TDVision Systems Displays Stereoscopic TDVSDK at the 2008 Game Developers Conference
3D-News Posted: Sunday, February 24, 2008 (9:56 UTC) | Posted By: Webmaster

TDVision Systems, Inc. showcases several stereoscopic enabled games optimized for multi-core Intel Processors at the 2008 Game Developers Conference in San Francisco, CA at the Intel Gaming Lounge.

As a member of the Intel Software Partner Program, TDVision is displaying the TDVSDK, a set of tools to enable DirectX and OpenGL game engines to present games in a natural manner emulating the way the human brain perceives 3D data. At the Game Developers Conference visitors experienced the TDVisor and were immersed in a virtual 72-inch diagonal screen.

"The thrill to dollar ratio for 2D technologies is now facing diminished returns. Stereoscopic 3D will add an exciting new class of PC game immersion, sales, and gamer to gamer enthusiasm," said Neil Schneider, CEO of Meant to be Seen (mtbs3d.com), the world's foremost authority group on stereoscopic 3D for consumers, and the home of the largest online S-3D community in the world. "Look at movies. Compared to 2D cinema, 3D movie sales easily earn 2:1 and 3:1 revenue. This is where the PC gaming industry is headed," he continued.

"We are getting a great response here at the GDC. We have rock star programmers and hardcore players getting their game on in true 3D and loving it. With the power of Intel Core Duo technology we can put the player inside the game," said Ethan Schur, Director of Marketing for TDVision.

TDVision is the only technology simultaneously compatible with 2D infrastructures and also is fully compatible with existing MPEG decoders. It is established and tested in mission critical military applications and electronics.

TDVision became part of the Intel Software Partner Program and created the TDVAlliance, a collaboration of hi-tech companies working to create an infrastructure that will be the catalyst for TDVision's multi-purpose 3D technology. Integrated Micro Displays Limited, Himax Display, 3D-ETC and The DiMonte Group all participate as TDVAlliance members.

TDVision Systems, Inc. is the owner of several 3D-related patents for proprietary system architectures, which will propel breakthroughs in providing true 3D through new digital technologies. These technologies enable the acquisition, emulation and processing of a 3D image from a video stream or computer-generated image. This architecture also allows the use of current existing infrastructures, and with the addition of TDVision's hardware, enables true 3D in High Definition.

New Technology Makes 3-D Imaging Quicker, Easier
3D-News Posted: Wednesday, February 20, 2008 (6:09 UTC) | Posted By: Webmaster

Technology invented by scientists from The Johns Hopkins University and Ben-Gurion University of the Negev can make three-dimensional imaging quicker, easier, less expensive and more accurate, the researchers said.

This new technology, dubbed FINCH, for Fresnel incoherent correlation Holography, could have implications in medical applications such as endoscopy, ophthalmology, CT scanning, X-ray imaging and ultrasounds, co-inventor Gary Brooker said. It may also be applicable to homeland security screening, 3D photography and 3D video, he said.

A report presenting the first demonstration of this technology — with a 3D microscope called a FINCHSCOPE — will appear in the March issue of Nature Photonics and will be available on the Nature Photonics Web site on Feb. 17. "Normally, 3D imaging requires taking multiple images on multiple planes and then reconstructing the images," said Brooker, director of the Johns Hopkins University Microscopy Center on the university's Montgomery County Campus.

"This is a slow process that is restricted to microscope objectives that have less than optimal resolving power," said Brooker, a research professor of chemistry in Krieger School of Arts and Sciences who also has an appointment in the Whiting School of Engineering Advanced Technology Laboratory. "For this reason, holography currently is not widely applied to the field of 3D fluorescence microscopic imaging."

The FINCH technology and the FINCHSCOPE uses microscope objectives with the highest resolving power, a spatial light modulator, a charge-coupled device camera and some simple filters to enable the acquisition of 3D microscopic images without the need for scanning multiple planes.

The Nature Photonics article reports on a use of the FINCHSCOPE to take a 3D still image, but moving 3D images are coming, said Brooker and co-inventor Joseph Rosen, professor of electrical and computer engineering at Ben-Gurion University of the Negev in Israel.

"With traditional 3D imaging, you cannot capture a moving object," Brooker said. "With the FINCHSCOPE, you can photograph multiple planes at once, enabling you to capture a 3D image of a moving object. Researchers now will be able to track biological events happening quickly in cells."

"In addition, the FINCH technique shows great promise in rapidly recording 3D information in any scene, independent of illumination," Rosen said.

The research was funded by CellOptic Inc. and a National Science Foundation grant with the technology being demonstrated using equipment at the Johns Hopkins Montgomery County Campus Microscopy Center.

Brooker and Rosen are founders of CellOptic Inc., which owns the FINCH technology. The terms of Brooker's involvement with CellOptic are being managed in accordance with Johns Hopkins' conflict of interest policy.

Under the Sea 3D to be next original IMAX 3D film from Warner Bros. Pictures and IMAX
3D-News Posted: Thursday, February 7, 2008 (20:41 UTC) | Posted By: Webmaster

Warner Bros. Pictures Inc. and IMAX Corporation announced that the official title of their third original IMAX® 3D co-production will be Under the Sea 3D. Production began last month in Papua, New Guinea, where the film crew is photographing some of the most extraordinary marine wildlife ever captured on film.

Slated for release in February 2009, Under the Sea 3D (previous working title, 'Deep Sea-quel') will offer a uniquely inspirational and entertaining way to explore the impact that global climate change has had on ocean wilderness. Moviegoers will be able to experience face-to-face encounters with some of the most mysterious and stunning creatures of the sea. In IMAX 3D, the images literally leap off the screen and float around the theatre, putting the audience IN the movie.

