The art and craft of digital design

August 3, 2006
When the Hollywood elite descends on Cannes, France, this week for the city's famous film festival, one of the most anticipated debut showings will be U2 3D, a feature-length U2 concert movie shot in 3D.

But don't worry: the glitterati at the U2 3D screening will not have to risk being seen in those awful red and blue glasses traditionally used to watch 3D movies. Instead, they'll be sporting sleek black glasses that are one piece of a new generation of digital 3D stereoscopic cinema technology that is taking the film industry by storm.

The technology is the work of two companies: Beverly Hills, Calif.-based Real D and Burbank, Calif.,-based 3ality. And it's clear that audiences are on board. When Disney's Chicken Little was released in 3D last fall, there were only 100 screens in the United States that could show the film. By the time the studio's Meet the Robinsons hit theaters this spring, there were 720 screens nationwide, and the companies expect more than 1,000 screens nationwide by fall.

3D cinema

In fact, as Real D and 3ality move forward with their technology, they are seeing broad interest from the studios. In addition to the Disney films already released, Sony put out Monster House in 3D last fall, Paramount is releasing Beowulf in 3D this fall and Dreamworks Animation in March said it would begin releasing all its films in 3D beginning in 2009.

Currently, some films are being released in both 2D and 3D formats, and audiences are seemingly clamoring to catch the latter and even pay more to do so.

"People will happily pay a premium to see the movie in 3D," said Tom Stephenson, president and CEO of Rave Motion Pictures, a Dallas-based theater chain. "The only frustration they have is if you're out of 3D seats and they have to see it in 2D."

Stephenson said that Rave theater customers are paying about $2 more to see films in 3D than they are for the same movies in 2D. And Dick Westerling, the vice president of marketing for Regal Entertainment Group, which operates 6,340 screens nationwide, says customers at his company's theaters are paying between $2 and $2.50 more to see films in 3D.

There are two sides to the technology: the content side, which is created by 3ality, and the exhibition side, which comes from Real D.

3ality CEO Steve Schklair said that his company has created 3D tools designed to "perfectly align" images taken from two separate motion-controlled digital cameras that are placed side by side--as the "left eye" and "right eye"--and used to shoot films in 3D.

"We believe that once you see something in this new format, it's kind of hard to go back. It's like black and white. Once you've seen color, you don't want to go back."
--Real D CEO Michael Lewis

The idea, Schklair said, is to efficiently take the images from the two cameras and manipulate them after they're shot so they match.

The technology is also designed to help easily blend the shot-by-shot depth of scene so that as a film cuts from one scene to another, viewers are not taken on a roller coaster ride of perception as was the case with the 3D films of old.

"On a cut-to-cut basis in the past, the depth of each shot was different," said Schklair, who added that watching such a film was tiring on the eyes after around 15 minutes. "But now, we're using these new tools that hand off the depth for each shot. So we transition the depth from shot to shot, so your eyes are led though the movie. So your eyes don't even notice."

Once 3ality's systems have processed the footage, it's up to Real D's systems to project it onto specially upgraded screens in the growing number of theaters using the technology.

Real D's systems process the images sequentially, projecting them at 144 frames per second--as compared with traditional 2D films being shown at 24 frames per second--making for what Real D CEO Michael Lewis says is a more comfortable experience than traditional analog 3D films.

The projectors display the image on specially designed screens that let the polarized images reflect toward moviegoers' eyes. The audience will still have to wear 3D glasses, but instead of the red and blue glasses so familiar to people of a certain age, they are more attractive circular polarized black glasses.

"We think the technology is really, really good," said Stephenson. "It's a transforming technology. It completely changes the experience. It sort of envelopes the (viewer). You're not watching it. You're almost in it."

Schklair said that making a film in 3D raises production budgets by between 5 percent and 20 percent, with the additional costs being more extreme for lower budget films.

Similarly, the theater installation of Real D's 3D technology--a software and digital hardware upgrade to the projectors, as well as to the screens--adds what has been reported to be around $25,000 to $30,000 a year in licensing fees.

Best of all, said Lewis, the upgrade takes only about an hour, and once done, theaters can switch back to 2D films in about five seconds.

Schklair thinks there will still be a market for 2D films looking forward--particularly smaller, dialogue-driven movies. But Lewis said he thinks that most films will be in 3D before too long.

"We believe that once you see something in this new format, it's kind of hard to go back," said Lewis. "It's like black and white. Once you've seen color, you don't want to go back."

It's True
I saw Meet the Robinsons in 3D on its opening weekend. It's really amazing and it doesn't give you a headache like some of the older 3D things did. It's worth the extra money.

Red and blue (or green) filters are NOT the traditional appliances for viewing 3D films. Most 3D films, such as Bwana Devil, Murders In The Rue Morgue, House Of Wax, etc., were shot & viewed with horizontally & vertically polarized filters. The author is confused 3D comic books with 3D movies. The 3D comics were generally printed in red & blue (or green) and viewed through similarly colored filters. Current 3D movies are shot and viewed with left hand circularly & right hand circularly polarized filters. These have the advantage of greater image separation (higher signal to noise ratio) and are able to pass more light than their linearly polarized predecessors.

Not Horizontal, vertical.... Diagonal
when H-V polarization is used, the left and right eye images are reversed if the glasses are folded backward.

To prevent this, the polarization was designed at 45 degree angles.

This left a problem that the viewer needed to keep his head level to preserve the angle or the wrong image would leak through. Circular polarization is a great improvement.

Super-Premium price
I stopped going to the regular cinema when the prices went over $7.00. No way am I paying $12 or more just to watch one in 3D. It is amazing that they can't figure out why attendance is down as the prices go up. Instead of going by gross ticket sales, they should start looking at the number of tickets sold.

TucsonAlexAZ - geeez dude, get a clue, be informed before blathering such an ignorant comment about the aformentioned. Put the viewmaster down and learn what a real modern 3D motion picture is all about - totally worth the extra $2.

3D at last
About time we had 3D films! Anyone who's been to Disney has seen the short ones there, using some very cheap, but effective 'glasses'. Hopefully, the experience here is also a little smoother- there was always something a little tacky about that. I wander if a special, 'projecting' screen is possible, as I can't see people forever wearing specs in a cinema.

Disneys Meet The Robinsons was written and created especially for 3D - to accentuate depth and the 3D visual experience.
