Abstract

What is important in this study as the main purpose, is face believability in 3D computer animations. To examine this, the importance of face has been discussed according to four perspectives as follows: face reading and face language, body language and face position in it, the importance of face in communication and finally the importance of sense of sight. The reason for focusing this paper on 3D animation, in addition to the personal concerns of the authors, was to find a way to translate that trusted facial element into faces in 3D animation. Another reason for focusing on this type of animation is its increasing popularity in various areas due to its high flexibility, which continually changes its aesthetic boundaries.
There are some presented numbers which show that even in the simplest models of communication, the face plays the most crucial role in conveying emotions. The notion of believability in computer animations and, subsequently, face believability, is another subject examined on the basis of Curie and Kania's view as the real motion picture, which provides a basis for the best description of real 3D computer animations. According to the concepts mentioned above, we try to provide solutions to enhance the believability of the faces in the animations alluded. The animator must know his character so well that he can recognize his personal reality in the moment. It is the role of the animator and his skills as an actor that can provide the audience with believable characters. This is more important in the face because it is the source of emotion and the believability of the emotion is very important to the audience.
Uncanny valley, the most critical challenge of face believability in 3D computer animations, is also examined. What follows is an examination of two opposing viewpoints: one considers the universality of emotions to be true and the other considers it basically to be false. This study provides an opportunity to achieve practical solutions for the creation of believable faces. In the end, acting in animation is explored as an important element in conveying emotions to the audience; and attempts are made to develop methods of acting so that it helps to enhance the believability of the face. The results of this article show that humans are able to read each other's body language, and since the face conveys full meaning when it comes to emotions, it has a special place in body language and the believability of 3D animated characters. In addition to the method of Acting, Kennedy's perspective on acting, inspired by the concept of Morris, was also discussed in this article. Finally, it should be noted that what is most important in acting is the believability of character emotions. This is especially important when it comes to photographic realism.If the character's face is designed in harmony with its intrinsic characteristics, it will likely have a better chance of conveying the emotions to the audience. This can help character designers in animations to create more believable characters.
