One of the new trends in the optical business has been the emergence of 3D glasses, which provide three-dimensional images when watching films, videos and television, as well as when playing computer games. A number of the world's leading sunglasses and lens manufacturers have already released their first 3D products. What should you know about the features of these glasses that open a window to a new dimension for their users?

A budget option

If you want a budget option for homemade glasses, make paper ones. In this case, it is worth taking a frame made of cardboard, because it is easier to glue the lenses to it. You will also need large transparent tape and transparent silicone film, three felt-tip pens in red, blue and green, and sharp scissors.

Description of work:

• Let's draw and cut out the frame from cardboard. Let's attach the empty windows of the frame to the film and trace the outline with some marker or pencil, and then cut out two lenses;
• Next you need to do the painting. Let's paint one lens red, the other green and blue, on different sides. Let's wait until they dry;
• glue the lenses on both sides and secure them to the frame with tape. The red lens will be for the left eye, the blue-green lens is needed for the right eye. So we made an anaglyph product.

What you need to run a 3D movie on your computer

The minimum set for watching 3D films looks like this:

1. Utility player with support for a special filter.
2. The Anaglyph filter itself.
3. Anaglyph glasses.

The most popular program for playing stereoscopic movies is KMPlayer, but there are others - the last chapter will be devoted to them. The Anaglyph.ax extension is being implemented into the player - it is free and easy to install.

You can buy glasses for 100 rubles in a store/cinema, or, if you want a particularly economical option, you can make them yourself. To do this, you will need felt-tip pens, thin PET plastic (for example, from some box or frame) and a cardboard base. One “lens” needs to be painted blue, and the second – red, then cut out a “frame” from cardboard and attach both halves to it.

How to run a movie in 3D

Before you start watching a 3D movie on your computer, you need to do the following:

1. Download and install KMP player. During the installation process, you can select the Russian-language interface. Also remember which folder all the program files are moved to - this will come in handy in the future.

2. Download Anaglyph.ax: if it is in the archive, then unpack it, and if not, then do not run it, it will not open.

3. Move the filter to the root folder of your Player Items. If you have not changed the location, then by default it is located on drive C in the Program Files section.

4. Now you need to open the player and find the Configuration tab. A whole list of settings will open on the left; you need the Filter Manager section. Click on it and on the right click the Add an external filter button.

5. Go to the folder where you transferred the filter file and select it. For more precise settings, double-click on the filter name.

6. Specify that you will use Red and blue glasses so that the program will adapt the image to the features of your glasses.

7. The Depth of the scene value can be left at default or reduced a little - try to select it according to your own feelings.
8. Click Apply the settings and you are returned to the window with the selected filter. To make it work as expected, mark the Use Coercive option with a circle.

9. Now turn on the video and select 3D mode in the lower left corner.

Sometimes, upon startup, a warning window appears that says “Application Failure.” In this case, it is better to change the Use Coercive value to Set the degree and leave the numbers in the line unchanged.

3D playback programs

If for some reason you don't like KMPlayer, check out others that can play movies with a stereoscopic effect.

The best of this series:

CyberLink PowerDVD is capable of turning a regular monitor into a screen with a Blu-Ray effect. In addition to the illusion of a three-dimensional image, this player allows you to convert video to another format, mark and quickly find your favorite moments, resume watching from the moment you stopped, and much more.

Stereoscopic Player - the name speaks for itself. You can view 3D video and significantly improve the quality of the source material: correct the sound difference, adjust the color, etc. The player supports almost all types of extensions that currently exist, and at the same time has a simple interface.

Bino is a program designed specifically for stereoscopic films - for ordinary films the number of enhancing settings is much smaller. Using this player, you can show a movie on several screens (including using a projector). The range of supported extensions is also quite wide.

How they work

In adults, the eyes are located at a distance of 58 to 72 mm from each other. When a person looks at an object, a pulse called parallax is triggered in the brain. With it you see pictures from two points of view. We can explain in detail how 3D glasses work as follows: a person perceives the world around him from different angles, at a certain distance. Through the retinas of the left and right eyes, image information is transmitted to the brain directly to the visual center.

After processing the received images, a three-dimensional image is formed by comparing two signals. If you close one eye, you will not be able to perceive volumetric technology, since with monocular vision the signal will be supplied from one source. The brain center will immediately cease to perceive the distance, shape, size of objects and things. Because of this, people with visual impairments (for example, severe vision loss in one eye or blindness) have problems viewing 3D.

