More specifically, the tour has been improved by adding data: 
other panorama and pictures taken at different seasons, other 2D 
data, text and explanations, etc. It also gives the possibility to 
generate the virtual tour and to access to the website on an iPad 
or other mobile device. Guides of the archaeological site could 
then use this application as a real source of information while 
showing the site. The tour would then become more interactive. 
A problem remains: to be able to update information regularly 
and to add features to the tour, a process must be created to 
optimize the generation of the tour. It would then be possible to 
add fresh news or temporary data very easily. 
As far as the 3D model is concerned, the integration of 
archaeological models and theories would bring a special 
interest. However the idea of an automated process to update the 
data from the 3D model into the virtual tour is still an unsolved 
problem.
