    A large scale interactive holographic display
    (IEEE, 2006) Agocs, Tibor; Balogh, Tibor; Forgacs, Tamas; Bettio, Fabio; Gobbetti, Enrico; Zanetti, Gianluigi
    Our work focuses on the development of interactive multi-user holographic displays that allow freely moving naked eye participants to share a three dimensional scene with fully continuous, observer independent, parallax. Our approach is based on a scalable design that exploits a specially arranged array of projectors and a holographic screen. The feasibility of such an approach has already been demonstrated with a working hardware and software 7.4M pixel prototype driven at 10-15Hz by two DVI streams. In this short contribution, we illustrate our progress, presenting a 50M pixel display prototype driven by a dedicated cluster hosting multiple consumer level graphic cards.

    A scalable holographic display for interactive graphics applications
    (2005) Balogh, Tibor; Forgacs, Tamas; Balet, Olivier; Bouvier, Eric; Bettio, Fabio; Gobbetti, Enrico; Zanetti, Gianluigi
    We present a scalable holographic system design targeting multi-user interactive computer graphics applications. The display device is based on back-projection technology and uses a specially arranged array of microdisplays and a holographic screen. The display is driven by DVI streams generated by multiple consumer level graphics boards and decoded in real-time by image processing units that feed the optical modules at high refresh rates. An OpenGL compliant library running on a client PC redefines the OpenGL behavior to multicast graphics commands to server PCs, where they are reinterpreted in order to implement holographic rendering. The feasibility of the approach is demonstrated with a working hardware and software 7.4M pixel prototype driven at 10-15Hz by two DVI streams.

    Collaborative immersive visualization without goggles -- experiences in developing a holographics display system for medical applications
    (2005-11) Bettio, Fabio; Frexia, Francesca; Gobbetti, Enrico; Pintore, Giovanni; Zanetti, Gianluigi; Balogh, Tibor; Forgacs, Tamas; Agocs, Tibor; Bouvier, Eric
    In this contribution, we report on the development of a novel holographic display technology that targets multiple freely moving naked eye viewers and of a collaborative medical application prototype that aims at exploiting this technology to provide medical specialists with a truly interactive 3D collaborative environment for diagnostic discussions and/or pre-operative planning.
