National Geographic to release 'U2 3D'
Posted by Daniel Terdiman
A few months ago I wrote that one of the hottest tickets at this year's Cannes Film Festival was U2 3D, a 3D concert film about the popular band made using the technology of two companies helping to make 3D films a regular part of the movie going experience: 3ality and Real D.
Now, U2 3D is set to be accessible even to those of us who couldn't make it to the Riveria to hobnob with Leo and Bobby and the rest of the gang.
According to a release I got this morning from National Geographic Cinema Ventures, the outfit plans to make U2 3D its first "major international" release, and expects the film to hit theaters equipped to show 3D movies in January.
I'm kind of excited by this, even though I'm not a huge U2 fan. I think that this is exactly the kind of movie that could really get people to see the value of 3D, and that's in spite of evidence that the market for such films is taking off in a big way.

Phillips Goes 3-D…
Phillips Goes 3-D…
Published October 25th, 2007 in Emerging Technology.
Get ready to dump those funky 3-D glasses…
Phillips Electronics has been working on a technology that will deliver a pseudo 3-D image using a special flat panel display - no colored specs required. Called ‘WoWvx’, this technology ties together unique display optics, a video meta-data stream that adds depth information to traditional 2-D images and some clever software processing to pull it all together.
The optics piece of WoWvx is based on a panel of lenticular lens placed on the face of the display. These lens allows the system to provide each eye of the viewer with its own distinct image. These distinct images offer a slightly different perspective of the same main image, creating the illusion of depth. This is exactly how ours eyes work in the real world - each one sees a slightly different image, which our brain combines to give us spacial perception.
blog-_d-postcard-lg.jpgThe concepts behind the optical technology used here have been around for a while. While clearly much more refined, the lens panel used here plays a similar role to the top layer used in those 3-D post cards that were popular in the 1960’s - the ones that used to show different images when you held the card at different angles. The difference - and it’s a BIG difference - is that this system can deliver these specific independent images to each eye simultaneously.
For this lens system to work, there is a hefty chunk of technology behind it that needs to figure out how to construct these two distinct images in the first place.
And that’s where the interesting stuff really kicks in…
For each frame of video, a map needs to exist defining the depth of each pixel in the frame. This is similar to something in video post production called ‘2.5-D’. In 2.5-D, flat 2-D images are extruded to create depth. These extruded elements can then be manipulated independently, and a ‘virtual camera’ can move around the extruded picture in 3-D, albeit with some limitations, to create a series of moving images that appear to have depth. This type of breakdown looks something like this:
blog-25d-images.jpg
In the Phillips system, this depth defines the distance of each pixel from the lens of the camera that shot the image. It can be calculated through various mechanisms directly from 2-D images (using methods like blur analysis for example), or captured at the same time as the image. Software is able to take these depth values and use them to derive two mathematically generated images that show slightly different perspectives on the original image. These two images are vertically interlaced on the screen, and the lenticular lens take it from there to deliver them to each eye.
And there you have it. 3-D! (sorta) …
While Phillips is currently targeting WOWvx at commercial venues, it seems like it eventually could find a place in home theaters as well. Here is a short video by Phillips advertising this system:
To see a how the meta-data around depth is represented, check out some of the videos over at WoWvx.com. With each of these videos, the left side of the screen shows the original image stream, and the right side shows it’s corresponding ‘depth map’. Lighter shades of gray indicate the corresponding pixels are closer to the camera and darker shades mean they are farther away. The two streams combine to make ‘3-D’ happen.
If this technology eventually takes off, those multi-colored ’stereo-vision’ glasses will be a thing of the past.
Hopefully the same will be true for those cheesy 3-D movies…

Dolby stakes its claim in 3D movie tech
Dolby stakes its claim in 3D movie tech
By Stephen Shankland, News.com
Published on ZDNet News: Oct 8, 2007 4:00:00 AM
SAN FRANCISCO--When Paramount Pictures' 3D movie Beowulf debuts on November 16, the battle between an Anglo-Saxon hero and various monsters won't be the only one moviegoers will witness.
The Robert Zemeckis film also will be first major time that Real D, one of the companies that made the current renaissance of 3D movies possible, directly faces a newer challenger, Dolby 3D from Dolby Laboratories.
Beowulf will show using Real D's technology on 1,000 screens nationwide, Chief Executive Michael Lewis said. Dolby isn't saying yet how many will use Dolby 3D, but it's racing to install its technology as widely as possible, limited chiefly by the rate that partners manufacture its 3D glasses.
"Real D is leading the pack, since they have the widest distribution, but everyone is watching with anticipation," said Aaron Parry, chief executive of production company Main Street Pictures, which Paramount hired to evaluate the current state of stereoscopic filmmaking.

