In this paper we introduce Virgilio, a system which generates VR-based visualizations of complex data objects representing the result of a query. Virgilio takes as input the dataset resulting from a query on a generic database and creates a corresponding visual representation composed of a collection of VRML (VR Modeling Language) scenes. The system uses a repository of real world objects (e.g., rooms, tables, portrait cases) which includes their visual aspect, the types of data they can support as well as a containment relationship among pairs of objects. Virgilio works in the following way: (i) attribute values of the dataset are displayed on virtual world objects according to the capability of these objects to represent the proper type of data, (ii) semantic relationships among the objects in the dataset are represented using the containment relationship.The main features of Virgilio are: to be parametric with respect to the explored database, to automatically produce an user oriented view of the dataset and to describe visualized data by means of the VRML language.A system prototype is currently being implemented. As an example, we provide a set of snapshots showing the scenes built by Virgilio to represent the result of queries defined on a database of musical CD records.
