MODELING MOVEMENTS ACCORDING TO MUSIC

To diplomsko delo predstavlja sistem za krmiljenje 3D modelov z glasbo. S pomočjo računalniškega programa Cinema 4D smo v ta namen izdelali 3D model z okostjem, ki smo ga v vizualnem programskem jeziku XPresso povezali z orodjem za obdelavo glasbe. Tako ustvarjen podatkovni tok omogoča samodejno gibanje 3D modela glede na ritmične poudarke v poljubni skladbi. Natančnost izvedenih gibov smo nadzirali z uporabo frekvenčnih filtrov, s katerimi smo izvedli tudi sestavljeno gibanje, ki spominja na preprosto obliko plesa. Ustvarjene animacije smo primerjali z videoposnetki podobnih gibov. Rezultati te primerjave so pokazali, da lahko s predstavljenim postopkom dosežemo zadostno stopnjo realizma, vendar pa zaradi pomanjkanja kontrole nad gibi ni mogoče posnemati vseh detajlov. Vseeno lahko s takšnim sistemom občutno poenostavimo delo oblikovalcem in tako zmanjšamo čas, ki ga ti potrebujejo za izdelavo animacije.This diploma work presents a system for controlling 3D models with music. With the help of a computer program Cinema 4D, we created a 3D model with skeleton, which we connected in a visual programming language XPresso with tool for processing music. Such data stream allows for the automatic movement of the 3D model according to the rhythmic accents in an arbitrary song. We controlled the accuracy of the animation with frequency filters and thus, we created compositions of movements, which resemble simple form of dance. By comparing the automated animation with real world videos, we showed that the presented method can achieve a sufficient degree of realism. Although we were unable to recreate several details due to the lack of control over the movements, such system could significantly simplify the work of designers and reduce the time needed for the production of animations