Ultimately, the race to spread 3D movie technology could hasten the day that many in the industry see as inevitable, when 3D movies escape their history as off-the-wall spectacle and become the norm. In this view, the shift to 3D is just another overhaul of the entertainment business, just like the arrival of sound and color in the last century.
"I think in 10 years you can say entertainment will feel like you're there. It will completely blur the line between the experience you took physically and the experience you took visually," said Vince Pace, whose company, Pace co-developed with James Cameron the Fusion 3D camera being used in that director's 2009 movie, Avatar.
It's no secret why the industry would be eager for a cinematic revolution. Big flat-panel displays and surround sound made home theater compelling at the same time the studios were financially stagnant. 3D versions of movies such as Chicken Little have generated more revenue than their 2D equivalents financially, and the industry expects more of the same.
"We believe that 3D has the potential to meaningfully boost growth, by allowing theaters to offer a new visual experience that we believe will drive incremental attendance and price hikes," JPMorgan analyst Barton Crockett said in a September report.
He estimated 3D movies will draw 10 percent more viewers than 2D equivalents, and each person willing to pay about $3.50 more per ticket in 2009. That means $300 million to $400 million in additional earnings for theater companies--about a fifth of the total box-office take by 2011. The number of 3D-equipped screens should jump to 7,000 by 2010, he predicted.
Most expect home theater to lag 3D in movie theaters. Even when it catches up, "The biggest problem is that 3D on a small screen is not satisfying in same way as in big screen. It is what you call an immersive experience," said Dave Schnuelle, Dolby's senior director for image technology.
Antipiracy is a side benefit. Dreamworks Animation CEO Jeffrey Katzenberg has observed, "Ninety percent of all piracy comes from a camcorder aimed at the screen. You can't camcorder 3D movies."
However, building a 3D future is difficult.
Inside the technology
Real D and Dolby rely on the same basic idea to give an audience the illusion of depth: show images that differ slightly in vantage point to each of a viewer's eyes. The viewer's brain will reconstruct the third dimension, just as it does in the real world.
Both companies require glasses to ensure each eye gets only the correct view; Real D uses circular polarization while Dolby uses a color-filtering technology licensed from Infinitec. The light is separated into the left-eye and right-eye views at the projector, switching back and forth 144 times per second.
With the new method, "there's no eye fatigue like in the 1950s and 1970s," said Tim Partridge, Dolby's head of products and technology.
In Dolby 3D, a spinning CD-size wheel between the lamp and the digital projector alternately lets through one set of light frequencies or another--two slightly different versions of the red, green and blue primary colors for each eye. The wheel spins six times for each movie frame, with the digital projector synchronized to show the appropriate eye's image.
In contrast, Real D uses an electronic filter called a Z-screen that circularly polarizes the light two different ways after it leaves the projector, also switching back and forth six times per frame to avoid flicker. Circular polarization--a complicated transformation of light's electromagnetic properties--requires the use of a special silver screen that retains the polarization as the light reflects back toward the audience.
Another company in Korea, Masterimage, also is trying to get into the market with an approach that uses a spinning wheel in front of the projector to apply the circular polarization.
Correction: This story misidentified the studio for which Main Street Pictures Chief Executive Aaron Parry conducted a study of 3D moviemaking. Paramount Pictures hired him.
Each technology has its advantages and drawbacks. Dolby 3D's glasses are difficult to manufacture and therefore expensive--$50 right now, though the company expects prices will drop. They must therefore be returned after use and washed in an automated washer. Real D's 5-cent, disposable glasses can be branded with promotional graphics from the movie.
Dolby 3D has an advantage with movie screens. Real D requires theaters to install the special silver screens, which JPMorgan estimates cost $5,500 apiece. Silver screens offer higher reflectivity and work with 2D movies as well, but there's concern that despite advances they suffer from a bright central "hot spot." Dolby 3D uses conventional white screens, which means theaters can move 3D movies to smaller screens as a movie runs its course at a theater.
Real D seems to have the edge for maximum screen size, though--an important consideration given that both cut down the amount of light to less than a sixth of what a conventional 2D movie projects. Dolby is cagey about how large a screen Dolby 3D can use, though executives say it's been used to show movies on 38-foot screens. Real D, though was at 47 feet during debut and this year should reach beyond 60 feet early next year, said Real D president and co-founder Joshua Greer.

Another factor is how well separated the left-eye and right-eye views are, so that light from one doesn't leak into the other. Real D has "ghostbusting" technology to electronically counteract this problem, and it's working to move it from a digital processing step to a real-time add-on. Dolby, though, boasts that its technology requires no ghostbusting at all.
Neither rival is standing still. "Both are to some degree in their infancy," Parry said. "They'll change radically in the next couple years."
3D movie-making: a new nut to crack
Making 3D movies in the first place is another challenge, with production costs somewhere between 10 percent to 20 percent higher, according to various industry estimates. There, too, technology is changing fast, though.
