Digitising stećci – 3D documentation and relief visualisation of medieval tombstonesŠkerjanec, Luka (Avtor) Čaval, Saša (Avtor) Kokalj, Žiga (Avtor) stećcimedieval archaeologyphotogrammetrystructured light scanningvisualisation3D scanningrelief visualization toolboxThis study explores the medieval funerary phenomenon of ste´cci through advanced digital techniques. Employing photogrammetry and structured light scanning, we digitised a number of ste´cci to compare the effectiveness of these methods for accurate surface reconstruction. The comparisons have shown that both methods are capable of producing comparable models under optimal capturing conditions. A number of different smoothing and mesh refinement techniques were employed to remove surface deformations and make the carvings more visible. The use of surface-enhancing visualisations proved to be a prerequisite for accurate and reliable interpretation of the iconographic and epigraphic features on ste´cci. Among the tested visualisations, those based on Digital Elevation Models (DEM) were the most effective, with the Simple Local Relief Model (SLRM) combined with hillshading from three directions (HSMD) proving particularly reliable.20262026-03-23 20:45:21Neznano28557sl© 2026 The Authors
