Digital 3D

Last updated

Digital 3D is a non-specific 3D standard in which films, television shows, and video games are presented and shot in digital 3D technology or later processed in digital post-production to add a 3D effect.

Contents

One of the first studios to use digital 3D was Walt Disney Pictures. In promoting their first CGI animated film Chicken Little , they trademarked the phrase Disney Digital 3-D and teamed up with RealD in order to present the film in 3D in the United States. A total of over 62 theaters in the US were retrofitted to use the RealD system. The 2008 animated feature Bolt was the first movie which was animated and rendered for digital 3D, whereas Chicken Little had been converted after it was finished. [1] Even though some critics and fans were skeptical about digital 3D, it has gained in popularity. Now there are several competing digital 3D formats including Dolby 3D, XpanD 3D, Panavision 3D, MasterImage 3D and IMAX 3D. The first home video game console to be capable of 3D was the Master System in which a limited number of titles were capable of delivering 3D.

History

A first wave of 3D film production began in 1952 with the release of Bwana Devil and continued until 1955, a period known as the golden era of 3D film. Polarized 3D glasses were used. It was among several gimmicks used by movie studios (such as Cinerama and Cinemascope) to compete with television. A further brief period of 3D movie production occurred in the early 1980s.

After announcing that Home on the Range would be their last hand drawn feature and in fear that Pixar would not re-sign for a new distribution deal, Disney went to work on Chicken Little . The RealD company suggested that Disney use their 3D system and after looking at test footage Disney decided to proceed. In 2005, Chicken Little was a success at the box office in both 2D and 3D screenings. Two more films followed in their classic feature animation - Meet the Robinsons and Bolt - along with several others. Since then many film studios have shot and released films in several digital 3D formats. In 2010, Avatar became the first feature film shot in digital 3D to win the Academy Award for Best Cinematography and was also the first feature film shot using 3D technology nominated for Best Picture.

Live-action

The standard for shooting live-action films in 3D involves using two cameras mounted so that their lenses are about as far apart from each other as the average pair of human eyes, recording two separate images for both the left eye and the right eye. In principle, two normal 2D cameras could be put side-to-side but this is problematic in many ways. The only real option is to invest in new stereoscopic cameras. Moreover, some cinematographic tricks that are simple with a 2D camera become impossible when filming in 3D. This means those otherwise cheap tricks need to be replaced by expensive CGI. for example Oz the Great and Powerful. [2]

In 2008, Journey to the Center of the Earth became the first live-action feature film to be shot with the earliest Fusion Camera System released in Digital 3D. This film was later followed with several other films shot in live-action. The 2009 release of Avatar was shot in a 3D process that is based on how the human eye looks at an image. It was an improvement to a currently existing 3D camera system. Many 3D camera rigs still in use simply pair two cameras side by side, while newer rigs are paired with a beam splitter or both camera lens built into one unit. Digital Cinema cameras are not really required for 3D but are the predominant medium 99% of what is photographed. Film options include IMAX 3D and Cine 160.

Animation

Animated films can be rendered as stereoscopic 3D version by using two virtual cameras. Because the entire movie is basically a 3D model, it only takes twice the rendering time and a little effort to properly set up stereoscopic views.

In 2004 The Polar Express was the first stereoscopic 3D animated feature film. In November 2005, Walt Disney Studio Entertainment released Chicken Little in digital 3D format. The first 3D feature by DreamWorks Animation Monsters vs Aliens followed in 2009 and used a new digital rendering process called InTru3D which is a process developed by Intel to create more realistic 3D images despite the fact that they are animated. InTru3D is not a way that films are exhibited in theaters in 3D, the films created in this process are seen in either RealD 3D or IMAX 3D.

Video games

In June 1986, Sega released the Master System, part of the third generation of gaming consoles. The system had a card slot that provided power to a single pair of LCD shutter glasses, allowing certain games to be viewed in 3D; however, only 8 3D-compatible games were ever released, and when the system was redesigned in 1990 in order to cut down on manufacturing costs, it lost the ability to support 3D. It was the first known electronic device released in North America to use LCD shutter glasses.

