Just found out about this new 3D tablet that works without glasses.
https://www.leiainc.com/lume-pad-2
It's Android and I'm talking with the team there about getting my game on their platform. Might be worth looking into if you have extra money laying around.
What does "glasses free" mean? I didn't see an explanation at that link.
It basically looks like a hologram.
I am very partial to stereo (three-dimensional image). It looks quite attractive. Of course, you can never have too much money, but I would look for the finances for such a device. There are just a few things to be concerned about:
The device is more for entertainment than a full-fledged working device.
And… aren't all these …0,99 annoying? It's clear that this is pure marketing and manipulation? It can't be a reasonable price.
cybereality It basically looks like a hologram.
If it's a hologram, why the face tracking?
And how to manipulate it?
And how can the stereo effect of such close up cameras be achieved? The more I look at it, the more questions I have.
I haven't seen this one, but I say the Acer 3D monitor at GDC and it blew me away. I'll let you know when I get it.

Here, yeah, by the way. 3D monitors were shown at exhibitions while they were still prototypes. And this wonder?
No the Acer is for sale, it came out a few months ago but is hard to find. I had to buy it on eBay.

There's also a Pro version, but I couldn't find it on sale 
Yeah, that's the one from the video.
Tomcat Well this isn't their first device, and I think you got a bit of those statements wrong.
Tomcat Fundraising is very local. Not available in Europe.
It seems like it's licensed by ZTE internationally under a different name. ZTE can't sell in the USA due to regulatory issues (China) it seems.

Tomcat 2560x1600 resolution and 8GB RAM — for stereo this is on the limit.
Most modern Android devices these days allow you to use "Extended RAM", so you could probably easily push this to 12GB, 14GB, or 16GB in Settings. As long as it has that feature, I think that's more than enough.
Tomcat 128GB Storage (+SD the same 128GB) — also very small volume.
I don't think this is correct re: the MicroSD slot. I haven't seen any device locked to a 128GB card if it's using SDXC or a modern standard. It probably supports 2TB expansion.
Tomcat Almost no distinct technical documentation, how it should work — mostly general, vague phrases.
Their old devices (RED Hydrogen One and Lume Pad) used a 4 by 4 view array passively, and could be viewed by multiple people without head-tracking, and could be rotated both in landscape and portrait. This new one seems like it only works for one person at a time with head-tracking, and only works in landscape. The complaint about the old one was that the resolution was pretty low, but the reports about the new one from various sites says it's really sharp, some video reviewers seem to say it's the best 3D they've ever seen, but who knows whether you can trust influencers or not.
Tomcat And… aren't all these …0,99 annoying? It's clear that this is pure marketing and manipulation? It can't be a reasonable price.
Isn't that just the pre-order deposit? Don't really know how else they'd do it, besides just charging the full price up-front. The actual price is $1099 with $100 off if you do the pre-order.
Tomcat If it's a hologram, why the face tracking?
And how to manipulate it?
And how can the stereo effect of such close up cameras be achieved? The more I look at it, the more questions I have.
The original one had all the views I mentioned above. As you moved your head, you got to see different angles of the image. I assume the face-tracking camera does that now instead. You can just touch the screen to manipulate stuff, or use a keyboard/mouse. It's a normal Android tablet in that respect, whether or not the content on-screen is 3D. The first one had an even smaller 3D camera. The 3D was really good for stuff up close, pretty good for stuff at a mid-range distance...and basically had no depth for things that were more than 20 feet away.
Note: most of what I know is based on the original Lume Pad, the new one might be totally different, either better or worse.
NotWaitingFor Thank you for the most detailed answer!

There is only 8GB RAM. Can it take more than the RAM it has?

