    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.
