Powerful servers for computation and storage, high-speed networking resources, and high-performance 3D graphics workstation, 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 inefficient… (More)
The paper describes the development of a high-performance system for visualizing complex scientific models in real-time. The architecure of the system is a client/server model, in which the simulator generates lists of 3D graphics objects in parallel to the simulation, from where they are sent to a streaming server. The server transfers the 3D objects to… (More)
Online presentation of virtual 3D objects in the Web, based on Internet standards, is limited due to several performance bottlenecks, quality restrictions and missing func-tionality. Particularly in the scientific context, where high-performance client, server, and network equipment exists, and requirements for high complexity of represented 3D geometry are… (More)
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… (More)
Currently available massively parallel supercomputers provide sufficient performance to simulate multi-dimensional, multi-variable problems in high resolution. However, the visualization of the large amounts of result data cannot be handled by traditional methods, where postprocessing modules are usually coupled to the raw data source – either by files or… (More)
This paper describes the concept for an electronic magazine (EZine) based on the World Wide Web. The project aims at creating an electronic magazine as the online version of an already existing printed scientific magazine, which will primarily supply the content. The articles in this EZine contain various types of media, including text, images, audio, video… (More)
Der klassische Ansatz, Ergebnisdaten zu speichern und die grafische Aufbereitung (Post-processing) anschließend auf speziellen Visualisierungsrechnern durchzuführen, verbietet sich für bestimmte Grand-Challenge-Anwendungen (z.
In this paper we present a software whiteboard for multimedia conferences. The whiteboard is specialised to load and share high-resolution colour images while using colour management functions to provide an accurate colour representation. The whiteboard is used in the tele-medicine project INTERFACE , which builds a virtual environment for… (More)
