Fast tetrahedron-tetrahedron overlap algorithm
Ganovelli F., Ponchio F., Rocchini C.
We present an algorithm to test two tetrahedra for overlap. The algorithm is based on a dimension reduction technique that allows to apply the Separating Axis Theorem avoiding part of the computation needed to perform the Separating Axis Test. Source code is available online.Source: ACM transactions on intelligent systems and technology (Print) 7 (2003): 17–26.

Virtual Inspector: un applicativo per la fruizione interattiva di beni culturali
Ponchio F.
Il sistema Virtual Inspector consente all'utente non esperto di visualizzare un modello geometrico di grandi dimensioni interattivamente su standard pc. VI present il modello e tutti i dati multimediali che sono collegati a punti della superficie. VI impiega una interfaccia utente facile da utilizzare, basata sulla metafore point and click. L'efficienza in visualizzazione è ottenuta, senza sacrificare la qualità, utilizzando techniche allo stato dell'arte sulla rappresentazione a livello di dettaglio. Infine, l'uso di una codific aXML per la struttura dell GUI rende VI flessibile e facilmente configurabile

Visualization and 3D data processing in David's restoration
Callieri M., Cignoni P., Ganovelli F., Impoco G., Montani C., Pingi P., Ponchio F., Scopigno R.
The David restoration project (started in Florence in 2002) has given several guidelines to the definition and development of innovative solutions to process and visualize 3D data in the framework of Cultural Heritage (CH) applications. Our main goal has been to demonstrate the usefulness of digital 3D models and of visualization tools in the framework of a restoration project.Source: ISTI Technical reports, 2003

Teaching (digital) epigraphy
Lamé M., Ponchio F., Radman-Livaja I., Robertson B.
Although having the experience of directly manipulating an ancient textbearing artifact is important for developing the skills of an epigrapher - an experience that books and photo cannot replace - such access to primary sources is often problematic. In this article we present our experience with teaching students to transcribe and interpret Roman inscribed lead tags, using a Digital Autoptic Process (DAP) in a Web environment, so to develop basic competences in epigraphy and digital epigraphy.Source: Europeana network of Ancient Greek and Latin Epigraphy.

Batching meshes for high performance terrain visualization
Cignoni P., Ganovelli F., Gobbetti E., Marton F., Ponchio F., Scopigno R.
This paper describes an efficient technique for out-of-core rendering and management of large textured terrain surfaces. The technique, called Batched Dynamic Adaptive Meshes (BDAM) , is based on a paired tree structure: a tiled quadtree for texture data and a pair of bintrees of small triangular patches for the geometry. These small patches are TINs and are constructed and optimized off-line with high quality simplification and tristripping algorithms. Hierarchical view frustum culling and view-dependent texture and geometry refinement is performed at each frame through a stateless traversal algorithm. datasets.Source: Second Annual Conference of Eurographics - Italian Chapter, Milano, 25-26 settembre 2003

In this paper we describe the virtual reconstruction of a dismantled and dispersed piece of art: the Funerary Complex of Arrigo VII. To faithfully reconstruct the monument, all of the statues and elements of the mausoleum have been acquired in digital 3D format; then, with advanced computer graphics techniques, some of the accredited reconstructing hypothesis have been assembled and evaluated.Source: MIDECH 05 - Multimedia.Information@DEsign for Cultural Heritage, pp. 59–64, Milano, 5 aprile 2005

Evaluating the PileBar technique
Brivio P., Tarini M., Ponchio F., Cignoni P., Scopigno R.
Image browsing is an ubiquitous task, which becomes an issue as the number of images raises over a few tens. Amongst the wide spectrum of innovative image arrangements proposed in literature, conventional browsers still adopt regular layouts, which are more simple to interact with, but less suited for hundreds or thousands of images. We compare this kind of arrangement with that of PileBars, which is designed to be as intuitive, but more scalable. In our experiments, we evaluate if the PileBar image arrangements into ordered dynamic clusters effectively improve user navigation.Source: ISTI Technical reports, 2011

