When I worked with it, it was not as strong. If you thought today's 3d was conservative, the screen was even more so. You could crank it up, but do it too far and you would get nauseous. So given it ran in 3d all the time, it was dialled down so practically everyone could walk by without getting sick. Unlike a normal 3dtv which was only displaying it with glasses and a blurry mess without, or 2d, the display was always on 3d, like a portal to another world.

It worked with standard stereoscopic sources over HDMI - frame packing format preferred, but top/bottom or side by side was workable too. There was a built in 2d to 3d converter that worked surprisingly well, though it was even more subtle. You knew it was showing depth, but it wasn't trying to apply gobs of it to make it seem ridiculous.

Of course, I didn't have a 3dtv to compare it with - there was no business case to get one, so work never got one.

When I needed to demo it, I always used Pacific Rim for my 3d content demos, while I usually used either Shooter or Now You See Me for the 2d to 3d real time conversion demos. Landscapes seemed to work well, because the natural perspective augmented the effect.

Alas, it's been a few years since I worked with it. And by that time, 3dtvs were becoming extinct. I will report that when I went to watch a 3d movie I wondered what the glasses were for - I had gotten so used to glasses free 3d that I forgot glasses were still the norm.

Yeah, that's the way I am with my phone. It's just 3D, no glasses. In fact I probably see more 3D on my phone right now than anything else. I think the Leia screen is pretty good, but not on the level of glasses 3D. I wonder if there's something different about Ultra D, different meaning not as convincing. Leia, I don't see any of this waviness talked about. But the image does readjust for different viewing angles as you move the device or your angle to it and there is a slight shimmer if you're not in the correct viewing angle. Straight on viewing is best of course and it's a pretty clear image with a decent amount of 3D range, but it can show crosstalk, probably more than most glasses 3D options before.

I can see these two going head to head on the glasses-free 3D market. The Leia screen is sharp all the way through unless the image has some intentional shallow depth in the shot. But there's no word on when larger screens are coming. Only news has been that RED CEO pulled the plug on the Hydrogen program. But the screen supplier Leia is still making products, fortunately. I really can't wait to see what a larger format would offer. I have a feeling it's a step ahead of Ultra D, but I haven't seen Ultra D to compare plus the size difference.

The waviness happens when you're really close to the screen - they're a result of the multiview optical film. Once you're in the sweet spot it's gone. The technology allows for a 179 degree viewing angle screen - while 3d shows up in the central 120 degrees, the people on the edge get a 2d image. Go too far back and the image degenerates back to 2d as the multiview is too spread out.

But at no point is the image unwatchable to anyone. And it's a wide enough sweet spot so you can have a small crowd of people watching. Though a few times I had to gather the group together because they spread out for the demos and wonder why they can't see the 3d.

Looking Glass revealed its latest holographic display – the Looking Glass 8K Immersive Display.

For those unfamiliar, Looking Glass isn’t traditional AR or VR but provides a method of viewing 3D content without the need for head-worn gear.

The newest display is measured at 32 inches and provides multiple perspectives for 3D content which can be viewed by multiple people in the room without any additional headsets or head tracking. Looking Glass displays typically generate “45 distinct and simultaneous perspectives of three-dimensional content” with the new 8K version said to offer “33.2 million pixels…with over a billion-count color gamut at 60 Hz.”

In a world of impossibly thin flat panels, I'm not sure where a volumetric product like this could exist in the market. It might have uses for 3D modeling, that appears to be their target. But for displaying traditional stereoscopic 3D content that we view, not likely to become mainstream due to its shoe-box shape and limited viewing angles. These are better for single-use purpose, developing or viewing.

And I have to point out the obvious fact, it's a step in the wrong direction. I would rather slap on a pair of glasses than view something in a box.

World’s first 8K 3D display for the creator market at CES 2020

In collaboration with Microsoft and Ultraleap, Dimenco demonstrates the world’s first interactive 8K 3D display at CES 2020. Enabling creators to build 3D designs in a fully spatial environment, without the need of any headwear or other wearables, delivering a dramatic improvement in possibilities and overall immersive productivity.

LAS VEGAS -- January 2, 2020 – Dimenco, leading in light field display technology, introduced the concept of Simulated Reality (SR) technology one year ago. Today, the global launch of its Simulated Reality Development kit comes full circle at the 2020 Consumer Electronics Show (CES) in Las Vegas. This 32” 8K SR Devkit is the ultimate spatial desktop machine available for all creators. As shipment started last November, the developer, designer and engineering market prove to be among the first to adopt the technology.

