Austin by Planet 9 Studios illustrates the sue fo VRML to represent urban form. Plannet 9 is the biggest proucer of 'virtual cities' on the WWW and all thier models follow the same form. VRML is used to create the urban layout and textures are used to add detail.

Boston by Planet 9 Studios - details as above

Bath produced by CASA at Bath University, funded by a grant J. Sainsbury plc to construct a three- dimensional computer model of Bath. The project was supported by Bath City Council and since its completion the model has been used by the city planners to test the visual impact of a number of proposed developments on the city. This is good example of the use of VRML to produce virtual models of cities.

Helsinki Helsinki Telephone Company project has initiate Helsinki Arena 2000- consortium project in collaboration with the City of Helsinki. The project aims to develop a Virtual Helsinki intothe Cyberspace and the project has received a widespread support of business and public organisations. The project will culminate in the year 2000, a festive year for the City of Helsinki. The Current VRML model (662k) makes good use of viewpoints to create a virtual tour.

Las Vegas by Planet 9 Studios

Ottawa by Wizard Solutions The VRML model includes good use fo viewpoints and embedded URL links to WWW pages. The VRML 2.0 version also features a 3D sound source and tour based viewpoints. Although no social aspect is included in the model, the use of embedded information and moving tour viewpoints illustrates a good represention of a basic virtual city.

Siena by Construct makes good use of basic textures to create the atmosphere of an Italian City. Contruct have made imaginative use of hyperlinks and level of detail to create one of the few representaions of urban form which creates a true sence of place.

Tubingen the primilry result of the The Virtual Tübingen Project- Applying virtual reality technology to psychophysics at the Max Planck Institut. The model uses VRML based on basic input data consist of architectural drawings provided by the city administration. The project is develping techniques to simulate the urban form in VRML.

Toronto by Wizard Solutions, simliar in development to the Ottawa model by Wizard solutions, good use of Viewpoints and embedded URL links to homepages.

Warsaw by M. Jacek Szamrej University of Warsaw, one of the virst represntations of urban form on the WWW. The model is basic, but is a good illustration of how streets can be modelled using VRML.