IMAX 3D – how to show 3D cinema Video

Of course, modern technology and computer developments make it possible to process an ordinary image into a three-dimensional one. That is, make a three-dimensional film out of an ordinary film. To watch this film you will also need 3D glasses. However, three-dimensional video, which was shot with a special camera, has higher realism and quality.

As you might expect, the glasses themselves for viewing 3D images may be completely useless without a special TV and 3D video. This is the case with polarization technology. However, one of the advantages of active technology is the fact that such 3D glasses and a TV make ordinary video three-dimensional. How is this possible?

Everything is very simple. The fact is that to achieve a three-dimensional effect, the picture does not need to be divided. Everyone makes active 3D glasses. Of course, to achieve the full 3D effect, you will need a video that has at least 50 frames per second.

For example, a regular video has 24 frames per second. That is, the eye sees 24 consecutive pictures per second, and the brain turns these pictures into videos. In order for active 3D glasses to work fully, creating the effect of a three-dimensional image, each eye must see 24 frames per second. The total is 48 frames per second, 24 for each eye separately. It is with this minimum frequency that active 3D glasses operate. Moreover, the greater the number of frames, the higher the quality of the 3D effect and the more pleasant the image will be to perceive.

History of appearance

At the beginning of the century, when the film industry was just beginning to develop, the first attempts to create a real image on the screen appeared. The first patent in this area was obtained by the Briton William Freese-Green. But only the Americans were able to popularize stereo cinema thanks to improved technology.

By the fifties, the number of cinema halls had increased all over the world and watching films had become a favorite pastime for children and adults. Unfortunately, this trend has had absolutely no effect on the public's interest in 3D video.

Modern 3D cinema is no longer the preserve of lonely enthusiasts. Large companies and corporations contribute to the development and improvement of digital technologies. Animated films are no longer inferior to live-action films in plot, quality and special effects. James Cameron's Avatar proved that innovative 3D effects can capture the imagination of millions of people.

How to choose

There are models costing over 20 thousand rubles, but you can find sales at a discount. Choosing stereo glasses for an interactive cinema is necessary both according to technical characteristics and personal preferences. For a computer, you should choose anaglyph glasses or shutter glasses. Don’t forget this fact: not only the purchased device is important, but also the components of the computer itself (for example, a monitor). Models with a battery that ensures uninterrupted operation are more expensive. If it is completely discharged, the glasses are recharged in 2 hours.

Video review of 3D glasses with anaglyph lenses Video

2.1. Children's 3D glasses with polarization

Polarized stereo glasses have a simpler design, so choosing them is easier.

As in the previous case, the first thing you need to do is check compatibility. To do this, simply indicate the TV model to the seller, and he will help you make the right choice.

Polarized 3D glasses also have a limited operating range, which does not exceed 6 meters. There are also models with a shorter range, so check this indicator with the seller.

Polarization type

The activity of children should be taken into account here. After all, they cannot sit still and constantly turn their heads.

For small viewers, circular polarization is the best choice, since in this case the image quality does not deteriorate when the head is tilted. In this case, wearing glasses with linear polarization, you must watch the film strictly perpendicular to the plane of the screen. When tilted, image quality drops significantly and 3D effects disappear.

How to make anaglyph 3D glasses yourself

The easiest way to make 3D anaglyph glasses is to use blue and red film and cardboard to make them.
By the way, such 3D glasses can often be found on sale. The method is quite simple: make a frame from cardboard (you can also use thick paper) and glue colored film there. If there is no film of the appropriate colors, then you can use paint from a marker or ink for an inkjet printer. Coloring directly with a marker is not recommended, because the image quality of 3D glasses made in this way may be unsatisfactory.

To make anaglyph 3D glasses from plastic or glass we will need:

• transparent film for printer,
• the same paint as in the first case,
• glass lenses, or plastic CD packaging,
• old frame.

And here's what the manufacturing process itself looks like.

1. We make light filters. To do this, apply red paint to one glass, and blue paint to the second. We apply a pre-prepared transparent film over the paint.
2. We take out ordinary glasses from the old frame and insert multi-colored filters into them.

3D glasses made of plastic are easier to make; more precisely, the process of making color filters is simplified. The paint is applied directly to the lenses, which are pre-cut from plastic. To make the cutting process easier, the plastic is preheated in hot water. And after the work is completed, the edges of the lenses are processed using sandpaper.

