Lokomotion i ett gyllene snitt : En observationsstudie av naturtrogna och uttryckslösa kroppsrörelser med en metod designad för naturalistisk karaktärsanimation.

Sammanfattning: In aspiration to achieve naturalistic character animation, some difficulty does show up, both in 3D-CGI, 2D-CGI as in traditional handmade animation. The reason why difficulty appears in the task of achieving naturalism is for instance because of the simulated natural laws in the digital world which cannot affect the characters cinematic movement. The result of illustrating the natural law manually by hand can affect the illusion of the movement as not naturalistic or inconsistent, which can result in that the spatial adaptation to space is not perceived as naturalistic. It is most often up to the animator to make a believable illusion of the natural laws. This study examines a deeper understanding of the human way to behave and to adapt to the physical reality and through that, apply this movement on character animation. The purpose of a deeper understanding of movement's phenomena is to find a clearer method dedicated to naturalistic movement that can be adapted to all forms of character animation, regardless of the character anatomy. Unfortunately, it would not be possible to study all aspects of the physically adaptive behaviors as to the size of the topic. This study will therefore orbit the human locomotion, also known as walking. Focus will therefore be on the bottom part of the body, from the pelvis down to the ankles. There are scientists that do argue about a connection between the golden ratio and the human locomotion. This study is an attempt to apply the golden ratio on 3D-characters. This study has been devoted to a different approach in the character animation, where its starting point will be mathematical equations. For this study, it has meant an application of the golden section in a temporary form, that is in motion. The result is therefore a mathematically based method dedicated to imitating naturalistic movement in terms of time, that is to say human locomotion. The method has been proved to be useful even in the imitation of characters movements that do not possess human proportions.