In July 1995, Nintendo released the Virtual Boy, built around a 3D viewer held closely to users' eyes, acting like a pair of goggles. Both left and right eye images were red, and put strain on players' eyes; the system was a failure and was discontinued the following year. In December 2008, several third-party developers for the PlayStation 3 announced they would work toward bringing Stereoscopic 3D gaming to major gaming consoles using their own technology. In the coming months, both the Xbox 360 and the PlayStation 3 will be capable of 3D imaging via 3D TV and system/hardware updates. On June 15, 2010, at the E3 Expo, Nintendo unveiled the Nintendo 3DS, the successor to the Nintendo DS series of handheld consoles. It is the first gaming console to allow 3D viewing without the need for 3D glasses or an equivalent.

Home media

Television

When the unexpected 3D box office success of Avatar — combined with a record twenty 3D films released in 2009 — produced a presumption among TV manufacturers of heavy consumer demand for 3D television, research and development increased accordingly.

Samsung launched the first 3D TV in February 2010, with the release — via selected retailers — of a 3D starter kit that comprised a Samsung branded 3D-capable High Definition player and television, with two pairs of its 3D glasses, an exclusive 3D edition of Monsters vs. Aliens, along with a discount on the purchase of three other 3D movies. In June 2010, Panasonic announced Coraline and Ice Age: Dawn of the Dinosaurs as bonus 3D titles with the purchase of any of its 3D TVs. On June 22, 2010, Cloudy with a Chance of Meatballs became the first 3D title to be released without any requirement to buy any new electronic hardware, while a free Blu-ray of this Sony title would be included in any of its 3D entertainment packages.

Specifications for 3D included the HDMI 1.4a standards. Some 3D TVs produced simulated 3D effects from standard 2D input, but its effectiveness is limited in the matter of depth.

Each of the TV manufacturers would design its own 3D glasses in accord with its own 3D television technology. Although the only option available in 2010 was active shutter technology, TV manufacturers (notably LG and Vizio) in mid to late 2011 would offer passive circular polarized glasses, while Sony announced a 3D technology ostensibly requiring no 3D glasses at all. In 2015 Samsung unveiled an 8K display with glasses-free 3D — then the largest and highest resolution 3D TV of all. [3]

Home video

Several DVD and Blu-ray releases have already tried their hands at releasing the 3D versions of films by using an anaglyph format. One noted release prior to the advent of digital cinema is the 1982 film Friday the 13th: Part 3 in 3D , but other such films actually shot digitally like Coraline were released on DVD and Blu-ray. Both included 2D and 3D versions and both were packaged with pairs of 3D glasses. The Blu-ray Disc Association ordered a new standard for presenting 3D content on Blu-ray that would also be backwards compatible with all 2D displays. In December 2009, it was announced that they had adopted the Multiview Video Codec, which would be playable in all Blu-ray disc players even if they could not generate a 3D image. The codec contains information that is readable on a 2D output plus additional information that can only be read on a 3D output and display. A future extension for 4K Blu-ray 3D is currently in development for the hevc codec. [4]

Broadcasting

In 2008, the BBC broadcast the world's first live sporting event in 3D, transmitting an England vs. Scotland rugby match to a London cinema. [5] On April 3, 2010, Sky TV broadcast a Chelsea vs. Manchester United match to around 1,000 pubs in the U.K. [6] ESPN 3D launched on June 11, 2010. On July 1, 2010, N3D became the world's first 24-hour 3D channel. 25 matches of in the 2010 FIFA World Cup soccer tournament were broadcast in 3D. [7]

3D films are motion pictures made to give an illusion of three-dimensional solidity, usually with the help of special glasses worn by viewers. They have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business. Nonetheless, 3D films were prominently featured in the 1950s in American cinema, and later experienced a worldwide resurgence in the 1980s and 1990s driven by IMAX high-end theaters and Disney-themed venues. 3D films became increasingly successful throughout the 2000s, peaking with the success of 3D presentations of Avatar in December 2009, after which 3D films again decreased in popularity. Certain directors have also taken more experimental approaches to 3D filmmaking, most notably celebrated auteur Jean-Luc Godard in his film Goodbye to Language.

A 3D display is a display device capable of conveying depth to the viewer. Many 3D displays are stereoscopic displays, which produce a basic 3D effect by means of stereopsis, but can cause eye strain and visual fatigue. Newer 3D displays such as holographic and light field displays produce a more realistic 3D effect by combining stereopsis and accurate focal length for the displayed content. Newer 3D displays in this manner cause less visual fatigue than classical stereoscopic displays.

<span class="mw-page-title-main">Stereo camera</span> Camera with two or more lenses for capturing stereo views

A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera is about the distance between one's eyes and is about 6.35 cm, though a longer base line produces more extreme 3-dimensionality.

