Among the numerous intuitions and projects that have characterized Leonardo da Vinci's art and technique, the conception of architectural structures has an important role, including studies and the proposal for the project of the tiburio of the Milan Cathedral. Based on some hypotheses of reconstruction of geometries and structural systems developed in the architectural field, and formulated as an interpretation of original drawings, it was intended to test whether the solutions proposed by Leonado were also actually feasible, examining them with current structural modeling techniques, of evaluation of static functioning and definition of structural safety. Using the finite element method (FEM), two different proposals were investigated for the vaults and supporting arches of the tiburio, finding its substantial reliability even though this was hypothesized in the absence of technical verification tools that did not exist at the time.

The research deals with the different image vectorialization techniques for the development of reliable drawings on mosaic systems. Following the restoration of the floor mosaics of the Basilica of the Nativity in Bethlehem, surveys were conducted with digital technologies that produced a 3D database on considerable mosaic surfaces. The problem of the graphic representation, linked to the drawing of these systems, concerns both the optimization of the methodological processes to the advantage of a more performing drawing activity, and the definition of the appropriate languages to satisfy requirements related to the documentation and the work restoration. Technical drawers have worked alongside restorers to produce technical drawings and a model from which interact with the mosaic system, developing an informative model that can facilitate construction activities and, at the same time, enhance the entire artwork.

This paper reports the preliminary results of an ongoing interdisciplinary research in digital humanities and animation that the authors are undertaking to explore how a new generation of three-dimensional (3D) non-photorealistic animated visualisations can improve upon two-dimensional (2D) visualisation methods. The outcomes of this research are enhancing both the studies and the user experience of digital representations of pictorial works that are seen as visual aggregators of human knowledge and experiences, because the sketching style and techniques of the artists are fully reproduced and made available to different interpretations. The mid-fifteenth-century atlas of the ships of the known world depicted in the Fra Mauro’s mappa mundi (Venice, Marciana National Library) has been used to: 1) showcase the design process and techniques of an innovative method through the prototyping of a 3D non-photorealistic-rendering (NPR) model of one ship, and 2) demonstrate the effectiveness of this method through the 3D NPR animation of all Fra Mauro’s ships as a contribution to both the advancement of learning in pre-modern maritime history (with a focus on shipping), and the implementation of NPR for the creative industry. These models are multiple purpose, because once they are created and implemented, the data can be displayed in different platforms (e.g., smart device, computer or larger flat screen, holographic pyramid, virtual reality, augmented reality, 3D printing).

The paper is going to discuss a methodological workflow, focused on the role of photoscanning-based immersive environments and three-dimensional models as tools for sharing, interpreting and elaborating diagnostic data for the assessment and control of the state of conservation of the architectural heritage. Specifically, from the identification of fields and aims, where the available tools and functionalities meet the support needs by the stakeholders, some experimental applications are developed with reference to two main aspects. The former concerns the creation of virtual tours of panoramic scenes, enriched by data from preliminary investigation, in order to enable the coordinated and integrated fruition of the pre-diagnosis qualification outcome. The latter relates to the employment of image treatment routines on coloured point clouds with the purpose of carrying out semi-automatic operations of decay monitoring for post-diagnosis control.

The use of advanced integrated survey techniques has allowed the acquisition of morphometric and colorimetric information to render three-dimensionally the frescoes by Francesco Solimena in the sacristy of san Paolo Maggiore in Naples. The research has explored different levels of knowledge by applying the necessary integration between consolidated knowledge and innovative technologies: combining innovative aspects of range-based modeling method and image-based modeling method, we created returnable models that can also be questioned remotely. The outcome is a contribution aimed at protection and enhancement of the cultural heritage, favoring conservation and restoration interventions as well as providing a permanent query of data and their complete use

As part of the restoration of the Neptune Fountain in Bologna, research was carried out, and certain design proposals were formulated which offer food for thought and give new light to the monumental complex within the context in which it is located, in the system of squares Maggiore and Neptune. The activity was divided into two distinct phases, the first was concerned with surveying the current state of lighting of the fountain and the adjacent spaces; the second focused on drafting proposals for a new lighting system, based on new LED technologies, of the fountain of Neptune and the areas immediately surrounding which was presented by means of synthetic images derived from the digital reconstruction of the site. This article presents the working method applied and the results achieved.

Non-destructive techniques are fundamental tools for a thorough knowledge of the construction aspects, structural conditions and pathologies of buildings. These tools become indispensable in the investigation of the Architectural Heritage subject to protection, guaranteeing the minimum invasiveness of the surveys in compliance with the architectural constraints. This paper presents the contribution that thermographer and thermofluometry have made in the knowledge and communication of the Former Hospital S. Salvatore in L’Aquila, Italy. The building, following the damage suffered by the 2009 earthquake, has been the subject of numerous studies but the analyzes presented in this work represent an element of novelty and a fundamental step for the upcoming restoration interventions

The contribution discusses the little-known topic of Italo-Argentine cultural heritage. The data gathered during the numerous studies performed so far have served as the basis for a Scientific Observatory. Its goal is to promote knowledge of the material and immaterial assets testifying to an integrated cultural process between the two countries as well as to highlight the relationship between Italian and Argentine culture during late twentieth-century mass immigration when Italians actively participated as designers, builders, entrepreneurs, businessmen, and teachers. All the data has been classified and is now being disseminated using a new archival and distribution medium: a visual, participatory experience present in public areas and the urban landscape.
