3D Televisions


There are many innovations in the world of technology and one popular, unusual visualization experience is called 3D. 3D (three dimensional) viewing,
also known as stereoscopic viewing is a visualization that allows someone to see objects in the third dimension. The use of this vision is used on television
and computer design. This imagery allows a person to feel like the object they are watching is truly alive. Today 3D is most popular in Movies at theatres or at home on a DVD.
Technology in our generation has become so advanced. Companies are always coming out with something new. The new T.V. in the industry is the 3D television. This TV includes a great picture for viewers to enhance the visual experience. With each television anaglyph color glasses are needed to see the 3D experience in action. This new device is hot on the market and is a competitive product for the companies.
The first 3D TV is the Flat Panel television. This device uses LCD or plasma technology. It is a thin and sleek high definition TV. The flat panel TV is one of the most common used TV with great display. This television uses 720p if 40 inches or under and 1080p if larger. The flat panel is the television to use when someone is looking for great life-like vision and nice sound.


Terminology Associated with 3D


3D graphics are made by 3D graphic accelerators that can draw polygons, using only the polygons 3-dimensonal vertices, which can map textures on polygons or shade textures. Alpha-blending is a technique used in transparency and it adds extra value to the pixels of a texture of a map to make the objects and effects look as realistic as possible. An alpha channel includes the colors Red, Green, and Blue and can be used to create a whole range of different colors. The 3D effect is also achieved through depth cueing, which changes the color and hue of an object in accordance with the object’s distance from the viewer. A term that refers to the entire process of creating a 3D image is called rendering. One of the most important parts of 3D is the Z-Axis. The Z-Axis measures the depth of an object in the 3D world. By using only the X-axis and the Y-axis the object would be 2D, but the Z-Axis enables the image to have depth and become 3D.

Specifications

For 3D are the glasses and the display,screen. Their purpose is to feed different images into your eyes. The screen displays 2 images. The glasses causes one of the images to go into one eye, then the second image goes into the other eye. There are two types of glasses; there is the red/blue and the polarization. Red and blue glasses do the same exact purpose. Two images displays on the screen, one in red, the other in blue/green. The filters allow one image to enter each eye. It filters the 2 projected images allowing only one image entering each eye. The polarization glasses are mostly used at Disney World and Universal Studios. Two synchronized projectors project respective views onto the screen with each of a different polarization. The glasses allow only of the images into each eye because they have lenses with different polarization. There are more systems but they are really complicated and expensive. As a result of being complicated and expensive, they are not widely used. An example is the LCD glasses, they block the view of each eye and then the other is the rapid succession. This system allows color viewing as the normal TV, but it requires special equipment. The 3D display, the screen, is able of passing on the 3D images to the viewer. There are four types of displays, there is the Stereoscopic, autostereoscopic, and computer generated holography and volumetric displays. The stereoscopic is a separate device for each person in the room, which provides a unlike image to the person’s left and right eye. The autostereoscopic display allows the viewer to move his/her head without destroying the illusion of the deepness. The computer generated holography is able to make a light field exact same to what is from the original screen. The volumetric display uses voxels instead of pixels. Voxels are the volume element. It uses a regular grid in the 3D space. These displays have problem depending where the viewer is sitting, the equipment that is hard to get, or the high cost.

History of 3D


stereoscope.jpg
3-D technology, or stereoscopy started in the 1800s. In 1838, Sir Charles Wheatstone invented the first form of 3-D glasses. The model has stayed the same with only a few adjustments. It began with the stereoscope (pictured left), which enables you to see images as 3-D by putting on a type of glasses. The stereoscope was the first form of the glasses we use today. With the stereoscope, you had to focus the image until it was in 3-D. The growth of the stereoscope started when Queen Victoria took an interest in it at the London Crystal Palace in 1951.

