Now 3D movies and animation are becoming more and more famous. Mysterious and dreamy effects with shocking music make you feel amazed. You can say that it has brought us audio-visual enjoyment. Read this article to learn more about it. If you want to make your stereo video or convert ordinary 2D movies to 3D, you can also find the answer in this article.

What is 3D and What It Can Do

Three-dimensional is something with width, height, and depth. Our physical world is 3D. Because of the depth perception of our eyes, we can perceive the stereo image. Moreover, it has broken the boundary between the virtual and real world and brought us an amazing experience. It can bring people a realistic visual effect, which can be used in many fields, including video games, movies, architecture, illustration, engineering, and commercial advertising. You can also use three-dimensional printing to make artificial organs, artificial limbs, building models, toys, etc.

How to Make A Stereoscopic Video

If you like the realistic vision brought by stereo effects, you can also make 3D videos at home. AnyRec Video Enhancer is a professional tool to convert ordinary video to 3D with four modes including anaglyph, split screen, depth, and switch left-right, but also that it has many other special functions, such as high-grade resolution, optimized brightness and contrast, removed video noise, and powerful editing functions.

1. Anaglyph

Overlay two identical images with different colors, similar to ghosts, to produce a steric effect when viewed through the corresponding color filter.


2. Split Screen

Divide the video into two pictures to feel different angles, it is divided into side by side and top and bottom methods.

Split Screen

3. Depth

The Depth of 3D is the way to adjust the distance and height of the image. You can use this method to make the things in the picture give you a more realistic effect.

The Common 3D Products You Know

1. 3D Film

A 3D film is a film made for the audience to create a real environment, which usually requires wearing special glasses to watch. A three-dimensional movie is a kind of movie that can produce a stereoscopic effect by using the angle difference and convergence function of the human eye. The main technologies used in 3D movies are as follows.

3D Film
Displaying Technology
Anaglyph In stereoscopic photos, two images are superimposed in the additional light setting by two filters (one red and one cyan). In the subtractive light setting, two images are printed on white paper with the same complementary color.
Polarization systems Overlay the two images on the same screen or display them through different polarization filters. Since each filter passes only light with similar polarization and blocks the light polarized in the opposite direction, each eye sees a different image.
Active shutter Its working principle is to let the left eye see the image first, then let the right eye see the image, and quickly repeat the process so that the interruption will not interfere with the conversion of the perception fusion image of the two into a single 3D image.
Interference filter technology Glasses that filter out the very specific wavelengths allow the wearer to see a 3D image.
Autostereoscopy Glasses are not required to view stereoscopic images, but the audience must sit at a very narrow-angle almost perpendicular to the screen so that the left eye can see one of the two images and the right eye can see the other.

2. 3D Glasses

Early 3D movies used red and green (blue) glasses, and lenses of different colors filtered out the corresponding colors so that we could see different images. But long-term wearing will make eyes tired. The current 3D glasses are classified as follows:

3D Glasses Technology
IMAX system It is also called linear polarization lens, left eye horizontal polarization, and right eye vertical polarization. The left and right glasses only accept the images of their respective directions, and stereo vision is generated through the combination of the brain.
X-PanD time-sharing system The pictures of the left and right eyes are alternately played, and the left or right eyes corresponding to the glasses are alternately transparent and opaque through electronic signal synchronization. The playing image is the same as the frequency control of the glasses, so you can see the three-dimensional image.
RealD spectroscopic system It is also called the circularly polarized lens. At present, it has become the mainstream of 3D TV and the largest proportion of cinemas.
Dolby color separation system New technology improvement of red-green (blue) lenses. But the cost of glasses is high. At present, few cinemas use such glasses.

3. 3D Animation

3D animation can simulate real things in this way, regardless of time, place, space, and other conditions. Three-dimensional animation can be used for special effects production (such as explosion, smoke, rain, etc.) of advertisements, movies, and TV dramas, special effects (collision, deformation, illusory scenes or characters, etc.), advertising product display, title flying, etc.

4. 3D Television

3D Television brings visual enjoyment to the audience by adopting technologies such as stereoscopic display, multi-view display, 2D plus depth, or any other form of three-dimensional display. Most modern 3D TVs use active shutter systems or polarized systems. Some are auto-stereoscopic and do not need glasses.

Displaying Technology
With filter/lenses
1. Anaglyph 3D – with passive color filters

2. Polarized 3D system – with passive polarization filters

3. Active shutter 3D system – with active shutters

4. Head-mounted display – with a separate display positioned in front of each eye, and lenses used primarily to relax eye focus.
Without lenses Auto-stereoscopic displays(Auto 3D)
others Holography, Volumetric display, and the Pulfrich effect
