The 3D model (PID or PlanetaryInteractiveDiorama) of the city of Turin
3.0 is under development by Ultramundum Foundation.
This model is derived from 2.0 and 1.0 versions, already completed, and
will deliver the entire city for free interactive exploration on a standard personal
computer, with an extremely high level of realism and realistic personal / veicular
The model is completely open source and its Tabulae (elements at the
base of the technology used) will be freely accessible and modifiable by everybody.
Until today, only portions of a city have been modeled with similar
technologies, because the data load for a model such this, with hundreds of thousands of
buildings, has ever been prohibitive. The Turin 3D model allows for interactive
exploration on a standard personal computer with a modern video card. Out-of-ordinary
powerful computers are not necessary.
Thanks to patented UltraPeg technology, this model offers an interactive
flight on all the city with the possibility of descent to the ground level of any single
street to walk amont he buildings. Getting altitude the speed increases accordingly to
allow for an exploration experience easy and really natural.
Every building of the city is present, with highly realistic graphical
details. Flowerbeds, as it is visible from the first images of the prototype, have details
of the grass and not a simple green surface. A powerful automatic traffic generation
system, already available as an academic research, will be inserted into the
cellular-subdivided city structure. Veichles and people will walk around the streets and
boardwalks to bring to life the entire city.
Any Tabula, the data structure at the root of Ultramundum Foundation's
UltraPeg technology, can hold multiple data types. For the Turin city model, informations
on buildings positions, root maps, olympic areas placements and specific schematics have
been imported from Autocad files and other databases.
The Autocad file importer, called UltraTools, allows for fast and almost
automatic acquisition of public databases, converted in a very short time to
three-dimensional elements. All these data can then be explored in real-time.
The Foundation can arrange interactive demonstrations on request,
because this product can not be freely distributed yet.
