According to BBC reports, Germany’s Circus Roncalli has become the first circus in the world to use holographic projection technology to replace real animal performances.

In fact, the international circus industry generally encounters animal protection problems. With the advancement of social civilization, the problem of animal abuse and torture reflected behind real animal performances has become increasingly prominent. , and even relevant protection regulations have appeared in many areas, and the United Kingdom has required that entertainment performances involving wild animals be stopped by 2020. Ringling Circus, one of the world's three largest circuses, and Barnum and Bailey Circus have announced permanent closures.

Ever since, Roncalli Circus decided to present it through a new technological method, namely holographic projection. The idea came from Roncalli Circus founder Bernhard Paul also using holographic projection technology when watching the 18th NFL Super Bowl.

In fact, in recent years, the entertainment industry has also expanded the use of holographic projection technology. For example, in February 2019, Lang Lang and Luo Tianyi held a holographic concert; in November 2018, at the "League of Legends" global finals, the K/DA girl group appeared on the stage in holographic form; Prism Entertainment and Digital Domain launched "Teresa Teng·Legend" holographic concert and so on.

It is reported that the Roncalli Circus is currently using a 3D holographic display array consisting of 11 projectors. It is understood that its screen is 32 meters wide, 5 meters high, and has a resolution of 13751×1920.
