If you were asked to design the closing ceremony of the Winter Olympics, what would you do? The steps are as follows:

1, as the first program at the closing ceremony, Lighting continued the story of a snowflake at the opening ceremony and told the theme of "One World, One World". A symbol of cold weather and pure snowflakes slowly descending from the bird's nest, while children symbolizing life and vitality are playing with warm snow lanterns in a snowy field. Among them, lanterns carry the fire of the Winter Olympics, and snowflakes symbolize the participation of every athlete. The combination of the two brings endless warmth to the scene.

2. Subsequently, a huge emblem of the Beijing Winter Olympics gradually took shape, with light and shadow flashing. As the emblem was lit, the whole venue became bright, clear and warm.

3. After the ceremony of raising the national flag and playing the national anthem, the 12 ice cart designed by China Zodiac entered the stadium, and the children boarded the ice cart and slipped out the ice marks on the ice. The whole floor stage system of the opening and closing ceremonies of this Winter Olympics has a building area of about 2 1 1,000 square meters, and more than 40,000 screens constitute a super-large floor display screen of 1 0,522 square meters. It is the largest LED stereoscopic stage in the world at present, and its actual resolution reaches 14880x7248, which is close to 4 8K, which can perfectly present naked-eye 3D effect.

4. Then the special effects house returned again, and countless red ribbons flew into the Bird's Nest from all directions, decorating the snowflake torch platform into a huge red Chinese knot. Giant Chinese knots are generated by digital AR (Augmented Reality) technology. AR can show virtual objects that don't exist in the real world, and form ultra-high and fine realistic visual effects. It really seems that there is a huge entity Chinese knot hanging in the sky. The track of the ice car sliding in the stadium gradually changed, forming a bigger Chinese knot symbolizing auspiciousness and unity.

5. In the Bird's Nest Stadium, Shang Feng team used UE4 virtual camera stream real-time rendering technology to tightly surround the giant Chinese knot up to 40 meters in the air with a solid torch. The accuracy of Chinese knot model, the details of material texture and the volume of real-time rendering are unprecedented in Dou Shi.
