“…In the domus or in the villas, the roofs were mostly made with double or quadruple pitches since they facilitated the outflow of rainwater [38]. The structure, with a sufficient slope, was built with wooden decks.…”

Through a non-contact survey methodology, based on image-based techniques, the authors digitally ‘build’ a three-dimensional hypothesis of a monumental complex carved on a first-century AC marble tombstone. Guided by the mathematical rationality recognised in the artefact, the paper illustrates the reasons for the reconstructive choices and then proposes a reflection on the architectural contents. The ultimate goal focuses on the potential use of the digital product, which, thanks to and by virtue of the use of dedicated platforms, promotes strategies that include identity values by superimposing technical, social, and economic aspects. The setting up of collaborative spaces programmed with different strategies can effectively support the cognitive experience by verifying the possibility of “remedying” contents that, in our case, direct the study, dissemination, and protection of cultural heritage according to the most recent UNESCO recommendations.

“…This element is a major one for the construction of a procedural model, because it organises through a radial array the series of circular and rectangular niches forming the mixtilinear pattern of the building. The advantage of a procedural approach is relevant once the model is compared to non-uniform contour lines, obtained by means of reverse modelling applications (Cipriani et al, 2014a). Another major aspect of procedural modelling, facilitating creation of common formal rules linking plan and elevation, is the presence -in the general layout of Roman buildings -of grid-based design.…”

<p><strong>Abstract.</strong> The paper compares two workflows for the achievement of 3D models aimed at in-depth studies on the geometric features of Cultural Heritage artefacts and their dissemination. The purpose is the outlining of pros and cons of different techniques coming from entertainment and video games industry, starting from highly reliable 3D documentation of cultural assets, i.e. architectural/archaeological/urban sites. Two different possible applications are described: (i) procedural modelling used for understanding and visualising reconstruction hypotheses of the vaulted pavilions at Hadrian’s Villa, Tivoli, Rome; (ii) optimisation of 3D high-detailed models, as input files, turned into visual reliable and highly portable assets for game-engines. The first case study is focussed on creating a flexible model for evalueting reconstruction hypotheses and supplying restorers with useful hints for shape completion of ruined pavilions. The second case study makes available detailed digital contents for storytelling historical and cultural events in an attractive way, as in the case of the urban explorative model of Chiuro, a small town in northern Italy.</p>

“…The transition from 3D to 2D representation, with the related geometric transformations, has not yet been fully formalized and still features open issues, e.g., in the case of planar development of frescoed vaults [28]. Methodologies proposed so far on this subject provide transitioning from point cloud models to known mathematical surfaces (developed on plane, or not), and afterwards seeking an ideal representation of the actual surface, losing some architectural and building details in this process [29][30][31][32][33]. To the best knowledge of the authors, modeling and reverse engineering software commonly used do not have dedicated tools that enable automatic development of geometry and textures.…”

Abstract:In the field of documentation and preservation of cultural heritage, there is keen interest in 3D metric viewing and rendering of architecture for both formal appearance and color. On the other hand, operative steps of restoration interventions still require full-scale, 2D metric surface representations. The transition from 3D to 2D representation, with the related geometric transformations, has not yet been fully formalized for planar development of frescoed vaults. Methodologies proposed so far on this subject provide transitioning from point cloud models to ideal mathematical surfaces and projecting textures using software tools. The methodology used for geometry and texture development in the present work does not require any dedicated software. The different processing steps can be individually checked for any error introduced, which can be then quantified. A direct accuracy check of the planar development of the frescoed surface has been carried out by qualified restorers, yielding a result of 3 mm. The proposed methodology, although requiring further studies to improve automation of the different processing steps, allowed extracting 2D drafts fully usable by operators restoring the vault frescoes.
