3D displaying can be crucial in many modern applications that use 3D models, volumes or otherwise benefit from 3D information. Also, future visual entertainment can not stop at 2D displaying. In this paper, we describe the HoloVizio true 3D display system. The patented HoloVizio technology uses a specially arranged array of optical modules and a holographic screen. Each point of the holographic screen emits light beams of different color and intensity to various directions. With proper software control, light beams leaving the pixels propagate in multiple directions, as if they were emitted from the points of 3D objects at fixed spatial locations. We show that the direction selective light emission is a general requirement for every 3D system and the advantages of light field reconstruction over the multiview approach. We describe the 10 Mpixel desktop display and the 50Mpixel large-scale system. We cover the real-time control issues at high pixel-count systems with the HoloVizio software environment, give solutions for natural content displaying, and describe concrete 3D applications developed in the frame of European projects.
