“…An AR application available for mobile devices, is introduced by (Scianna et al, 2020) and includes the visualization of the Wignacourt fountain in its initial position, in St. George Square in Valletta. Banfi et al (2019) have implemented VR technology to enable the monitoring of the restoration works in Sant' Ambrogio church in Milan and present its complex historical phases. The VR simulation of Santa Maria Delle Grazie, constitutes an immersive experience, which integrates audiovisual and interactive tools, ensuring a high level of realism (Bolognesi and Aiello, 2019).…”

Abstract. Virtual Reality technology has already matured and is capable of offering impressive immersive experiences. AT the same time head mounted devices (HMD) are also offering many possibilities along with the game engine environments. So far, all these impressive technologies have been implemented to increase the popularity of on-line visits and serious games development, as far as their application in the domain of Cultural Heritage is concerned. In this paper we present the development of a set of VR tools, which enable the user to perform accurate measurements within the immersive environment. In this way we believe that these tools will be very helpful and appeal to experts in need of these measurements, as they can perform them in the laboratory instead of visiting the object itself. This toolbox includes measuring the coordinates of single points in 3D space, measuring three-dimensional distances and performing horizontal or vertical cross sections. The first two have been already presented previously (Kontos & Georgopoulos 2020) and this paper focuses on the evaluation of the performance of the toolbox in determining cross sections. The development of the tool is explained in detail and the resulting cross sections of the 3D model of the Holy Aedicule are compared to real measurements performed geodetically. The promising results are discussed and evaluated.

“…The static laser Faro Focus 3D was employed in different survey phases. The 3D scans were registered with an average precision of ±3.0 mm by using targets, topographic measures and with additional scanto-scan correspondence (spherical targets) (Banfi, Brumana, & Stanga, 2019a). The fieldwork required almost 3 hours work for scanning and 40 min for the topographic measures supporting the LiDAR survey (considering already measured topographic network vertices, and only detail survey execution on them), and this is, as usual, a time-consuming procedure.…”

In the wide framework of Scan-to-BIM 3D modelling procedures, the complexity of the architectural heritage and its components is evidencing a gap of best practices and specification in the HBIM-modeling and thus it is requiring important considerations about the modelling strategies and protocols between the requested level of detail (LOD), the expect accuracy and above all the actual use-oriented requirements. Several works are largely focusing on developing workflows for traditional static LiDAR scanning sensors. However, the chance to benefit from on-site faster data acquisition is needful at times, and procedures are directing toward rapid mapping 3D approaches, evolving from traditional static scanning toward MMS (Mobile Mapping Systems) based on SLAM technology (Simultaneous Localization and Mapping) algorithms implemented in portable devices. The potential of these solutions can contribute to increase a massive cost-effective documentation, and also in view of BIM-HBIM modelling generation, and this needs further researches. At the same time, the descriptive capabilities of this class of portable scanners do not reach the precision of the static solutions. Many time-cost balance evaluations towards an analysis of geometry, grade of generation (GOG) and details can be thus conducted. This paper presents a first comparison between TLS (Faro Focus 3D) and hand-held scanner Zeb Revo (by GeoSLAM) of the entire workflow (from raw data acquisition up to parametric modeling) focusing on the Bramante’s Canonica Court in the Basilica di Sant’Ambrogio. First, the two raw data are compared, considering geometric features (data density, precision, possibility to detect edges, details and accurate curvature). Then, some well-established modelling procedures developed for TLS data, as triangulation mesh and NURBS generation, are applied to MMS point cloud to identify their suitability. Different elements belonging to the architectural structure hierarchy are considered in a multi-scale perspective: the vaulted system of the porch, the columns and the arches of the porch with their different architectural elements.

Abstract. The 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 Tomb environment by considering the strong spiritual dimension in the conception of funeral sites in ancient 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 chapel, also referred to as TT96A, located on the western bank of the Nile, opposite modern Luxor.
