ABSTRACT
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 three-
dimensional 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
