“…Certaines approches abordent le thème de l'éco-conception intégrée aux outils de l'architecte dans la phase intermédiaire entre la conception architecturale ou urbaine [15,1]. D'autres enfin expérimentent des approches capables de simplifier la topologie des objets patrimoniaux enregistrés par photogrammétrie ou lasergrammétrie en exploitant les connaissances géométriques préalables des objets à enregistrer [12] ; ces méthodes ne s'appliquent cependant qu'à des objets patrimoniaux particulièrement bien conservés : c'est le cas par exemple de l'étude en cours au laboratoire MAP sur les plans-reliefs des villes fortifiées françaises des XVIIe et XVIIIe siècles, qui ont atteint un état de conservation souvent exceptionnel [1,6]. Dans le domaine de l'archéologie, la création de simulacres urbains multi-échelles peut répondre au besoin de représenter des réalités urbaines disparues dont on ne trouve aujourd'hui que des traces : au sol, il existe de nombreux vestiges enfouis, témoins de systèmes bâtis érodés par la succession incessante de transformations urbaines répondant aux usages changeants des pratiques sociales et individuelles.…”

Les champs disciplinaires de l’historien et de l’archéologue nous éclairent aujourd’hui de manière extrêmement documentée sur la « réalité » urbaine, architecturale et sociale des mondes disparus. Cependant, la plupart de ces travaux ne prêtent aux outils numériques de modélisation et de représentation de l’espace qu’un rôle « d’artiste éclairé » auquel on demande – au moment où l’on range les outils dévolus au relevé et à la fouille – d’illustrer les hypothèses retenues par ces éminents spécialistes de l’histoire. En effet, le processus de synthèse intervenant lors de la restitution finale de l’espace anthropique – mobilisant souvent des dispositifs techniques complexes et très spécialisés – entre en scène presque toujours en « bout de course » alors que l’harmonisation des apports scientifiques issus des disciplines afférentes au contexte de l’étude ont déjà en quelque sorte « figé » le panorama des hypothèses envisageables, notamment dans la restitution de la morphologie urbaine ou de la représentation de l’architecture vernaculaire. En prenant appui sur un vaste corpus iconographique représentant les espaces portuaires de la période impériale romaine et tirant parti de l’expérience menée autour du port de Portus, ce projet de recherche, financé par le Labex IMU, essaiera tout au long de son existence de briser ce tabou.

“…Some approaches address the theme of ecodesign integrated with the architect's tools in the phase between architectural or urban design (Marin et al 2012;Chevrier 2015). Finally, others apply operational approaches capable of simplifying the topology of heritage objects recorded by photogrammetry or lasergrammetry by exploiting the preliminary geometric knowledge of the objects to be recorded (Jacquot et al 2013); these methods apply only to particularly well preserved heritage objects: this is the case, for example, of the study under way at the MAP laboratory on the relief plans of French fortified towns from the 17th and 18th centuries, which have reached a state of conservation that is often exceptional (Chevrier et al 2015;Gros et al 2019). However, it happens that the very specific needs of a historical restitution require the implementation (design) of a dedicated tool using a specific pipeline capable of responding very precisely to the requests formulated by archaeologists or historians.…”

Digital Generative Tools for Restitution and Mediation for Cultural Heritage

Computer aided-design (CAD) tools should be able to assist the former exploration that leads the entire design process. However, current software often calls an immediate actualization of geometrical intentions by forcing the user with pre-set intentional clusters-geometric primitives, textural resources, design procedures etc.-often uncompromising, with poor intuitive feedback and generally restraining imagination spreadout: most CAD software act like over-equipped handdrafting assistants, assuming the maturity of the designer as much as the maturity of the project itself. What we aim to achieve is a computer-assisted generation process of architectural and urban plausible geometries. These self-generated objects are intended to act like "imagination enhancers" serving conceptual exploration of architectural design or providing credible 3D environments in given historical context. Next, this "pr-object" could not only be the ponderated completion of a pluridisciplinaric integration process but, in an autonomous evolution Darwinian paradigm, the actualization of the most performant genotype, or like Celestino Soddu says, a generative project is a concept software that works producing three-dimensional unique events as possible and manifold expressions of the generating idea identified by the designer as a subjective proposal of a possible world. Some of the research tasks depicted hereby take advantage of some generative methods developed within the MAP aria research team. They are able to quickly produce architectural and urban geometric simulations for contextual or historical restitutions. In the case of the Portus project, which required 3D modelling and rendering of the Ostia harbour complex at different times, generative design quickly established itself as a solution for dealing with the heterogeneity of the available scientific hypotheses.

“…Previous experiments were accomplished with Grasshopper for the architectural features extraction such as regulating lines, which are used to control the proportion and placement of elements in other proportioning systems as well [7]. Notable experiments of modeling based on the use of regulating lines include the military architecture features modeling such as bastioned fortification [8] and civil architecture features such as classical orders [9], [10] or gothic windows tracery [11], [12].…”

In architectural heritage field, the control over metric data is fundamental. Indeed the interpretability of geometrical concepts, the criteria and methods to structure information are the first step for the analysis and simulation for the conservation of ancient buildings. The main barrier is to move from survey raw data to 3D models that are understandable. To overcome this issue a knowledge-based approach is developed to carry out a reverse engineering for digitised masonry structures.
