Abstract

A system is presented to visualize information about a city with a
three-dimensional Web user interface. We present a novel way to connect
a VRML world to an information database. As the data, code and models
are kept separate, updates and maintenance of the system is easy. The
information visualization of a city becomes easier and more intuitive in
3D. The location of any service, shop etc. is shown both in a 3D world
and on a 2D map, which are interconnected. Our implementation works on
standard Web browsers. In addition, we built an optional steering wheel
navigation, which is an intuitive way of moving around in a city for
home Internet users. An experimental immersive VR interface was also
made