Three dimensional imaging or stereoscopy was brought about by stereoscopic imaging which is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image.In 1894, William Friese-Green created a 3D viewing process which used two separate screens. The viewer would wear a large headset that would unite the two screens and create the 3D image. From 1900 to 1950, many people experimented with ideas of 3D viewing.
Edwin Porter ran tests using anaglyphs. Anaglyphs use one projected image, but each eye has a different color filter. This creates a different picture from each eye’s perspec3D_Glasses_image_-_movie_theater.jpgtive to make the image appear 3D. In Los Angeles, California in 1920, Robert Elder developed a movie called “The Power of Love,” which became the first ever 3D movie to be publicly shown. Then in 1922, Laurens Hammond and William Cassidy developed a movie in 3D. It used two specialized projectors and headsets and could only be screened in the theater in which it was originally set up. In 1923, Frederick Ives and Joseph Levanthal developed a series of short films in 3D.
1930s, William Gruber invented a way to see 3-D with a 35mm film. In the 1950s, 3D started to become more popular.

Many movies and short films were cast. The very first feature-length movie was “Bwana Devil”, made in 1952. The biggest obstacle on 3D’s path to success though, was that 3D required large amounts of expensive and highly complex equipment, and it did not even produce a good picture. Because of this 3D began to fade. Then in the 1970s, producers tried to bring 3D back. Many films began to be developed in 3D. Audiences loved it, but again, 3D faded. From 1985 to 2000, the evolution of
IMAX (Image Maximum) led to IMAX 3D. Now with IMAX to add to it, 3D became a huge hit and flourished. In the recent past, 3D has come into computers and home theaters, even newer everyday televisions.

Current Uses of 3D


Film dino.jpg

3D film is a motion picture that enhances the illusion of depth perception. An extraordinary motion camera records the images as seen from two perspectives, and it shows special projection hardware and eyewear that are used to provide the illusion of depth while watching the film. 3D film is becoming more popular every day.

Computer Graphics

3D computer graphics are graphics that use a three-dimensional demonstration of geometric data that is stored in the computer for performing calculations and describing 2D images. 3D computer graphics are often referred to as 3D models. A 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is visually displayed.

Printing

3D printing is another use of 3D in our society. It uses a printing technology called Fused Deposition Modeling (FDM). This printing is a form of preservative manufacturing technology where a three-dimensional object is created by continuous layers of material. 3D printers are generally faster, cheaper, and simpler to function than other manufactured printers. They offer developers the capability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build.

Real Estate

3D visualizations are used in real estate all across the country. This process is used to sell homes. The visualizations must be appealing and accurate in order for the home to be sold. These visualizations, in 3D, allow the potential buyers to view the home, even if the home is in the process of construction. This process can be used for all formteets.gifs of residential housing: townhomes, condominiums, apartments, and houses. The visualization is taken from the floor plan, up. With the 3D visualization the floor plan gives an outline to the property. This process is very beneficial to real estate developers and potential buyers.

Medical Field

3D modeling is the most common form of 3D models that are apparent in the medical field. This software allows the user to input specific information and measurements to change, form, and model the shape within the software program. From this point, measurements will be taken of the patient. Then specific body parts in proportion to others will be implemented into the computer, allowing for an accurate 3D model of the patient’s body part.

How Does 3D Work



With the new Blu-ray standard for high-definition 3-D, Panasonic, Sony and Samsung are all releasing home-theater setups that can display 3-D movies in full high-definition. Using a combo of 3-D-capable Blu-ray players, TVs and glasses, the systems are able to deliver separate, full-screen, 1080p pictures to each eye. The technique they use creates a picture as vivid as in a movie theater without requiring a major overhaul of TV technology. And within a few years, a new cable television standard could even bring events like the Super Bowl right to your TV in high-def 3-D.

Blu-ray discs have plenty of room to store a separate 1080p signal for each eye, as well as the coding necessary to specify which image is meant for the left side and which for the right. 3-D-ready players use a special chip to interpret this info and send it to a 3-D-capable TV.

The TV

We see depth when images from our left and right eyes merge into one; to re-create that in high-def, TVs must refresh the picture at least 120 times a second with alternating frames for the left and right eye, which tricks your brain into seeing only one image. Most new TVs are fast enough to do this, but to be 3-D-capable, TVs must include a converter chip and software to break down the signal and separate the left and right images. An infrared or radio beam syncs shutter glasses with the screen to produce the final 3-D effect.

