3-D film

From Wikipedia, the free encyclopedia

In film, the term 3-D (or 3D) is used to describe any visual presentation system that attempts to maintain or recreate moving images of the third dimension, the illusion of depth as seen by the viewer.

The principle involves taking two images simultaneously, with two cameras positioned side by side, generally facing each other and filming at a 90 degree angle via mirrors, in perfect synchronization and with identical technical characteristics. When viewed in such a way that each eye sees its photographed counterpart, the viewer's visual cortex will interpret the pair of images as a single three-dimensional image. See stereoscopy for a more detailed description.

[edit] Techniques

There are several methods of projecting natural, steroscopic images.

• Anaglyphic
• Polarization
• Alternate-frame sequencing

Furthermore, alternative systems, such as Pulfrich effect exist, but fall under the realm of "pseudo-stereoscopic" in that two, separate records are not recorded or projected.

In the context of many computer games, 3D computer graphics refer to being composed of objects in a virtual 3-D world, not that they can be viewed in 3-D. For a stereoscopic 3-D games, as for everything else stereoscopic, two pictures (one for each eye), are needed.

[edit] History

[edit] Early patents and tests

The stereoscopic era of motion pictures begins in the late 1890s when British film pioneer William Friese-Greene files a patent for a 3-D movie process. In his patent, two films are projected side by side on screen. The viewer looked through a stereoscope to converge the two images. Because of the obtrusive mechanics behind this method, theatrical use was not practical.^[1]

Frederick Eugene Ives patented his stereo camera rig in 1900. The camera had two lenses coupled together 1 3/4 inches apart^[2].

On June 10, 1915, Edwin S. Porter and William E. Waddell presented tests to an audience at the Astor Theater in New York City. In red/green anaglyph, the audience was presented 3 reels of tests, which included rural scenes, test shots of Marie Doro, a segment of John Mason playing a number of passages from Jim the Penman (a film released by Famous Players-Lasky that year, but not in 3-D), Oriental dancers, and a reel of footage of Niagara Falls. ^[3] However, according to Adolph Zukor in his 1953 autobiography The Public Is Never Wrong: My 50 Years in the Motion Picture Industry, nothing was produced in this process after these tests.

[edit] Early systems of stereoscopic filmmaking (pre-1952)

The earliest confirmed 3-D film shown to a paying audience was The Power of Love, which premiered at the Ambassador Hotel Theater in Los Angeles on September 27, 1922. The camera rig was a product of the film's producer, Harry K. Fairall, and cinematographer Robert F. Elder.^[1] It was projected dual-strip in the red/green anaglyph format, making it both the earliest known film that utilized dual strip projection and the earliest known film in which anaglyph glasses were used.^[4] Whether Fairall used colored filters on the projection ports or whether he used tinted prints is unknown, but it is the first documented instance of dual-strip projection. After a preview for exhibitors and press in New York City, the film dropped out of sight, apparently not booked by exhibitors, and is now considered lost.

Early in December 1922, William Van Doren Kelley cashed in on the growing interest in 3-D films started by Fairall's demonstration and shot footage with a camera system of his own design. Kelley then struck a deal with Samuel "Roxy" Rothafel to premiere the first in his series of "Plasticon" shorts entitled Movies of the Future at the Rivoli Theater in New York City .^[5]

Kelley, who was primarily a producer of color films, used his color system, Prizma, to print his anaglyph films. In early 1923, he shopped around a second Plasticon entitled Through the Trees - Washington D.C., shot by William T. Crespinel, which consisted of stereoscopic views of Washington, D.C., but found no buyers. ^{[citation needed]}

Also in December 1922, Laurens Hammond (later inventor of the Hammond organ) and William F. Cassidy unveiled their Teleview system. Teleview was the earliest alternate-frame sequencing form of projection. Through the use of two interlocked projectors, alternating left/right frames were projected one after another in rapid succession. Synchronized viewers attached to the arm-rests of the seats in the theater open and closed at the same time, and took advantage of the viewer's persistence of vision, thereby creating a true stereoscopic image. The only theater known to have installed this system was the Selwyn Theater in New York. Only one show was ever produced for the system, a groups of shorts and the only Teleview feature The Man From M.A.R.S. (later re-released as Radio-Mania) on 27 December 1922 in New York City.^[6]

