For example the column definition happens corresponding on
two oriented images 4 points on the column, as reported in
figure 5.
The “marking curves” command has permitted the modelling of
the capitals and the column basement; in this case the operation
starts from a 3D known point, then, following the object
morphologie, are defined many curve nodes.
Unfortunately, if the column modelling has came to a very good
result, the modelled capital is quite different the real one (figure
6).
