‘Perfect black’ coating can render a 3D object flat

A carbon nanotube coating developed at the University of Michigan acts as a "magic black cloth" that conceals an object's three-dimensional geometry and makes it look like a flat black sheet....

"It's not cloaking, as the object can still cast a shadow. But if you put an object on a black background, then with this coating, it could really become invisible." ...

Here's how the new coating works: Human eyes perceive an object based on how it reflects or scatters light. The "refractive index" of this new coating is similar to that of air, meaning light traveling through air doesn't scatter or reflect when it hits the coating.

It's well known that carbon nanotubes are capable of absorbing light, but the researchers were able to push it to such a high percentage by spacing them just right.

The "perfect black" material Guo's team created for this coating has a host of varied applications. It could possibly be used in display screens for ultra-high contrast and a crisper picture.  ...

Norwegian boy cross-eyed after watching 3D movie

Shocked cinema manager considers warning cinema-goers about possible effects of watching 3D movies.

Julian Mathisen, from Honningsvag in Norway, came down with some bizarre symptoms after returning home from a movie theatre. The six year old appeared cross-eyed to his stunned father, and also complained of double-vision, headaches and nausea."After he came home from the movie I saw that there was something strange about his eyes," his father said. "One eye squinted, and he complained that he saw double."

Julian saw doctors and opticians following the ordeal, and they agree that the boy must have had a latent visual defect all along that was triggered by the 3D images on screen.

"You can get different kinds of ailments from this. Julian's case is extreme. However, diplopia, migraine, nausea and discomfort may occur," said Hans Torvald Haugo, Chief Advisor for theNorwegian Opticians Association. ...

Apple Wins Secret Patent for High-End 3D Object Recognition

The US Patent and Trademark Office officially published a series of newly granted patents for Apple Inc. today and one of them was a real surprise. Apple has been granted a major patent for 3D object recognition that will allow future iPads to advance graphics like MRI images for use in hospitals and other enterprise and military applications covering high-end security systems using advanced biometrics. Apple secretely acquired this patent at some point in the past from Swedish inventors. When the connections to this patent unfold, you'll be both surprised and excited about what this means for future iOS devices.

To 3D Or Not To 3D: Buy The Right Hugo Ticket

Final Verdict: This is the only perfect score I've given in To 3D or Not To 3D, and I don't imagine I'll be giving another one any time soon. The 3D in Hugo isn't just masterfully executed, and it doesn't just enhance every beautiful shot in the film. It's integral to understanding the film, the way it hearkens back to the earliest days of cinema, the way it talks about magic tricks and new technology as new ways of telling cinematic stories. Martin Scorsese probably understands movies better than anyone on earth, and he's proven that 3D can be as important as color or CGI. You owe it to yourself to see how well he proves it.

Martin Scorsese Talks ‘Hugo,’ Recurring Nightmares and How His 12-Year-Old Rules the Roost

...

HOW SCORSESE'S $100 MILLION-PLUS 3D HUGO HAPPENED
Scorsese was quite drawn to a film adaptation of Brian Selznick's 2007 novel The Invention of Hugo Cabret. Ostensibly a family film, the 3D Hugo is just as much an exploration of the power of cinema and the lost legacy of seminal artist George Melies. Producer Graham King, who financed the movie through his GK Films, first optioned the novel with Johnny Deppwhen both had production deals at Warner Bros., months before Scholastic Press even published the book in January 2007. (The project eventually migrated to Sony, then Paramount, in search of a Thanksgiving holiday slot; it opens Nov. 23). Scorsese and King already were talking about turning it into a feature together when they won Oscars for The Departed, the same weekend that Cabret hit No. 1 on The New York Times best-seller list. While John Logan, who had written The Aviator for Scorsese, worked to nail down a script, Scorsese went off to make Shutter Island for Paramount. Other filmmakers were interested inHugo, but King waited. When Scorsese had completed Shutter Island and was finally free to tackle Hugo in the summer of 2010, he told King that he wanted to try shooting in 3D for the first time. Although the cameras and extra tech crew would add 15 percent to the $100 million-plus budget, King felt the 3D would also create an intriguing marketing hook: a vaunted old-school filmmaker taking on the newest of technologies.  ...

The new dimension of holography

... Unlike the materials available at present, these photopolymer films require no subsequent chemical or thermal treatment, which make them suitable for the cost-effective mass-production of volume holograms.  ... Unlike traditional holograms, the background of volume holograms need not be metallic.  ...The color of the portrait or logo does not change depending on the angle at which it is viewed, meaning there is no rainbow effect.  ...

SFU Gallery celebrates Jerry Pethick’s ventures into photoarrays

The arrays involve the creation of an integral, three-dimensional image by mounting rows of serial photos behind corresponding rows of Fresnel lenses (plastic lenses with concentric grooves on their surfaces). Because of their low resolution and dreamily “defocused” quality, Pethick wrote in a 1999 artist’s statement, these images lend themselves to metaphors of memory and imagined space. They are a low-tech exploration of the high-concept realm of optics—of the physical laws that govern the way we visually perceive the world. ...
