
mirror, and close one eye. Look into the transparent lens and the eye
behind it.

Why do you think sci.logic readers have any interest in polarized
lenses?

All the adverse health effects may put a damper on widespread adoption.

Transparent lens?

It was assumed responders to the OP would be intelligent enough to
figger out each lens would be polarized to each image's orientation.

DO THe EXPERIMENT, JACKASS. You don't know shit about polarization.
Observation says you don't know shit about polarization. The universe
says you don't know shit about polarization.

I've been told by someone that 3d tv has already been developed where
you do not need glasses and you can watch it from quite wide angles as
well.

That's basically done : a lot of samsung LCD monitors are already
"stereo compatible" and use this polarization fact. It's not even
advertised.
I'm not sure though what is the pattern of pixels and what polarization
is used (vertical/horizontal, diagonals, circular...).

And to answer Giga2, there are indeed passive 3d monitors. Still
expensive and not very high resolution though.

Nah, the place is littered with 'em already.

But cereally, this is off-topic for sci.logic. Could y'all
remove sci.logic from the list of ng's, as I have?

Thanx.

Not that I personally want it for anything besides CAD but it seems
like the kind of thing that would really be a hot seller.

I have seen various versions of such glasses. Various 3-D exhibition
systems can differ from one another. Looking at a METALLIC mirror can be
surprising results. For example, light reaching the eye and getting
scattered to the mirror will have a 50% loss of intensity loss with an
ideal Polarioid linear polarizer. Ideally, after reflection from the
mirror will not change the polarization state, and there will no
additional loss in the Polaroid on the way back irrespective of the
polarizer orientation.

If you do want to see a real effect, take a polarizer sheet and place it
in front of a cube corner. Rotate the polarizer and look. Use TIR cube
corners and silvered corners and compare. Do the same with a porro prism.

Al, predict what you will see before doing the experiment.
