How 3D Glasses Saved Britain From Hitler’s Deadly ‘Doodlebugs’

Recently released photographs shown in a BBC documentary ‘Operation Crossbow’ have revealed how 3D glasses like those in modern cinemas helped British intelligence saved the country from Nazi’s deadly missiles.

Hitler’s deadly V-1 and V-2 missiles, known as the doodlebugs, that landed in London in the summer of 1944 were the biggest threat to Britain claiming thousands of lives. Read more…

Sony To Give First Year Post Mortem on PS3 3D Gaming

Per IGN:

Sony Computer Entertainment’s Vice President Mick Hocking will reveal whether it’s a happy first birthday for 3D gaming on PlayStation 3 during a keynote presentation at the Develop Conference in Brighton. Hocking’s address – The Stereoscopic 3D Experience: The First Year of 3D on PlayStation 3 – will take place at the Odeon Brighton cinema in full HD stereoscopic 3D and open the third day of the conference on Thursday 21 July.

Develop delegates will hear about the transition from promoting 3D gaming to actually delivering the experience into people’s homes, as well as tales about what can go wrong with 3D content and a glimpse into the future to see how new technologies may shape the 3D gaming experience in coming years.

MIT: New Approach To Glasses-Free 3D Technology

Researchers at MIT’s Media Lab announced on Wednesday that they have developed a new approach to glasses-free 3D technology.

The team said they could double the battery life of devices like Nintendo’s 3DS portable gaming system without compromising screen brightness or resolution.

The researchers also said that their technique would expand the viewing angle of a 3D screen.

According to Doug Lanman, a postdoc in Associate Professor Ramesh Raskar’s Camera Culture Group at the Media Lab, Nintendo’s 3DS relies on an older technology known as parallax barrier.  This requires two versions of the same image, both of which are sliced into vertical segments and interleaved on a single surface.

The team’s HR3D system uses two layers of liquid-crystal displays.  The top LCD displays a pattern customized to the image beneath it.

This top layer consists of thousands of tiny slits, whose orientations follow the contours of the objects in the image.

The slits are oriented in so many different directions that the 3D illusion is consistent no matter whether the image is upright or rotated 90 degrees.

Lanman said in a statement that if a device like the 3DS used HR3D then its battery life would be longer because the parallax barrier would block less light.

The 3D image would also be consistent no matter the viewing angle.

“The great thing about Ramesh’s group is that they think of things that no one else has thought of and then demonstrate that they can actually be done,” Neil Dodgson, professor of graphics and imaging at the University of Cambridge in England, said in a statement.

“It’s quite a clever idea they’ve got here.”

However, Dodgson said that HR3D is very computationally intensive.

“If you’re saving battery power because you’ve got this extra brightness, but you’re actually using all that battery power to do the computation, then you’re not saving anything,” he says.

Luddites Rejoice! New Glasses Let You Watch 3D Films in 2D

Per Discover:

Eyestrain. Headaches. Nausea. For some people, this is all part of the 3D movie experience. And until now, your choice was to either suffer through 3D; find a cheaper, low-tech theater; or else forgo some new films altogether. But that was before one guy invented 2D Glasses, a pair of specs that converts projected 3D images into 2D (yup, you read that right). It’s touted as a way of preventing eye strain while still enjoying a flick with your 3D-loving friends. Read more…

How 3D TV Works

According to PC World:

If you want to see a 3D image in a 2D plane (on your HDTV), you need a way to show your eyes slightly different images—that’s how you “trick” your brain into perceiving depth. The easiest way to do this is to wear glasses that can help to present a different image to each eye. (Smaller displays, such as the one found on the Nintendo 3DS, don’t need glasses because the display itself is designed to show each eye a slightly different image, but this technology doesn’t work well enough for larger displays quite yet.)

Next For 3D Movies: Better, Brighter Technology for the Screen and For Your Glasses

There is no doubt that 3D movies are here to stay. The people who do such things came to CinemaCon, the annual gathering of that National Association of Theater Owners, attended by exhibitors, studios and manufacturers of movie going accoutrements from seats to snacks, to tell those in attendance what others changes are being brought by 3D.

For example, back in the day, 3D movies were projected on any old screen that happened to be hanging in the theater. Now, however, screens are specialized for exhibiting digital and 3D film. Read more…

3D Technology Could Brighten Solar-Industry Output

With the solar energy industry booming, companies large and small continue to look for ways to squeeze efficiencies out of decades-old technology. So why not 3D technology?

Santa Barbara-based startup Solar3D wants to harness concepts found elsewhere in high tech to increase the capture of more of the sun’s energy hitting solar panels and turning it into electricity.

“Our inspiration comes from fiber optics,” says Solar3D CEO Jim Nelson. “They manage the light to make it do what they want it to do, versus [flat] solar [panels] that just takes it as it comes.” Read more…

Electronics Analysts Give Approval Rating To LG’s New 3D TV Technology

Dubai, UAE. 14 April, 2011 – With the outbreak of a format battle to rival the VHS-Betamax war of the 1970s, the future of 3D television technology is being fought on the one side by Shutter-Glass type screens and on the other, by a new technology dubbed Cinema 3D, developed by LG electronics.

In a March 2011 survey, analysts in Korea have just given LG Electronics a boost in the format battle by scoring their preference for Cinema 3D technology over shutter-glasses (SG) type screens.

“The crucial difference between the two technologies is the way the screen creates and transmits the 3D image – one using a ‘flicker’ type technology with battery-operated shutter-glasses that synchronously ‘shutter’ the image shown to each eye,” said Mr. K. W. Kim, CEO, LG Electronics Middle East and Africa. “The other, LG’s new Cinema 3D technology that allows lighter, cheaper glasses and can be viewed from wider angles and virtually any seating position.”

A comparative test and survey was conducted among analysts from 33 securities firms and the overall result was a 57.1 percent approval rating for Cinema 3D against a 35.7 percent rating for its nearest rival. Analysts marked viewing comfort as the highest rated attribute of LG’s technology finding the ‘flicker’ effect of rival SG technology the aspect most in need of improvement.

iPad 2 Goes 3D And Glasses-Free

3D iPad 2

With 3D HDTVs rising in popularity, many people are intrigued about owning a 3D device, but some just don’t want to pay the extra $150 per pair of 3D glasses. Owners of the iPad 2, however, may be happy to know that glasses-free 3D capabilities may be on the way for the new tablet, thanks to the addition of a front-facing camera in the second generation iPad.

Researchers in France’s Engineering Human-Computer Interaction Research Group have developed a hack for the iPad 2 that they call Head-Coupling Perspective, which can track the position and movements of a person’s head in 3D. But the 3D image the user sees doesn’t actually come out of the screen like most 3D images seem to do. Instead, it stretches back into the screen.

Working in a similar way to the Nintendo 3DS, but reminding us more of the DS game Rittai Kakushi e Attakoreda, it’s basically a 3D representation on a 2D screen that follows you as you move. According to the EHCI site, researches used “off-axis projection to adapt the perspective of the 3D scene.”