"We're very excited about this film," said Alan Horn, President and Chief Operating Officer of Warner Bros. "In addition to bringing some of the most exotic underwater creatures to light for the first time, Under the Sea 3D will also thoughtfully explore the effects of global warming on our oceans and their wildlife. We're proud to be a part of this important production that will both fascinate and enlighten audiences."

"We are thrilled production is underway for Under the Sea 3D, and we are delighted to expand our original IMAX 3D library with another project from the talented filmmaking team behind Deep Sea 3D," said Dan Fellman, president, domestic distribution, Warner Bros. Pictures. "Moviegoers are continuing to buy tickets to Deep Sea 3D, demonstrating the strong appeal of this subject matter when combined with the immersive nature of IMAX's format."

Under the Sea 3D follows the 2006 box office hit Deep Sea 3D, which has grossed more than $60 million worldwide - with more than 40 percent of the film's total box office receipts coming from international IMAX locations. Deep Sea 3D continues to draw audiences after 100 weeks in release, demonstrating the strong legs and tremendous appeal that original IMAX 3D productions have become famous for throughout the exhibition industry.

"Deep Sea 3D continues to deliver a premium cinematic experience that keeps moviegoers returning to IMAX® theatres year after year, and we anticipate another hit with Under the Sea 3D," said Greg Foster, Chairman and President, IMAX Filmed Entertainment. "We are amazed by what the film crew has already encountered, and we're excited to once again work with our partners at Warner Brothers Pictures to share with audiences another original IMAX 3D adventure from one of cinema's most esteemed filmmaking teams."

Under the Sea 3D will be shot by award-winning Director/Cinematographer Howard Hall, produced by Toni Myers, executive produced by Graeme Ferguson, and produced for Howard Hall Productions by Michele Hall. In addition to last year's Deep Sea 3D, Hall, Ferguson and Myers were all part of the accomplished filmmaking team behind IMAX's first underwater 3D adventure, Into The Deep, which has grossed more than $70 million since its 1991 release.

"The dazzling colors and amazing animals we'll see filming from South Australia to the Indo-Pacific are made for the grand scale and intensity of IMAX 3D," said Toni Myers, the film's producer, editor and writer. "But these spectacular yet delicate ecosystems are threatened by climate change. It's vitally important to promote awareness of that, especially among the young people who will be the stewards of our planet's health and well-being."

University of Arizona optical scientists add new, practical dimension to holography
3D-News Posted: Thursday, February 7, 2008 (7:43 UTC) | Posted By: Webmaster

University of Arizona optical scientists have broken a technological barrier by making three-dimensional holographic displays that can be erased and rewritten in a matter of minutes.

The holographic displays – which are viewed without special eyewear – are the first updatable three-dimensional displays with memory ever to be developed, making them ideal tools for medical, industrial and military applications that require "situational awareness."

"This is a new type of device, nothing like the tiny hologram of a dove on your credit card," UA optical sciences professor Nasser Peyghambarian said. "The hologram on your credit card is printed permanently. You cannot erase the image and replace it with an entirely new three-dimensional picture."

"Holography has been around for decades, but holographic displays are really one of the first practical applications of the technique," UA optical scientist Savas Tay said.

Dynamic hologram displays could be made into devices that help surgeons track progress during lengthy and complex brain surgeries, show airline or fighter pilots any hazards within their entire surrounding airspace, or give emergency response teams nearly real-time views of fast-changing flood or traffic problems, for example.

And no one yet knows where the advertising and entertainment industries will go with possible applications, Peyghambarian said. "Imagine that when you walk into the supermarket or department store, you could see a large, dynamic, three-dimensional product display," he said. It would be an attention-grabber.

Tay, Peyghambarian, their colleagues from the UA College of Optical Sciences and collaborators from Nitto Denko Technical Corp., which is an Oceanside, Calif., subsidiary of Nitto Denko, Japan, report on the research in the Feb. 7 issue of the journal Nature.

Their device basically consists of a special plastic film sandwiched between two pieces of glass, each coated with a transparent electrode. The images are "written" into the light-sensitive plastic, called a photorefractive polymer, using laser beams and an externally applied electric field. The scientists take pictures of an object or scene from many two-dimensional perspectives as they scan their object, and the holographic display assembles the two-dimensional perspectives into a three-dimensional picture.

The Air Force Office of Scientific Research, which has funded Peyghambarian's team to develop updatable holographic displays, has used holographic displays in the past. But those displays have been static. They did not allow erasing and updating of the images. The new holographic display can show a new image every few minutes.

The four-inch by four-inch prototype display that Peyghambarian, Tay and their colleagues created now comes only in red, but the researchers see no problem with developing much larger displays in full color. They next will make one-foot by one-foot displays, then three-foot by three-foot displays.

"We use highly efficient, low-cost recording materials capable of very large sizes, which is very important for life-size, realistic 3D displays," Peyghambarian said. "We can record complete scenes or objects within three minutes and can store them for three hours."

The researchers also are working to write images even faster using pulsed lasers.

"If you can write faster with a pulsed laser, then you can write larger holograms in the same amount of time it now takes to write smaller ones," Tay said. "We envision this to be a life-size hologram. We could, for example, display an image of a whole human that would be the same size as the actual person."

Tay emphasized how important updatable holographic displays could be for medicine.

"Three-dimensional imaging techniques are already commonly used in medicine, for example, in MRI (Magnetic Resonance Imaging) or CAT scan (Computerized Axial Tomography) techniques," Tay said. "However, the huge amount of data that is created in three dimensions is still being displayed on two-dimensional devices, either on a computer screen or on a piece of paper. A great amount of data is lost by displaying it this way. So I think when we develop larger, full-color 3D holograms, every hospital in the world will want one."
