HoloVizio fulfills true 3d criteria of 3D displaying

No glasses needed, the 3D image can be seen with unassisted naked eye

Viewers can walk around the screen in a wide field of view seeing the objects and shadows moving continuously as in the normal perspective.
It is even possible to look behind the objects, hidden details appear, while others disappear (motion parallax)

Unlimited number of viewers can see simultaneously the same 3D scene on the screen, with the possibility of seeing different details

Objects appear behind or even in front of the screen like on holograms

No positioning or head tracking applied

Spatial points are addressed individually
