Yes, CES 2011 proves to be the gift that keeps on giving!

Natural View is a technology that takes traditional 2D content, and converts it to multi-view auto-stereoscopic 3D on the fly.

On the fly conversion and multiview screens.... two things that don't go too well today if you have a somewhat healthy "stereoscopic eye". May i ask for your (Neils) personal opinion about it? I'm curious if there's an enhance in experience compared to the old philips wowvx-time.

I wouldn't have much hope for their 2D-3D conversion process, but I guess the 3D to 8 views conversion could possibly work quite well. That would be really great to be able to experience the added depth perception thanks to motion parallax. I'd also like to hear Neil about his feelings about this.

I feel feclempt.

Generating 8 views in 2ms?!?! I don't think it can be done.

Uh Neil, what does "feclempt" mean ? Can't you elaborate a little bit more ?

Why so ? If Samsung is able to generate 8 intermediate views (240Hz/24Hz - 2) in realtime by interpolation for their UN55C8000 TV, I don't see why this company couldn't do it.

Basically this is about 2d+depth, nothing more. The conversonalgorithm makes a depthmap which then is applied 8 times to the 2d-image. Or even simplier with a small altering only one render is needed to generate all 8 views in one blow without the need of applying the depthmap to each and every view.
However: Multiview displays=low resolution (unless someone find a real brilliant solution...

). It uses 2d+depth algorithm so the display can't even take a "true" stereoscopic signal and display as is without conversion (it's theoretically possible to separate the two views like in a stereoscopic lenticaular device thus needing no conversion but then only two views are used).

Multiview lenticular/parallax/whatever displays have some plusses though: Glassesfree. The multiple views makes viewing more natural since headmovements to some degree is compensated. While you'll loose impression of depth when moving closer to the screen while using "standard" stereoscopy, a multiview display will maintain the imagined image since views shifts when you move the head, even depthwise. This will make the image appear more "holographic" than "standard" stereoscopy.
"Standard" sterescopy maintains the images which during headmovements makes the brain think that the image/scene itself moves.

However i have no hope for this technology though. At least not yet. Still curious about other feelings than "feclempt"!

Cheers!

I think neil is said that in sweedish or german like those fellas in the video. Thats real cool that they are using hardware encoding or is it software? Nevertheless they would need to get a kernal codec microchip that does the 7gbps encoding in the tv. Would be nice to hook in a coaxial low def cable signal and get an autostereoscopic 9 view experience.

And the whole reason it cost so much money and that autostereo and high def stereo modes are failing is cause Intel and Amd are not making those new Photonic Microprossesors along with data connections to the tv with fiber optic cords cause the raw materials are getting ruled by the chineese government and somehow everyone thinks chineese or japaneese made electronics are the best, but in actual fact those places are milking the cow on old outsources tech like copper wire and expensive overrated quality 3d effects. It cost 40 million to make a 3d animation film, sounds like everyone is happy with the money spent vs money coming in. As long as theres something worth it in stereo3d in the next 10 years I'll be happy. Just hope it comes out alot sooner. Could be magical**

Talk amongst yourselves...

You've got a point there. I guess I will reserve judgment until I can see the thing with my own eyes.

It's a little bit more interesting than 2D + depth I'd say since they've access to real 3D information (a stereoscopic couple). It could probably be called 3D + depth since they also have access to the occluded informations in each view. I think that would produce better results than a 2D + depth approach if they're able to correctly build a depth map from the two images and use the information given by occluded pixels in each view.

Likay wrote:However: Multiview displays=low resolution (unless someone find a real brilliant solution... ).

The brilliant solution has already been found, you just need to have a display with a really big resolution like in the 56" Philips 3D TV (3840×2160). Better resolutions are still needed, but I guess technology will allow this in the future.

Considering what can be achieved with printed images and lenticular sheets, I guess it's only a matter of time before we can experiment this on TV sets.
