There are a few firms who specifically work on providing a service in construction
and realtime 3D visualization of cities. If you know of others, please
let us know.
Their in-house proprietary software is called FastBuilder. It
does "automatic modeling of complex territories from heterogeneous spatial
data". They have been developing FastBuilder for more than 7 years.
It is especially designed to generate 3D models automatically from IGN data
(the French National Geographic Institute).
The models can be viewer in a webpage using Shockwave, or as a stand-alone
application (built on OSG/Qt).
Their showcase models are Paris and Rennes, as describe on the
Virtual France page
Typical fields of use inlude 'landscape, town planning, architecture,
infrastructure'
Their partners are entirely French.
There is a private site in English with downloadable applications demonstrating
their city content. http://demo.archivideo.com user=vtp

Services available to municipalities for "creating, managing and using
digital 3D city models"
Services include 3D laser scanning (mobile mapping), organization of
aerial photos, processing of roofscapes, façades and street plan, underground
installations and tunnels, structural engineering and excavation projects
They use a suite of in-house software (CityGRID Modeler, Manager, Planner, Explorer, Scanner, Ortho) which interoperates
with ESRI products for a GIS connection
CityGRID Explorer is the VRML-based interactive 3D module (not freely
distributed)
Builds "PC-based high-resolution urban simulation VR models for a wide
variety of architecture and planning applications" with their own proprietary
run-time, SimView
They have done a number of projects in the state of Michigan, USA, where
they are located
Offers a rapid city modelling service, at a typical cost of $150k per
km2
"A full spectrum of core capabilities and custom solutions for urban
infrastructure, tourism and travel, real estate, security and defense, 3D
yellow pages, entertainment, media and advertising applications"
One of the very first companies to focus on 3D urban modelling in the
1990s, they have helped coordinate the development of many "virtual cities"
in 3D Studio MAX and VRML
Most of them use a single very low resolution ground texture combined
with simple extruded building outlines for a small number of downtown buildings
Cities include: Atlanta, Austin, Baltimore, Boston, Chicago, Denver,
Lake Tahoe, Las Vegas, London, New Orleans, New York, Portland, San Diego,
Sydney, Tokyo, Vancouver
Partnered with 3D Geo, they use
3D Geo's LandXplorer software suite to provide city-modelling services,
and to deliver solutions based on those models
They are 'the recognized system integration partner for LandXplorer
products.'
Examples of cities they have modelled in Germany (Berlin, Chemnitz,
Dresden, Leipzig) and Akron, Ohio in the USA, a highway in Italy, and
several other urban planning and transportation projects