In 1923, Frederick Eugene Ives and Jacob Leventhal began releasing their first stereoscopic shorts made over a three-year period. The first film entitled, Plastigrams, which was distributed nationally by Educational Pictures in the red/blue anaglyph format. Ives and Leventhal then went on to produce the following stereoscopic shorts in the "Stereoscopiks Series" for Pathé Films in 1925: Zowie (April 10), Luna-cy (May 18), The Run-Away Taxi (December 17) and Ouch (December 17). ^[7]

The late 1920s to early 1930s saw little to no interest in stereoscopic pictures, largely due to the Great Depression. In Paris, Louis Lumiere shot footage with his stereoscopic camera in September of 1933. The following year, in March 1934, he premiered his remake of his 1895 film L'Arrivée du Train, this time in anaglyphic 3-D.

In 1936, Leventhal and John Norling were hired based on their test footage to film MGM's Audioscopiks series. The prints were by Technicolor in the red/green anaglyph format, and were narrated by Pete Smith. The first film, Audioscopiks, premiered January 11, 1936 and The New Audioscopiks premiered January 15, 1938. Audioscopiks was nominated for the Academy Award for Short Film - Novelty in 1936.

With the success of the two Audioscopiks films, MGM produced one more short in anaglyph 3-D, another Pete Smith Specialty called Third Dimensional Murder (1941). Unlike its predecessors, this short was shot with a studio-built camera rig. Prints were by Technicolor in red/blue anaglyph. The short is notable for being the first live-action appearance of the Frankenstein Monster as conceived by Jack Pierce for Universal Studios outside of their company.

While many of these films were printed by color systems, it should be noted that none of them was actually in color, and the use of the color printing was only to achieve an anaglyph effect.

[edit] Introduction of Polaroid

While attending Harvard University in 1926, Edwin H. Land conceived the idea of reducing glare by polarizing light. He took a leave of absence from Harvard to set up a lab and by 1929 had invented and patented a polarizing sheet.^[8] In 1932, he introduced Polaroid J Sheet as a commercial product.^[9] While his original intention was to create a filter for reducing glare from car headlights, Land did not underestimate the utility of his newly dubbed Polaroid filters in stereoscopic presentations.

In January 1936, Land gave the first demonstration of Polaroid filters in conjunction with 3-D photography at the Waldorf-Astoria Hotel.^{[citation needed]} The reaction was enthustiastic, and he followed it up with an installation at the New York Museum of Science.^{[citation needed]} It is unknown what film was run for audiences with this installation.

Using Polaroid filters meant an entirely new set-up, however. Two prints, each carrying either the right or left eye, had to be synced up in projection using an external selsyn motor. Furthermore, polarized light would not register on a matte white screen, and only a silver screen or screen made of other reflective material would correctly reflect the separate images.

Later that year, the feature, Nozze Vagabonde appeared in Italy^{[citation needed]}, followed by the first color 3-D feature, Zum Greifen Nah which premiered in Germany the following year^{[citation needed]}. It is unknown whether or not these films took advantage of the Polaroid filter system in projection, but the possibility is present.

In 1939, John Norling shot In Tune With Tomorrow, the first polaroid 3-D film shown for a paying audience in the US^{[citation needed]}. This short premiered at the 1939 New York World's Fair and was created specifically for the Chrysler Motor Pavillion. In it, a full 1939 Chrysler Plymouth is magically put together, set to music. Originally in black and white, the film was so popular that it was re-shot in color for the following year at the fair, under the title New Dimensions^{[citation needed]}. In 1953, it was reissued by RKO as Motor Rhythm.

Another early short that utilized the Polaroid 3-D process was 1940's Magic Movies: Thrills For You produced by the Pennsylvania Railroad Co. for the Golden Gate International Exposition ^{[citation needed]}. Produced by John Norling, it was actually shot for him by Jacob Leventhal using his own rig. It consisted of shots of various views that could be seen on Pensylvannia Railroad's trains.

