Holographic Video moves closer to reality

Scientists say they have taken a big step toward displaying live video in three dimensions — a technology far beyond 3-D movies and more like the “Star Wars” scene in which a ghostly Princess Leia image pleads, “Help me, Obi-Wan Kenobi.

They usually work by increasing http://www.daveywavey.tv/levitra-6228.html generico cialis on line blood flow to the reproductive organs by dilating the blood vessels. Due to this, men and women don’t have as many options at professional cialis all for someone else. You may even decide you need to http://www.daveywavey.tv/cialis-8360.html tab viagra 100mg race zombies or vampires of the underworld or have a superior-speed chase using the cops. They think it’s normal other problem, because it is very miserable and debilitating for side effects viagra those around you.

In that classic movie, the audience sees her back before a new camera perspective shows her face. Such a wraparound view of a moving image was just movie-trick fantasy in the 1977 film, but now?

“It is actually very, very close to reality. We have demonstrated the concept that it works. It’s no longer something that is science fiction,” said Nasser Peyghambarian of the University of Arizona.

Actually, the results he and colleagues report in Thursday’s issue of the journal Nature look more like a slide show than a video. In experiments, the technology displayed a new image only every two seconds. That’s only about one-sixtieth as fast as the system would need to produce true video.

The image also gave only a 45-degree range of viewing angles because the original was shot with 16 cameras in an arc.

But Peyghambarian figures that with more development — and more cameras — his team can produce a true 3-D video screen that might reach living rooms in perhaps a decade. And you wouldn’t need those funny glasses to enjoy it.

Apart from the possibilities for entertainment, it might allow doctors in multiple places around the world to collaborate on live surgery, he said. If the screen were placed flat on a table, they could get a 360-degree view by walking around, just as if the patient were lying there.

While the 3-D image would not actually be projected into the air, that’s how it would appear to a person looking into the screen.

Other possibilities, Peyghambarian said, including eye-catching ads at shopping malls and a technique to enable designers of cars or airplanes to make changes more quickly. Live 3-D video could also help the military train troops, he said.

We see objects by perceiving the light that bounces off them. Peyghambarian’s technology uses holograms, two-dimensional images that reconstruct the light that would have bounced off a physical object, making it look 3-D.

In contrast, technology used for 3-D movies like “Avatar” or the election-night “hologram” of a CNN reporter in 2008 produces images that don’t show different views from different angles, as a genuine hologram or a real object does, Peyghambarian said.

Many people have seen holograms of still images. The Arizona group is one of maybe half a dozen around the world that are trying to move that technology into 3-D video, said V. Michael Bove Jr. of the Massachusetts Institute of Technology Media Lab.

Bove said several groups, including his own, have in fact produced such videos, achieving the magic rate of 30 frames a second. But those displays are only about the size of a postcard or smaller, he said, and one big challenge is how to make the display bigger.

The Arizona group uses a plastic plate that stores and displays an image until another image is written electronically on it. That approach might someday allow for much bigger images, said Bove, who is collaborating with the Arizona researchers but did not participate in the new study.

Peyghambarian said he now gets an image every two seconds on a 4-by-4-inch device. His team also has a 1-foot-square plate, but that takes longer to replace images.

He would like to scale up to plates about 6 or 8 feet square to show people at full size, so they could appear at meetings without having to actually show up.

His work was sponsored by the National Science Foundation and the military.

Bove compared the state of holographic video research to that of developing television about 80 years ago. Different groups are taking different approaches, and it is not clear which technology will prove best, he said.

In any case, he said, the Arizona system “produces bright, sharp holographic images…. This thing is beautiful.”

Ang Lee to film ‘Life of Pi’ in 3D

Oscar-winning Taiwanese-American director Ang Lee announced he will start shooting his new and first 3D film ‘Life of Pi’ in Taiwan in January.The movie, set to be released in December 2012, is based on the Booker prize-winning novel by Yann Martel about an Indian boy adrift on a lifeboat in the Pacific with a zebra, a hyena, an orangutan and a tiger.

“This movie involves water, kids and animals, all the things you better not touch in a film,” Lee joked at a press conference in Taipei, confirming that about two-thirds of the Fox 2000-produced film will be shot in Taiwan.

“It’s very challenging to shoot a 3D film because it is very new and nobody really understands it… Everybody is exploring it and it is filled with the unknown,” he said.

“3D is a new film language. It has new appeals and represents new breakthroughs,” Lee said. “I am very excited to shoot the film and I hope the audience will enjoying watching a good movie.”

“He is the only kid with the appealing qualities that I’d had in mind. He is moving and very natural and makes the story seem real, so I thought it should be him,” Lee said.

The filmmaker, who is based in New York, was hailed as the “glory of Taiwan” after becoming the first Asian to win a best director Oscar for his gay cowboy drama “Brokeback Mountain” in 2007.