By the way, about paint. The printer uses only three colors - blue-green, magenta and yellow. To get red, you will need to mix yellow and blue-green in equal parts.

Active technology

Active 3D glasses for TV, also known as shutter glasses, have their own distinctive features. The most important thing is operation from a battery or a small battery. In the first case, the glasses can be charged, in the second, the battery can be constantly changed. The battery lasts up to 70 hours of operation, and charging time will be 2 – 3 hours. The battery will last for 120 hours. These models have an on\off button and a charge indicator, with which you will know in advance when to charge them or change the battery. They connect to the TV via an infrared sensor, which allows you to look at the screen from a distance of up to 12 meters. The advantages include the high quality of 3D images, which is several times better than passive ones

Before choosing 3D glasses for your TV, pay attention to the instructions for them. There is a “Compatibility” column, which will tell you about suitable TV device models

The disadvantages include the expensive cost of such technology, more than 2 times, and eye strain. Due to the fact that the lenses are constantly working, closing and opening access to the image, it is not recommended to use them for more than 4 hours. Also, many users note a decrease in quality when moving the head. Those. You need to watch 3D content motionless. If you are a fan of viewing three-dimensional images in excellent quality, then you will like this type of glasses.

Where to buy and how much they cost

You can purchase 3D glasses from various trade organizations, which include hardware stores or online stores. Many cinemas independently sell various types of glasses, and sometimes rent them out or offer them for free while watching the film.

The cost of the product depends on its type and design . The most inexpensive models cost about 800 rubles, and you can also find glasses powered by batteries or an accumulator, and their cost varies from 3 to 12 thousand rubles. There are even designer models that are distinguished by their unusual appearance and high cost.

How to use 3D glasses

In order to understand how to use 3D glasses correctly, you need to understand how they work and how the 3D imaging technology itself works. This will allow you to understand the principle of operation of the TV and glasses, which in turn will help the viewer understand how to use the glasses correctly.

So, the essence of the technology is to provide two slightly different images - a different image for each eye. Thus, the brain receives two pictures, two versions of the same object. The brain combines these pictures and creates one three-dimensional image. It is thanks to the fact that a person has two eyes that we can estimate the approximate dimensions of real objects, their height, width and depth.

Today there are three image separation technologies:

• Anaglyph;
• Polarization;
• Active.

Only certain glasses are suitable for each of these technologies. For example, for active technology there are shutter glasses. If the video clip has an anaglyph image division, then to achieve a 3D effect you should use anaglyph glasses (blue and red lens). Accordingly, when polarizing image separation, passive (polarizing) glasses are used.

1.1. Shutter 3D glasses

Active (or, as they are also called, shutter) 3D glasses have this name because each lens has a shutter that can close and open more than 150 times per second. The essence of their work is that while watching a movie, the shutters open and close alternately, providing each eye with a separate image.

Everything happens so quickly that the viewer does not have time to understand anything, but the brain receives two pictures and turns them into one three-dimensional image. These glasses can only be used with a certain TV that has an infrared transmitter that sends signals to the glasses. Everything happens the same as with the remote control.

Setting up 3D glasses with shutters is quite simple. To do this, you just need to turn them on and synchronize with the TV. In this case, on the TV itself you need to select an image division method that corresponds to the division method in the film itself. Only after this you will be able to enjoy a full 3D image.

1.2. Polarized 3D glasses

Polarized glasses do not require any adjustment before viewing. You only need to set up the TV itself. In the settings you need to select the image division method. There are 4 methods of separation using passive technology:

• Vertical stereo pair;
• Horizontal stereo pair;
• Time-lapse stereo pair;
• Interlaced stereo pair.

It doesn't matter which method is used, as long as the TV settings match the video being played. The essence of the technology is that the video itself is divided into two streams

Each of their streams has a different polarization - vertical and horizontal. The lenses in glasses also have different polarizations. In other words, for example, the right lens completely blocks the flow of video with vertical polarization and transmits video with horizontal polarization. The left lens, on the contrary, transmits video with vertical polarization, blocking video with horizontal polarization.

Thus, each eye sees a separate image. Next, the brain turns two different pictures into a 3D image.

1.3. Anaglyph 3D glasses

Anaglyph 3D glasses work the same way as polarized glasses. The only difference is that the video stream is not divided by polarization. If you look at an anaglyph video without glasses, you will see a cloudy image with blue and red shadows.

