Not the first
Sharp have been doing these for years WITHOUT the need for glasses. I saw one back in 2004. Maybe the quality isn't so great but they were still the first. Get your facts right, please.
Acer will enter the record books today by releasing the world’s first 3D-capable laptop. So Register Hardware caught-up with the firm behind the technology – Dynamic Digital Depth – to discover how 3D content will look on Acer’s machine. The 15.6in Acer Aspire 5738DZG 3D laptop has a screen that is coated with a thin 3D film. …
Does anyone know how this works?
I could really use something that can extract 3D information from JPEGS. It would be great to allow me to add focus blur to images to change the depth-of-field after a picture has been taken.
It could also mean people can avoid buying those expensive new fangled 3D cameras (as in a new-fangled version of something that has been around since the 70's)
If you have got rid of the polarising nature of early LCD screens, and apply a per-pixel static polarising filter, then I guess that this isn't too difficult. All you would need to maintain resolution is double either the vertical or horizontal resolution of the screen, and provide a mechanism to address every alternate pixel in each of two virtual display adaptors (or two screens on a dual head adaptor). Registration problems from a distance would not be noticeable. I guess that the technology is up for this.
It would be better still if the polarising filter could be rapidly switched on or off, whereupon you could use the same pixels, and just paint alternate frames (not sure whether LCD's are responsive enough for this).
Would be interested in the software algorithms to analyse 2D images and create 3D projections, though. It must get it wrong sometimes, surely.
We used "flashing stereo" glasses for molecular modelling back in the eighties: the first lot of glasses were quite dangerous - lead tartrate, I think they were, and you needed lots of volts across your forehead (effectively) to get them to work.
Not long after that, we had proper LCD ones - the graphics system (an Evans & Sutherland PS300) would alternate left and right views many times a second, and in the bottom cornier of the screen was a pair of white squares that we blutacked a pair of sensors over: when the left square was lit, the right eye was shaded, and vice versa.
Net result, glorious, ghostly protein molecules tumbling in the air over the keyboard....
Glasses - obviously!
