3d Modelling and Medieval Lighting Reconstruction for Rupestrian Churches

Abstract

<p><strong>Abstract.</strong> The aim of this research is to define a method, able to analyse the systems of illumination in the medieval period, through a 3D virtual model reconstruction. It specifically needs to deepen the interactions between natural and artificial illumination in confined spaces. The study describes and examines the best survey technique to obtain a 3D model reconstruction, according to the achievement of such lighting scenarios, and the most suitable tools for lighting analysis. Thus, it is possible to carry out accurate interpretations of the past starting from historical sources and scientific data about lighting. This method was validated on a case study of a rupestrian church in Matera. The rupestrian contexts are less investigated in relation to mediaeval artificial lighting even if there are recognitions and comparative studies of widespread contexts, not only in Puglia and Basilicata, but also in Mediterranean area (e.g. in Cappadocia and Cyprus) which allow identifying evidences related to artificial lighting systems. The architectural signs (hole, niches, etc.) for ancient luminaries can be studied in 3D and lighting prospective. Lastly, the virtual model of the rupestrian church was imported into an opensource visualisation software (3D Heritage Online Presenter) to be appreciable on line and to promote historical heritage knowledge.</p>

Digital Preservation of Du Fu Thatched Cottage Memorial Garden

“…Moreover, the application and cross integration of digital photography, terrestrial laser scanning, unmanned aerial vehicle photogrammetry, and other technologies [18][19][20][21][22] have brought new opportunities for the conservation of classical gardens by recording rich spatial elements and cultural connotations. The use of efficient, comprehensive, and detailed mapping technologies to establish visual, accurate, and comprehensive point cloud models [22], 3D models [22][23][24], solid models, and other virtual models [24][25][26] can provide important baseline data for digital archiving [19,22], quantitative analysis [27], earthquake damage simulation [26], real-time monitoring, VR scenes, digital twins, and the metaverse construction of realistic garden scenes while promoting the value of cultural heritage preservation and natural scenes for sustainable conservation, science education, and exhibitions. Taking Du Fu Thatched Cottage as an example, this study introduces digital conservation research, which is of importance as a reference value for the study of the conservation of classical gardens including historical and cultural celebrity memorial gardens in Xishu.…”

Methods of Conserving and Managing Cultural Heritage in Classical Chinese Royal Gardens Based on 3D Digitalization

“…The shift from one-way heritage information release to multidimensional information interactions and strengthened interactions based on human perspective. The interaction among multidimensional information becomes a digital cultural heritage information service [40, [48][49][50][51].…”