The glasses have a blue and a red lens. Thanks to this, shadows are completely removed by glasses, and 2D video turns into 3D.

Anaglyph glasses, like polarized ones, do not require any synchronization or adjustments. All image settings are made on the TV itself, so that it can separate the image using the required technology, be it polarized, anaglyph or active glasses.

Possible reactions to a 3D image

The worst sufferers of 3D video are children, hyperexcitable people and people who are depressed. Drinking men and women react poorly to it. While watching stereo films, these people's brains work even more actively, which is why they soon feel unwell.

The most common symptoms:

• headache;
• nausea;
• mild disorientation;
• dizziness;
• temporary visual impairment;
• feeling tired;
• slight muscle twitching;
• muscle weakness.

Advice!

If alarming symptoms appear, pause or stop watching the movie. If unpleasant sensations appear regularly and cause you a lot of discomfort, feel free to consult a doctor.

Note that for some people watching 3D video is undesirable and even dangerous. Moreover, the passion for stereo films can have extremely serious consequences for them. For example, a person with epilepsy may have a seizure during a video session.

Contraindications to wearing 3D glasses:

• epilepsy;
• severe vegetative-vascular dystonia;
• serious mental disorders;
• lack of full binocular vision;
• some types of strabismus.

Ophthalmologists do not allow people with poor vision to wear 3D glasses over diopter glasses. Doctors advise such patients to purchase contact lenses and wear them to the cinema.

Curious!

According to American scientists, 5-12% of the population suffers from stereoblindness. People with this condition are unable to perceive 3D video. The main causes of stereoblindness are strabismus and anisometropia (different visual acuity of the two eyes).

What types of 3D glasses are there?

It should be said right away that 3D technology can be passive and active. The active view includes line splitting technology. This is the most progressive method. Passive technologies include anaglyph, polarization, and parallax technology. The latter differs in that the image is presented alternately to each eye. One of them perceives the image, and the second is closed by a parallax barrier. This technology does not require special devices

Another important thing here is precise placement in front of the monitor. Otherwise we will not get a full three-dimensional image

As you understand, different 3D glasses are also needed for different image transmission technologies:

• anaglyph,
• polarizing,
• bolt action

Anaglyph technology is considered by many to be an outdated option for transmitting 3D images. It is based on the color division of the picture. Therefore, anaglyph glasses consist of a red and blue lens, which act as a light filter. Many people believe that the image obtained using this technology is not three-dimensional enough. But there are those who are quite happy with this. Moreover, if we talk about price, this is the cheapest option.

Polarizing technology and 3D glasses for viewing such images have become very popular recently. They are used both in cinemas and for watching content at home, for example, on a computer or on TV. This technology is based on the refraction of the light falling on them.

Each of their lenses only accepts the image that is intended for it, and it simply blocks the image for the second lens. In addition to regular polarized ones, you can also buy 3D glasses with diopters. But still, this technology also has a drawback - it is a limited distance, about 5 meters, between the TV and the viewer.

Gate models are used with active line separation technology. They differ in that the image is divided not on the TV screen or computer monitor, but on the viewing device itself. And image synchronization is achieved using an infrared port. The essence of their work is that the lenses are closed alternately 150 times per second using special shutters.

This technology can be called the most advanced of all available, but it requires a powerful video card, additional connectors for charging and connecting an IR signal transmitter.

What it is

These glasses use special filters instead of standard lenses, and each eye has its own light. Color coding ensures stereoscopic images.

Human vision is structured in a specific way, so even if you combine two pictures, you will get the feeling of viewing a single image.

Cinemas provide anaglyph glasses, which are equipped with glasses of different colors. A red filter is provided for the left eye, and a blue tint glass for the right eye. These glasses make it possible to view a three-dimensional image, so it feels like the action goes beyond the boundaries of the white screen.

It is the involvement in the events taking place in the film that is considered the most significant advantage of three-dimensional films. The quality of this effect is influenced not only by the technology used to create the film, but also by the tool used for viewing.

Types of 3D glasses

Nowadays, you can find four types of stereo glasses on the Russian market:

• Anaglyph;
• Polarizing;
• Bolt;
• Video Glasses.

The cost of 3D glasses directly depends on the technology. The rule applies: the more expensive, the better. The most expensive models allow you to enjoy extremely high quality 3D effects. However, it is worth remembering that not everything depends on glasses. The TV itself, that is, its quality and supported 3D technology, also influences a lot.

