Aumento do realismo na dramatização de storytelling com a criação de personagens que demonstrem emoções através de expressões faciais

Abstract

Computer graphics is applied in many areas. The Real-Time Computer Graphics is a sub-area used in entertainment applications like computer games and automatic display of narratives called storytelling. The realism in CG is highly explored within these applications, and realistic expression and natural representation of characters increase every day. This monograph describes part of a project that focuses on the three-dimensional graphic visualization of stories, represented by the development of an "intelligent" virtual camera able to perform the role of a director, that like in movies, determines the parameters to emphasize the story being told. In order to enrich the realism of these applications, this study proposes a technique to improve the emotional content of scenes, by creating characters that effectively represent their feelings by facial expressions, closely mirroring the creatures of the real world. This way, this work presents a representation of the character's face and an animation approach to ensure that different emotions may be represented according to the present action of the character or the plot. Thus, an improvement to the realism of the storyline is expected, making it more interesting and convincing to the eyes of the audience.
