Virtual Reality
models of building
VR models of buildings can be
used for several purposes; document management, interior design option
analyses by end users, operations planning, evacuation simulations etc.
Construction practitioners expect rather widely that vr model can be the
user interface to complex data and models in near future. For example by
pointing a particular object in the building model the user can obtain
all documentation relevant to that object. This feature means that in
the nearby future the instructions for service and use can take full
advantage of virtual reality technology
The generation of a vr model from
normal project engineering and design data is possible with some current
software packages. Another method is to use a special software to create
vr models. These methods have couple of drawbacks;
- Exported vr models from the
engineering data are often based on a specific data format => in
order to use these models the user needs to have a special software
depended browser
- The creation a vr model from
scratch requires a lot of work
To avoid extra work in creating
the model and to offer a generic approach for browsing the users of vr
models should be able to export the engineering and design data to a
multipurpose file type. A specific tool, ProMoTe,
developed in VTT Building Technology creates a VRML file from IFC
product data model.
Most of the existing buildings
have been constructed in a time when the drawings were prepared manually.
Thus in order to have a vr model of any building of this type it is
necessary to measure the dimensions of the building and convert this
information to 3D model. Various methods for achieving a vr model from
existing buildings are described in the next slide show:
