3D technology guided by double cables was used for the first time at the 19th Asian Games

Famous for its height and speed, the ebb and flow of the Qiantang River is undoubtedly a unique sight and a traditional tourist attraction in East China’s Zhejiang Province. Every year, giant waves crash onto the banks of the river near the city of Haining.

As the opening of the Hangzhou Asian Games approached, artists intensified their rehearsals for the final stage. Hangzhou Olympic Sports Center Stadium, venue of the ceremony opening.

Dancing in the air as a couple using steel ropes and pulleys is a challenge for young performers.

“We are faced with the inability to control the cables. Since we normally train on the ground, it is a huge challenge for us to complete such a performance, which requires two dancers to dance with steel cables under 3D technology for the first time,” said Huang Chendi, the opening ceremony dancer of the Hangzhou Asian Games. ” said.

Unlike traditional dance perform graceful, flexible and versatile movements Strong muscular support from two dancers is always needed in the air.

“When we are tired from walking or climbing a mountain, we put our feet on the ground for support. But when we are in the air, we have to keep the muscles very tense throughout the performance, apart from getting some force from the two thin cables,” he pointed out. Li Yanchao is a dancer at the opening ceremony of the Hangzhou Asian Games.

Each artist must be lifted from different directions by four steel ropes to complete the couple’s dance by flying freely in the 3D space of the entire venue. They can achieve 360-degree rotations with wire-guided 3D technology and programmed wire feeding device. The innovation is used for the first time in a large sports hall, rather than being used in a limited area on stage.

“Normally we use a single-line cable that can only be raised and lowered vertically in a limited area. With double cable-guided 3D technology, however, we can operate it 360 degrees as we wish. For example, in length, width and height in an equal area, not just up and down to complete performances and operations , we can also make movements horizontally to all corners and in all directions,” he explained. Ma Jinming, cable engineer at the opening ceremony of the Hangzhou Asian Games.

By presenting tidal images of the Qiantang River, the design team hopes to demonstrate the integration of man and tide, power and beauty, art and technology at the opening ceremony of the Asian Games.

“Taking the tidal waves of the Qiantang River as the background, whether it is cross tide, line tide, tide tide, fish scale tide and other various forms of tides, I think it represents the different positions and ways of each of us against the waves of our time “We are trying to fight,” he said. Meng Ke, general director of the games’ opening ceremony.

The 19th Asian Games, scheduled for September 23 to October 8, will be held in Hangzhou and five other cities in eastern China’s Zhejiang Province – Ningbo, Wenzhou, Jinhua, Shaoxing and Huzhou. The Games will host 481 events in 61 disciplines in 40 sports, to be held in 54 competition venues.

It will be the third Asian Games to be held in China after Beijing 1990 and Guangzhou 2010.
