Today, an increasing number of films and cartoons are produced in 3D format, so that viewers can enjoy three-dimensional images and three-dimensional images; they are given special red-blue anaglyph 3D glasses. The illusion of a three-dimensional image is created through color coding, i.e., instead of ordinary lenses, such glasses have special light filters; a red color filter is used for the left eye, and a blue color filter is used for the right eye. In order to make such glasses yourself, you do not need any special skills or expensive materials. This article will present two master classes with which you will make 3D glasses at home using cardboard frames and old glasses.

In these videos, masters share the secrets of creating 3D glasses. It will be shown how to make such glasses for viewing three-dimensional images at home and using scrap materials.

How to make 3D glasses from cardboard frames

The first option for making such glasses involves using a cardboard frame. In order to make 3D glasses with your own hands, you will need to purchase the following materials: a sheet of cardboard, a pencil, scissors, thick transparent silicone or transparent film, wide transparent tape and markers of three colors, namely blue, green, red.

First of all, on a sheet of cardboard, using a simple pencil, you need to draw the contours of the frames and spectacles. Then you need to bend a sheet of cardboard in half and use scissors to cut out the shape of glasses without lenses in duplicate. Then you should cut out two equal-sized squares from transparent film. Next, one square must be colored on one side with a blue marker, on the other side with a green marker. The second prepared square must be colored on both sides with a red marker. Then both painted squares must be covered with tape on both sides, but in such a way that there are not even small air bubbles left, otherwise the image quality will be poor. At the final stage, the prepared squares must be glued to the cardboard form of the glasses, and a second cardboard form must be glued on top.

How to make 3D glasses from old glasses

You can also make 3D glasses at home according to the second option, namely: using old glasses. To work, you will need unnecessary glasses, transparent thick film, red and blue markers, and scissors.

First you need to prepare your glasses, take out your regular lenses. According to the shape of the old lenses, it is necessary to cut out two parts of the same shape from a thick transparent film. Then one part should be colored with a red marker, the other part should be colored with a blue marker. It is important to paint the parts evenly with a marker and make sure that no streaks or smudges form. After the parts are painted, you need to wait a little while the paint dries. Next, you need to carefully insert the prepared colored parts instead of the lenses, the red part should be inserted instead of the left lens, and the blue part - instead of the right lens. After this, the 3D glasses can be considered ready, and you can start watching movies or cartoons in 3D format. But do not forget that viewing images in such glasses puts a lot of strain on the eyes; adaptation to such glasses will take about thirty seconds, and after removing the glasses, it usually takes some time for light perception to be restored.

3D video is becoming more and more popular, new films and cartoons are increasingly being released in 3D architech.com.ua. Unfortunately, cinema tickets for a 3D film are still very expensive, and in some cities there are simply no such cinemas. If you want to see what 3D is like, you can try making .

We would like to point out right away that home 3D glasses will not help you enjoy three-dimensional images in IMAX format - the technology is not the same. Red and blue anaglyph (anaglyph) glasses allow you to “trick” the brain and create the illusion of a three-dimensional image through color coding.

3D glasses are inserted instead of lenses special filters, usually red for the left eye and blue or blue for the right. If you look through such glasses at an anaglyph image (picture or film), it will appear three-dimensional. The disadvantage of anaglyph is incomplete color rendition and possible discomfort during viewing and after removing glasses.

Making 3D glasses at home is quite simple: for this you will need to use any available method paint two lenses in CMY colors(cyan, magenta, yellow - blue-green, purple, yellow). Blue-green is for the right lens, red (a mixture of yellow and purple) is for the left. We will tell you several ways to quickly and easily make 3D glasses at home.

To make 3D glasses with your own hands, you will need frames for glasses, material for lenses (filters) and tools for coloring lenses. You can use frames from cheap old plastic glasses or just make one out of thick cardboard.

Best suited for making light filters thick transparent film. We advise you to take film for printing on an inkjet printer - it has a gelatin layer that can absorb ink. But, in principle, any thick film will do. Using sharp small scissors, cut out two neat ovals from the film - the future lenses of your 3D glasses (for a film with a gelatin layer you will need four of them). If you are using old plastic glasses as a basis, cut out the filters according to the shape of the lenses of these glasses.

