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 o…

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.

It's pretty sad that such an aesthetic piece of technology is completely ruined by that companys content.

the pursuit of aesthetics has always been bankrolled by commercial dick measuring contests of one form or another. the fact that we can convince our corporate overlords to continue financing unnecessary objects is one of the few things that keeps me hopeful for the future.

Very very cool! Also very very pixelated appearence because the sharp edges to each unit. /me mulls patenting the same kind of thing but by stitching together small cheap flexible LCD screens brought in bulk from Alibaba...

The pixelation is a result of viewing it a distance closer than the distance at which the image was designed to be viewed. At a microscopic level, a fine art photograph will show grain, an inkjet print will show ink dots, and a computer monitor will appear as individual pixels.

The video is shot in close and tangentially in order to show how it works.

By "pixelated appearence" I mean the blockiness caused by seeing the black sides of each block when its a different height. The display is a bit like a minecraft map with the colouring only on one face of each cube.

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'.

It's a very neat effect, but I think his point was that it's not 3D rendering, so from that aspect it's not particularly interesting.

It's sort of like going to a play and then saying you just watched a 3D movie.

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).

I think eliminating the black sides would actually make the 3D effect far less visible.
