This study focuses on the analysis of the several transformations which are observable in a particular area of the inner city of Rome, and furthermore aims to provide a working method that could be increased and widened, in order to be applied to further individual cases. The first step of the work consisted in leading an historical research, by means of bibliographical, cartographic and iconographic sources, which were essential to first draft a diachronic summary of all the permutations concerning the area, and to indentify the main temporal sections. The documents collected were subsequently arranged and interpreted, to serve as a basis for the final composition, in which the many pieces of information were then compared. The applicative and experimental phase was structured over two different scales of representation: a urban one and an architectonical one. A first series of processed images was meant to retrace the transformations suffered by the building pattern from the 16th century on. A deeper analysis focus on the essentially architectural aspect, and brought to the processing of further models at a more detailed scale. At last, the research is centred on a very narrow area: the Ripetta Harbour, a point of particular convergence for the whole economical and social life of the neighbourhood: the outcome consists in a sequence of 3D reconstructions, aimed to covey a visualization, as clear as it can be, of the changes that followed one another, both on an overall urban scale of the area itself, and on a more detailed level concerning the bordering buildings, which can be useful to whomever aims to develop further studies to be founded on this one.

This study is an opportunity to test the effectiveness of a method of critica reading for the redevelopment of the urban image. There are areas, which by their own nature display features of indeterminacy such as to require measures of intervention to enhance the resolution of flaws in the design. Among them we count those places, which, built during the development of the urban centers, show clearly the transition between the existing cores and the subsequent expansions. There are areas that represent, on a single level, the projection of the stratification of different constructing realities; others that, because of the undefinedness of this process, express in themselves strong spatial tensions. An example of this is the area aside the town of Monterotondo, which is configured as a single space on the edge of the old center and that has been consolidated over time becoming one of the main axes of the town. In this direction, we suggested a cognitive method characterized by three subsequent but interrelated stages of processing: - A "cognitive moment," consisting of the acquisition of metric data and its restitution. - A "evaluation moment", implying that processing critique of "cognitive moment" that directs and limits the range project choices. This moment, link between the objective assessment and the critical planning, represents a moment of synthesis, capable of expressing the level of knowledge acquired of a place by an inspecting subject. The easy access to the totality of information is essential for the conservation of it, as for the spreading of any cultural resource. - A "proactive moment", which aiming to the formalization of guidances for the transformation of the reality itself, is the final conclusion of the whole methodological process. The fundamental target of the research was to get to an objective representation of the city or of part of it, trying to convey the result of the critical analysis in a clear and readable modality. The final result is the production of various 3D urban models, that are used to support all the possible measures in order to monitor and redevelop the city itself. The Attention has been focused on the development of analysis and consultation systems that enable the diffusion and sharing of digital representations of the city, either in the scientific and professional environment, or among the general public.

Viene condotta una valutazione critica relativa all'introduzione sperimentale della Realtà Aumentata in ambiti di natura architettonica e di rappresentazione multimediale interattiva ad essi relativi. Lo studio condotto concerne lo sviluppo di applicazioni su piattaforme di Realtà Aumentata, finalizzate a ricostruzioni virtuali di beni architettonici.
