EPIC will be the first dance event in the world to feature 3D holograms, a concept that sounds like something straight out of a Star Wars movie.
However the holographic display method being used today actually comes from an 1860’s illusion technique known as Pepper’s Ghost (so named after the man who invented it, John Henry Pepper).
How does it work exactly? At EPIC, a projector will be suspended above the stage and will point directly downwards. Its projections will hit a ‘bounce screen’ that is laid flat on the stage floor, out of view of the audience.
The bounce screen acts like a mirror (the original Pepper’s Ghost technique actually used a mirror), and will ‘bounce’ the projections onto a plastic film screen located above at a 45° angle. That will make the videos seem as if they are floating in mid air and the result is something pretty extraordinary.
For the past two hours a two-man crew from a company known as Musion, has been building the holographic film screen. To ensure the images are as perfect as possible the plastic film has to be completely taut with no slack whatsoever. However despite being very strong the film is also very fragile so it’s a delicate process.