3D Glasses

3-d-glasses-traditional.gif
In order to see things in 3D each eye must see a slightly different picture. This is done in the real world by your eyes being spaced apart so each eye has its own slightly different view. The brain then puts the two pictures together to form one 3D image that has depth to it. Anaglyphic a stereoscopic motion or still picture in which the right component of a composite image usually red in color is superposed on the left component in a contrasting color to produce a three-dimensional effect when viewed through correspondingly colored filters in the form of spectacles. The mode of 3D presentation you are most familiar with are the paper glasses with red and blue lenses. The technology behind 3D, or stereoscopic, movies is actually pretty simple. They simply recreate the way humans see normally. Since your eyes are about two inches apart, they see the same picture from slightly different angles. Your brain then correlates these two images in order to gauge distance. This is called binocular vision. The binocular vision system relies on the fact that our two eyes are spaced about 2 inches (5 centimeters) apart. Therefore, each eye sees the world from a slightly different perspective, and the binocular vision system in your brain uses the difference to calculate distance. Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different. 3D glasses make the movie or television show you're watching look like a 3-D scene that's happening right in front of you. The screen actually displays two images, and the glasses cause one of the images to enter one eye and the other to enter the other eye. There are two common systems for doing this: Although the red/green or red/blue system is now mainly used for television 3-D effects, and was used in many older 3-D movies. In this system, two images are displayed on the screen, one in red and the other in blue (or green). The filters on the glasses allow only one image to enter each eye, and your brain does the rest. You cannot really have a color movie when you are using color to provide the separation, so the image quality is not nearly as good as with the polarized system.

3D in Theaters


The first 3D movie was in 1922. Real 3D movies work by projecting two copies of the movie onto the same screen, in a quick sequence. One series of frames is from the perspective of the left eye, while the other is from the perspective of the right eye. The left and right projections have different light polarizations. The left lens of the 3D glasses allows the light from the left projection to be seen by the left eye, but prevents light from the right projection being seen by the left eye. The right lens does the opposite. This has the effect of making the right and left eyes see slightly different versions of the movie. It allows you to view a real-world scene.
3dimax.jpg
The two images have slightly different 'perspectives' because they were recorded using a camera with two lenses, one for left, the other for right (just like your eyes). This system generates a combined stereoscopic image which is synchronized. This is how the 3D effect works.
In a passive 3D cinema, two images are projected onto the screen at the same time. Each image is projected with light that is only polarized in one direction. The screen has special reflective qualities that preserve this polarization. One lens filters out all the light that is undulating in one direction, and the other lens filter out all the light that is undulating in the other direction. So, just like with the old red and blue 3D glasses, each eye gets a different image, the brain combines the two separate images, and you get a 3D movie.
Active 3D is the basic idea that is still the same- to make sure that each eye 'sees' a different image. This set up requires two things: A display that can run at least 120 Hz, and a set of active 3D glasses. This system works because each 3D 'lens' in the glasses is in fact a one pixel screen. The display switches between the images intended for each eye back and forth very quickly. It shows the image for the left eye, then the right, then the left and so forth. There is no time where both images appear on the screen at the same time. The trick is that the screens in the glasses also switch back and forth at the same speed, so when the image on screen is for your right eye, the 3D glasses block your left eye. When the image on screen is for your left eye, the 3D glasses block out the right.
Is Active 3D or Passive 3D better? The active 3D system is more freely available to most home users but at the moment it only works for videogames. In short, you won't be buying 3D movies that use the same technology as the cinema for some time yet. However, the end for the passive system will win out. It's far less fiddly, and many consumers just want 3D technology that will work 'out of the box'. The active system simply can't do that.


3D Versus HD


3-D, 3 dimensional is a picture that enhances the illusion of depth perception. It came from stereoscopic photography, a special motion picture camera is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives), and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3-D films are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, primarily for marketing. How 3-D works is: the plate moves in 3 directions during the vibration. Up and down, side to side, and front to back. How exactly that 3-D movies are shot are with special cameras with two lenses spaced to simulate the eyes’ stereoscopic vision. Most of these movies are shown with viewers wearing clear polarized glasses. To have a 3-D movie you need three essential things: Projector, Z Screen, and Silver Screen. The projector alternates left and right video (three flashes of each frame) at six times the normal speed. The Z Screen sets up the polarization for each eye. Finally the Silver Screen is necessary to maintain the polarization.