The 1940s was further hindered by World War II, and stereoscopic photography once again went on the back-burner in most producers' minds.

[edit] The "golden era" (1952-1955)

What aficionados consider the "golden era" of 3-D began in 1952 with the release of the first color stereoscopic feature, Bwana Devil, produced, written and directed by Arch Oboler. The film was shot in Natural Vision, a process that was co-created and controlled by M. L. Gunzberg. Gunzberg, who built the rig with his brother, Julian, and two other associates, shopped it without success to various studios before Oboler used it for this feature, which went into production with the title, The Lions of Gulu.^{[citation needed]} The film stars Robert Stack, Barbara Britton and Nigel Bruce.

As with practically all of the features made during this boom, Bwana Devil was projected dual-strip, with polaroid filters. During the 1950s, the familiar disposable anaglyph glasses made of cardboard were mainly used for comic books, two shorts by Dan Sonny Productions, and three shorts produced by Lippert Productions. One should note, however, that even the Lippert shorts were available in the dual-strip format alternatively.

Because the features utilized two projectors, a capacity limit of film being loaded onto each projector (about 6,000 feet) meant that an intermission was necessary for every movie. Quite often, intermission points were written into the script of the film at a major plot point.

During Christmas of 1952, producer Sol Lesser quickly premiered the dual-strip showcase called Stereo Techniques in Chicago.^{[citation needed]} Lesser acquired the rights to five dual strip shorts. Two of them, Now is the Time (to Put On Your Glasses) and Around is Around, were directed by Norman McLaren in 1951 for the National Film Board of Canada. The other three films were produced in Britain for Festival of Britain in 1951 by Raymond Spottiswoode. These were A Solid Explanation, Royal River, and The Black Swan.

James Mage was also an early pioneer in the 3-D craze. Using his 16mm 3-D Bolex system, he premiered his Triorama program on February 10, 1953 with his four shorts: Sunday In Stereo, Indian Summer, American Life, and This is Bolex Stereo^{[citation needed]}. This show is considered lost.

Another early 3-D film during the boom was the Lippert Productions short, A Day in the Country, narrated by Joe Besser and comprised of mostly test footage. Unlike all of the other Lippert shorts, which were available in both dual-strip and anaglyph, this production was released anaglyph only.

April of 1953 saw two groundbreaking features in 3-D: Columbia's Man In the Dark and Warner Bros. House of Wax, the first 3-D feature with stereophonic sound. House of Wax, outside of Cinerama, was the first time many American audiences heard recorded stereophonic sound. It was also the film that typecast Vincent Price as a horror star as well as the "King of 3-D" after he became the actor to star in the most 3-D features (the others were The Mad Magician, Dangerous Mission, and Son of Sinbad). The success of these two films proved that major studios now had a method of getting moviegoers back into theaters and away from television sets, which were causing a steady decline in attendance.

The Walt Disney Studios waded into 3-D with its May 28, 1953 release of Melody, which accompanied the first 3-D western, Columbia's Fort Ti at its Los Angeles opening. It was later shown at Disneyland's Fantasyland Theater in 1957 as part of a program with Disney's other short Working For Peanuts, entitled, 3-D Jamboree. The show was hosted by the Mousketeers and was in color.

Universal-International released their first 3-D feature on May 27, 1953, It Came from Outer Space, with stereophonic sound. Following that was Paramount's first feature, Sangaree with Fernando Lamas and Arlene Dahl.

Columbia, aside from many 3-D westerns produced by Sam Katzman and directed by William Castle, released two 3-D shorts with the Three Stooges in 1953: Spooks and Pardon My Backfire. Their last short subject filmed in 3-D was Down the Hatch with comedian Harry Mimmo. Released later, the short was issued flat.

