Fireworks in the air how to form a flower shape?

3D technology to simulate the process of flowers

Panda Fireworks relevant responsible person said, the spectacular seasonal flowers using the 3D technology, "four seasons fireworks creative, not only to create a classic style of eight kinds of flowers can represent the four seasons with fireworks, show different color petals and stamens, but also the use of color changes, fireworks styling changes to reflect the whole process of flowers and this is an innovation in the history of the world fireworks, no experience".

According to its introduction, as a true representation of each flower blooming process, researchers repeated the test arrangement of visual simulation software, through the support style 3D mapping analysis of the rationality and appearance of the discharge device, after hundreds of tests, finally showing a perfect Narcissus, Clivia, Begonia, Bauhinia, pansy, chrysanthemum blooming process etc..

The responsible person said, "bird's nest", Linglong tower, tower of the fireworks implementation is difficult, in order to make the fireworks show each other perfect flowers open, to ensure the discharge effect, not only by means of the GPS positioning, height gauge, angle instrument, range finder and other high-tech equipment, using high laser the accuracy of aiming tool instrument, precise use of the equipment, technology, to ensure precision of installation position of each of the fireworks products and installation angle, "there is a deviation of MM is not allowed".

Secret

13 thousand square meters of light screen for the nest for color"

Yesterday (10) evening, in the bird's nest, the combination of lighting, fireworks and dance behind the scenes, by the Organizing Committee of the General Assembly carefully designed, composed of 4 million 30 thousand LED lamps composed of 13 thousand square meters of curtain became the core component.

4 million 30 thousand LED lights woven into the screen

In accordance with the performance of the design program, the whole show includes sky fireworks, nest lamp screen, ground dance three parts, which play a role in the bird's nest lantern and fireworks to play a role, it is essential.

"Our vision is composed of a lamp screen as the whole show background wall, when the animation occurs in part by the sky fireworks bear, front of the rostrum by 640 people live performances, dance team, to form an interactive form, three-dimensional sense of strong images. "Party acting executive director Ding said.

Therefore, from the beginning of August this year, the design team began to design, the whole structure of the nest area lighting layout, selection of the West as the main display surface, on-site layout according to the three-dimensional effect of the naked eye 3D. A total of 4 million 30 thousand LED lights, forming a 232 m long, 55 meters high, covering an area of nearly 13 thousand square meters of light screen. The performance of the part of the pure light show more than 3 minutes, and the rest of the more than 6 minutes of the dance show is also the curtain as the background design.

The curtain will become the new Beijing night lights

Because of the double curved surface of the bird's nest and the special steel structure, how to make such a large number of LED lights on the bird's nest structure has become the most important part of the performance design, but also the most difficult part of the construction. According to the person in charge of the project, the light curtain like to look at the big nets from the side, adopt three layer structure, formed by the end of 12 mm diameter cables, the middle wire diameter of 5 mm, the top is LED lamp.
