Methodology for 3D acquisition of highly reflective goldsmithing artefacts

Abstract. The goldsmithing pieces conserved in museums are fragile objects whose accessibility for both research and mediation purposes lacks dematerialized systems for the safe handling of objects. The research presented is part of the e-thesaurus project whose main objective is to improve the accessibility of masterpieces of goldsmithing - produced during the medieval period in the northern regions of France and today’s Belgium - both for research and mediation purposes. The methodology for 3D acquisition of objects with high levels of details and reflective properties must be further developed and affirmed in order provide controlled datasets that are suitable for researchers of the field and accurate for mediation application. The proposed project is the result of a collaboration between the IRHiS UMR CNRS of the University of Lille and the University of Liège. The proposed methodology leads to the 3D reconstruction of masterpieces of goldsmithing. The models developed serve as a basis for a mediation through holographic representation. They recently participated in an exhibition in the Treasure of the Cathedral of Liège museum.e-thesauru

Projet SCIARPA, Formation initiale des architectes, Aide à la réussite Bloc 1, 1er cycle

L’objectif poursuivi par la faculté d’architecture n’est pas la réussite pour tous les apprenants à tout prix, mais plutôt de permettre : • A chaque apprenant de bénéficier des outils mis à sa disposition pour réussir, quels que soient sa situation et ses besoins spécifiques, tout en développant savoirs et compétences ; • Aux encadrants de maintenir le niveau d’exigences en étant partenaires de l’apprenant : trouver l’équilibre entre accompagnement et autonomisation. Le contenu du présent rapport de travail propose de s’adresser à l’apprenant en veillant particulièrement : 1. PRÉVENIR : à l’informer afin qu’il puisse choisir et s’engager en connaissance de cause ; 2. ENSEIGNER : à le placer au centre d’une formation lui donnant accès à toutes les ressources utiles au développement de ses compétences ; 3. DIFFÉRENCIER : à lui fournir un accompagnement personnalisé dans une institution humanisée. La question sous-jacente à la réussite de la 1re année du 1er cycle en formation initiale des architectes est la durée optimale des cycles d’apprentissage tant du point de vue des cours théoriques et/ou pratiques, organisés sur un quadrimestre, qu’en ce qui concerne le cours de projet d’architecture, organisé sur l’année par dérogation au Décret dit « Paysage »

peer reviewedThe digital documentation of heritage places produces accurate 3D restitution of their geometry in a virtual environment and can be related to multiple semantic layers to archive, represent, preserve and transmit the knowledge gathered along their lifecycle. The combination of high-density point clouds with other sources of information advises virtual reconstitutions of historical states of a place’s physical realm. The cultural significance of the built heritage lies in the values associated with its tangible and intangible dimensions. Apart from aspects of values related to historical sites’ physical attributes, 3D models can support the representation of intangible elements influencing visitors’ perception of their Genius Loci and supporting new interpretations about their cultural significance. In this framework, 3D animation, rendering, and simulation technologies allow recreating aspects of a place’s atmosphere, like the simulation of lighting conditions and the user’s immersive experience of a heritage site into a virtual environment. This paper focuses on the light perception recreated in a funeral chapel of the Theban Thumb environment by considering the strong spiritual dimension in the conception of funeral sites in Egypt during the New Kingdom period (1550-1069 BC). We investigate the potential of 3D simulation and animation technologies to represent hypotheses about original lighting conditions in such sites. The proposed research is based on the case study of Sennefer’s tomb, located on the western bank of the Nile, opposite modern Luxor

The volcaniclastic series from the luang prabang basin, Laos: A witness of a triassic magmatic arc?

International audienceThe paleogeographic evolution of South East Asia (SEA) during the early Mesozoic is still poorly understood and a number of models have recently been put forward to account for the geodynamic evolution of SEA. The Luang Prabang Basin (north Laos), located in the core of a “paleogeographic jigsaw” in SEA, recorded a long lasting volcanism that spanned for ∼ 35 my from the earliest Triassic up to Late Triassic as evidenced by combined stratigraphic and geochronological (U-Pb/zircon) analyses performed on both volcanic and volcaniclastic series. The volcanic rocks are arc tholeiites and calk-alkaline andesites to dacites. The volcaniclastic rocks contain, in part, volcaniclasts produced contemporaneously with sedimentation. Both the volcanic and volcaniclastic series display geochemical features characteristic of a subduction related volcanism. Therefore, the Luang Prabang Basin documents a magmatic arc in a good agreement with the recent recognition of neighboring ophiolitic rocks in the Luang Prabang area. Following a passive margin setting that prevailed from the late Carboniferous to the late Permian, an active margin then initiated along the western margin of the Indochina Block. This active magmatic arc developed as the result of an east-dipping subduction below the Indochina Block during most of the Triassic, at least from ca. 250 to 215 Ma. Subsequently, this oceanic subduction episode must have been followed by a continental collision of the Indochina Block with the eastern Simao Block, at a period that remains to be defined

