Pompei oggi. La rappresentazione del sistema complesso nel progetto di conoscenza, fruizione e rigenerazione dei beni culturali

This study aims at exploring, through architectural and environmental representation and survey, the n dimensions that define images and spaces in new urban contexts, whose changes are often the result of chaotic accumulations generally due to processes of addition or superimposition of signs of contamination on those of permanence. The outcome is a high and widespread environmental disorder with consequent and generalized inconveniences on both functional and perceptual levels. Our research is focused on the analysis of material and immaterial dimensions configuring the urban environment as the product of an historical substructure projected towards future and featuring characteristics that undergo rapid changes. Thanks to a method offering an open tool of inquiry intending to assess the degree of acceptability of contemporary changes, the research was developed by decomposing the space of the realities surveyed into different scales of representation through the selection of layers. Each layer is able to recognize categories and problems concerning form, use and function of urban contexts. The second aim of this paper is to study the ornamental geometrical drawings of the Roman mosaic floors in Pompeii. The research explores the following topics: the cataloguing of the geometric mosaic floors in Pompeii; the analysis of the geometric shape of the catalogued ornamental drawings; digital modelling and animation of the ornamental geometric drawings; the design of a digital game; the implementation of a GIS database on a basic LIDAR system. The data collected about the geometric designs of the Roman mosaic floors and the results of the geometrical analysis were organized into a GIS database. Through the digital interface, it is possible to access an application that enables users to design new geometric patterns based on the symmetries and the colours of the Roman mosaic floors analysed in the study. This application also includes a digital game which could be used to improve our knowledge of the archaeological area of Pompeii.
