3D Display Technology - What Is It and How It Works?

The 3D display technology is revolutionizing the television and cinema viewing experience. The latest marketing gimmick to promote movies and video games is to make a 3D version of them. Once consumers have got a taste for the new technology, it is likely to change viewer ship in a big way. But the technology is not currently cheap - a reason why marketers instead of regular consumers have taken to it in a big way. 3D LCD display rentals have also seen a boost owing to the tremendous response the technology has received at the trade shows and other marketing events.

How Does 3D Work?

Strange though it may sound, 3D actually works using the natural depth perception that human vision possesses. To put it simply, we have two eyes at a distance from each other, approximately three inches. Each eye sees an image or scene from a different perspective or angle. Our brain merges the two perspectives and processes them further to calculate distance or depth of the object being viewed. When visuals send a different image to each eye, a 3D effect is created. 3D movies or games can be viewed only by wearing a pair of special color filter glasses, polarized glasses or shutter glasses. All 3D TV manufacturers sell these special glasses with the TV units. For those opting for 3D LCD display rentals, the equipment rental firm will provide the glasses along with the display unit.

The latest in technology however is 3D viewing without glasses. Contrary to the first impression, the technology still requires a special lens. For viewers who dislike wearing goggles while watching TV, a few manufacturers have come up with lenticular lenses, which could be used instead. These are fixed on the screen but needs to be exactly aligned to the image being viewed. Using lenticular lenses may seem more comfortable than wearing glasses, but they come with a set of conditions like specific viewing distance and so on. 3D LCDs like the ones developed by Sharp come with a parallax barrier that controls the direction of light and the way it is viewed.

How much does a 3D LCD TV cost?

The worst thing about this great technology is that it costs a bundle. However, the average consumer seems quite ready to pay the price for such extraordinary viewing experience. 3D LCDs can cost around $3000 on an average with base models coming in at $1700. And the ones with better features can cost anywhere between $6000 and $7000. Each set comes with only a pair of goggles so additional glasses will need to be purchased for ideal family viewing.

Where price is a deterrent, consumers can always look to an equipment rental service. 3D LCD display rentals solutions are already being offered by many equipment rental firms. Companies like Panasonic, Samsung, Sharp, Sony, Toshiba and LG are pushing their 3D LCD models with many interesting deals offers. The internet is often the best place to begin looking for these special deals.

Difference Between 2D and 3D Animation

Animation is a field of art or science that has the capability to impart life and zeal to non living characters. Basically it is based on the phenomenon of persistence of vision that allows the visual illusion of the objects. It is a phenomenon of an eye in which an image continues to appear in one's vision after the exposure to the original image has ceased. This happens for about one twenty-fifth of a second. In early days animation was restricted to only hand drawings. But with the advent of technological know how animation has got a new face that is known as two dimensional and three dimensional animations. A three dimensional animation is far better than two dimensional. It adds more vigor and vivacity to animation.

Animation is simulation of movement created by a series of pictures or frames. It starts with drawing independent pictures and putting them together in a frame to form the illusion of continuous motion. Two dimension means that the picture is drawn with help of two coordinates of geometry. These are designated as x (horizontal) coordinate and y (vertical) coordinate. 2D is flat which means that if a picture is turned to the side then it becomes a line. Whereas 3D includes an extra dimension known as z coordinate which stands for rotation and depth. The basic difference between 2d and 3d can be illustrated by drawing a rectangle and a cube. Rectangle is a 2D figure whereas cube is a 3D figure. 3D presents the object from every possible direction like in real life. 2D bitmap or vector graphics are used to create 2D animation figures.

Various techniques that are used in creating 2D figures are morphing, twining, onion skinning and interpolated rotoscoping. Whereas 3D animation involves digital modeling of characters. Various steps that are involved in 3D animation are character sketching, character modeling, scene building, texturing, lightening and camera setup, rendering, lightening and camera setup, rendering, editing and mixing etc. Other techniques that can be applied are the use of mathematical functions, simulated fur or hair and the use of motion capture. In this way we can extract greater use of multimedia through 2D and 3D animation.

The History Of 3D Films And Glasses

Three dimensional films are motion pictures that utilize special technologies to enhance the viewer's illusion of depth perception. Special cameras and equipment are used to film the images and then stereoscopic hardware and eye wear are used to provide viewers with the feeling of depth. The most crucial part of the 3D movie viewing experience are the glasses that must be donned in order to do so.

The era of stereoscopic movies began in the 1890s. Around that time, a man named William Friese-Greene developed a three dimensional movie making process and filed a patent for it. His technique consisted of playing two side by side on a screen and using a stereoscope to view the images as one. Though his work was groundbreaking, Friese-Greene's method was too unpractical for theatrical use.

The very first 3D film that was played to a paying audience was The Power Of Love. It premiered in 1922 to a packed Los Angeles Ambassador's Hotel. The movie consisted of dual red and green strips and, to view it, the audience members were given anaglyph glasses. Despite receiving rave reviews, the film was lost after a brief exhibition in New York.

Small jumps in three dimensional technology were accomplished slowly over the next few years but by the early 1930s, interest in the format had dipped. The Great Depression had swept through the country and left behind a nation filled with people who were understandably uninterested in the film industry in its wake.

It wasn't until 1936 that MGM commissioned and released a series of 3D movies called Audioscopiks. The movies were collectively considered a massive success and nominated for an Academy Award for the short subject novelty category.

Starting in 1952, Hollywood experienced a sort of golden era when it come to 3D films. Every single major production company released a number of three dimensional movies during this period. In fact, so many films were released that the general public began to tire of the format. By the mid fifties, the decline in interest and high costs of shooting 3D movies had caused most production companies to abandon the format altogether.