CASTLE4D: AN ARCHAEOLOGICAL INFORMATION SYSTEM BASED ON 3D POINT CLOUDS

[EN] During the past decade, the implementation of 3D visualization and Geographic Information System (GIS) in archaeological research has increased and is now well established. However, the combination of these two factors remains rather complicated when faced with archaeological data. Some of the characteristics of this discipline impose the development of applications that will be able to cope with all of the specificities of archaeological data. Our research aims to create an Archaeological Information System (AIS) that will gather all of the characteristics of an archaeological work. In order to develop such an AIS, our first step was to identify its purposes and consequently, the features that should be available to the users. As it is destined to help with archaeological research, it is therefore of the outmost importance that the particularities of such a study are also taken into account. Moreover, the AIS is intended to incorporate point clouds that serve as a base for the three-dimensional model. These 3D point clouds result from the use of photogrammetry and/or lasergrammetry and, at a later stage, will be inserted into a GIS similar structure. The archaeological data will then be linked to the relevant section of the 3D model. However, these various stages and during the development of the AIS itself, we will encounter a series of issues that require to be addressed in order to produce a working system. This paper aims to identify and define the AIS characteristics as well as the issues and obstacles that we are going to face so that this system becomes a functional tool for archaeological research.Luczfalvy Jancsó, A.; Jonlet, B.; Hallot, P.; Poux, F.; Hoffsummer, P.; Billen, R.

Flash floods and muddy floods in Wallonia: recent temporal trends, spatial distribution and reconstruction of the hydrosedimentological fluxes using flood marks and sediment deposits

Flash floods and muddy floods may cause severe human and material damage despite their small spatial extent and low occurrence. In late May 2008, a major event has affected the area of Liège. This paper describes the methodology used to reconstruct the hydrosedimentological parameters of the flood from the geomorphological evidences observed in the field. Bed load and suspended load transport rates estimated during this extreme event were compared to the average values observed in other Walloon rivers and more specifically in the Ardennes Massif. The spatial distribution and the temporal evolution of the flash flood and muddy flood events are then analysed across Wallonia based on several works compiling press archives since the early twentieth century. The biases associated with this type of historical sources and the consequences of flash floods and muddy floods on the vulnerability and the risk of flooding in Wallonia are finally addressed.Les crues éclairs et les coulées boueuses, malgré leur extension spatiale réduite et leur occurrence peu fréquente, peuvent être à l’origine de dégâts importants tant sur le plan matériel que sur le plan humain. Fin mai 2008, un événement majeur a affecté la région liégeoise. Ce papier décrit la méthodologie employée pour reconstituer, en milieu forestier, ses paramètres hydrosédimentologiques à partir des éléments géomorphologiques observés sur le terrain. Les taux de transport de la charge de fond et de la charge en suspension au cours de cet événement extrême sont comparés aux valeurs moyennes observées dans d’autres rivières wallonnes et plus spécifiquement dans le massif ardennais. La répartition spatiale et l’évolution temporelle des crues éclairs sont ensuite analysées à l’échelle de la Wallonie sur base de plusieurs travaux académiques compilant l’ensemble des événements recensés dans la presse depuis le début du XXème siècle. Les biais liés à ce type de sources historiques sont abordés ainsi que les conséquences des crues éclairs sur la vulnérabilité et le risque d’inondation soudaine en Wallonie

Usages multiples d'un nuage de points 3D : le château de Franchimont (Province de Liège, Belgique)

peer reviewedThis paper presents the identified obstacles, needs and selected solutions for the study of the medieval castle of Franchimont, located in the province of Liège (Belgium). After taking into account the requirements from all the disciplines at work as well as the problems that would have to be tackled, the creation of a 3D point cloud was decided. This solution would be able to deal with the characteristics and needs of a research involving building archaeology and related fields. The decision was made in order to manage all of the available data and to provide a common working tool for every involved cultural heritage actor. To achieve this, the elaboration of an Archaeological Information System based on 3D point clouds as a common virtual workspace is being taken into consideration
