This is a cool effect but it looks like it's mechanical: the screen is split into tiny squares which can slide in and out independently. It's not 3D, it's literally tiny screens moving along the z-axis. The technology behind this is probably quite interesting as the movement has to sync up with the video but I can't watch this without wondering how long it will take for some of the tiny screens to get stuck because of a failed actuator. It's more of a clever hack of 2D technology than an actual advancement in 3D technology like the title might lead someone to believe.

Here's a post with better detail, videos of testing the system, etc. It's pretty much what you described. https://hackaday.com/2017/09/02/coca-colas-new-3d-times-square-sign-invokes-inceptionism/ https://hackaday.com/2017/09/02/coca-colas-new-3d-times-squa...

  I'd propose replacing the original link with this one, since there's information about how this display was put together, in addition to a link to the posted video.

> This is a cool effect but it looks like it's mechanical Well, yes, it is mechanical. While I agree with you that this isn't what you would normally class as '3D' it still has a z-axis component; so perhaps it qualifies for 2.5D? Nonetheless, I haven't seen mainstream advertising done like this before and the applications of this (more creative visual / mechanical syncs) are really exciting.

  It is fun to watch, but its really just the uniqueness that makes it special. I personally dont see this getting wide spread use.

    It's just like any other tech demo. The uniqueness factor is all its got going for it now... but to take the next step this technique must inspire someone to use it and create additional value beyond the uniqueness. The next step is now more likely because millions of people will see what is possible and be inspired to create. Similar to what is going on with VR Gaming headsets like Oculus right now.

It's literally real 3D. Do you think only pseudo-3D-in-2D is real 3D, while actual real 3D is just a 2D hack? It's ridiculous.

  If one dimension is limited compared to others, it makes sense to call it psudeo 3d, because all planes are not fully realized. But it is still clearly invoking a 3rd dimension, maybe a 4th if you consider movement in time. I still call it just shy of '3D'.

    My car is 3D but it's only ever car-shaped.

      Yes, but can it be segmented in open regions which are homeo/diffeomorphic to subsets of the R²? (Canonical example: the Earth is a three-dimensional object, but looks 2D locally (at a neighborhood of any given point).

    Offtopic, but why is 'pseudo' almost always misspelled even on HN?
    - pluma 9y ago
      Because in English the way it's spelled seems entirely orthogonal to its pronunciation. "pseudo" basically sounds like "sudo". Compare to German where the way it's spelled is exactly how you'd spell it if you first heard it (and speak German). We don't drop the "p" and we pronounce "eu" as a diphthong as in other Germans words (sounding like "oi" in English). As a German this is why I almost never misspell it in English. It looks the same as in German and is a loanword in both languages, so I tend to sound it out the German way even when thinking in English.

Something always fails. Was curious about the details, though. Actuators from the linked Patent: - F12-BC (W-Robit, Taiwan) - PAC-UGT040D (PBC Linear, Roscoe, Ill.) Motors and servos: - BCH U04 (Schneider Electric, Palatine, Ill.) - LXM23A servo system (Schneider) - Modicon M256 Logic controller (Schneider) - SM23165DT (Moog Animatics, Santa Clara, Calif.) That last motor is a NEMA 23 stepper and commonly used in 3D printers. I remember tweaking the current levels on it with a temperature gun until it was just at 40 C. These particular ones are rated for 85 C and have a high mean time between failure - over 20k hours of continuous operation. At lower (more normal) operation temperatures they can last 10-20 years. Of course, there are always exceptions and lots can go wrong (that random failure, bird gets trapped in the mechanism?), but looks like they picked decent components.

To increase the 3D resolution, all they have to do is make the pixels smaller (1 screen = 1 pixel).