Then you need color the filters in red and blue. Easiest to use for this alcohol marker for rims- it does not wash off or wash off. One film is evenly painted over with a red marker, the second with a blue marker. To achieve uniformity, you can remove the alcohol stick from the marker and squeeze it onto the film. Wait until the surface is dry before inserting lenses into glasses. The alcohol should completely evaporate.

Printer film with a gelatin layer can be dyed using old color cartridge. To do this, you will need an old inkjet printer cartridge, three ink bottles, three disposable syringes and glass plates.

First, you need to open the cartridge and remove the ink-soaked foam sponges from it. To “squeeze” ink out of sponges, place them in syringes and press the plunger, squeezing the ink into the bubbles. You will need three colors of ink: blue-green (cyan), yellow (yellow) and magenta (magenta).

To get red, you need to mix yellow and magenta ink in equal proportions. Pour the resulting red ink onto a glass plate and place the cut out lens on it, gelatin side down, so that the ink is absorbed into the gelatin in an even layer. Then take the second piece of film, do the same procedure with it and attach the pieces with a gelatin layer to each other so that they stick together. A blue-green filter is made in the same way. After a few days, the lenses will dry and can be inserted into the frame.

Ready-made filters can be inserted into a ready-made plastic frame or glued into a homemade cardboard one. The red filter is for the left eye, the blue one for the right. How to check if you can make 3D glasses at home? Just put them on and look at the stereo image. Ready-made anaglyph pictures can be downloaded on the Internet or made yourself using special programs.

Many people have probably thought about how to make 3D glasses at home after carefully studying them in the cinema. Indeed, nothing complicated at first glance - a cardboard frame and plastic “glasses”. However, 3D glasses have their own manufacturing features.

First, you should understand that “3D glasses” is a conventional name. Conventional cinema glasses with red and blue filters create a stereo effect, not a 3D effect. This effect is based on the anaglyph method. It consists in color coding of the image: red color is perceived only by the left eye (the right one is hidden by another light filter), and turquoise is seen only by the right eye (the left one is hidden by a red light filter). Therefore, the correct name for glasses is anaglyph.

The quality of glasses depends on how clearly they separate colors. Ideally, the stereo effect should be clearly visible through the glasses without ghosting.

If the picture in the glasses is very double, then this means that the glasses are of poor quality, incorrectly made or with filters that do not match the color.

It's worth noting that red-blue glasses will only work when viewing 3D movies and stereo images with red-blue color separation. If the image is double in crimson and green, then glasses with the corresponding colors are needed. There are not many films of this color yet (“Coraline in the Land of Nightmares”, “Journey to the Center of the Earth”, “My Bloody Valentine”), so red and blue glasses remain popular.

Let's start the lesson

To make your own stereoscope glasses, You will need the following materials and tools:

• markers of three colors: blue, green and red;
• transparent plastic;
• glasses frame;
• scissors or stationery knife.

Plastic can be taken from a bottle, from a CD box, from badges. The main thing is that it is clean and transparent, without cloudy spots or scratches.

The frame can be taken from old glasses or sunglasses. It is better if it is plastic - it is easier to remove the glasses from such a frame and insert new ones.

Work progress:

1. Cut out two pieces of plastic according to the shape of the frame;

1. Carefully, so as not to break or crush, insert the plastic blanks into the frame;

1. Color the lenses with markers: the right lens - with a blue marker on one side, green - on the other, and the left lens - on both sides with a red marker;

1. Wait until the lenses dry completely.

The glasses are ready!

The paint on the plastic should be applied evenly (the image depends on this). For better quality painting, you should disassemble the marker and squeeze the rod onto the lenses, evenly distributing the paint. You can also use a wide brush.

