What Is Anaglyph 3D?

3D three-dimensional painting, also known as "three-dimensional three-dimensional painting, panoramic strange painting, panoramic picture-in-picture, three-dimensional painting, raster three-dimensional painting, etc.", there are many types, divided into PP, PET, PS, PMMA, PVC, PE, etc. according to different materials .

3d stereo painting

To understand the principle of 3D stereoscopic imaging, we must first understand the concept of stereoscopic images correctly. The stereo image is popularly used to make use of the two people's visual differences and the principle of optical refraction in a plane so that people can directly see a three-dimensional three-dimensional painting. Things in the painting can either stand out of the picture or be hidden in it. Lively and vivid, giving people a strong visual impact. It is fundamentally different from a flat image. The flat image reflects the two-dimensional relationship between the top and bottom and left and right of the object. The plan view that people see also has a three-dimensional effect. This is mainly reflected by the use of light, shadow, reality, and light-dark contrast. The real 3D stereoscopic painting is based on the principle of simulating the human eye to see the world. It is produced using optical refraction. Three-dimensional relationship. It is a three-dimensional painting in the true visual sense. The emergence of stereo image technology is another technological revolution after the color field replaces black and white in the image field, and it is also the future trend of the development of the image industry.

Grating materials are divided into two categories: lenticular gratings and slit gratings. There are many types of lenticular gratings, mainly including plate, sheet, and mold. The imaging principle is the principle of refraction and reflection imaging with a curved lens. Materials are mainly PET, PP, PVC, PS, PMMA, etc. Because the three-dimensional painting made by the lenticular grating can be viewed directly without lighting, the circulation area is quite large, and the market penetration rate reaches 80%. The slit grating, the linear grating, is the earliest and more mature grating, and is the first choice for the advertising industry to make three-dimensional light box advertising. Slot gratings contain grating radians, but no medium. The advantages are high definition, strong three-dimensional sense, mature products and flexible media. The disadvantage is that it must be lit, so it consumes energy and has a narrow application range. It is mainly used in light box advertising and other fields.

The three-dimensional painting is visually distinct and colorful, and has a strong visual impact, allowing viewers to stay in the scene for a long time and leave a deep impression. The three-dimensional image gives people a real, lifelike character. The characters are ready to come out, they have the feeling of being immersive, and have high artistic appreciation value. Use three-dimensional image packaging companies to make the corporate image more distinctive, highlight the strength and grade of the enterprise, and increase influence! Can better highlight the high quality and high grade of the product. It can also make colorful and colorful three-dimensional wedding dresses and photos, which is one of the latest selling points of the current imaging industry.

The materials for naked eye 3D three-dimensional painting are divided into four categories: sheet grating, sheet grating, slit grating, and film grating. Nowadays, two types of sheet grating and sheet grating are more common in the market. Plate grating ratio fitting is suitable for a small amount of personalized customization, while sheet grating is more suitable for batch consumption. Compared with sheet gratings, the characteristics of sheet gratings are used for the production of large-format 3D stereoscopic pictures. 3D stereoscopic pictures are suitable for long-distance viewing. The stereoscopic effect is very flat and shocking, and has been widely used in many industries. So, which industries are the naked eye 3D paintings applied to? Now, China and India 3D will give you a brief introduction.

1. Special 3D stereo exhibition;

2. Product brand promotion, providing advertising posters for advertising owners;

3. The theme activity of the shopping mall, for the opening of large shopping malls, the scene of promotional activities;

4. Customized stereo images for weddings and celebrations, photography industry, wedding photo studios, and children's photography shops;

5. Theme hotel and venue layout;

6, home decoration, for the crowd of stylish personality taste;

7. City display, designing and decorating cities, municipal landscapes, special area sights, and special commercial streets;

8. Three-dimensional production of big Buddha images in religion and temples;

9. Produce large-scale three-dimensional publicity posters for administrative institutions and enterprises;

10. Custom three-dimensional craft paintings for scenic spots;

11. Brand exhibition, three-dimensional light box, light film display, etc .;

12. Other commercial places, such as: personalized shops, bars, tea houses, clubs, office space, etc.

At present, the application of naked eye 3D stereoscopic painting is becoming more and more extensive. Its application has been extended to all walks of life. Not only has it broadened people's horizons, but it has also largely met the needs of many businesses. effect.

Which grating is best for stereoscopic painting

There is no uniform standard. There are three rules that must be observed from the characteristics of grating materials. These three rules are causal to each other.

Law of size

Thin raster for small paintings and thick raster for large paintings. Generally less than 1.5 mm thick are PET materials. This material is currently the most stable, sheet-like, and the format is generally less than 1 meter. The largest domestic grating is 2m × 3m, which is suitable for large paintings from 0.4m × 0.6m to 0.8m × 1.2m. Such gratings are generally PS materials and are not too stable. The third type is a film grating made of PET material. There is no format limitation, and the size can be used. Usually, it is a 1.2m × 100m format.

Rule of thickness

If you want strong stereo, use a thick grating, if you want weak stereo, use a thin grating. Do you want to reduce the three-dimensional effect? Isn't the three-dimensional sense stronger? No, the three-dimensional sense is the best, too strong will be distorted and uncomfortable. Too weak to have three-dimensional sense. If the drawing technology is not high, can thick grating be used to enhance the three-dimensional effect? Nope. The three-dimensional effect is set during the drawing. The larger the setting is, the larger the setting is. Different rasters should be set with corresponding values, and cannot exceed the reasonable display range of the raster, otherwise the picture will be uncomfortable.

Near-far rule

The stronger the stereoscopic effect, the farther the viewing distance is, and the weaker the stereoscopic effect, the closer the viewing distance is. In other words, the bigger the painting is, the stronger the three-dimensional effect is. You can use a thicker raster to look far. Smaller paintings do not need such a strong three-dimensional effect. Thin gratings can be used to prevent dizziness. The gratings have the best viewing distance. You can choose an appropriate grating to paint according to the viewing distance.

Getting started with three-dimensional painting is not difficult. Most of the regular training is to teach layered hooks and the like, and the battle can be solved in a few hours. This does not make a realistic stereogram.

Generally, the picture will not be shaken on the plane. Three-dimensional painting will not work. There are two biggest problems-shaking and faults. Most people do nt understand, how can the painting shake? The shaking is caused by the afterimage. The three-dimensional painting is not a single picture, but a superposition of multiple paintings. The human eye sees the same picture with different depths of field and generates three-dimensional. Multiple images under the refraction of the grating will produce ghosting at a certain angle, and this ghosting will maintain a certain angle range. When people stand at this angle, they feel dizzy. This double image is also called afterimage. Within a 90-degree field of view, afterimages can appear 4 to 12 times depending on the grating material. Afterimages appear frequently as if the screen is shaking.

The first problem of stereo painting is not to enhance the stereo sense, but to eliminate the afterimage and shake. It is said to be eliminated. Complete elimination is impossible. We can only do our best to reduce the angle of afterimage and reduce the amplitude of shaking. If the drawing technology is not too hard, the afterimages and shaking will increase, and the picture will look intolerable. Routine training institutions and most stereo production companies cannot reduce this slosh. This is also one of the root reasons that many people who learn three-dimensionally give up eventually.

Tomography is another tricky issue for stereo painting. Faults are fractures between three-dimensional layers, with several obvious cracks exposed on the screen. Most training institutions and most stereo production companies cannot solve this problem. This is another reason why many people who learn stereoscopically give up. After a long period of arduous practice and exploration, Deep Company has completely and completely eliminated this problem. The application of inter-layer optimization technology and real-world approximation technology enables smooth transition and seamless connection regardless of the depth of field, how many objects, and the complexity of the picture. Really reproduce reality.

In addition to the above two aspects, which are difficult to learn, the concept of the entire screen is the third difficulty. When I first learned to do stereo, I often did nt know where to start. After long-term practice, the ability to judge the picture will be greatly improved, and the speed of making pictures will be much faster. What sets Deepin apart is that the picture conception and hierarchical division follow the rules of depth data simulation. This method can accurately control the true displacement of each point and each layer on the picture, and then precisely control the three-dimensional intensity of the picture.

The last difficulty is fast and accurate judgment of raster data. Many veterans of the three-dimensional industry cannot come up with a good way to accurately judge the raster data, and print a bunch of raster bars invariably. With the increase of the types of gratings, the size of the gratings is also getting larger. The larger the raster, the worse the data stability. If you make a hundred paintings, you have to measure it 100 times. If you are not sure, you have to measure it hundreds of times. Through a large number of tests on various domestic gratings, you can conclude a unique test technology that can be accurately measured only three times. Get raster data