In contrast to 3-D, HD (High-definition television), refers to video having
resolution higher than traditional television systems. HD has one or two million pixels per frame; roughly five times that of SD. Early HDTV broadcasting used analog techniques, but today HDTV is digitally broadcast using video compression. Essentially HD increases the pixels to make the picture look clearer, and 3-D makes the picture appear as if the images on the screen is coming towards you; the help of the 3-D glasses.

Connections and Cables


HDMI

In order to make a TV set 3D you must have a HD-3D ready television set, such as the Sony Bravia, supported by a HDMI version 1.4 cords. This cable up’s the supported resolution up to 4096x2160p24. This cord is a major milestone on the path for true 3D gaming. Some features of this futuristic cable are that this connector is 50% smaller than the size of the existing HDMI Connector. It also allows for support for additional color spaces which make colors more colorful and vibrant than ever. HDMI 1.4 is the standard for all home 3D devices.
HDMI has put out 4 versions of there cable since the start of the company. There first cable HDMI 1 supported a maximum band width of 3.95 Gbit/s. The second cord, HDMI 1.1, added support for DVD Audio. The third cord, HDMI 1.2, supported One Bit Audio and added additional color space. The fourth cable is HDMI 1.3 which increased the band width to 10.2 Gbit/s data stream. The fifth and final connection is the HDMI 1.4 which will make TV 3D.



HDMI Competitors



The new HDMI 1.4 cable supports 3D for televisions connected with computers and the internet. It offers 3D at 1080p resolution or higher, and requires two streams of images to be broadcast over the cable. Display port is HDMI’s biggest competitor. Unlike HDMI, Display port allows you to daisy chain, which allows you to transmit information from point A to point D, sending it to B and C along the way. DVI is another competitor, but the technology is outdated, and both HDMI and Display port are much better. Currently, HDMI is the gold standard for connections at the moment.

Brands of 3D


Samsung

Samsung was founded in 1969 in Suwon, South Korea. They first started out making refrigerators, TVs, calculators, and washers. Now they have created a new type of technology with their TVs. They have created a three dimensional image with your every day TV. Samsung partnered with DreamWorks Animation and Technicolor to create a great TV. Samsung created the worlds first 3D LED TV. This TV is compatible with Blu-ray 3D standards. The capabilities of 3D are brought to you in LCD, LED, and Plasma TVs, and Blu-ray players. The 3D brands include LCD 750, PDP 7000, LED 7000, and the Blu-ray 69000. These 3D TVs come with Samsung apps, like Blockbuster, YouTube, Monopoly, Facebook, Twitter, Pandora, Headlines from news, like U.S. Today and the Associated Press. These Apps are similar to the apps of Apple.

LG

LG was founded in 1947 in Busan, South Korea. LG produces electronics, chemicals, and telecommunication products. LG’s size ranges for 3D TVs are 42 inches to 72 inches. The company’s goal is to sell over 4000,000 3D TVs in 2010. Their first 3D TV created by LG is the LD360. This model will go on the market in April 2010. This LG TV is compatible with sky’s new 3D channels that will be launched in 2010. Families will be able to watch movies, entertainment, and sports in the great 3D dimension. LG has created great 3D TVs which are available in plasma, LCD, and LED TVs.LG.gif

Toshiba

toshiba.JPGToshiba was founded in 1875. In Las Vegas Nevada on January 6 2010 Toshiba announced they will be going to 3D from 2D. The TV will come in two sizes a 55 inch and a 65 inch. The 3D TV will go on sale at first in Korea. Later on in the year the company will take its product to the U.S.A. Toshiba’s TV will be able to convert video games, movies, and regular television to 3D. Toshiba’s TV will cost about $3,075. In addition to 3D TV Toshiba is making a 3D Camcorder. It will cost about as much as a TV at a price of $2,995.

Sony

Sony was established in May 1946. It was founded by Masaru Ibuka and Akio Morita . The companies original name was TTK, but when the company found out that another company was using that name sony-logo.jpgthey changed it to Sony. Sony comes from the English term Sonny boy. In Berlin Germany on September 2, 2009 Sony announced that they would be making a 3D TV to compete with Bravia’s. Sony also is putting out Blu Ray Disc products, Vaio , and Play Station 3 to enhance 3D viewing. Sony is using a method where the TV is alters the image for the left and right eye. It displays 1,920 to 1,080 pixels per eye! Sony's TV comes out at around $5,000 to $6,000 dollars. They also make glasses that cost $200 dollars a pair.

