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.
3D Video Visualization on the Holovizio¿ System
2008 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video, 2008
The visualization of 3D content is an increasingly important issue as computer graphics applications, computer vision methods and display devices evolve rapidly. As a part of this 3D evolution, fields related to 3D video have also advanced, but displaying high quality large Field of View (FOV) 3D videos in real time still pose a considerable challenge. The HoloVizio™ system is a high quality continuous view 3D display that is capable of displaying large FOV 3D data. In this paper we present the 3D video playback capabilities of the HoloVizio™ system, in connection with recent applications. We focus on practical 3D representation formats, and their usability in the 3D acquisition-transfer-display chain.

Recent results in rendering massive models on horizontal parallaxonly light field displays
2009
In this contribution, we report on specialized out-of-core multiresolution real-time rendering systems able to render massive surface and volume models on a special class of horizontal parallax-only light field displays. The displays are based on a specially arranged array of projectors emitting light beams onto a holographic screen, which then makes the necessary optical transformation to compose these beams into a continuous 3D view. The rendering methods employ state-ofthe-art out-of-core multiresolution techniques able to correctly project geometries onto the display and to dynamically adapt model resolution by taking into account the particular spatial accuracy characteristics of the display. The programmability of latest generation graphics architectures is exploited to achieve interactive performance. As a result, multiple freely moving naked-eye viewers can inspect and manipulate virtual 3D objects that appear to them floating at fixed physical locations. The approach provides rapid visual understanding of complex multi-gigabyte surface models and volumetric data sets.

Integral imaging, also known as Holoscopic imaging to be promising approach for glassless 3D and Its methodology uses the principle of “Fly’s eye” and hence allows natural viewing of objects (i.e. fatigue free viewing), In this paper, the main objective is to provide a new plug-in tools for full parallax computer generated 3D Holoscopic content, based mainly on 3D Virtual Reality Modeling Language parser to enable 3D integral images content and rendering to be produced from VRML file format, and displayed on auto-stereoscopic. In the proposed system, the 3D content is either captured by a single camera with a micro lens, cylindrical lens array or computer generated to allow for mixed 3D video generation. Multiprocessor ray tracing system is adapted to be able to generate 3D integral images that containing 3D IIVRML integral images content parser modules; new 3D IIVRML file format is created by uses 3D unidirectional camera parameters in order to import/accept into ray tracer rendere...
IEEE Transactions on Visualization and Computer Graphics - TVCG, 2009
The system described in this paper provides a real-time 3D visual experience by using an array of 64 video cameras and an integral photography display with 60 viewing directions. The live 3D scene in front of the camera array is reproduced by the full-color, full-parallax autostereoscopic display with interactive control of viewing parameters. The main technical challenge is fast and flexible conversion of the data from the 64 multicamera images to the integral photography format. Based on image-based rendering techniques, our conversion method first renders 60 novel images corresponding to the viewing directions of the display, and then arranges the rendered pixels to produce an integral photography image. For real-time processing on a single PC, all the conversion processes are implemented on a GPU with GPGPU techniques. The conversion method also allows a user to interactively control viewing parameters of the displayed image for reproducing the dynamic 3D scene with desirable parameters. This control is performed as a software process, without reconfiguring the hardware system, by changing the rendering parameters such as the convergence point of the rendering cameras and the interval between the viewpoints of the rendering cameras.
Natural 3D content on glasses-free light-field 3D cinema
Stereoscopic Displays and Applications XXIV, 2013
This paper presents a complete framework for capturing, processing and displaying the free viewpoint video on a large scale immersive light-field display. We present a combined hardware-software solution to visualize free viewpoint 3D video on a cinema-sized screen. The new glasses-free 3D projection technology can support larger audience than the existing autostereoscopic displays. We introduce and describe our new display system including optical and mechanical design considerations, the capturing system and render cluster for producing the 3D content, and the various software modules driving the system. The indigenous display is first of its kind, equipped with front-projection light-field HoloVizio technology, controlling up to 63 MP. It has all the advantages of previous light-field displays and in addition, allows a more flexible arrangement with a larger screen size, matching cinema or meeting room geometries, yet simpler to set-up. The software system makes it possible to show 3D applications in real-time, besides the natural content captured from dense camera arrangements as well as from sparse cameras covering a wider baseline. Our software system on the GPU accelerated render cluster, can also visualize pre-recorded Multi-view Video plus Depth (MVD4) videos on this light-field glasses-free cinema system, interpolating and extrapolating missing views.
Rendering for an interactive 360° light field display
ACM Transactions on Graphics, 2007
Figure 1: A 3D object shown on the display is photographed by two stereo cameras (seen in the middle image). The two stereo viewpoints sample the 360 • field of view around the display. The right pair is from a vertically-tracked camera position and the left pair is from an untracked position roughly horizontal to the center of the display. The stereo pairs are left-right reversed for cross-fused stereo viewing.
Prototyping a light field display involving direct observation of a video projector array
2011
Abstract We present a concept for a full-parallax light field display achieved by having users look directly into an array of video projectors. Each projector acts as one angularly-varying pixel, so the display's spatial resolution depends on the number of video projectors and the angular resolution depends on the pixel resolution of any one video projector.
