alignments for columns, their quantification and the
analysis of crashes and structural failures in the global
3D model.
The western facade shows an evident list, which is
responsible for two large crashes across the wall, from
roof to ground. In the eastern end of the temple, there
appear severe crashes along windows which threaten
the stability of its structure. Inside, the vaults are apparently
full of cracks and a considerable number of ashlar
blocks have fallen from the arches.
Crashes are also evident on the other end of the central
nave, where lateral walls are literally detached from
the roof. A large number of fractures also appear in the
startings of arch nerves with the walls.
Data Capture and Global Model
In order to ensure a common general reference for the
model, the scans are registered to a network of control
points both in the exterior and interior of the church. Up
