Oakley 3D Gascan glasses revealed

A couple of months back we mentioned that Oakley would be releasing 3D glasses before the year ends. And just recently, they officially announced these Oakley 3D Gascan glasses that you can use with 3D moviehouses utilizing RealD technology.

With this pair, you no longer have to settle on using dirty 3D glasses used by hundreds of moviegoers already. You simply have to get your own pair of Oakley 3D Gascan and use it instead of the cheap, standard glasses usually being offered in theaters.

A pair of Oakley 3D Gascan glasses is priced at $120. Available in either white or black.

NTT Docomo 3D Display System

Displays used in mobile phones, handheld games, and other mobile devices have shown remarkable progress as resolution has become sharper and clearer with each passing year. Now another breakthrough is stirring interest and excitement - the emergence of three-dimensional displays. Adding considerable new value to images and video, NTT DOCOMO has developed a portable 3D display system that enables viewers to view 3D images from any direction without having to wear those cumbersome glasses.

Traditional 3D display systems are based on the principle of stereoscopy, whereby the 3D effect derives from the difference between the images registered by the left and right eye as the result of their horizontal separation, a phenomenon known as binocular disparity. This type of 3D display has been incorporated into a host of products but is far from ideal because it usually requires viewers to wear special glasses to enjoy the 3D effect or, if 3D glasses are dispensed with, limits observation of the 3D effect to a very narrow range. The 3D display developed by NTT DOCOMO overcomes these shortcomings. Although we continue to rely on the principle of stereoscopy, we have adopted a new approach - known as high-density directional images display - that endows the object with very smooth and natural appearing motion as the observer's position changes (motion parallax) without the need for 3D glasses.

High-density directional images displays employ a large number of directional images - projections of a display target - with each image projected from a slightly different angle. As the viewer moves around the static display, the transition from one image to the next is so smooth and imperceptible that the viewer has the illusion of moving around a 3D object. Our most recently developed display allows objects to shift dynamically to match the viewing angle of the observer, and 3D action can be observed over a significant range (within a 60-degree horizontal angle and 30-degree vertical angle). A built-in camera senses the position of the viewer (the angle from which the viewer is observing the display), and automatically adjusts to that viewing angle in real time to maintain the 3D effect.

The 3D display is a high-definition liquid-crystal display to which a lenticular sheet has been attached, the latter essentially being a ribbed panel consisting of dozens of optical-grade cylindrical lenses arrayed in parallel vertical lines. The cylindrical lenses exhibit the 3D effect when viewed from a horizontal perspective, and diffuse light in the manner of ordinary glass when viewed from a vertical perspective.

In the case of ordinary 2D images, each point on the surface of a displayed object is represented by a single luminance value (pixel) in a one-to-one relationship, and viewers see exactly the same pixel regardless of the angle from which they are viewing the display. 3D images are fundamentally different from 2D images in that they have several subpixels. A cluster of multiple subpixels is known as a 3D pixel, and the lenticular sheet is attached to the display in such a way that each cylindrical lens overlaps several subpixels, each of which is emitting light in a different horizontal direction.

We think NTT DOCOMO's 3D display system has enormous potential. Objects have such a convincingly three-dimensional appearance that you want to reach out and touch them. We envision all sorts of imaginative applications for this technology to mobile phones including realistic games where the characters and images are rendered in 3D or mobile Internet shopping that allows customers to view potential purchases from virtually any direction.

i3dg turns iphone into 3d display

How’d you like it if you could turn your iPhone into a glasses-free 3D display?

i3dg_iphone_3d_display

By using an old-school technique with a half-silvered mirror placed at a 45-degree angle, along with a special app, the i3DG Palm Top Theater turns your iPhone or iPodTouch into a 3D display. By splitting images or video into three layers using the template below, then reflecting them off of the mirrors, it creates the illusion of depth.

i3dg_iphone_3d_template


Here’s a quick video, showing off the i3DG in action:

The devices and demo videos were created by media artist Jitsuro Mase, and have been making the rounds at interactive art exhibitions. No word on if and when they’ll put the gadget into production, or if it will remain a prototype for now.

Viewsonic 3DV5 Is a Pocket-Fitting 3D Camcorder

Viewsonic 3DV5 Is a Pocket-Fitting 3D Camcorder

Viewsonic announced their mini-sized 3D camcorder last month, but now they've finally brought it stateside. Not only does the 3DV5 pack two 5MP fixed focus cameras for 3D 720p video, it's also got a glassesless 3D display panel for playback.