Phillips

Phillips was founded 1846 by Anton and Gerard Phillips. Phillips is coming out with a 56 inch HD 3D TV that has four times the resolution of any type of 3D TV philips-electronics.jpgcoming out. The TV has about 8.29 million mega pixels. Phillips is going to make a type of software 3D WoW Technology. WoW is an altering program that alters HD connection to turn to 3D. Phillips promises 46 views at once. Which means that is 23 times better than normal 3D resolution. This particular model of TV is only avaible to certain business. The TV will cost around $25,000. The regular Phillips TV has the ability to convert DVD’s into 3D also. An 42 inch Phillips HD 3D TV costs $8,999.



The Future of 3D




Future applications of 3D (Virtual Reality)


Uses of 3D in the future include 3D gaming, television shows, movies, and last virtual reality. Virtual reality will make you feel like you’re actually in the game and talking to the people. The structures and everything inside is going to be life like and you will feel like you’re actually present inside the game. Virtual reality in 3D will be like you are walking outside your house or really doing what the game is instead of playing on a gaming system. Virtual reality started with single-player worlds simulated on a local machine which was computer games, now the next step was to have multiplayer worlds, where several participants could interact with limited realism. Another important development were persistent worlds - Massively multiplayer online role**-**playing game (MMORPG**)** and "general-purpose" virtual worlds such as ActiveWorlds, Second Life, and There. It is difficult to predict the future of virtual reality with confidence. In the short run, the graphics displayed in the HMD will soon reach a point of near visual (but not behavioral) realism (see: "real time" raytracing, Real Time rendering). The audio capabilities will move into a new realm of three dimensional sound. This refers to the addition of sound channels both above and below the individual or a Holophony approach.equation.png
This shows that therefore any sound field can be reconstructed, if sound pressure and acoustic velocity are restored on all points of the surface of its volume. This will make virtual reality more real

What are the possible future TV shows in 3D


The future of 3 dimensional televisions is soon to become a common house hold item. The 3D television enhances the allusion of depth perception, which makes the object look like it is coming out of the TV. The many new technological fetes have made it possible to view your television in 3D. Your favorite TV shows can now be viewed in 3D, some with or without glasses. Brands such as LG, Sony, and Mitsubishi have already developed these televisions. With the LG and Mitsubishi TV’s you do not have to wear the 3D glasses. This is a big plus for those who worry about always wearing the glasses. These TV’s have the ability’s also to watch them in 2D, as well as in 3D. All shows can be watch in 3D with these developed features. With 3D TV’s becoming more and more popular, sports games and sitcoms are aware of what they need to provide the viewer. The camera angles and movements of the actors will provide the viewer the true 3D experience. Camera technology is also on the rise. Most TV shows and sporting events will now be shot with a 3D camera. This can assure the viewer the total use of this technology.

Future applications of 3D in movies

3D is the key to making movies of the future more interesting and life-like. Producers have been trying for years to make the viewer feel in the middle of all the action like they are there with the other characters. The challenge of this task has been expedited because of the development of 3D. Avatar a recent movie that had the highest grossing of all time used this 3D technology to make the movie extremely life like. Look for more movies like Avatar to be released. 3D’s biggest flaw is the glasses, everyone hates having to go into the theater and war the weird looking glasses. People with regular glasses have to manage balancing two pairs of glasses and takes away from the experience. New developments and technology are creating ways to not have to wear the glasses but still get the same real experience. Some dreamers think they can create a device that could make you feel in the middle of a movie and put yourself in it as your own character. This technology is far fetched but still possible. 3D is more than just having things pop out at you and make you scream in the theater it is about making you feel inside the movie but in reality you look behind you and the other people are sitting there intrigued like they are the only ones in the room. Animation movies in 3D are much tougher to make you feel involved in the movie because the animation does not seem real to you but by making a virtual and un-real world that you can enter through the 3D experience the movie can make the animation seem real. The biggest way that they are creating these 3D movies are by creating better and more innovative cameras that capture the footage and is easier to convert to 3D.
