What are the technologies that help “dragons fly” in the opening ceremony of the 31st SEA Games?-Information Technology

This is the first time Vietnam has qualified for technical equipment and the support of new technology in the world’s most modern art expression.

At 8pm on May 12, the opening ceremony of the 31st SEA Games hosted by Vietnam took place at My Dinh National Stadium (Hanoi). In it, there is a dragon flying performance with the application of modern technologies.

TV viewers can admire the vivid image when the dragon flies from the center of the stage floor (8,000m²) of My Dinh Stadium, curling and circling around the stage and all over the field. Meanwhile, with the naked eye, the audience on the field only sees the dragon on the stage’s screen (800m²).

According to the press release of the 31st SEA Games organizers, this is the first time that Vietnam has qualified for technical equipment and the support of new technologies in the performing arts, performance and performance technology. Square, mass, proactive and showing the preeminent performance of projection technologies:

– Graphics (Mapping);

– Virtual Reality (Virtual Reality – VR);

– Augmented Reality (AR);

– Mixed Reality (MR – Mixed Reality);

– Extended Reality (EX).

So how are the above technologies defined?

Mapping: Mapping projection technology is a technique that uses light and images to create 3D effects on an uneven surface, while helping image blocks in three-dimensional space interact from real objects. Mapping brings impressive effects as well as easily conveys the message, attracting attendees.

Virtual Reality (VR): Is a simulated experience that may or may not be completely different from the real world, in other words creating a simulated environment. This environment is designed by humans through specialized software, and displayed on TVs, phone screens, computers or through virtual reality glasses (Oculus Rift, HTC Vive, Playstation VR…).

Augmented Reality (AR): While VR brings users to a virtual world completely separate from reality, AR technology helps to bring graphic images (digital information) into the real world for people to see. by naked eye. AR puts the real world at the center but enhances other digital details.

Mixed Reality (MR): Covering the two concepts of VR and AR, helping people to explore and connect with virtual and real environments seamlessly. Virtual objects will be located in the real world through use space and coordinates, so that when the user moves towards the virtual object, they will be larger and vice versa. Moving around will allow users to interact with virtual objects as if they were in the same place. Or can be simply understood, mixed reality helps to establish the human sensory state in the real environment and increase the virtuality.

Augmented Reality (EX): A term that refers to all environments that combine real and virtual, and human-machine interactions created by computer technology and wearable devices. The term covers VR, AR, and MR, as well as all other future “virtual reality” that technology may bring.

Even the flock of flying storks made many people watching the opening ceremony of the 31st SEA Games through the TV screen to admire.