In addition, the quality of the video itself that you want to watch is very important. However, further we will talk directly about glasses

So, let's take a closer look at each type.

1.1. Anaglyph technology

This is the simplest three-dimensional imaging technology, which was known back in Soviet times. Surely everyone remembers paper glasses with red and blue lenses. They can even be made from improvised materials, using thick paper, colored markers and transparent thin plastic, for example, from a PET bottle.

The cost of 3D glasses with anaglyph lenses is affordable for absolutely everyone. Their cost can range from 30-50 rubles (paper frames) to 300-400 rubles (plastic frames). Of course, more expensive options have a durable frame and stylish design, but the quality of the effects does not depend on this at all.

You can make anaglyph stereo glasses yourself from PET bottles and cardboard. To do this, you need to cut out the shape of the frame from thick paper (whatman paper or packaging cardboard), and also make holes in it for the lenses. The lenses are cut from a plastic bottle (it is worth remembering that the plastic must be transparent, without any tints). Next, the cut out lenses need to be colored with regular markers. The left lens is red, the right lens is blue (light blue or cyan).

Checking the product is quite simple. There are a lot of anaglyph pictures and verification images on the Internet. All you have to do is look at one of these photographs with the glasses you made.

1.2. Polarization technology

Polarization technology is newer and more complex than anaglyph technology. Such glasses can no longer be verified on a regular image. Moreover, to display 3D movies using this technology you will need a special TV.

As a rule, when purchasing a TV, 4 pairs of polarized glasses are already included in the package. However, sometimes this is not enough. Very often guests come to us - friends and family. In such cases, you cannot do without two or three additional pairs.

How much do polarized 3D glasses cost and where can you buy them? It's simple. They are available in the assortment of any household store. In addition, they can be ordered online. However, it is worth remembering that in the latter case, you will not be able to check their compatibility with the TV, as well as try them on and understand how comfortable they are to use.

The price of polarized 3D glasses can range from 300 to 1000-2000 rubles. The difference between them can be in the material of the frame, the quality of polarization, as well as in the operating range. The maximum range does not exceed 6 meters.

Of course, you can find more expensive models, but they will not differ from the usual ones in absolutely anything except design. It is worth remembering that there are two types of polarization:

• Linear;
• Circular.

Linearly polarized lenses have a lower cost. However, their disadvantage is that when the head is tilted, the 3D effect and image quality are greatly reduced. Circularly polarized lenses do not have this drawback, but they are also more expensive.

1.3. Bolt technology

This technology is the most complex and expensive. One factor in the high cost is the glasses themselves. They have lenses with liquid crystal shutters. In addition, an infrared sensor is built into the frame, which is necessary for synchronization with the TV, which allows them to work correctly (close and open the shutters exactly at the right moments).

Despite the cost, this technology is most widespread among users. This is due to the highest quality 3D effects. The price of 3D glasses with shutters can range from $150. Moreover, when purchasing, you need to remember that specific shutter glasses can only work with certain TV models.

The indicated cost can range from 120 to more than 300 dollars. Here, there may also be differences in the operating range (no more than 6 meters), the quality of lenses and LCD shutters, size, type of power source (battery or batteries), the presence of power indicators, as well as other factors. There are universal shutter 3D glasses that can work with different TVs, but their cost is slightly higher.

The best virtual reality glasses for consoles

Active or passive 3D glasses, which is better?

Before choosing glasses for watching movies and playing games in 3D, you need to find out which ones are better

It is also important to consider the nuances of compatibility: in some cases, glasses must match the capabilities and functions of the TV or monitor. It determines whether polarized glasses or active ones will work.

Passive glasses

The situation is simplest with anaglyph 3D glasses. They do not put forward any special requirements for equipment. In them you can watch a 3D image either on a TV, on a monitor, or printed on a sheet of paper. To do this, you only need a film recorded in anaglyph format or a special player. KMPlayer can convert regular video to anaglyph on a PC.

However, it should be taken into account that it is best if the content is initially designed for 3D, that is, filmed on a stereo camera. An ordinary flat picture after conversion to three-dimensional will not give such a pronounced effect of presence. It’s easier in the case of games: you can provide 3D rendering using Nvidia 3D Vision video card drivers or third-party software with similar functionality. The video card will render the image with its own color filter for each eye.

