A VR model is the future user interface to all complex data. Used
in construction, the user can simply point to a particular object
in the building model to obtain all documentation relevant to that
Building VR Building Models
The generation of a VR model from normal project engineering and
design data is possible with some current software packages. Alternatively,
special VR modeling software can be used. Models built on separate
software are often based on a specific data format and require a
small plug-in the be uploaded to the viewers browser before they
can view the model.
To assist in expoerting engineering and design data to a multipurpose
file type, specific tools have been developed, for instance, ProMoTe,
developed in VTT Building Technology creates a VRML file from IFC
product data model.
In simple terms a VR model is built by converting the dimensions
of the building to 3D model, and from there, VR models. This is
just one simple step forward to standard 3D capable AutoCAD programs.

Viewing 3D and VR Models
In most cases viewing and interacting with 3D and VR-models requires
only a capable computer and an appropriate freeware VR-model viewer.
To collaborate on the design, full exploitation and utilization
of all features is required, necessitating special presentation
technology, such as:
CAVE is a room in which the user can feel immersion and interaction
with the vr-models. A cave has either one curved wall (ConCave)
for displaying 3D/4D models or one to six walls (non-curved) for
the same purpose. Responsive workbench is a 3D interactive workspace
originally developed in Germany. Responsive workbench has been used
e.g. to study alternative schedules (Stanford
