FIG.2 - THE ASCENSIONE'S DOME IN THE ST. MARCUS’ BASILICA. 
THREE-DIMENSIONAL ELABORATION OF THE PHOTOGRAMMETRIC 
RESTITUTION: THE DIGITAL MODEL HAS BEEN TREATED WITH SOLID 
MODELLING AND SMOOTHING OF THE ELEMENTARY SURFACES. 
  
FIG.3 - PROJECTION OF THE DIGITAL IMAGE OF THE SPIRITO 
SANTO’S DOME ON A SPHERE WITH MAPPING PROCESS. THIS IS NOT 
OBTAINED WITH A RIGOROUSLY ANALYITICAL SOFTWARE BUT WITH A 
SIMPLY QUALITATIVE ONE. 
INFACT THERE ISN’T STILL ANY ALGORITHM AND THE ALGORITHMS 
ARE THE FINAL POINT OF THE RESEARCH JUST BEGINNED. 
THE PROBLEM OF THE IMAGE DEFORMATION ON PLAINS AND SURFACES 
HAS BEEN REDUCED, WITHOUT CONSIDERING THE ANALYTIC ASPECT, 
TO THE PROJECTION OF ANY IMAGE ON ANY GEOMETRICAL SHAPE. 
IT IS SOMETHING LIKE AN IMAGE REFLECTED ON A SOLID. THIS IS 
THE PROBLEM TO BE SOLVED.