3D filming has been hampered by technical challenges. For live-action movies, two cameras must be closely coordinated, with risks increasing as cameras move or lenses zoom. Computer-generated animations are easier because they're typically already designed in 3D and therefore require only more computer hours to render the second viewpoint.
Pace is one company trying to address the live-action difficulties, and its 3D cameras have won over Doug Schwartz, creator of the Baywatch TV series and now the chairman of Stereo Vision Entertainment, which aims to bring smaller-budget 3D movies to the screen.
"The (3D) camera used to be size of a VW bug. But you can do anything now--handheld, Steadicam, underwater, dollies, zoom, cranes," he said. Also important: technology from Quantel lets directors review the shot immediately, in 3D, on the set.
Tools are still missing from 3D production, though, said Pierre Raymond, president and founder of Hybride Technologies, a visual effects company that's working Journey 3-D, a new take on the Jules Verne's Journey to the Center of the Earth. For example, a standard "rig erase" operation, using computers to digitally erase gear such as wires to suspend actors in the air, is much more complicated than in 2D.
"If do in it 3D, you will erase something on the right eye, and you will not see it. You erase it on the left eye, and you will not see it. When you put stereo glasses on, bang, you see the patch," he said.
Three-dimensional movies are still a novelty, and movies are trying to milk it for all it's worth. "Every time you bring a new technology to market, you will pass the gimmicky stage," Raymond said.
Take Schwartz's work, which is Stereo Vision's first project. Planned for Halloween 2008, Aubrey Blaze Piranhas 3-D features video-game creators who are trapped in Brazilian caves and must reckon with mutant flying carnivorous fish.
"Water is one of best environments for 3D, because things float--they're in the middle of the screen and coming right out at you," Schwartz said. Stereo Vision also is working to exploit the 3D possibilities of restaurant waitresses in South Beach, Miami with a comedy called Hooters 3DD.
But there are limits, even with movies that embrace 3D's shock value. "You don't want to be jarring to the audience," Schwartz said. For example, MTV-style fast cuts from one scene to another are a no-no because audience members must refocus.
Most, including Real 3D's Lewis, expect a more easygoing era to arrive, with 3D used to involve people more deeply in the narrative. "Ideally we want to make you feel like you're part of the movie and less like there are things flying out at you."

Digital Cinema At the 2007 NAB: 3D Controversy
Apr 16 2007 3:00PM
Continued from 'Digital Cinema At the 2007 NAB: Steady Progress'....
The last presentation in this panel, from Dave Schnuelle, Senior Director of Image Technology at Dolby Labs, bears closer scrutiny. As I previously mentioned, the presentation of Chicken Little that I saw in late 2005 was branded as 'Dolby Digital Cinema' but used Real D 3-D projection and glasses technology, a moniker morass that I found confusing at the time. I'm less confused now, because Schnuelle tossed the audience the first few tantalizing crumbs of Dolby's unique long-term approach to 3-D projection.
To explain what little we now know about Dolby 3D Digital Cinema (note the name change), I'll begin by reminding you that the objective of any 3D display system is to present unique, perspective-altered versions of a given scene to a viewers' right and left eyes. Real D, as I've earlier mentioned, does this by successively projecting 'right' and 'left' versions of a given frame, with varying polarization characteristics, coupled to varying polarization responses of the right and left lenses in the viewers' glasses. NuVision's approach, conversely, projects the right and left views of a scene polarization-unaltered; it relies on alternately blocking-and-passing LCD shutters in the glasses to route the correct image to its matching eye.
The original approach to 3D, however, is the so-called anaglyph technique, known to any of you who've ever donned a set of red- and blue-lens glasses. The right and left versions of the scene, contained within the same image (therefore making the approach amenable to conventional 24 fps projection equipment), are correspondingly color-deficient. And, as any of who who've ever donned a set of red-and-blue glasses also know, anaglyph doesn't work very well. Among other things, there's a fair bit of image leakage to the unintended eye; said more precisely, the technology's extinction ratio is low. And each eye's view is missing a significant percentage of the full visible spectrum, requiring imperfect interpolation 'blending' image repair within the viewers' brains.
Dolby is, it seems from what Schnuelle said Saturday morning, going Back The Future with their under-development 3D technology. Schnuelle put the classic color gamut 'triangle' on-screen and then, in very general terms, explained that in Dolby 3D Digital Cinema, each eye's image would be based on slightly different RGB 'primaries' (presumably filtered by more exotic filtered lenses in the glasses). Unlike with anaglyph, with Dolby 3D Digital Cinema each eye gets a full RGB image, and Schnuelle took great pains to emphasize that the left- and right-view images would be color-indistinguishable from each other when viewed through the glasses.