John Ireland, Joanne Dru and Macdonald Carey starred in the Jack Broder color production Hannah Lee, which premiered June 19, 1953. The film was directed by Ireland, who sued Broder for his salary. Broder countersued, claiming that Ireland went over production costs with the film.^{[citation needed]}

Another famous entry in the golden era of 3-D was the 3 Dimensional Pictures production of Robot Monster. The film was allegedly scribed in an hour by screenwriter Wyott Ordung and filmed in a period of two weeks on a shoestring budget.^{[citation needed]} Despite these shortcomings and the fact that the crew had no previous experience with the newly-built camera rig, luck was on the cinematographer's side, as many find the 3-D photography in the film is well shot and aligned. Robot Monster also has a notable score by then up-and-coming composer, Elmer Bernstein. The film was released June 24, 1953 and went out with the short Stardust in Your Eyes, which starred nightclub comedian, Slick Slavin.^{[citation needed]}20th Century Fox produced their only 3-D feature, Inferno, starring Rhonda Fleming. Fleming, who also starred in Those Redheads from Seatte, and Jivaro, shares the spot for being the actress to appear in the most 3-D features with Patricia Medina, who starred in Sangaree, Phantom of the Rue Morgue and Drums of Tahiti. Darryl F. Zanuck expressed little interest in stereoscopic systems, and at that point was preparing to premiere the new film system, CinemaScope.

The first decline in the theatrical 3-D craze started in the late summer/early fall of 1953. The factors causing this decline were:

• Two prints had to be projected simultaneously.
• The prints had to remain exactly alike after repair, or synchronization would be lost.
• It sometimes required two projectionists to keep sync working properly.
• When either prints or shutters became out of sync, the picture became virtually unwatchable and accounted for headaches and eye strain.
• The necessary silver projection screen was very directional and caused sideline seating to be unusable with both 3-D and regular films, due to the angular darkening of these screens. Later films that opened in wider-seated venues often premiered flat for that reason (such at Kiss Me Kate at the Radio City Music Hall).

Because projection booth operators were at many times careless, even at preview screenings of 3-D films, trade and newspaper critics claimed that certain films were "hard on the eyes."^{[citation needed]}

Sol Lesser attempted to follow up Stereo Techniques with a new showcase, this time five shorts that he himself produced.^{[citation needed]} The project was to be called The 3-D Follies and was to be distributed by RKO.^{[citation needed]} Unfortunately, because of financial difficulties and the growing disinterest in 3-D, Lesser cancelled the project during the summer of 1953, making it the first 3-D film to be aborted in production.^{[citation needed]} Two of the three shorts were shot: Carmenesque, a burlesque dance number starring Lili St. Cyr and Fun in the Sun, a daytime sport short directed by famed set designer/director William Cameron Menzies, who also directed in the 3-D feature, The Maze for Allied Artists.

Although it was more expensive to install, the major competing realism process was anamorphic widescreen, first utilized by Fox with Cinemascope and its September premiere in The Robe. Anamorphic widescreen features needed only a single print, so synchronization was not an issue. Cinerama was also a competitor from the start and had better quality control than 3-D because it was owned by one company that focussed on quality control. However, most of the 3-D features past the summer of 1953 were released in the flat widescreen formats ranging from 1.66:1 to 1.85:1. It should be noted that in early studio advertisements and articles about widescreen and 3-D formats, widescreen systems were being referred to as "3-D," causing some confusion among scholars.

There was no single instance of combining Cinemascope with 3-D until 1960, with a film called September Storm, and even then, that was a blow-up from a non-anamorphic negative.^{[citation needed]} September Storm also went out with the last dual-strip short, Space Attack, which was actually shot in 1954 under the title The Adventures of Sam Space.

