Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

In research and design applications it's often one or two people at a work station. Simple double image red/green 3D or even vertical lenticular is possible. Sun had a system I saw demoed in the 90s for looking at and rotating molecule simulations in 3D.

I did some large (1.5m high) lenticulars a few years ago for a cruise ship that contained 8 separate static images. As the passengers walked past the image changed. No glasses needed. Lenticulars have a quite wide viewing angle, and I would guess that putting up two images (the stereo pair) on a lenticular screen is possible. Digital images are stable horizontally - but the vertical lenticular lens sheet would have to be almost directly on the surface of the screen image.

I meant putting two moving images up behind a lenticular screen. The images are vertically sliced to fit behind the lenses. That could be done by image processing.

Indeed; the advertising display technology folks are wild about this. It catches the eye of people walking by, it doesn't have to be perfect to get the message across, and it grabs people from the walkways.

Here's last week's latest and greatest from Display Daily on an Autostereoscopic Cinema Display Proposal.

So, what you think? A few dozen straight lines, this Dremel Tool and my friend's iPad screen might lead to the next coolest thing?

Very interesting...

The guy I worked with on the lenticulars was David Burder in the UK - something of a 3D genius living in a leafy suburban street and doing 3D in his (large) garden shed. A true British eccentric - but he knows his stuff.

He was also involved in the Nimslo still camera concept.

Oh my. I have seen the David Burder site before. Now I have some back story.

So, you think I should be asking him about my iPad etching?  ;-)

Personally, I don't have a problem wearing glasses to watch 3D, as long as they have a comfortable nose piece and block out extraneous light. And these are now available...even clip-ons are available.

So the concept of going through all this trouble for TV 3D without glasses is madness to me. Skip all that, handle some other real problems with 3D TV (such as children not having 6.4cm eye spacing and the different sitting distances for TV making the big screen and TV experience different) and put all the future efforts into hologram technology.

There is a piece that I am working into the next series piece. Normally I blow by all the doom and gloom, eyeballs will be bleeding stuff. But I have attended presentations by Dr. Marty Banks in which he commented on this issue of TV 3D "problems". (Of course, just because I attended his presentation doesn't mean he is validated...but,) I don't think that he is someone who should be blown off.
