The design of the Politecnico di Torino “Campus delle Architetture, del Design e della Pianificazione” has an enormous strategic value, both for the reorganisation of the University and for the city dynamics, contributing to the overall development of the Po cultural axis. The transformation involved by the new campus will significantly impact the life of the area, radically changing its intensity through the daily flows of thousands of people and making the park an actual natural connective tissue. The communication project includes the realisation of events aimed at presenting the Campus to disseminate and popularise the outcomes of the realisation process to different stakeholders, showing a scale model of the area. Among the innovative features of the communication proposal is the superimposition of digital layers on the physical model for audience engagement through a webAR that activates a step-by-step journey with descriptions of different aspects of the campus project.
Artificial Intelligence and Extended Reality for Communicating the Uses of Natural Fibers in Building Construction: State of the Art and New Proposals
This contribution presents a digital framework to promote and communicate the use of natural fibers in building construction, developed within the “Circular Design for Natural Fibers” (CD4NF) project. The research addresses the limited application of advanced digital tools in this emerging field by proposing an integrated workflow that synergizes Building Information Modeling (BIM), Artificial Intelligence (AI), and eXtended Reality (XR). The core of the proposal is a flexible and modular platform built upon a structured material filing system that catalogs detailed information on various natural fibers. This platform utilizes BIM as a central data repository. An AI system, based on a Retrieval-Augmented Generation (RAG) model, enables users to query this complex data using natural language. XR applications provide an interface for visualizing and interacting with the BIM models and their associated information in real-world contexts. This approach aims to optimize key processes from material research and design to construction, enhancing decision-making, interoperability, and communication. The system represents a step towards a more efficient, circular, and sustainable construction sector by facilitating the informed adoption of natural fiber-based materials.
Castello di Mirafiori: Reconstructive Modelling and WebAR
This paper presents a digital heritage project focused on the reconstruction and public communication of the lost Castello di Mirafiori in Turin through 3D modelling, WebAR, and physical prototyping. Developed through a collaboration between Politecnico di Torino and the Municipality of Turin within the European proGIreg urban regeneration programme, the research combines archival drawings, cadastral maps, engravings, historical texts, and territorial cartography to reconstruct the morphology of the Savoy residence and its formal gardens during their period of greatest splendour between the late sixteenth and mid-seventeenth centuries. The resulting digital model was optimized for lightweight online visualization and integrated into a browser-based augmented reality application using open-source AR.js technology, allowing visitors on site to access the reconstruction via QR code without installing software. Users can superimpose the castle model onto an information panel and explore different scales and views. The project also includes the design of a tactile physical model produced through laser cutting and 3D printing. The study demonstrates how low-cost AR solutions can reactivate vanished heritage, support community engagement, and contribute to cultural-led urban regeneration.
Reconstructive 3D Modelling and Interactive Visualization for Accessibility of Piffetti’s Library in the Villa della Regina Museum (Turin)
This research is realised in the framework of a project recently funded as part of the PNRR (National Recovery and Resilience Plan) in the Accessibility sector. The working team has been established in the framework of the scientific agreement between the Museum of Villa della Regina in Turin, the Department of Architecture and Design at Politecnico di Torino, and the Department of History, Drawing and Restoration of Architecture at Sapienza Università di Roma, and includes knowledge from art history, digital surveying, 3D modelling, and digital solutions for cultural heritage. The research involves the reconstructive 3D modelling of Piffetti’s Library, once placed in the cabinet toward midnight and west inside the Villa della Regina and today in the Palazzo del Quirinale, and its interactive visualisation through augmented reality (AR) and virtual reality (VR) aimed at accessibility.