Of course, the 3DV5 has the same problem that all 3D camcorders and cameras do: you're going to have to get yourself a 3DTV or 3D laptop to watch it on. The good news is that this particular mighty mite can also record in 2D, making it as present-ready as it is future-proof. And it might just be worth the $180 to have your bases covered. [ZDNet]

To 3-D or not to 3-D? 'Potter' people disagree

Radcliffe said he is delighted that the filmmakers and distributor Warner Bros. scrapped plans to convert "Harry Potter and the Deathly Hallows: Part 1" to 3-D. He also hopes they abandon their 3-D plans for "Part 2," due in theaters next July.

"If any film doesn't need a gimmick, it's these ones, and that's for me what 3-D is," Radcliffe said in an interview. "For me, 3-D adds nothing to the story."

It does add to the box office, however. Movies available in both two- and three-dimensional projection often derive two-thirds or more of their revenue from 3-D versions, with fans willing to pay the few dollars extra it costs to put on the dorky glasses that bring the illusion of depth to the images.

The filmmakers had been racing to create a 3-D version of "Deathly Hallows" in time for its theatrical debut this week, but they said they ran out of time to do it right.

"We lavish a huge amount of attention and care on the 2-D version, the normal version of the film," said producer David Barron. "We were just not prepared to throw off what you might call some half-assed version just for the sake of trying to generate more money."

How much more money? There's no way to pinpoint precisely what 3-D would have added to revenues for "Deathly Hallows," but producer David Heyman made an estimate.

"I think 10 to 20 percent, probably. On a film that's going to make $800 million at the box office, that's a lot of money," Heyman said. "Warner Bros. are going to have to alter their fourth-quarter projections because it's not in 3-D."

As bad as that sounds for shareholders, it's a rare instance of quality trumping commerce in greedy Hollywood. Warner Bros. pushed for a 3-D version but ultimately agreed to drop it once the filmmakers convinced studio heads it would be an inferior rush job.

Director David Yates, who shot both parts of "Deathly Hallows" simultaneously, said "lots of beautiful individual bits and pieces" of "Part 1" had been converted to 3-D, but other scenes simply did not look right.

With what the filmmakers learned on "Part 1" — and nearly eight months ahead of them — they are confident they can deliver a 3-D version of "Part 2" that lives up to the "Harry Potter" brand name.

"I think it's going to be really cool," Yates said. "We've been working with people since May on the whole 3-D thing, so it's not like we're starting from scratch. I want it to work. I really want it to work."

There are moments in the 2-D version of "Part 1" where the possibilities of 3-D can be clearly seen, including a scene where a giant snake hurtles itself at the camera and another where Harry's pet owl flies away from him toward the audience.

Such images were not created for 3-D jolt effect, though, since "Deathly Hallows" was not shot with 3-D in mind. The film was well into production before the digital 3-D craze took hold last year, culminating in James Cameron's sci-fi sensation "Avatar."

Digital 3-D comes in two basic flavors: Films such as "Avatar" specifically shot with 3-D cameras that create two slightly offset images, and movies converted to 3-D after the fact.

Done well, footage converted to 3-D can look great. George Lucas showed an impressive 3-D conversion of the opening scenes of 1977's "Star Wars" to theater owners at a convention in 2005, and the technology has advanced since then.

Lucas plans to release 3-D versions of all six "Star Wars" movies, while Cameron is converting "Titanic" for 3-D release.

As meticulous as Lucas and Cameron are, fans probably can expect top-of-the-line 3-D conversions. But some recent movies converted to 3-D have come off as hasty knockoffs to cash in on 3-D mania.

Critics carped that 3-D added little to such recent hits as "The Last Airbender," "Clash of the Titans" and even Tim Burton's blockbuster "Alice in Wonderland." Some claimed 3-D conversion jobs actually can be a distraction, leaving images looking smudged and blurry.

Radcliffe is not a fan of 3-D even when it's done well. He said that Christopher Nolan's sci-fi blockbuster "Inception" was the year's best film both visually and dramatically, "and that for me puts the 3-D argument to bed."

"`Avatar,' sure, it looked amazing, but not more amazing than `Inception,'" Radcliffe said. "And I thought about `Inception' for so much longer because it was a better film, because it was a more interesting film. And I don't think that technology is a substitute for story, which I think is how 3-D can sometimes be used."

Nolan, who also made "Batman Begins" and "The Dark Knight," is not shooting his next Batman movie in 3-D, either.

Warner Bros., which released "Inception" and the Batman movies, may be counting on a 3-D bonanza from next summer's finale to the "Harry Potter" franchise. Yet Radcliffe would like to see "Deathly Hallows: Part 1" work enough critical and commercial magic that the filmmakers and studio bosses will change their minds.

"What I'm hoping is that this film will get a good enough reaction so they all go, `Maybe we don't have to do the last one in 3-D. People don't miss it.' That's what I'm hoping for," Radcliffe said. "But it's sort of not in my control."