The Computer Animation Production System (CAPS) was a proprietary collection of software, scanning camera systems, servers, networked computer workstations, and custom desks developed by The Walt Disney Company and Pixar in the late 1980s. Although outmoded by the mid-2000s, it succeeded in reducing labor costs for ink and paint and post-production processes of traditionally animated feature films produced by Walt Disney Animation Studios (WDAS). It also provided an entirely new palette of digital tools to the animation filmmakers.

<span class="mw-page-title-main">Active shutter 3D system</span> Method of displaying stereoscopic 3D images

An active shutter 3D system is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.

<span class="mw-page-title-main">Anaglyph 3D</span> Method of representing images in 3D

Anaglyph 3D is the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into the perception of a three-dimensional scene or composition.

<span class="mw-page-title-main">Autostereoscopy</span> Any method of displaying stereoscopic images without the use of special headgear or glasses

Autostereoscopy is any method of displaying stereoscopic images without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D". There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: eye-tracking, and multiple views so that the display does not need to sense where the viewer's eyes are located. Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and may include Integral imaging, but notably do not include volumetric display or holographic displays.

RealD 3D is a digital stereoscopic projection technology made and sold by RealD. It is currently the most widely used technology for watching 3D films in theaters. Worldwide, RealD 3D is installed in more than 26,500 auditoriums by approximately 1,200 exhibitors in 72 countries as of June 2015.

<span class="mw-page-title-main">Parallax barrier</span> 3D imaging device

A parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic or multiscopic image without the need for the viewer to wear 3D glasses. Placed in front of the normal LCD, it consists of an opaque layer with a series of precisely spaced slits, allowing each eye to see a different set of pixels, so creating a sense of depth through parallax in an effect similar to what lenticular printing produces for printed products and lenticular lenses for other displays. A disadvantage of the method in its simplest form is that the viewer must be positioned in a well-defined spot to experience the 3D effect. However, recent versions of this technology have addressed this issue by using face-tracking to adjust the relative positions of the pixels and barrier slits according to the location of the user's eyes, allowing the user to experience the 3D from a wide range of positions. Another disadvantage is that the horizontal pixel count viewable by each eye is halved, reducing the overall horizontal resolution of the image.

<i>Monsters vs. Aliens</i> 2009 film by Conrad Vernon and Rob Letterman

Monsters vs. Aliens is a 2009 American animated science fiction action comedy film produced by DreamWorks Animation and distributed by Paramount Pictures. The film was directed by Conrad Vernon and Rob Letterman from a screenplay written by Letterman, Maya Forbes, Wallace Wolodarsky, and the writing team of Jonathan Aibel and Glenn Berger based on a story by Vernon and Letterman. Featuring the voices of Reese Witherspoon, Seth Rogen, Hugh Laurie, Will Arnett, Kiefer Sutherland, Rainn Wilson, Paul Rudd, and Stephen Colbert, the film involves a group of misfit monsters hired by the United States Armed Forces to stop the invasion of an extraterrestrial villain and save the world in exchange for freedom.

TDVision Systems, Inc., was a company that designed products and system architectures for stereoscopic video coding, stereoscopic video games, and head mounted displays. The company was founded by Manuel Gutierrez Novelo and Isidoro Pessah in Mexico in 2001 and moved to the United States in 2004.

<span class="mw-page-title-main">3D television</span> Television that conveys depth perception to the viewer

3D television (3DTV) is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. As of 2017, most 3D TV sets and services are no longer available from manufacturers.

3ality Technica, formerly 3ality Digital, was a Burbank, California based company that specialized in high-definition, live-action stereoscopic digital 3D. The company developed production systems, image processing software and other technologies that enabled the creation, post-production and distribution of live-action 3D entertainment.

The Fujifilm FinePix Real 3D W series is a line of consumer-grade digital cameras designed to capture stereoscopic images that recreate the perception of 3D depth, having both still and video formats while retaining standard 2D still image and video modes. The cameras feature a pair of lenses, and an autostereoscopic display which directs pixels of the two offset images to the user's left and right eyes simultaneously. Methods are included for extending or contracting the stereoscopic baseline, albeit with an asynchronous timer or manually depressing the shutter twice. The dual-lens architecture also enables novel modes such as simultaneous near and far zoom capture of a 2D image. The remainder of the camera is similar to other compact digital cameras.