Pros of anaglyph

• Price. Anaglyph 3D glasses are the cheapest, their cost starts from 20-30 UAH.
• Weight. Glasses weigh the same as regular sunglasses or prescription glasses, or even less. Cardboard models (the kind they give out at anaglyph cinemas) are even lighter.
• Compatibility. The glasses are compatible with any image sources, digital and analog.

Cons of anaglyph

• The effect of presence when viewing with anaglyph glasses is not always sufficiently pronounced.
• Color rendition in such glasses can sometimes be distorted and not correspond to reality.

With polarized glasses everything is more complicated. The fact is that they require a monitor that has a special coating that sets the polarization. Typically, the even and odd rows of the matrix are covered with different layers, the difference in the polarization of the optical wave between them is 90 degrees. Budget TV models rarely have such coverage. For example, a 3D TV LG 55UG870V costs more than 30 thousand hryvnia. But this does not mean that without several tens of thousands there is nothing to look for. Polarized 3D is supported by many monitors and TVs from LG, Sony, and Philips.

Pros of polarization

• The weight of polarized glasses is the same as their anaglyph counterparts.
• Autonomy. Like anaglyph glasses, polarized glasses do not require a power source.
• The cost of polarized glasses is higher than that of anaglyph glasses, but is within affordable limits.
• The effect of presence is often better expressed than with anaglyphs.

Disadvantages of Polarization

• The viewing angle of polarized glasses is often limited.
• Compatibility. To view 3D, a polarization-capable monitor or TV is required.

Active glasses

Active shutter glasses for TVs are often included with the device. This is due to the fact that synchronization between the controller and TV is required for correct operation. Synchronization methods may differ between different models, so it will not be possible to create a universal accessory. Everything is simpler in the PC world: devices, like Nvidia 3D Vision branded glasses, are connected via USB and come with software for converting images into 3D. The only limitation is the monitor's refresh rate. It must be at least 120 Hz.

Pros of shutter glasses

• High image quality. Thanks to the high frame rate, the image on the screen is better perceived by the eyes.
• Providing a tangible presence effect. The image on the display is not divided into a stereo pair and does not alternate line by line, due to this increased clarity is achieved.

Disadvantages of shutter glasses

• Limited compatibility. Shutter 3D glasses only work with a narrow range of TVs.
• High price. The cost of shutter glasses can reach several thousand hryvnia.
• Increased weight. The electronics and battery inside the glasses make the design heavier.
• Lack of complete autonomy. The glasses need to be charged or the battery changed, and their normal operation is guaranteed over a limited distance.

Modern technologies and methods for realizing 3D films

Now on the market there are various possibilities for implementing stereoscopic cinema on cinema screens, monitors and televisions.

• Anaglyph
• Polarizing
• Interference
• Without glasses

Each of the 3D implementation methods has advantages and disadvantages. but each of them is based on the principle that each eye sees its own picture, and the brain combines 2 images, resulting in a three-dimensional volume.

3.1. 3D glasses for monitor

To watch 3D movies on your computer, you can use regular anaglyph 3D glasses. However, this is the simplest and lowest quality option. For lovers of higher quality, there are special 3D glasses. However, it is worth noting that the monitor itself must also have a frequency of at least 120 Hz.

The most popular monitor glasses are Nvidia 3D Vision. Of course, they are more advanced and allow high-quality 3D effects to be achieved, but they are also expensive.

Before purchasing, you should consider all the pros and cons of certain glasses. For example, the disadvantage of active 3D glasses is a slight darkening of the image. However, modern TVs compensate for this effect by slightly increasing screen brightness. And this happens automatically. The positive side of this technology is that the screen itself is not divided, which allows you to watch movies in HD.

The advantage of polarized glasses is their low cost. At the same time, you get fairly high quality 3D effects. However, due to the division of the TV screen into stereo pairs, the image resolution is halved.

Now you know what 3D glasses are, and you can choose the most suitable ones for a given situation. It is worth remembering that, despite all the differences, all types of 3D glasses work on the same principle. The choice of technology is yours.

Device setup features

There are many ways to reproduce a movie in 3D format. The most popular of them: buy a TV with a 3D function, use a computer to which a 3D monitor is connected and has a powerful video card, or the easiest way is to go to the cinema. The first two options are not feasible for most users, since purchasing such equipment costs a lot.

If you are a fan of watching movies under a blanket in your apartment, then to activate the 3D function you only need a computer with a monitor or a laptop.
