Supporting dynamic information visualization with VRML and databases

Nowadays, many state-of-the-art user interfaces to complexly structured data collections require appropriate information visualization methods. With the increase in graphics performance available on client systems, methods for three-dimensional visualization can be applied more easily. The conceptual approach presented in this paper dynamically generates threedimensional VRML scenes from information stored in database systems. To achieve this, VRML is extended with new nodes for supporting the server side generation of VRML scenes and for supporting trigger mechanisms. An implementation of the introduced concept is introduced by means of an object relational database system which is extended with a new VRML data type and its related functions. Altogether, these concepts and software components provide a platform for server-based information visualization mechanisms.
