碩士 === 國立雲林科技大學 === 視覺傳達設計系碩士班 === 93 === This study is mainly aimed to investigate the 3D animation facial expression by means of research investigation. We attempt to understand the most frequently seen facial complexion when 3D animators are producing facial expression and the most difficult facial expression for them to catch. To sum up the most representative facial expression samples so that it is available for the reference in 3D animation production and education activities. This research is divided into 4 stages. The 1st stage is to gather the vocabulary of facial expression. By referring to the scientific lectures relevant to psychology, performance art, computer animation and facial expression, we can gather and compile the vocabulary of facial expression to act as the basic reference for convergent vocabulary of next stage. The 2nd stage means the vocabulary convergency of facial expression. Through 30 3D animators or researchers, we adopt the voting survey to screen out “the most frequently seen facial expression” and “the most difficult facial expression for them to catch. The 3rd stage means the screening selection of facial expression production and the representative facial expression. Through 6 performers, we can proceed the intentional setting of complexion in vocabulary convergency. Furthermore, through the practitioners relevant to computer 3D animation and the public viewers of 3D animation, we adopt the ranking method to screen out the most representative facial expression. Meanwhile, we also investigate if there is any diferrence existing within the ample ranking among the examinees from various professional backgrounds. The 4th stage is aimed to analyze the characteristics of facial expression. By referrring to the facial expression comparison proposed by Paul Ekman, we can proceed the analysis of representative samples. The research results are briefed as below: 1.With the reference of scientific lectures to gather the vocabulary of facial expression, there are totally 649 vocabularies gathered (including repeated vocabularies). Furthermore, through the most frequently seen facial complexion screened by 3D animators, there totally vocabularies gathered, namely vexation, smile, fear, merriment, disappointment, amazement, sadness, excitement, outrage, and fatigue. The most difficult facial expression for animators to catch and imitate are totally 9 vocabularies, namely lust, compliment, arrogance, envy, alertness, recall, embarrassment, obedience and stubbornness. 2.The ranking orders for the most frequently seen facial expression of animation roles voted by examining from various professional backgrounds are almost the same. Although it really exists in difference about the ranking orders of the most difficultly imitated facial complexion made by animators, the difference is not so remarkable as we suppose. On the whole, the ranking orders of representative samples voted by the examinees are of the same opinion. 3.We summarize 19 sets of facial expression characteristics to act as the reference table so that it is available for the facial expression production made by 3D animators. The table contents include the most personality -representative complexion of each vocabulary, the muscular trend of 3D facial expression model, the description of complexion characteristics and Type A & B grouping samples proposed by Duncan.
