In the specific case given as an example, solid constructed

Texture mapping 
The need today is to place more and more attention on the 
quality of the photography since the demand for high quality 
photographic results has grown steadily, starting with analogical 
and digital rectification to photoplanes, orthophotos, and texture 
mapping on 3D models. These products have become a 
substantial part of the photogrammetric production that serve as 
support for the historic, physical and chemical analyses which 
are usually done on the monuments. You can see how initially 
(for example, in analogical rectification) photography mainly 
served to measure sheet coordinates (surveyors often rectified 
from negatives). Since rectification began to develop, not only 
in vectorial form (line drawing) but also in photographic form, 
the need arose to have images where a certain degree of colour 
fidelity, in addition to the metric reliability, could be ensured. 
Today, we are experiencing the need to acquire calibrated 
colours that become a specific theme analysis for the 
monument: colour must be able to be verified in space as well 
as time. 
On the model of Scarpa's architectures that we surveyed, digital 
images calibrated radiometrically are used as textures to obtain 
a colour map. 
3D models with mapped surfaces are surely the most versatile 
representation: mappings can be not only simple integrations of

the geometric model but they may be the result of specific 
analyses. 
The opportunity offered by the geometric 3D models that 
warrants extensive further investigation and the peculiar 
characteristics of Scarpa’s architetture lead to evaluate the 
possibility to realise multiscale models, that can be used on 
various nominal scales of representation considering not only 
the entire building but even each plastic detail. 
  
In addition to the static images, it is also possible to use the 
3DSMax animation module to create highly useful videos. 
While the advantage of this type of animation, as for rendering, 
is the complete autonomy in the machine movements, its limit 
lies in the fact that it is a representation impenetrable by any 
interaction in real time.