Some other notes from Schnuelle's pitch:
Three fundamental design goals for Dolby 3D Digital Cinema were that it must be practical (must integrate easily into current theater operations), high quality (superior pictures, eliminate previous limitations), and cost-effective (must be a good investment for exhibitors and studios). It uses a color filter wheel, albeit not in image-forming path, instead in the path of the lamp assembly feeding the light engine. It employs a standard projector with a simple filter accessory; filter placement reduces stress on the optical assembly. Dolby 3D Digital Cinema works fine with a standard white screen (it also works with silver, but this isn't necessary). It delivers great 3D from every seat, using comfortable, lightweight passive glasses, and providing sharp, clear images with excellent color fidelity. It also provides a simplified, less costly process for creating and distributing 3D content.
Digital Cinema At the 2007 NAB: 3D Controversy
Apr 16 2007 3:00PM
Continued from 'Digital Cinema At the 2007 NAB: Steady Progress'....
The last presentation in this panel, from Dave Schnuelle, Senior Director of Image Technology at Dolby Labs, bears closer scrutiny. As I previously mentioned, the presentation of Chicken Little that I saw in late 2005 was branded as 'Dolby Digital Cinema' but used Real D 3-D projection and glasses technology, a moniker morass that I found confusing at the time. I'm less confused now, because Schnuelle tossed the audience the first few tantalizing crumbs of Dolby's unique long-term approach to 3-D projection.
To explain what little we now know about Dolby 3D Digital Cinema (note the name change), I'll begin by reminding you that the objective of any 3D display system is to present unique, perspective-altered versions of a given scene to a viewers' right and left eyes. Real D, as I've earlier mentioned, does this by successively projecting 'right' and 'left' versions of a given frame, with varying polarization characteristics, coupled to varying polarization responses of the right and left lenses in the viewers' glasses. NuVision's approach, conversely, projects the right and left views of a scene polarization-unaltered; it relies on alternately blocking-and-passing LCD shutters in the glasses to route the correct image to its matching eye.
The original approach to 3D, however, is the so-called anaglyph technique, known to any of you who've ever donned a set of red- and blue-lens glasses. The right and left versions of the scene, contained within the same image (therefore making the approach amenable to conventional 24 fps projection equipment), are correspondingly color-deficient. And, as any of who who've ever donned a set of red-and-blue glasses also know, anaglyph doesn't work very well. Among other things, there's a fair bit of image leakage to the unintended eye; said more precisely, the technology's extinction ratio is low. And each eye's view is missing a significant percentage of the full visible spectrum, requiring imperfect interpolation 'blending' image repair within the viewers' brains.

Tools tweak next generation of 3-D
Technology applied to mobile phones, PCs
By DARCY PAQUET
The next big thing in exhibition has been around for more than 50 years, but proponents insist that this time, 3-D is here to stay.
This year's special focus on 3-D at Bifcom covers the technology from several perspectives, including exhibition, production and the conversion of 2-D material to 3-D (a process known as dimensionalization).
Latter process was illustrated by Matthew DeJohn of In-Three with a presentation of more than 10 still cuts from "Star Wars: Episode 3" and Korean hit "The Host."
However, participants also emphasized that 3-D is set to invade more than just the traditional cinema.
Korean firm MasterImage had specialized LCD screens on display that can provide 3-D imagery ranging in size from 2.2 inches to 19 inches without any need for glasses.
The first mobile phone equipped with MasterImage's screens will go out in China in November, while mobile PCs and MP4 players will follow in the next six months.
Other applications include use in PC monitors (already launched last December) and in special coin-operated viewing devices that are being prepped for use in theater lobbies.
MasterImage is also emerging as a rival in Asia to firms specializing in 3-D projection such as RealD, Dolby and NuVision.
Company's internally developed single-projector type system has been adopted by Korea's largest exhibitor CJ CGV, and was also showcased this spring at the 4-D airport theater in Hong Kong. (4-D refers to 3-D imagery combined with other sensory effects including smoke, vibrating chairs, moving lighting, etc.)
It was clear from technical demonstrations that the hardware required for 3-D screenings is advancing quickly.
"There is no longer any excuse for headaches or eye fatigue in 3-D screenings," said DeJohn at an afternoon panel. He maintained firms are also within reach of so-called "perfect 3-D," meaning an image without any blemishes, exactly as the director intended it.
But the availability of content produced specifically for the 3-D medium will be a significant factor in pushing the new technology. Lee Young-hoon, prexy of MasterImage, estimates the first Korean 3-D film will be made in 2009, when according to Screen Digest there will be over 5,000 digital 3-D screens in use across the world.
That same year, James Cameron's ambitious "Avatar 3-D" is scheduled to hit screens, and the success or failure of that title could have a significant effect on the future development of the industry.
