context an on-line modeler would be very beneficial. During 
point measurements the results of this modeler could be 
injected into the stereomodel at any time and the operator could 
control the agreement of the on-line model with the 
measurements and the structure of the object. In our case we 
had to intervene manually into the surface modeling process 
more than we had expected originally. 
Currently the fundraising efforts are underway to support the 
physical reconstruction of the Great Buddha of Bamiyan.

ACKNOWLEDGEMENT 
The authors would like to thank all the people who take part in 
this project and in particular: Prof. Kostka, Technical 
University of Graz, for the three metric images; Vexcel, for 
scanning the metric images; B. Weber, Founder of the 
New7 Wonders society; P.Bucherer, Director of the Afghanistan 
Museum in Bubendorf, Switzerland; Robert Zanini and Joachim 
Wirth, Institute of Virtual Manufacturing, ETH Zurich, for the 
physical reconstruction of the statue at scale 1:200; Tom 
Bilson, Courtauld Institute of Art, London, for some Internet 
images of the Bamiyan statues; all the web sites where we 
found images of the statues; Yuguang Li for the manual 
measurements on the metric images.
