Title
New perspectives to save cultural heritage
Author
Altan, M. Orhan

CI PA 2003 XIX 11 ' International Symposium, 30 September-04 October, 2003, Antalya, Turkey
Natural and artificial illuminances on the internal surfaces are
measured. Results are presented on the plans. An example is
given in Figure 3 [9].
External daylight illumination levels depending on the average
sky conditions and statistical meteorological data of the region
were used to obtain realistic internal visual virtualisation.
Luminaire location plans are determined in situ and luminaire
light specifications are measured in laboratory [9]. Data on the
inner surfaces colour and light reflectance properties are
measured in situ by using high quality colorimeter [10].
5. CONCLUSION
The main objectives of the CAHRISMA research project are the
identification, revival and conservation of architectural heritage
from a new perspective. Objective and subjective evaluations
and audio-visual reconstruction of Sinan’s Mosques and
Byzantine Churches in real-time 3D virtual environments are
the basic approaches of the project. Virtual restoration, virtual
conservation, and the determination of different significant
acoustical effects are to be the main results. By means of this
wide frame research, conceptual and practical innovations will
be created in the fields of acoustics, architecture and simulation
technologies.
On the other hand, selected worship spaces are undoubtedly the
best examples of their type and their era. The conservation of
those religious edifices in a virtual environment will be a great
step and a perfect example to the innovation of conservation
and restitution methods.
In the virtualisation, one or several of the topics presented in the
text may have a special importance depending on the function
of the building; therefore the data collection should be
rearranged according to the building function.