In December 1953, 3-D made a comeback with the release of several important 3-D films, including MGM's musical Kiss Me, Kate. Kate was the hill which 3-D had to pass over to survive. MGM tested it in six theaters: three in 3-D and three flat.^{[citation needed]} The 3-D version was so well-received that the film quickly went into a wide stereoscopic release.^{[citation needed]} Contrary to published opinion that stated the film played most theaters flat, the release was so popular that the demand for the 3-D version caused a surplus order of Technicolor dual-strip prints.^{[citation needed]} The film, based on the popular Samuel and Bella Spewack musical, was one of MGM's "Lucky 7" films of the year,^{[citation needed]} and starred the MGM songbird team of Howard Keel and Kathryn Grayson as the leads, supported by Ann Miller, Keenan Wynn, Bobby Van, James Whitmore, Kurt Kasznar and Tommy Rall. The film also prominently promoted its use of stereophonic sound.

Several other features that helped put 3-D back on the map that month were the John Wayne feature Hondo (distributed by Warner Bros.), Columbia's Miss Sadie Thompson with Rita Hayworth, and Paramount's Money From Home with Dean Martin and Jerry Lewis. Paramount also released the cartoon shorts Boo Moon with Casper, the Friendly Ghost and Popeye, Ace of Space with Popeye the Sailor.

Top Banana, based on the popular stage musical with Phil Silvers, was brought to the screen with the original cast. Although it was merely a filmed stage production, the idea was that every audience member would feel they would have the best seat in the house through color photography and 3-D.^{[citation needed]} Although the film was shot and edited in 3-D, United Artists, the distributor, felt the production was uneconomical in stereoscopic form and released the film flat on January 27, 1954.^{[citation needed]} It remains one of two "Golden era" features, along with another United Artists feature, Southwest Passage (with John Ireland and Joanne Dru), that are currently considered lost.

A string of successful 3-D movies followed the second wave. Some highlights are:

• The French Line, starring Jane Russell and Gilbert Roland, a Howard Hughes/RKO production. The film became infamous for being released without an MPAA seal of approval, after several suggestive lyrics were included, as well as one of Ms. Russell's particularly revealing costumes.^{[citation needed]} Playing up her sex appeal, one tagline for the film was, "It'll knock both of your eyes out!" The film was later cut and approved by the MPAA for a general flat release, despite having a wide and profitable 3-D release.^{[citation needed]}

• Taza, Son of Cochise, which starred Rock Hudson in the title role, Barbara Rush as the love interest, and Rex Reason (billed as Bart Roberts) as his renegade brother, released through Universal-International.

• Two ape films: Phantom of the Rue Morgue, featuring Karl Malden and Patricia Medina, and produced by Warner Bros. and based on Edgar Allan Poe's Murders in the Rue Morgue, and Gorilla At Large, a Panoramic Production starring Cameron Mitchell, distributed through Fox.

• Creature From The Black Lagoon, starring Richard Carlson and Julie Adams, directed by Jack Arnold. Arguably the most famous 3-D movie, and the only 3-D feature that spawned a sequel, Revenge of the Creature in 3-D (followed by another sequel, The Creature Walks Among Us, shot flat).

• Cat-Women of the Moon, an Astor Picture starring Victor Jory and Marie Windsor. Elmer Bernstein composed the score.

• Dial M for Murder, directed by Alfred Hitchcock and starring Ray Milland, Robert Cummings, and Grace Kelly, is considered by aficionados of 3-D to be one of the best examples of the process. Although available in 3-D in 1954, there are no known playdates in 3-D, since Warner Bros. had just instated a simultaneous 3-D/2-D release policy. The film's screening in 3-D in February 1980 at the York Theater in San Francisco did so well that Warner Bros. re-released the film in 3-D in February 1982.

• Gog, an Ivan Tors production, dealing with realistic science fiction. The second film in Tors' "Office of Scientific Investigation" trilogy of film, which included, The Magnetic Monster and Riders to the Stars.

• The Diamond Wizard, the only stereoscopic feature shot in Britain, released flat in both the UK and US. It starred and was directed by Dennis O'Keefe.

• Son of Sinbad, another RKO/Howard Hughes production, starring Dale Robertson, Lili St. Cyr, and Vincent Price. The film was shelved after Hughes ran into difficulty with The French Line, and wasn't released until 1955, at which time it went out flat, converted to the SuperScope process.

