What constitutes a true 3D show?

Although many people have experienced 3D movies, no one has, up till now, really seen a true 3D theatrical show.  The reason for this is simple.  Until Terracotta Warriors 3D at the Da Yin Theater in Beijing, no producer has ever had the technological tools to provide a 3D backdrop for a stage production.  It is a fact that seeing things in true 3D demands the use of some kind of 3D glasses.  There are claims about the availability of 3D video screens without requiring glasses, but even the latest examples I have seen are blurry, often show objects with double outlines, and can reveal half-decent images only if the viewer is situated dead-center to the screen.  With using either passive or active 3D glasses (active denotes the need for batteries), 3D viewing can be excellent with the use of advance 3D projectors casting the digital images onto a projection screen.  However, this type of 3D projection is ideal only in a darkened cinema but particularly troublesome for a stage show in which the required lighting on stage significantly washes out the projected images.  Other commonly described imitators of 3D projection include holography or another process known as “3D mapping”.  I have worked with both of these phenomena over the past three years and found them to be severely lacking.  Holography, by definition, is not even 3D and all images must be seen frontally in one plane.  “3D mapping” may allow certain images to be seen three-dimensionally, but it only works satisfactorily if the projection surface has architectural qualities while the degree of protrusion of the 3D images away from the screen is quite disappointing. A new dawn has arrived with the installation of the unique, first-of-its kind 3D LED video wall that acts as the backbone of art direction for Terracotta Warriors 3D.  For the first time in world history, a 3D LED video wall with unprecedented qualities acts as the scenic backdrop for a stage production.  Not only does this video screen provide high-definition images, it does so with the viewer wearing non-battery powered glasses with unsurpassed brightness and color saturation, with a positive 3D protrusion of nearly eighty-five percent of the distance to the viewer, and a viewing angle that is greater than 120 degrees.  These are the features that make Terracotta Warriors 3D into a show like no other before it.    We hope that this will become a transforming theatrical experience!
