The League of Legends World Championship and it’s opening ceremony are an enthralling spectacle when experienced in-person alongside tens of thousands of rabid, cheering fans. But with a vast majority of the audience watching from home, what could be done to make their experience just as powerful?

With 2017's finals taking place in the iconic Beijing National Stadium, also known as the "Bird's Nest," there was an opportunity to leverage the character of the massive, 80,000 capacity arena to bridge the worlds of traditional sports and League of Legends.

Using live augmented reality, we brought a life-sized Elder Dragon into an Olympic stadium.

To deliver maximum fidelity, a team of artists from around the world worked for 6 months to create a life-sized scaled model of the Elder Dragon that could be superimposed into the live broadcast and viewed without the assistance of any additional hardware.

The final animation had to:

- Incorporate real-time 3D masking that enabled the Dragon to appear behind the stadium as it entered and left

- Cast accurate soft shadows on geometry the size of a stadium

- Utilize real-time color correction to match exposure and contrast of the cameras and environment

- Synchronize with multiple tracking cameras

- Operate on multiple rendering engines to allow for different camera angles and shots of the Dragon

- Synchronize with the musical performance from the opening ceremony

The Elder Dragon was a hit with League of Legends fans, driving nearly 400,000 conversations on Facebook that day, trending alongside #Worlds2017 in two dozen countries on Twitter, & racking up millions of views though multiple videos on Youtube .

This spectacle contributed to driving a record-setting viewership of 57 million fans who tuned in to watch the League of Legends World Championship Finals across streaming platforms that included Youtube, Twitch, Afreeca, DouYu, and HuYa.