3-D's final decline was in the late spring of 1954, for the same reasons as the previous lull, as well as the further success of widescreen formats with theater operators. Even though Polaroid had created a well-designed "Tell-Tale Filter Kit" for the purpose of recognizing and adjusting out of sync and phase 3-D,^{[citation needed]} exhibitors still felt uncomfortable with the system and turned their focus instead to processes such as CinemaScope. The last 3-D feature to be released in that format during the "Golden era" was Revenge of the Creature, on February 23, 1955. Ironically, the film had a wide release in 3-D and was well received at the Box Office.^{[citation needed]}

[edit] Revival (1960-1979)

Stereoscopic films largely remained dormant for the first part of the 1960s, with those that were released usually being anaglyph exploitation films. One film of notoriety was the Beaver-Champion/Warner Bros. production, The Mask (1961). The film was shot in 2-D, but to enhance the bizarre qualities of the dream-world that is induced when the main character puts on a cursed tribal mask, the film went to anaglyph 3-D. These scenes were printed by Technicolor on their first run in red/green anaglyph.

Although 3-D films appeared sparsely during the ealy 1960s, the true second wave of 3-D cinema was set into motion with the same producer who started the craze of the 1950s. Using a new technology called Space-Vision 3D, stereoscopic films were printed with two images on top of one another in a single academy ratio frame on a single strip, and needed only one projector fitted with a special lens. This so-called "over and under" technique eliminated the need for dual projector set-ups, and produced widescreen polaroid 3-D images.

Arch Oboler once again had the vision for the system that no one else would touch, and put it to use on his film entitled The Bubble, which starred Michael Cole, Deborah Walley, and Johnny Desmond. As with Bwana Devil, the critics panned The Bubble, but audiences flocked to see it, and it became financially sound enough to promote the use of the system to other studios, particularly independents, who did not have the money for expensive dual-strip prints of their productions.

In 1970, Stereovision developed a different single-strip format, which printed two images squeezed side-by-side and used an anamorphic lens to widen the pictures through polaroid filters. Louis K. Sher (Sherpix) and Stereovision released the softcore sex comedy The Stewardesses (self-rated X, but later re-rated R by the MPAA). The film cost $100,000 USD to produce,^{[citation needed]} but earned $27 million ($110 million in constant-2006 dollars) in fewer than 800 theaters, becoming the most profitable 3-Dimensional film to date. It was later released in 70mm 3-D.^{[citation needed]} Some 36 films world-wide were made with Stereovision over 25 years, using either a widescreen (above-below) or the anamorphic (side by side) format or 70mm 3-D.

The quality of the following 3-D films were not much more inventive, as many were either softcore and even hardcore adult films, horror films, or a combination of both. Paul Morrisey's Flesh For Frankenstein (aka Andy Warhol's Frankenstein) was a superlative example of such a combination.

[edit] The revival's apex (1980-1984)

In the early 1980s, IMAX (Large format-sideways running, 70mm) began offering non-fiction films in 3-D, and fiction starting with the 45-minute Wings of Courage (1995), by director Jean-Jacques Annaud, about the author and pilot Antoine de Saint-Exupéry.

Using the over-under process pioneered by SpaceVision, Hollywood's film-makers hit a craze comparable to that of the one thirty years previous. With the popularity of StereoVision re-issues of House of Wax and Dial M For Murder, newly inspired directors jumped the bandwagon in creating 3-D films geared towards newer, mainstream audiences. Some of these included:

• Amityville 3-D
• Comin' at Ya!
• Treasure of the Four Crowns
• Friday the 13th Part 3
• Jaws 3-D
• Metalstorm: The Destruction of Jared-Syn
• Parasite
• Silent Madness

[edit] 3-D formats (1984-Present)

In 2003, James Cameron's Ghosts of the Abyss was released as the first full-length 3-D IMAX feature filmed with the Reality Camera System. This camera system used the latest HDTV video cameras, not film, and was built for Cameron to his specifications. The same camera system was used to film Spy Kids 3D: Game Over (2003), Aliens of the Deep IMAX (2005), and The Adventures of Sharkboy and Lavagirl in 3-D (2005).

