3D animacija in fotogrametrija

KRIŽNAR, PIKA (author), Bovcon, Narvika (mentor)

V zadnjem desetletju se 3D animacija in fotogrametrija vse pogosteje uporabljata v filmski in multimedijski industriji. Ti tehniki omogočata ustvarjanje realističnih 3D animacij in modelov na cenovno dostopen način. Glavni cilj dela je bil raziskati možnost uporabe fotogrametrije pri izdelavi kratke 3D animacije. Namen je bil preveriti, v kolikšni meri lahko fotogrametrični pristop nadomesti klasično ročno modeliranje in hkrati ohrani kakovost končnega izdelka. Programska oprema Agisoft Metashape je bila uporabljena za fotogrametrično rekonstrukcijo, Instant Meshes za retopologijo in Blender za animacijo, osvetlitev in upodabljanje. Za montažo končnega izdelka je bil uporabljen program DaVinci Resolve. Celoten postopek je vključeval zajem fotografij, rekonstrukcijo modela, retopologijo, teksturiranje, skeletiranje in animacijo. Rezultat dela je kratka 3D animacija z naslovom Krila pohlepa (The Wings of Greed), v kateri je glavni lik 3D model fantazijskega zmaja. Analiza je pokazala, da fotogrametrija omogoča hitro ustvarjanje realističnih modelov, vendar zahteva dodatne korake, kot sta optimizacija in retopologija, da je model primeren za animacijo. Delo omogoča boljše razumevanje prednosti in omejitev fotogrametrije za potrebe 3D animacije. Postopek se izkaže kot primerna dopolnitev klasičnim metodam modeliranja ter ponuja potencial za uporabo v izobraževalne, umetniške in multimedijske namene.

Abstract

In the past decade, 3D animation and photogrammetry have been increasingly used in the film and multimedia industries. The techniques allow for the creation of realistic 3D animations and models in a cost-effective way. The main goal of this work was to explore the use of photogrammetry in the production of a short 3D animation. The purpose was to evaluate to what extent a photogrammetric approach can replace traditional manual modelling while maintaining the quality of the final result. The software Agisoft Metashape was used for photogrammetric reconstruction, Instant Meshes for retopology, and Blender for animation, lighting and rendering. The final product was edited using the software DaVinci Resolve. The entire workflow included photo capturing, model reconstruction, retopology, texturing, rigging, and animation. The result of this work is a short 3D animation titled Krila pohlepa (The Wings of Greed), featuring a 3D model of a fantasy dragon as a main character. The analysis showed that photogrammetry enables fast creation of realistic models but requires additional steps, such as optimization and retopology, to make the model suitable for animation. This work provides a deeper understanding of the advantages and limitations of photogrammetry for 3D animation purposes. The process proves to be suitable complement to traditional modelling methods and offers potential for application in educational, artistic, and multimedia contexts.
