The software used tor the operations of straighten is the Rollei MSR. The final result has satisfied completely the expectations, 
bringing to light many frescos that aren t in general clear visible to the usual visitor because the low illumination. 
3.2 Curved Surfaces 
For the surfaces of the niches, of the plumes and the dome is been instead applied the stereoscopy. That has foreseen the use of a 
special CDW software of the Rollei that has allowed, beginning from the photographic images and from a series of points of support, 
to reconstruct the camera orientation at the moment of release, during a photogrammetric bundle adjustment.The result of this 
operation wasn t as for the plain surfaces a straightened image, but numerical informations used in the following phase of mapping. 
4. 3D MODELLING 
After have created the model through the AUTOCAD software and have gotten the results of the photogrammetric elaboration, these 
informations were inputed in a software that can allow to integrate them, in order to respect the precisions required as work objective 
and to obtaine the valuable results also from the point of view of the quality of the graphic restitution. For this purpose has 
considered as the ideal tool the software 3D STUDIO MAX. 
4.1 Surfaces Mapping 
The phase of mapping of the images upon the 3D model, created on the base of the geometries measured during the topographical 
survey, was completely realized through the software 3D STUDIO MAX. 
The methods used were different according to the surface that were to be mapping. Particularly a different procedure was used for the 
dome which has required a specific study. On the base of the photographic cover and in order of the semispheric geometry, was 
considered reasonable, also according with the precisions to obtain, to divide the calotte surface into 12 segments. With the 
informations obtained through the application of the CDW software, each single segment was mapping, verifying for each ones the 
congruence in the position of the numerous painted stars, that define the meridians of the dome. The gotten results have been 
satisfying and consistent with the objectives imposed. 
An analogous procedure was used for the niches and the plumes: in fact it has been sufficient use the 3D model as a screen and 
project the corresponding image using raytracing techniques. The ’’Digital Projectors” use the same interior and exterior orientation 
as related cameras, obtained from bundle adjustment. This has been possible thanks also to the potentialities offered from the 
software 3D STUDIO that has allowed to set the parameters in a correct way. An other big advantage of this software is the complete 
compatibility with the AUTOCAD software, used for the reconstruction of the geometric model. 
Simpler was instead resulted the mapping of the images previously elaborated through the MSR software, for which has been 
sufficient to project directly the image upon the corresponding surface through a plane parallel to the same surface. The image gotten 
at the end of straighten and merge phases is in fact an orthogonal projection of the photographed surface.
