Virtual reality movies-real-time streaming of 3D objects

Powerful servers for computation and storage, high-speed networking resources, and high-performance 3D graphics workstations, which are typically available in scientific research environments, potentially allow the development and productive application of advanced distributed high-quality multimedia concepts. Several bottlenecks, often caused by the inefficient design and software implementation of current systems, prevent utilization of the offered performance of existing hardware and networking resources. We present a system architecture, which supports streamed online presentation of series of 3D objects. In the case of expensive simulations on a supercomputer, results are increasingly represented as 3D geometry to support immersive exploration, presentation, and collaboration techniques. Accurate representation and high-quality display are fundamental requirements to avoid misinterpretation of the data. Our system consists of the following parts: a preprocessor to create a special 3D representation - optimized under transmission and streamed presentation issues in a high-performance working environment, an efficiently implemented streaming server, and a client. The client was implemented as a web browser plugin, integrating a viewer with high-quality virtual reality presentation (stereoscopic displays), interaction (tracking devices), and hyperlinking capabilities.
