Light Field Labs has raised an additional US $28 million in funding to develop and produce free air holographic display technology. They are said to have a working prototype now and the additional funding will enable them to scale up to an actual product.
“The aim is to create holographic objects that appear to be three dimensional and float in space without head-mounted gear such as augmented reality or virtual reality goggles.”

The principle people behind the technology had developed the Lytro camera technology. As best I can tell, it may be similar to a digital implementation of a conventional, analog, film-based hologram. In the original hologram technology, you look at a flat image that is, basically, like a window pane. As you move to the left or right, you see the true 3D image visible from that point in space. In the laser-based hologram, the window pane is a film that has recorded light interference patterns.
From the description down the page, here, my interpretation is they have created a currently small window pane that is replicating the light interference hologram concept, but in the digital domain. Obviously, it takes a tremendous amount of computational horsepower and for video, high bandwidth, both of which are becoming available as tech advances.
I presume, also, that this technology can be used to project objects in front of the viewing plane, as is done in stereoscopic 3D. In other words, actors or objects can be appear to be between you and the viewing screen – or behind the screen.
This tech creates true 3D that does not require glasses for viewing.

And while “3D TV” is mostly gone at present, 3D video projectors are very common. Most video projectors support 3D because it is very inexpensive to add 3D to a projection system while it was expensive to put the tech into flat panel TVs.
If you are looking for 3D viewing options at home, 3D projectors are a good option. Another option is 3D computer monitors, which are used in gaming and engineering and other visualization applications.
You’re not seeing things — that photo in your Facebook newsfeed is 3D. Launching today, 3D Facebook Photos use the depth maps from dual-lens smartphones to add dimension to an image as you move your phone. The effect is an image that pops as you scroll, without any specialty gear (unless you want to use your Oculus).

It’s a more modern version of the 3D “wiggle” method made popular, originally, as self playing GIF files that “wiggled” back and forth between the left eye and right eye images.
3D image capture for this new feature works only on selected iPhone models having dual cameras. Facebook says other phones, presumably Android-based, will be added in the future.
This is a very nice set up – its a Daydream VR viewer but it can also be used to shoot VR 3D.
The “nauseous” problem this reviewer experienced is because he had no understanding 3D shooting.
“Tempted by the small size of the Mirage, I had often treated it like a point-and-shoot camera, and recorded quick and short clips everywhere, sometimes even while walking around. Wearing a headset, most of these clips were dizzying and uncomfortable. What’s more, the 3D effect was often barely noticeable, especially when filming anything further away.”
He liked the 3D stills but found that his 3D video was sickening. That’s because he shot numerous short clips and did not understand the concept of a 3D viewing box or the viewing plane. Consequently, he is almost certainly pushing the viewing plane forward and backward very rapidly, causing eye strain and ill feelings. That’s his problem, not the device’s problem.
In fact, I am thinking of buying one of these soon.

Great to see a resurgence of 3D, now in the VR space:
Google introduced its new VR180 creator to help VR camera owners shoot 3D videos and immersive photos using affordable hardware.The tool allows anyone to create and edit VR and 3D content thanks to the simple user interface and beginner-friendly tools.

Since it uses an LED screen instead of a projection screen, it is able to display bright 3D imagery, unlike the dimmer view of projection systems.

Facebook’s concept of 3D is objects and characters modeled as 3D graphics. You can drag the objects around to give a sense of looking at them in 3D – but these are not stereoscopic 3D features.
