CCTV News: At the National Day party last night (October 1), the fireworks performance brought us surprises and shocks. So where does the fireworks creativity in the night sky come from? So how to achieve it? Let’s listen to the introduction of the chief designer of fireworks Cai Guoqiang .
Fireworks Chief Designer for the 70th Anniversary of National Day Cai Guoqiang: Beijing is different from other places. It is an ancient capital, and it is very clear from east, west, south and north. Chang'an Street can open the city like a gate. When the evening party was announced, it was best to be able to use Beijing’s momentum and its pattern to feel a historical sense of time. The sense of time means that there must be enough space and enough space to express the sense of time. The light columns rose one by one, and it should be like Dongdong Dongdong and Dongdong, and ran down the square, and then all got up again. Its sense of ritual conveys the solemn and sacred effect that it conveys is generally impossible to replace or do in other cities.
70 light columns present solemnity and ritual sense
From the 29 running footprints of the Beijing Olympics, to the doves of peace flying on the 60th anniversary of the National Day, to the 70 light columns of light columns of this party, Cai Guoqiang used fireworks art to present a different sense of ritual. During the party, fireworks and dances show waves of wheat rolling together at low altitudes, and in high altitudes, the live performances are pushed to climax again and again with the rhythm of the music.
National Day 70th Anniversary Party Fireworks Chief Designer Cai Guoqiang: Music is the whole performance with music, let's change it to the time code. Then when the fireworks are in the air, when the sound of "bang" is about to come out, the music time will be counted down in advance, because when a bullet moves upward, it will walk upwards by an average of 40 meters in one second. If you want to reach 200 meters, you have to walk for several seconds, and then explode. If you "bang", it has been blown up in the air for a long time and have not received that rhythm, but this time code knows how to chase someone upside down in advance, and call it out in advance, and the sound can be blown out in the air. The other one is fast-acting type, which is immediately sprayed. It is also stepping on the music point, dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy dy Then all of these are controlled by computers, so the most important thing for our entire fireworks is to have a programming.
Cai Guoqiang introduced that unlike other performances, since fireworks are consumables, in order to achieve the final presentation effect, there is no way to present 100% during all drills. The first two concentrated drills were simulated using electronic programming, and the last concentrated drill was only set off 30% of the fireworks.
National Day 70th Anniversary Party Fireworks Chief Designer Cai Guoqiang: In addition to this grand and grand sense of ceremony, I hope to convey more freedom, more lively, and more down-to-earth lively. When it is 100%, if its design and its quantity are powerful enough, the fireworks present a feeling that it has completely left your design, it is talking by itself, and it is expressing itself as life.
