A tele-immersive, virtual laboratory approach based on real-time streaming of 3D scene sequences

In this paper we describe a distributed system approach for three-dimensional exploration in the context of high-performance com¿puting, which supports postprocessing, online-visualization and in¿teractive steering scenarios. Our processing chain consists of three instances (data source, streaming server, viewer), which can be dis¿tributed in high-performance networks and operated either in a full pipeline (on-the-fly 3D visualization, computational steering) or in asynchronously running pairs (visualization of prepared 3D scenes). It takes advantage of parallel data extraction, efficient 3D representation, and streaming protocols over TCP/IP.
