often uncertain data (Strothotte 1999). For eaxmple when doing
a reconstruction of an ancient site to show how it was in it’s
prime, then some go as far as proposing to use non-
photorealistic rendering of the 3D models to highlight the fact
that what we are showing is an interpretation of how the site
might have been and not necessarily a truth to be taken for
granted.
The virtual environment could be used to compare two different
reconstructions of the same object. By rendering both objects
in semi-transparent mode the differences could easily be
distinguished. All sorts of interactive tools for archaeologists
are possible. The whole process of reconstruction of the missing
pieces could be done in virtual mode and then recorded. Finally,
the video could be enriched with narrative that describes the
whole process and serves as a documentary. Integration with
haptics devices is another interesting area. The user would be
able to feel the shape of the object and the whole experience
becomes more believable (Bergamasco et al, 2002).
5. DISCUSSION-CONCLUSIONS
The paper presents a complete process of converting an
archaeological object (i.e. a tomb) to digital representation and
exploration of that site in a virtual environment. Starting from
scratch the spatial information is collected using
photogrammetric techniques. At the following reconstruction
techniques applied to create the 3D object model and then
visualization and animation techniques to illustrate a true
representation of the up to date situation.
