Einstein discovered the laser. Since it was invented by human beings, it has become more and more popular! Although most people are not directly exposed to laser, laser products are gradually becoming a part of our daily life. Laser carving and cutting to create a variety of great works of art is one of the many uses of laser.
In other words, laser therapy uses the physical denaturation of lightning melting and gasification during laser irradiation to achieve the purpose of treatment. The content carving model is developed by AutoCAD, CorelDRAW, Photoshop, AI and other software. The things you want to carve are created directly with computer software. You can take our laser engraving software with you.
In the 21st century, with the increasingly extensive application of laser technology, the development of electronic technology and the popularization of computer aided design, two independent technical fields overlap and merge into "laser engraving technology". Laser has become a kind of carving tool. The carving objects are not limited to the types mentioned above, but also glass, steel, plastic and other carving methods.
Laser engraving is divided into external engraving and internal engraving. Compared with the external carving, the internal carving method is more difficult, and the artistic effect of the finished product is better. Laser carving creates visual and tactile artistic images in specific spaces, and uses various plastic or hard materials that can be molded and carved to reflect social life and express people's wishes.
Creativity is everywhere. As you can imagine, nothing is impossible! The laser engraving and cutting machine has created and processed a piece of ordinary material, which has shown great artistic influence in every corner of our daily life. This is the most common laser application! So how does laser processing create all kinds of beautiful patterns?
Ink animation checked 6 times
A series of hand-painted Chinese style animations of five ice and snow rings show the progress of the Winter Olympics. Gao Yanmei, the leader of the ink painting animation group and professor of the New Media Art Advanced Innovation Center of Beijing Institute of Graphic Design, said that the ink painting animation group was based on nearly 1000 paper effects and nearly 30000 digital animations. Finish after multiple views.
"How to make the works more complete, fashionable and modern, with Chinese flavor? It is very difficult to show the world the unique artistic concept and aesthetic style of Chinese people," said Gao Yanmei, who gave the characters texture and joy based on the original technical design of sports characters. The traditional form Ink animation team tested the power of a two handed technique - painting on rice paper and ink, and digital ink and brush.
In order to draw freehand on nearly 2000 pieces of paper, the team used the "perception of meaning" technology of Chinese traditional culture to capture the internal "attachment" and "goodwill". Character fragments in motion. Follow the action of the character and use calligraphy. Lines become the expression of life. In order to improve production efficiency, the team used brush painting experience and reference effects to apply digital ink, and improved the speed of paper and digital contact through calligraphy, solid lines, trunk lines and interruptions. Display the innovation of refreshing effect of Chinese mascara in a fully digital way.
In order to make a good impression at the beginning of the animation preview, the team tried to draw the first animation frame and an important part of the first human character on rice paper, and completely digitized the record. Photo. Through further technical optimization, the moving characters will be transformed into animation effects that emphasize the texture of digital calligraphy. From "acceleration" to "charm", high-quality artistic expression will be presented with Chinese digital ink.
In just over 80 days, the team produced 6 pre and post animation hand drawn previews, tested nearly 1000 paper effects, and drew nearly 30000 digital animation images.
Variable digital lighting effect
The opening ceremony uses outdoor giant "ice maker" lights, flashing "five ring ice", augmented reality snowflakes and other digital lighting effects to create a multi-dimensional visual effect. At the opening ceremony, Sha Xiaolan, the chief lighting designer, said that many art equipment and technologies, such as real-time photography and naked eye 3D photography, are world first, which can be said to be a huge and complex project. On the ice of reality. And snow effect.: Innovative digital technology. In addition, the visual effects project includes 17 process references, including more than 5800 seconds of digital content, about 290000 images, and about 2430 hours of machine display. Ground display (ice surface) and vertical screen resolution. 15 Giant screen.
At the opening stage, the artist's stage presents a huge light and shadow effect on the floor, creating a huge visual impression of the "skating rink". Every second, the floor of the screen changes according to the program settings, ethereal or romantic, with a unique aesthetic sense of the screen.
During the production and installation of the main screen, many problems were discussed, such as software and hardware, flow control, etc. Based on the creativity of CEO Zhang Yimou, we will continue to optimize all parts of the program. At the opening ceremony, Wang Zhiou, director of visual effects, said: "First, visual effects will digitize all creative content, so that all the main creators, directors, actors, etc. can immediately improve the landing and reproduction of creativity; many hardware parameters, such as color temperature, resolution, installation materials, are used to detect the effects of ambient light and ice structure. Snow is as close to the peak as possible. Third, the design research will continue to achieve a 360 degree panorama, and will install angles and mechanical equipment for the on-site and front audience.
LED display can withstand extreme conditions
How did the Five Ring Snow and Ice "come into being"? The Haitian high-tech company Liade continued to manufacture and install the bottom net, ice trap, icicle, north-south bracket and reading system for the opening ceremony of the Beijing Winter Olympic Games. "Portrait vision is created by combining laser and IceCube 3D images," said Li Jun, president of Liad Group.
The ice is 22 meters long, 7 meters wide and 10 meters high. It is composed of LED screens. The fifth ring itself is also an LED display screen. When it is turned on, a laser beam radiates an ice cube from the scene on the fourth floor to "shape" it. The five rings under the sculpture "slowly rise, and the LED screens on the four sides of the ice block slowly fall, reproducing the stereoscopic visual impression of" spitting ice balls ". Gradually, five rings were formed.
In addition to ice cubes, the nearly 60 foot ice falls are also made up of LED screens.
The outdoor lighting of the opening ceremony of the Beijing Winter Olympic Games brought a shocking visual feast to the audience. It consists of 46504 identical boxes, with an area of 50 square centimeters and a total area of 11626 square meters. It is the largest 3D LED platform in the world.
Although its surface is large, the external screen is very "mobile". For example, in the movie "The Yellow River Water Falls from the Sky", the water flows down from the falling place of the ice, and the waves on the ground seem to radiate layer upon layer, which is amazing. † Wang Dingfang, the project manager of the opening ceremony of the Winter Olympics of Liad Group, said that the image of the whole region can have a three-dimensional effect on the eyes. In addition, there is a circle of "black squares" around the terrain picture, which is actually a picture. For example, when snowflakes fall, they will rotate in this area, and the visual effect is like snowflakes flying. The floor screen is also equipped with an interactive motion capture system. The built-in camera of "kondonde" bird's nest can capture people's actions on the ground in real time, which not only improves the picture sense, but also makes the picture more realistic.
Several exhibitions at the opening ceremony showed the whole. Liu Haiyi, CEO of the Winter Olympics Project of Liad Group, said that the entire LED screen reading system is responsible for displaying four 8K reading media, the ice screen is responsible for displaying two 8K broadcast media, and the ice block is responsible for displaying 8K can play discs. The transmission control system synchronizes the video output of multiple users when the error does not exceed 2 frames.
The whole planning cycle for the opening of the Beijing Winter Olympic Games includes the summer and rainy season from July to August in Beijing, and the winter and snow season from December to February next year. Not only solar radiation and rain, but also extreme erosion caused by sand storms in autumn and ice and snow in winter? According to Li Jun, based on the complex indoor and outdoor environment, a large LED display module is used for the opening and closing ceremony design, which is a high-quality waterproof, anti-skid, colorful and highly stable LED display module. It is developing vigorously. Suitable for outdoor use Under extreme conditions such as low temperature and freezing point, LED display screen and its components meet IP66 protection standard, which can prevent foreign matters and water from completely entering electrical equipment and strong water flow.