In the early seventies, a new method called Space-Vision 3D had emerged and helped to usher in a revival for the genre. The latest technologies allowed for three dimensional films to be shot and played in a way that didn't hurt the audience member's eyes when watched. When Stereovision used the new technology to make the immensely popular and profitable soft-core film, The Stewardess, other companies began to once again follow suit.

Beginning in the early 2000s, the technology used to create these films has been progressively improving. The 3D glasses used to watch the films are no longer the flimsy cardboard pieces that they once were. Most movies today require polarized glasses to view them. The objects closely resemble regular sunglasses both in their frame and lenses. The devices offer a more realistic viewing experience and are the gold standard for most 3D movies and theme park attractions.

Samsung 3D TV LED Leads the 3D TV Revolution

If you're eager to get the 3D experience in your own living room, what items will you need in order to be ready for 3D TV? First of all, you'll need a TV that is specifically designed for 3D, and the great news is that currently there are some excellent offers available. One example of these exceptional deals is the Mitsubishi WD-60638 60 inch 3D-ready DLP HDTV that is available online for, if you can believe it, less than $1000.

This is an awesome TV at a ridiculously low price but you might chose instead the Samsung 3D LED TV UN40C7000, which has a manufacturers retail price of $1,999, but you can find it for less with some great discounts. Another Samsung best seller on 3D TV's is the UN46C7000 which is currently available with a savings of over $500. One of the great benefits of buying online is that there are some websites that offer free shipping on these TVs, which means no hauling it from the store yourself, if you even have the truck it takes to fit it into.

You will most likely need a 3D starter kit to go along with most any of the 3D TVs you might buy. Usually you'll be required to purchase a starter kit that is the same brand as the TV although it looks like the Samsung kit will also work with some of the Mitsubishi TVs. You should make sure before you purchase either the TV or the starter kit. Manufacturers have hinted that the technology will most likely advance to the point where you won't have to wear 3D eyeglasses. But if and when this might happen is anybody's guess and how long do you want to wait for eyeglass-free viewing? Besides, the price for the new technology will undoubtedly be much higher than the price of the current 3D televisions.

So what exactly do you get in a 3D starter kit? There's no set definition of what comes in one, so it'll depend on which manufacturer you choose. If you decide on a C7000, C8000 or C9000 series Samsung TV, you'll want to pick up the 3D starter kit from Samsung. Their package includes 2 pairs of adult 3D active glasses which are battery-operated, in addition to a specially-released 3D Blu-ray movie named Monster & Aliens. The retail price on the eyeglasses is about $150 a pair, so make sure you really need them before you buy any additional ones. If you're going to be inviting members of your family or friends over a lot to watch 3D movies, a pair of glasses might make a good Christmas gift for them.

You might think you're good to go at this point, but you actually need one more component to get the 3D experience. You also need a piece of equipment that will play the 3D movies. Examples of this equipment are a 3D Blu-ray player, a cable box (make sure you have a subscription that gives you access to the right channels), or a Playstation 3 box, as long as you've updated it with the absolute latest 3D capability.

Different from the 3D starter kit, there's more choices available to you if you decide on a Blu-ray player since you don't have to buy the same brand of player as what the TV is. The LGBD570 model Network Blu-ray Disc player continues to be a best seller and has earned a lot ratings that are four and five stars. Part of the reason for its high ratings is its excellent video and audio clarity. Another benefit of this particular player is that it is wireless, allowing you to connect to your wireless broadband router and access all kinds of multimedia like HD movies from Netflix (assuming you have a Netflix subscription).

One final component you may need to put the finishing touches on your 3D TV setup is an HDMI cable. This cable is used to connect your television set and your disc player and may not come with either one of these pieces of equipment. Be sure to find one that maintains high quality transmission even at high speeds. Luckily, if it does turn out that you need to purchase this cable, they are relatively inexpensive especially when you compare them to all the rest of the components you'll need to put together to be ready for 3DTV.

3D: The Future of Gaming

Television, movies, and video games have been restricted to the 2D world for a long time, but it seems they have served their time and are being released into the 3D world. 3D movies have been constantly improving in quality for the past few years and have done so well that TV is following in those footsteps. Plasma, LCD, and even LED TVs were just not enough, now the consumer has a hunger for the next evolution of the screen; 3D.

In the past, the largest barrier to the 3D market was the content. It wasn't so much that the devices were not ready, but that there wasn't much content available to be seen on the devices. That's all changed. Samsung televisions are available now that are ready to show you all the 3D content that is out there and available for your consumption.

If movies and TV are moving into the 3D world, then it's expected that video games cannot be far behind. In fact, Sony PlayStation 3 has already entered the 3D gaming market, which is sure to expand exponentially over the next few years. Currently the PS3 is the only system on the market that is capable of displaying games in 3D and that is a huge advantage in new market.

All Hype?
The burning question that remains, is whether or not the 3D gaming evolution is all just hype that isn't ready for prime time. This isn't the first time that video has tried to break the 3D barrier and all the previous attempts claimed to be ready for mainstream as well. The difference this time is that the technology has moved forward and there is far more 3D content available than ever before and the consumer is much more aware of all that content. So the current ecosystem of game developers, TV technology, broadcasters, and publishers all seem to be aligned to bring 3D entertainment "to life".

The availability of 3D TVs has been the missing piece of the puzzle for the gaming industry. Video games have a much lower entry barrier to 3D than films or broadcast TV, because there is no infrastructure for the game publishers to replace. Video games don't require new cameras or editing equipment since their focus has been on displaying 3D worlds in a 2D environment for at least the past decade. The problem has been how to get the 3D content to the consumer.

The short answer to the question is that it doesn't look like hype this time.