In theory, yeah, the cards exist. But in practice, not all cards are readable, but only up to a certain amount. Very often in the characteristics of devices do not specify the maximum supported capacity. And, of course, it would be nice to have a larger main memory.
Isn't that just the pre-order deposit?
I mean the price formation itself — can't the price of completely different products magically end with ..99 Why not $1,054.76 or $988.32?
Clearly, "...99" is a marketing manipulation...but people are apparently used to it. It seems that it is no longer a matter of principle.
All in all — the thing is quite interesting. It would be nice to get a feel for it.
And, thank you very much for the link. No stylus, apparently?
cybereality Yeah, that's the one from the video.
I may have missed it, but I didn't find what type of display is used there? I guess if it was OLED, that would have been pointed out.
I don't think it's OLED, or as you said they would say. But the Acer looked very nice, I'm guessing IPS.
There's a video here:
that mentions the tech used for the screen briefly (at around 3:45). It's got a nanotech layer on top of the normal panel. It sounds like it uses that to control the refraction based on the face tracking cameras.
Yeah, I spoke with the product lead the other night. I think I'm going to make an Android game for the tablet (well I had this idea anyway, but it would work in 3D).
Basically there is a back light projection (I assume LED or similar) and this nanotech layer that is able to redirect the direction of the light before it hits the LCD color panel at the sub pixel level.
So instead of the light coming off the screen in all directions (like a normal monitor) it points rays in specific directions (namely to each of your eyes).
This layer is active, so it can project light directions within a small angle (about a 12" box) so it uses eye tracking camera to alter the direction of light. Pretty neat.
I wish they wouldn't do false advertising though (the frog pic). Tilt Five (who I really like, I've got one) do the same, they show pics where the 3d is overflowing out of the screen, which is impossible. Tilt Five's excuse is that's what a Hololens looking at the Tilt Five would see, since some of the software supports both.
I wouldn't mind a Looking Glass lenticular display, it's interesting. But a bit freaky, to get the 3D effect you need to generate 45-100 images which are merged together.
I'd really love to get a Voxon display. It does let the 3D image appear to flow off of the display, it's an actual 3D volumetric area viewable from any direction.
It has a flat panel that rapidly moves up and down over the volume, while a display is projected onto it from below.
The chief scientist at Voxon is (or was, not sure if still there) Ken Silverman. He created the Build engine used in Duke Nuken 3D, Shadow Warrior, Blood, etc.
Sadly the Voxon is $11,000+.
Kojack Sadly the Voxon is $11,000+.
Well, the first models of advanced technology are always expensive.

Something reminds me of the mechanical scanning of the first televisions 
(I could be mistaken in the translation of the term).
cybereality I think I'm going to make an Android game for the tablet
Yeah… Android… I'm not sure that my project can run on a smartphone. I'm more PC oriented and this technology interests me mostly as a monitor technology.
Maybe it makes sense to add the link
in the first post?
I don't know if this is appropriate… but another 3D display:
Sony bumps up size and resolution of immersive glasses-free 3D display
27-inch, 4K
Sony has also widened software development support – as well as its own SDK plus Unity and the Unreal Engine, the new display is compatible with Open GL, DirectX11/DirectX12 and, later this year, Open XR.
Yeah, I saw that video. Looks interesting. I'm getting the Acer monitor tomorrow. I'm hoping I can get it working with Godot on Linux.

I got it. It's crazy.
cybereality I got it. It's crazy.
Sure, the artifacts are visible, for sure, but… WANT!!
Allah and Buddha — bless the creators of Tor, which allows you to open banned addresses! Twitter is blocked in our land.
The artifacts are cause I'm holding the phone with one hand and the tablet with their other, rotating it, and it's also tracking my eyes and updating the screen. It's lucky you can even see anything.
It's pretty clear in real life as long as you don't move your head too fast. You can view images, they have AI 3D conversion for YouTube, etc. it's amazing.
Here I put it on YouTube so it's easier.
cybereality It's gimmicky but still looks amazing! Is it exhausting for the eyes to look at it for prolonged periods of time? I'd probably get vertigo 
I'm used to 3D but it does feel a little weird. Similar to Nintendo 3DS. But it doesn't make you sick like VR.
Also, relevant for game development, they have an app store, but it's basically empty since the thing came out today.
Currently they only have a public Unity SDK, but I'm talking with the team there, I might be able to get a C++ SDK.
Going to concentrate on getting out some small mobile games quick for this thing. Could be a gold rush.
If they give me low level access, I can do a Godot integration, but otherwise I may have to use Unity for this.
cybereality Could be a gold rush.
A "gold rush," there could be if a lot of people got into it. This is a niche product. But it looks very attractive.
Also, relevant for game development, they have an app store
Is it for Android?
Yes, it's an Android tablet. You have full access to the Play Store for normal 2D apps, but all the 3D apps need a special SDK I guess, so it goes through their custom store.
For some reason, I'm having a hard time getting a clear shot of this tablet. Maybe because of the way the screen works. It looks really sharp and vibrant in person.
This is a normal 2D games I downloaded just to check performance. Not quite 60 fps, but it was still smooth and looks good.
Wrote a review on my blog, this thing is sick!!!