Commitment to creative innovation is never over
The creator market has always been on the forefront of incorporating the latest innovations. After decades of creating 3D designs on 2D monitors it no longer makes sense. As display technology has immensely evolved, it can now clearly show to the user dimensions and all critical details of their 3D models that regular 2D displays just can’t capture. At any angle in a fully natural way without the need of any headwear or wearables. Which is an incredible benefit.

The display comes with a software development kit (SDK) that supports the top game engines in the market today. Developers can seamlessly create SR applications using the Unreal engine and the specially developed Unity Editor. Plus, it enables developers to easily port their existing 3D content.

In collaboration with Microsoft and Ultraleap
Dimenco is collaborating with Microsoft, who will feature the new immersive spatial display at their CES Experience Center and has partnered with Ultraleap and certified their Leapmotion sensor for embedded SR hand tracking. Also from Ultraleap, is mid-air haptic feedback as an add-on. The Dimenco/Ultraleap partnership produces wearable-free, 3D graphics that users can interact with and feel with their bare hands, creating a new form of interaction with digital media.

Steve Cliffe, CEO at Ultraleap spoke of the partnership: “Adding the sense of touch to digital content makes it come to life. Experiences are much more immersive and engaging. We are therefore very excited to partner with Dimenco on the SR devkit to create the most natural interactive platform from which developers can create immersive and magical content.”

First Simulated Reality laptop by MSI

The SR Devkit is just the first step. Ultimately, with Dimenco's proprietary spatial technology, makers of monitors, laptops, tablets, phones and other devices can incorporate SR visualization capability into their product lines and the first consumer products are expected in early 2021. Laptop manufacturer MSI will demonstrate a glimpse into of the future with the first “Simulated Reality” laptop which presents fully immersive 3D objects that can be interacted with naturally in a virtual environment, without wearables, ready to be utilized in multiple industries such as design, architecture and medical. SR’s unique multi-sensory combination represents the first steps towards the future of human computer interaction.

Maarten Tobias, CEO of Dimenco, said: “While the market for immersive content is growing around the world, wearable headsets, glasses and controllers needed for virtual and augmented reality don't provide the optimal and most natural experience which is hindering growth and adoption. We are dedicated to creating the interactive platform of the future – Our vision is Simulated Reality. Realism, social interactivity, immersion and AI can all be achieved through SR experiences, and we are enabling developers to start creating for SR now with our devkit.”

During CES Dimenco will showcase its newly developed Unity Editor and the SR Model Viewer which demonstrate compatibility with existing off-the-shelve 3D tools. Dimenco is working with select software companies to expand the SR ecosystem and has several significant updates scheduled for 2020.

While an 8K 3D glassless display sounds like a space-age improvement, it's probably still a lenticular display, although the current displays have a wider viewing space. They could be using a parallax barrier crystal overlay, but the barriers would have to be so small that the image would probably be a fuzzy warped mess. Ultraleap's specialty appears to be interactive AR and VR technology--the similar tech used by Oculus for their headsets--displays are just vehicles for the underlying tech. The lenticular strips would have to be micro-sized to handle the 8K pixels, so my guess, they are lenticular masks used in 2K to 4K glassless screens. In that case you aren't getting anything more than some additional sharpness. If the lenticular strips are too small, it would cause eye confusion--my guess.

I'm not trying to dis the technology, just that there are some limits that haven't been overcome yet with glassless tech.

This is an old (2011) explanation of glassless tech. I doubt much has changed other than refinement of parallax and lenticular tech.

Dimenco clear view lenticular lens – 32” 8K 3D panel...Hah, I missed that when I looked it up--thanks.

It's interesting to note that many 24" to 32" 1080p monitors were simply made out of 4K screens cut into 4 1080p screens. It's one thing to make an 80" 8k screen, which already has very, very small pixels versus a 32" screen. I'm almost not buying it can be done. I'm looking at the pixels on my 1080p 28" screen and can't imagine how they could possibly by 4 times smaller...well we will see...

They just didn't cut it into tablet screens... The dpi is similar.

As of March 2020 it looks like Stream has run out of steam! Promises, promises -- nothing but promises.

I think Leia have a better chance at glasses-free 3D TV. But it's edge-lit LED tech so there's limitations.