CENOBIUM - A project for the multimedia representation of romanesque cloister capitals in the Mediterranean region
Dercks U., Ponchio F., Scopigno R.
The online project CENOBIUM is a multimedia presentation of Romanesque cloister capitals. High-resolution digital photographs and 3D models will virtually link the capitals to their original surroundings, thus representing them within their original architectural and conceptual contexts. The project has the central aim to study artistic exchange in the twelfth and thirteenth centuries in architectural decoration. The first multimedia and multilingual online phase of the project has been freely accessible on the internet since 2007. The last update focused inter alia in an improved visualization and optimized interactivity of the 3D models by integrating WebGL technology.Source: EVA Berlin 2012 - Elektronische Medien & Kunst, Kultur, Historie, pp. 1–16, Berlin, Germany, 07-09/11 2012

Restoring David using 3D
Callieri M., Cignoni P., Ganovelli F., Montani C., Impoco G., Pingi P., Ponchio F., Scopigno R.
Refurbishing Michelangelo's David has produced several useful restoration guidelines. These guidelines can help restorers select the proper procedures for the task and, objectively, assess the results. The work also has helped us develop innovative ways to process and visualize 3D data in cultural heritage projects. The David restoration was an ideal test bed. We try various methodologies to support restorers and scientists with visualization tools based on 3D digital models. 3D digital models can be a tool for undertaking specific investigations, or as supporting media for archiving and integrating the restoration-related information.Source: IEEE potentials 23 (2005): 4–7. doi:10.1109/MP.2005.1368908

Il restauro della Fontana del Nettuno a Bologna - Un sistema 3D web per la documentazione e la gestione dei dati
Apollonio F. I., Basilissi V., Bitelli G., Callieri M., Catalano D., Dellepiane M., Gaiani M., Ponchio F., Rizzo F., Rubino A. R., Scopigno R.
In questo lavoro sono presentate le caratteristiche di un innovativo sistema di documentazione, realizzato per il restauro della Fontana del Nettuno di Bologna. Il Sistema Informativo usa un accurato modello tridimensionale per archiviare i dati raccolti in modo referenziato alla geometria 3D, per accedere agli stessi usando il modello 3D come indice spaziale ed infine per realizzare mappature direttamente sulla superficie dell'artefatto digitale analogo a quello dell'opera.Source: Archeomatica (Roma) 8 (2017): 30–34.

CENOBIUM 10 years after: an evolving platform for Digital Humanities
Dercks U., Ponchio F., Scopigno R.
The Authors present CENOBIUM, a web-based system designed to support the work of art historians. It provides access to multimedia content and related descriptive text on a specific topic: capitals in Romanesque cloisters. This paper discusses the motivation behind the decision to develop this web resource, taken more than ten years ago. It describes the initial design of the often system and how it evolved to keep pace with technological developments. In a context where the results of ICT & CH projects (digital tools, websites) have life span barely exceeding the timeframe of the actual project, CENOBIUM can be considered a success. It has been operating and steadily been updated with new content and latest technologies throughout its decade-long life.Source: Archeologia e calcolatori 2018 (2018): 123–141. doi:10.19282/ACS.10.2018.08

Visualizing and transcribing complex writings through RTI

This paper presents our digital publishing process and its editing system developed for a specific use case - the scholarly digital edition of a set of Roman inscribed lead tags - but suited for analyzing a broad variety of text-bearing objects. This pipeline covers the spectrum of the activities from data acquisition of the visual aspects to complex analysis of the writings and text of incised inscriptions. It employs a twodimensional medium, Reflection Transformation Images (RTI), to support visual analysis. The visual and textual data it generates are open access, ready to be used for machine learning processes.Source: CiST 2018 - IEEE 5th International Congress on Information Science and Technology, pp. 227–231, Marrakech, Marocco, 22-24 October 2018
