Digital acquisition and construction of three-dimensional

models of archaeological finds, environments and sites

of the Salento Peninsula.

It allows therefore the creation of several databases, as

for instance the 3D stelae and cippus database and

others, concerning in particular the archaeological

excavations of Cavallino (LE).

This example has been

discovered in the territory

of Cavallino (LE) in a heap

of stones dumped by

farmers near to a dolina at

the centre of a fenced zone

of archaic fortifications.





As the Director of the

Archaeological School of

the University of Lecce

specified, it is a fragment of

a stele (33x39x12cm)

rather badly preserved,

very splintered and with

large calcareous crusts

even on the figured area.

On the front side we

see a very low and

flat relief whereon we

can recognize two

horses attached to a

two-wheel vehicle

and a human shape,

in a primitive

representation, where

all elements are

taken to pieces and

spread over a single

plane.





This example (107x51x14

cm) has been discovered in

the ancient Messapian

settlement of “Muro

Tenente” in the province of

Brindisi. It is a stele on

which we can see a war

chariot and two rows of

hoplites with helmets and

long lances.





As specified by Prof.

D’Andria, we can find in this

stele, as in the one of

Cavallino, a reticulated

rectangular motif at the

lateral side, and, at the front

side, again we see a

representation in which all

elements are taken into

pieces and spread over a

single plane (this causes an

apparent overlapping of the

two rows of hoplites).

Of both examples two three-dimensional models have been produced, one with and one without texture.

To this purpose some digital photos have been used, produced with the digital photocamera Kodak Dc 265 of the Laboratory for the Digital Image Acquisition and Processing of the SIBA Coordination.

These photos, imported in Adobe Photoshop, have been calibrated, combined, resized and adapted to the model and afterwards they have been projected on it by means of Alias/Wavefront Studio.
