Editorial for the Special Issue: “3D Virtual Reconstruction for Cultural Heritage”
Full text linkThe use of 3D modelling, computer-aided design (CAD), augmented reality (AR) and virtual reality (VR) for the acquisition and virtual reconstruction of Cultural Heritage is of great importance in the analysis, study, documentation and dissemination of the past. Reverse engineering (RE) and computer graphics (CG) are also relevant aids for the visualisation and preservation of Cultural Heritage. The integrated use of AR and VR technologies helps to accomplish the full potential of 3D models obtained with reality-based techniques and CAD data, and it aims at interactively communicating the significance of the heritage to non-experts. AR and VR are valid tools for interacting with 3D models and help make culture more accessible to the wider public. Their flexibility can help museum curators to adapt cultural proposals and information about artefacts based on different types of visitor’s categories. These technologies allow visitors to travel through space and time, have fun and get educated on complicated topics. VR/AR technologies are also extremely useful for recreating a lost or hidden environment, leading to a better comprehension of the site or allowing people to discover important sites that are not visible, both for security and conservation reasons
Resilient Connections
Full text linkThe paper presents Axis Strutture awarded with V:alere funds (VAnvitelli pER la ricErca 2020) for the establishment of an innovative start-up, now academic spin-off. It is based on the assemble of iron and wood with 'pins' (in Latin 'axis') threaded to ensure an economic profit in line with the Sustainable Development Goals, reviewing ancient technologies in the light of advanced research. The focus is on the structural connections of a construction system that clamps the steel frame elements with the wooden infill, allowing to assemble modular, prefabricated and flexible components customized on the design phase’s request. It provides effective emergency shelters assembled or dismantled as quickly as tents but more stable, healthier and comfortable. With a single star key, the steel uprights can be attested with wooden and similar tampons avoiding nails and screws which allows the total reuse of the components. The patented connections implement a new construction method promoting the self-construction of garden houses, leisure environments, bungalows, garages and quality housing modules, since they are resilient, resistant and with a controllable impact on the environment. The case study provides an opportunity to verify actions aimed at the implementation of Design for Adaptability strategies promoting virtuous life cycles that involves the entire community in sustainable models from an economic, environmental and social point of view

No full textThis paper explores the possibility of counteracting the crisis of culture and institutions by investing in the identity values of the user-actor within digital spaces built for the purpose. The strategy is applied to the analysis of three Catalan cloisters (Spain), with a focus on the representation of the cloister of Sant Cugat (Barcelona). Heuristic picklocks are found in the semantic richness proposed by Marius Schneider exclusively on the verbal level. The authors interpret the contents and transcribe them into graphic signs and digital denotations of sounds and colors. They organize proprietary ontologies, or syntagmatic lines, to be entrusted to the management of computer algorithms. The syncretic culture that characterized the medieval era allowed the ability to mediate science and faith to be entrusted to the mind of the praying monk alone in every canonical hour. The hypothesis that a careful direction has programmed the ways in which to orient souls to “navigate by sight” urges the authors to find the criteria that advanced statistics imitates to make automatic data processing “Intelligent”. In step with the times and in line with the most recent directions for the Safeguarding of Heritage, the musical, astral, and narrative rhythms feared by Schneider are used to inform representative models, to increase not only the visual perception of the user (XR Extended Reality) but also to solicit new analogies and illuminating associations. The results return a vision of the culture of the time suitable for shortening the distances between present and past, attracting the visitor and, with him, the resources necessary to protect and enhance the spaces of the Romanesque era. The methodology goes beyond the contingent aspect by encouraging the ‘remediation’ of contents with the help of machine learning
The slab of Perugia: graphic virtualization for the enhancement of cultural heritage
No full textThe article proposes a reflection on the architectural contents of the iconographies carved on a marble slab called slab of Perugia of the second half of the first century, kept in the archaeological museum of the Umbrian capital. The measurements expressed in fractions of anthropometric units in force at the time certify the legal nature of the document. The authors, moving from the graphic interpretation of the find to the design control of the three-dimensional reconstruction, take the opportunity to reflect on the opportunity to share VR and AR collaborative platforms, useful for promoting scientific knowledge in relation with the current civil commitment and to the economic development
3D Reality-Based Survey and Retopology for Structural Analysis of Cultural Heritage
No full textCultural heritage’s structural changes and damages can influence the mechanical behaviour of artefacts and buildings. The use of finite element methods (FEM) for mechanical analysis is largely
used in modelling stress behaviour. The workflow involves the use of CAD 3D models and the use of non-uniform rational B-spline (NURBS) surfaces. For cultural heritage objects, altered by the time elapsed since their creation, the representation created with the CAD model may introduce
an extreme level of approximation, leading to wrong simulation results. The focus of this work is to present an alternative method intending to generate the most accurate 3D representation of a real artefact from highly accurate 3D reality-based models, simplifying the original models to make
them suitable for finite element analysis (FEA) software. The approach proposed, and tested onthree different case studies, was based on the intelligent use of retopology procedures to create a
simplified model to be converted to a mathematical one made by NURBS surfaces, which is also suitable for being processed by volumetric meshes typically embedded in standard FEM packages.
This allowed us to obtain FEA results that were closer to the actual mechanical behaviour of the analysed heritage asset
Virtual navigation in the ancient Egyptian funerary rituals
No full textThis paper shows a VR application for explaining the meaning of the various pictograms and hieroglyphs typical of the ancient Egypt funerary rituals. The interaction between the user and the 3D environment is obtained through an Oculus Rift head mounted stereoscopic display, coupled with a Leap Motion controller as input device that digitize in real-time the hands of the end-user, displaying a skeletal version of those in the virtual environment. The interactive application is based on Unity3D and it explains the details of the rituals starting from the crate of an Egyptian sarcophagus and some typical funerary objects like the Heart Scarab and the Ushabty
