FIG.4 - SPIRITO SANTO'S DOME IN THE ST.MARCUS' BASILICA. THE 
BEGINNING OF THE RESEARCH: THE IMAGE OF THE DOME IS 
PROJECTED ON ITS OWN SEMISPHERIC 3D SURFACE. THE RESULT IS 
PRINTED ON LASER POSCRIPT. 
LIKE EXPLAINED IN THE PAPER IT’S NOT REALIZED YET A 
PROJECTIVE HOMOLOGY BETWEEN ONE POINT ON THE IMAGE AND ITS 
| CORRESPONDING ON THE 3D MODEL (LOWER PART OF THE PICTURE). 
  
THE MOSAICS ARE PROJECTED ON THE INTRADOS OF THE DOME. THE 
SURFACE HAS BEEN OPACIFIED ON THE EXTRADOS IN ORDER TO 
OBSCURE THE MOSAICS NOT VISIBLE. 
THE PRINCIPLE OF THIS PROCESS IS TO MEMORIZE A GREAT NUMBER 
OF PHOTOS AND IMAGES AND TO PROJECT THEM ON THEIR OWN 
SURFACES: IN THE WAY TO VISUALIZE THEMSELVES ON THE 
DIFFERENT POINTS OF VIEW SELECTED TIME BY TIME (UPPER PART 
OF THE PICTURE).