In November 2004, Polar Express was released as IMAX's full-length, animated 3-D feature. It was released in over 3,550 theaters in 2D, and only 62 IMAX locations. The return from those few 3-D theaters was about 25% of the total. The 3-D version earned about 14 times as much per screen than the 2D version. This has prompted a greatly intensified interest in 3-D and 3-D presentation of animated films.

In November 2005, Walt Disney Studio Entertainment released Chicken Little, in the new digital 3-D format known as REAL D, utilizing one digital projector alternating clockwise and counterclockwise polarized images at 144 frames per second. Glasses are worn that diffuse each circular polarization for one of the eyes so that a 3-D effect is achieved. The use of circular polarization improves on the older technique of linear polarization in that there is no ghosting or leakage and the viewers can tilt their head without affecting the 3-D effects. Following the successful financial gross of the film, further animated films in 3-D have been announced as in production and to be ready by December 2006 in both the IMAX 3-D film format as well as Digital 3-D. Disney also announced that they hope to have 750 Digital 3-D installations in place for their fall 2006 3-D release, Meet the Robinsons.

The 3D technology currently used worldwide is based on the methods and inventions of Félix Bodrossy, who did not patent his methods, as these are still considered the most up-to-date. (Source in Hungarian, reference in Dutch)

[edit] The World 3-D Exposition

In September 2003, Sabucat Productions organized the first World 3-D Exposition, celebrating the 50th anniversary of the original craze. The Expo was held at Grauman's Egyptian Theatre. During the two-week festival, over 30 of the 50 "golden era" stereoscopic features (as well as shorts) were screened, many coming from the collection of film historian and archivist Robert Furmanek, who had spent the previous 15 years painstakingly tracking down and preserving each film to its original glory. In attendance were many stars from each film, respectively, and some were moved to tears by the sold-out seating with audiences of film buffs from all over the world who came to remember their previous glories.

In May 2006, the second World 3-D Exposition was announced for September of that year. Along with the favorites of the previous exposition were newly discovered features and shorts, and like the previous Expo, guests from each film. Expo II was announced as being the local for the world premiere of several films never before seen in 3-D, including The Diamond Wizard and the Universal short, Hawaiian Nights with Mamie Van Doren and Pinky Lee. Other "re-premieres" of films not seen since their original release in stereoscopic form included Cease Fire!, Taza, Son of Cochise, Wings of the Hawk, and Those Redheads From Seattle. Also shown were the long-lost shorts Carmenesque and A Day in the Country (both 1953) and William Van Doren Kelley's two Plasticon shorts (1922 and 1923).

[edit] New developments (2006)

Through the entire history of 3D presentations, techniques to convert existing 2D images for 3D presentation have existed. Few have been effective or survived. The combination of digital and digitized source material with relatively cost effective digital post processing has spawned a new wave of conversion products. In June 2006, IMAX and Warner Brothers released Superman Returns including 20 minutes of 3-D images converted from the 2-D original digital footage. George Lucas has announced that he may re-release his Star Wars films in 3-D based on a conversion process from the company In-Three.

James Cameron (Titanic) intends to shoot his new films Avatar and Battle Angel in digital 3-D. Filming will use HDTV cameras and the Fusion Camera system.

Animated films Open Season, and The Ant Bully, were released in IMAX 3D in 2006. Monster House and The Nightmare Before Christmas were released in REAL D Cinema digital 3D in 2006.

In late 2005 Steven Spielberg told the press he was involved in patenting a 3-D cinema system that does not need glasses, and which is based on plasma screens. A computer splits each film-frame, and then projects the two split images onto the screen at differing angles, to be picked up by tiny angled ridges on the screen. (Spielberg is co-producer of the film Monster House but the potential process was not used for the current release of Monster House.)

[edit] 3-D TV

Philips is also developing a flat TV screen where it is possible to watch 3D films without glasses, as mentioned in this article.

The development of 3-D television represents a new generation of TV that will be available for home use in the future. Presently this kind of TV is rare and is used primarily for advertisements.
