MUSCLE MOVEMENT IN 3D ANIMATION

V diplomskem delu obravnavamo pristope k 3D modeliranju in animacij mišic človeškega telesa. V ta namen najprej predstavimo fiziološko ozadje njihovega delovanja ter podamo osnovne anatomije mišic, njihove sestave in delovanja. Podrobneje predstavimo sile, ki lahko vplivajo nanje in preučimo spremembe mišic, ki jih povzročijo. Pri tem se skoncentriramo na vrste mišičnih kontrakcij ter opišemo njihove lastnosti. Temu sledi opis obstoječih tehnik za ustvarjanje mišičnih animacij, problemov, s katerimi se soočajo animatorji in trenutno stanje tehnike na tem področju. V praktičnem delu smo ustvarili realističen model mišičnega sistema človeškega telesa, katerega pravilnost smo preverili na primeru fiziološko eksaktne animcije telovadnih vaj.These diploma thesis studies approaches for 3D modelling and animation of human muscles. For this purpose, we first describe the physiological background of the muscular system, the basic anatomy of the muscles, their structure and behavior. We, furthermore, examine the forces affecting the muscles and how they change in regards to the forces acting on them. We describe the different types of muscle contractions and provide a detailed presentation of their characteristics. It is followed by a description of the existing techniques for creating muscle animations, the problems animators are facing during the implementation and the current state-of-the-art. As a practical example, we created a realistic model of the muscular system of the human body and demonstrate its accuracy by animating the physiologically correct muscle movements during gymnastic exercises
