Accompanied by melodious music, hundreds of performers hold long green fluorescent rods and form a concentric circle in the center of the venue. Music transformation, long rod rhythm, integrated with ground large screen special effects; The audience held their breath and waited for the opening of the Winter Olympics... Such scenes not only appeared at the opening ceremony of the Beijing Winter Olympics, but also were staged in advance thousands of times in the "big abacus" behind the opening ceremony. On the evening of the 4th, the world's attention once again gathered at the National Stadium "bird's nest", and the Olympic light once again shone in the Millennium ancient capital. The successful opening ceremony of the Beijing Winter Olympics excited Ding Gangyi, director of the digital performance and Simulation Technology Laboratory of Beijing University of technology. Over the past two years, Ding Gangyi led the virtual simulation team of Beijing University of technology to provide scientific and technological support for the opening ceremony of the Winter Olympic Games by using the intelligent creation, editing and rehearsal integrated service platform. "We use three-dimensional simulation technology to simulate the whole process of the opening ceremony of the Winter Olympic Games, and carry out an all-round 'troop arrangement' for all elements such as actors, spectators, lights, music, fireworks, Olympic torch and even broadcasting slots. This platform is like a film rehearsal system to help the director team intuitively understand the overall effect of the program." Ding Gangyi said. The total process time, the current link time and the time of subdivision steps are combined with realistic character details, environmental presentation and sound and light effects... Through the large screen of the simulation system, you can not only watch the performance effect from multiple perspectives, but also see the "capillaries" in the performance design - the time control accurate to the second level and the point layout detailed to the centimeter level, Ensure that "the right element appears at the right time". "We integrate the creative details and even imagination of each team in the opening ceremony into one actual effect in the system, so as to demonstrate different schemes. All the effects presented by the system, such as the number of pole swings and the walking distance of characters, should be consistent with the actual performance effect." Ding Gangyi said that with the help of the simulation system, the "optimal solution" of each link of the opening ceremony in the ideal state can be found, and then the scheme can be continuously polished according to the actual rehearsal, so as to greatly reduce the trial and error cost in the real performance rehearsal. Ding Gangyi used the word "abacus" when talking about the role of the intelligent integrated service platform for creation, composition and rehearsal in the planning of the Winter Olympic opening ceremony. "The planning office, the ceremony office, the director team and the technology department all need to come to us. When all parties put forward their needs, we will 'calculate carefully'. During the preparation process of the performance, each team will have new ideas almost every day, such as changes in the number of programs, changes in music and movement adjustments. The 'calculation' keeps playing. Sometimes a small modification will 'pull one hair and move the whole body', but it should also be based on The fastest speed is synchronized in the system and come up with the latest solution. " Ding Gangyi said. "The biggest difficulty of the opening ceremony of the Beijing Winter Olympics is that each program needs to completely couple music, dance beauty and ground screen effects. However, since these three elements are designed by different teams and are basically new creations, they need to be combined together in the simulation system and adjusted and simulated again and again. Multiple elements need to be modified at the same time, which is sometimes difficult to find Out of the 'main contradiction'. " Ding Gangyi said that through the hard work of the team day and night, we can ensure the continuous output of the "computing power" of the "abacus" and find the "Crux" in the shortest time. In 2008, the grand opening ceremony of the Olympic Games held by the "bird's nest" amazed the world. At that time, Ding Gangyi led the virtual simulation team to participate in the technical support service of the opening ceremony, and designed the number of people, points and movements for 1000 people. In 2022, Beijing, the "city of double Olympics", opened a simple, safe and wonderful ice and snow event for the world. The amazing opening ceremony once again branded the scientific and technological footprints of the team. From summer to winter, Ding Gangyi, as a "double Olympian", said: "in the past 14 years, the scientific and technological strength of our country has advanced by leaps and bounds. What remains unchanged is everyone's pursuit of a happy life." Just after the opening ceremony of the Winter Olympic Games, Ding Gangyi led the team to quickly put into the intense work of the closing ceremony of the Winter Olympic Games and the opening and closing ceremony of the winter Paralympic Games Xinhua news agency, Beijing, February 4 (reporter Zhang Xiao) - in the "five ice and snow rings" chapter of the opening ceremony of the Beijing Winter Olympic Games, there is an "ice cube" presented in the form of ink animation. How can this ingenious combination of Chinese culture and digital technology be realized? According to Professor Gao Yanmei of the advanced innovation center of new media art of Beijing Institute of printing, on November 12, 2021, the digital ink animation innovation design team of the school received an important task: to present the theme animation of the "ice cube" movement of the opening ceremony in the way of "ink art + digital technology". According to Director Zhang Yimou's requirements of "giving characters traditional texture and life spirit in the form of ink and wash", the team set the human shape of the sports events of the previous winter Olympic Games represented in the animation content, and tried to carry out visual depiction in the form of rice paper ink hand painting and digital ink brush. Finally, after drawing the human figure with a brush on nearly 2000 rice paper and practicing calligraphy with a brush on more than 10000 paper, the team used the traditional Chinese method of "viewing images and taking ideas" to extract the internal "look" and "wonderful meaning" of the sports human figure. In January 2022, according to the observation opinions of the International Olympic Committee and the modification requirements of director Zhang Yimou on "highlighting the texture of calligraphy and writing", the team strengthened the "sense of power" and "sense of writing" in the production of ink figure. After testing nearly a thousand paper effects and drawing nearly 30000 frames of digital animation, the digital brush is given the "internal force" of the brush words "strong backbone and flying state", while ensuring the high fluency of sports dynamics and the full embodiment of sports spirit in the animation. According to Gao Yanmei, the main members of the team are "Post-00" graduate students. They have worked hard for more than 80 sleepless nights to participate in animation design, and have made seven versions of adjustments successively. We are very honored and proud to be able to use what we think and learn to help the animation design of the opening ceremony of the Winter Olympic Games and integrate Chinese culture into the classic scene with "Ink Art + digital technology" in front of the world.
