1. Digital Lights
The five Olympic rings slowly rise in the Bird's Nest and fly into the vast night sky; ancient Chinese calligraphy and painting scrolls slowly unfold, presenting the classical mood of ink painting; on the ancient Silk Road, the huge wooden boat rides the wind and breaks the waves - these stunning visual effects are outlined by the Bird's Nest's magnificent lighting The Bird's Nest's magnificent lighting outlines all of these stunning visual effects.
In the opening ceremony of the Olympic Games, the Bird's Nest interior of more than 600 competition lighting was abandoned, Zhang Yimou chose to bring their own lighting fixtures. Technology has entered the digital age, and lighting effects have transitioned to digital lights. This emerging lighting effects make the scale and imagination of the stage effects of the opening ceremony of this Olympic Games to the extreme.
The Olympic Games used in the digital lights of a kind: PG lights, that is, high-brightness projection lamps, the use of optical projection principles, the use of high-brightness light source, the content of the negative in the form of full-color projection to the ground at night can form a very visually impactful picture effect. In the opening ceremony performance, the large scroll in the center of the venue that always runs through the performance, as well as the animation of the evolution from ancient times to modern times shown on the scroll one after another, are all projected to the center of the venue by this PG light after pre-production. The ancient simplicity of the black and white contrast of Chinese ink paintings, the splendor of Western oil paintings, and then the strong colors of Impressionism are all presented by relying on this high-tech technology.
2.LED
LED, or light-emitting diode, is a semiconductor solid light-emitting device, it is the use of solid semiconductor chips as light-emitting materials, when the two ends of the forward voltage, the carriers in the semiconductor complex caused by the photon emission and produce light.LED can be directly emitted red, yellow, blue, green, cyan, orange, violet, white light.
In the current Olympics, LEDs have been maximized. The opening scroll opens on a huge LED screen. The screen is 147 meters long, 22 meters wide, is the highest technological content of a huge platform, the top of the laying of 44,000 pieces of LED. LED light and shadow effects and the performance of a close combination of illusory patterns, the audience will be introduced to the dreamlike world. Moreover, the LEDs have been repeatedly tested to withstand the test of actors stepping on them and flooding them.
Rising into the air of the "Fantasy Five Rings", also by 45,000 LEDs on a large network depicted. Even the actor's costume is also full of a LED, with the actor's formation changes, the stage "Bird's Nest" reappeared. Although the entire opening ceremony is very long, but the battery and other scientific and technological research techniques to solve the LED energy problems.
3. Aluminum alloy materials
The opening ceremony, the center of the stage, opened a large hole, a six-story high, about 20 meters in diameter, "Earth" slowly rising from it. So big "Earth" where to hide at first? Originally, this "Earth" is first compressed in the ground, that is, the sphere structure must be flexible. Placed on the ground is oval, was pulled up by the wire above will become spherical.
After the sphere is lifted with the lifting platform, the actors need to perform on the surface of the sphere, so it should have a strong stability after lifting to ensure the safety and effect of the performance. And this all depends on high-tech aluminum alloy light-sensitive materials, so that the "earth" can bend and stretch.
4. Multimedia
In the huge scroll over the "birds" and "whales" free to fly and swim, these and how to do it? Originally, the previous opening ceremony on the use of slide projection technology, and this time the use of multi-phase multimedia equipment. It can use the computer to text, graphics, images, animation, sound and video and other media information are digitized, and then integrated in a certain interactive interface, in order to create a "Bird's Nest" at the top of the thousands of square meters of the bowl side of the shape of the screen, showing a "whale" from the Swimming in the clear picture, expressing the harmony between man and nature.
5. Digital ignition
Review of the opening ceremony of the Olympic Games, the most surprising thing is that the fireworks composed of 29 huge colorful footprints from the Yongdingmen, through Tiananmen Square, all the way north along the central axis, and finally arrived at the Bird's Nest National Stadium.
These 29 fireworks footprints, opened the 29th Olympic Games, symbolizing the modern Olympic Games step by step towards Beijing, into the Bird's Nest. The 29 big footprints of the ignition using a computerized system control, the use of digital ignition. This technology ignites all the fireworks in a very short time and ensures that the fireworks can cross 3.5 kilometers in just a few seconds. In addition, there are 22 launching points in the dragon shaped water system next to the Bird's Nest, and after digital control by computer, all the fireworks can be shot up to the sky one after another, so that the fireworks as a whole look like a huge dragon in the air. Although the use of traditional fireworks, but after the digital ignition, fireworks have produced new changes, resulting in different visual effects.