If the plastic “glasses” fall out, that is, they are thinner than required by the frame, you should lay paper or cardboard along the edges until the lens is fixed. If you don’t have a ready-made glasses frame, you can make it yourself from cardboard. To do this, cut out a wide cardboard strip and bend it in two places so that you get chokes (you need to try it on). Then cut a small triangle in the middle so that the glasses sit well on the bridge of your nose. “Windows” are cut out on both sides for future light filters. The darlings are leveled by the ears.

The filters can be secured with tape or sealed on top with the same cardboard strip with “windows”.

It would be great if you could find ready-made plastic in the right colors. Then all that remains is to cut it to shape and insert it into the frame.

The technology for making glasses with your own hands is really simple, but you need to remember a few features and pitfalls:

1. To obtain a stereo image, you must strictly observe the location of the light filters: the left eye is red, the right eye is turquoise. Otherwise, the effect may not work.

1. The image in glasses may depend on the quality of the photographs themselves or the color rendering of video playback devices. It may be worth setting the projector to produce clear blue and red colors for better results. In addition, when digitizing 3D films, the quality can be greatly degraded, so that the separation between red and blue colors will be almost imperceptible even to the naked eye. In any case, having tried glasses on one object and not getting the desired result, you should not assume that they do not work. You should test the glasses on several photographs or films.

1. It must be remembered that some images for the stereo effect are divided into green and magenta, so standard blue-red glasses will not convey the stereo effect. It might also be worth making some raspberry green glasses and trying them out.

1. Professionally made glasses will still be better than homemade ones. Uniform coloring, smoothness and transparency of the lenses will give a better effect than hand-painted plastic elements.

Virtual reality technology is very popular now, but it is still quite expensive and not available to everyone. Probably everyone has heard about Oculus Rift and its numerous analogues. In this article you will learn how to make 3D virtual reality glasses yourself for free and very simply. And according to my impressions, this homemade product will be almost comparable to its expensive analogues. These glasses are called "Google Cardboard". So let's get started.

You will need

• cardboard or paper;
• scissors;
• stationery knife;
• paper glue;
• printer;
• 2 flat-convex lenses;
• Velcro for clothes;
• smartphone.

Instructions for assembling Google Cardboard virtual reality glasses

1 Preparing the template for Google Cardboard

First of all download the archive with a template for future virtual reality glasses(in section "Do it yourself" at the very bottom of the page). Let's unzip it into a separate folder. File Scissor-cut template.pdf will contain the pattern we need. You need to print it on a printer at a scale of 1:1. It will fit on 3 A4 sheets.

Google often improves its developments, including Google Cardboard. Because of this, the files in the archive may change over time. Therefore, I am attaching it for printing on a printer.

2 Template cutting for virtual reality glasses

Now carefully glue the pattern onto the cardboard. When the glue dries, you need to cut out all the parts along solid lines.

3 Corps formation 3D glasses

We bend the parts along the lines marked in red in the instructions. We insert flat-convex lenses with a focal length of 4.5 cm into special holes. We connect everything as shown on the pattern. We insert the lenses into the holes for the lenses, with the flat part towards the eyes. It should look like in the photo.

The most important detail is the correct lenses. They must be exactly the same, and the focal length must match the distance from your eyes to the smartphone screen. The choice of lenses determines your comfort and the quality of your experience using virtual reality glasses. The downloaded archive contains detailed information on the selection of lenses and focal length, check it out.

4 3D application for smartphone

Now you need to download smartphone applications that support 3D technology. If the smartphone is on the Android operating system, then applications can be downloaded, for example, from Google Play, searching for the keywords “cardboard”, “virtual reality” or “vr”. Typically, the icons of such applications contain a stylized image of our 3D glasses.

5 Improvement of glasses virtual reality

We glue Velcro on the top of the glasses so that the smartphone compartment can be secured when closed. It is also advisable to make rubber straps so that the glasses can be secured to the head. From the photo you can see how it should look in the end.

6 Virtual reality glasses in action

We launch any of the downloaded 3D applications and insert the smartphone into the special place designated for it in the resulting glasses. Close it and secure it with Velcro. Now, looking through our homemade glasses, we can completely immerse ourselves in a virtual three-dimensional world.
