Do realismo ao cartum: sistematização de um modelo de conversão para captura de movimentos

Abstract

3D character animation is one of the technological fields where designers can work. It uses methods developed by traditional animation to deliver its productions. Since the 1970 s, however, another field has been developed alongside this process: motion capture. Initially rejected by animation professionals working in the industry today it is an integral part of it specially on certain types of production such as games and it is increasingly being used for producing animation. In this work a research involving motion capture and animation of 3D characters was carried out to prove our hypothesis and proposal of creating a semi-automatic motion capture cartoon system. We used as research method the model proposed by the University of Illinois and by it we went through the following steps: bibliographic survey about animation and its styles, aiming at the application in the proposed system and questioning the principles of animation (proposing a self classification); exploratory bibliographic survey in the field of computer vision, reporting the history of this area and the state of the art of motion recognition systems; motion capture using an electromagnetic equipment based system; an empirical experiment using motion recognition with a developed C# programming language algorithm, with Fuzzy logic applied to motion recognition and classification through natural language; cartoon movements application through previously know animation styles on motion capture in 3D animation software. As results we obtained: successful recognition of two similar captured movements (running and walking), their conversion into cartoon movements; a new proposal for animation principles classification; a proposal for animation classification.
