Introduction The ChemVis project is part of the strategic research initiative "V3D2" ("Distributed Processing and Exchange of Digital Documents") of the German Research Foundation (Deutsche Forschungsgemeinschaft DFG). The project is a collaboration between the Computer-Chemistry-Center (University of Erlangen-Nurenberg) and the Visualization and Interactive Systems Department (University of Stuttgart). The goal of the ChemVis project is the development of an Internet-standards orientated system for the embedding of dynamic and interactive high-end graphics in Internet-based chemical applications.The aim is to facilitate the understanding of complex factual relationships. For example, important chemical effects depend on 3D geometry, time scale and field effects and therefore are difficult to depict by a few static 2D images. The coupling and realtime manipulation of 3D visualizations, by user-initiated change of graph attributes, space/time parameters and other influencing factors facilitate a new quality and density of information. Such kind of information visualization is able to keep pace with the complexity of current research. Several examples shall highlight a range of uses and requirements of these dynamic scenarios. All applications described on this CD use platform-independent programming languages and data exchange formats like Java and VRML. The background management and retrieval of chemical information is handled by the open chemical data management system CACTVS [1].
