Childish Gambino mesmerizes fans with real-time animation

By Andy Blondin

In 2016, singer/rapper Childish Gambino blew audiences away with his Pharos show, where projections of futuristic imagery and animation inside an enormous dome surrounded the audience and performers throughout the concert. To complete the technological experience, the concert spawned a 360-degree video and a VR companion app.

The show was such a hit that Childish Gambino, aka Donald Glover, set out to do it again in November 2018, this time with a fully interactive real-time system powered by Unreal Engine. The 2018 Pharos experience, which combined custom lighting, smoke, a laser show, and a mesmerizing visual experience projected onto the dome’s interior in real time, not only blew away fans but won the team a prestigious VES Award for Outstanding Visual Effects in a Special Venue Project in February, 2019.
To prepare the show, Glover asked 2n Design and Weta Digital to design the system architecture, and also to style a different visual world for each song he would perform at the concert.

Though Glover is known for his commanding stage presence, he wanted to enhance the crowd’s experience and make a truly immersive and memorable show. ”He really wanted to bring the audience into this world and create this experience that everyone has together,” says Austion Woolfolk, Video Designer at 2n. “We're all body-to-body in this 3,000-person dome and we're all in this world, every single piece ebbing and flowing, we're going on a journey together.”

The size of the dome meant that a lot of pixels would be needed on the screen. “We knew we could make a high-quality result, particularly if we went with the Unreal Engine,” says Kevin Romond, Special Projects Supervisor at Weta Digital. “It has so many features related to image quality that we knew that we'd be embracing for this project.”

To display such large imagery across the dome’s surface, multiple projectors were required. The team found a solution in nDisplay, the Unreal Engine utility for creating a seamless visual of a single scene from multiple projections in real time. 

The team calculated that they’d need a 5.4K by 5.4K image rendered by five frame-locked machines powered by NVIDIA Quadro P6000 graphics, then split into a fisheye and sent to 12 projectors. “Using nDisplay to be able to distribute the real-time rendering, and keep the resolution and the frame rate where it needed to be for this project, was key,” says Jeremy Thompson, Art Director at 2n.

Even with such an ambitious creative goal, the team was able to achieve everything they set out to do for the 2018 Pharos concert experience, and more. Woolfolk himself operated the visuals in real time during the concert, interacting with Unreal Engine via a MIDI controller to make the graphics’ timing gel perfectly with the music and other visual effects.

“I'm still fascinated to this day by what we managed to pull off. Tools like Unreal Engine allow us to do that kind of thing.”
