DeskTop Virtual Reality Application, accessible from Net environments
was initially created as a Desktop Virtual Reality application, so that
all users could access a part of virtually reconstructed Bologna from
the Internet. A light version of the application is available. It is
reduced and simplified so that it can be downloaded at normal speed
and viewed with a normal PC. A model that is richer in detail at a higher
resolution which is also available locally with Internet technology

(Virtual Reality Modeling Language) and Java , which was integrated
using External Authoring Interfaces (EAI), allowed for 3D modeling in
an urban environment and the management of the historical database.
At the same time it guarantees the development of portable, platform-independent,
standardized, interactive, dynamic 3D worlds.
historical period to visit can be chosen either through a text field,
in which the visitor types in the year, or a scrollbar which is comanded
by the mouse. Whenever the time navigation function is used, the entire
interface is updated. A button on the console shows (default) or hides
the 2D map of Bologna, which shows the visitors position as he moves through
the city. .
