Predmet diplomske naloge je z metodo študije primera raziskati pomen ra\-čunalniških tehnologij, informacijskih metod, računalniških programov, 3D modelov in 3D grafičnih programskih orodij v arheologiji. Naloga je osredotočena predvsem na primerjavo in analizo parametrov petih 3D modelov paleolitske lesene konice v izbranih formatih (PLY in STL), ki so bili narejeni v časovnem intervalu 2009--2018. Primerjalna analiza podatkov in parametrov vseh 3D modelov je bila opravljena z odprtokodnim računalniškim programom CloudCompare. Dobljeni rezultati ter opravljene primerjave so potrdile začetno hipotezo o spremembah, ki so nastale na artefaktu po njegovem odkritju in izločitvi iz njegovega naravnega okolja. Ugotovljene razlike in spremembe (npr. upogib in deformacija, spremembe v teksturi in preseku, ipd.) so nazorno izpostavile nevarnost neželenih sprememb in degradacije arheoloških ostalin kopenske in podvodne kulturne dediščine po njihovi izločitvi iz naravnih pogojev najdišča. Izbrana programska oprema je izpolnila pričakovanja o njeni primernosti, uporabnosti in koristnosti pri arheološki analizi in vrednotenju ostalin kulturne dediščine.

The subject of this dissertation was to investigate the importance of informatics, computer technologies, computing methods, computer programming, 3D models and 3D graphical software tools in archaeology and in interdisciplinary archaeological treatises, analyzes and evaluations of the artefacts and the past cultural heritage using case study. The task is focused primarily on the comparison and analysis of the parameters five 3D models of the paleolithic wooden artefact in the given formats (PLY and STL), which were made in the time interval 2009--2018. A comparative analysis of the data and parameters of all 3D models was carried out with open source software CloudCompare. The obtained results and the comparisons made confirmed the initial hypothesis of changes that occurred on the artefact after the discovery and exclusion from its natural environment. The differences and changes found (for example: bending and deformation, changes in texture and cross-section, color, etc.) highlighted the danger of unwanted changes and degradation of archaeological remains of land and underwater cultural heritage after their removal from the natural conditions of the site. However, the selected software fulfilled the expectations of its suitability and usefulness for archaeological analysis and for evaluation of the cultural heritage in general.
