摘要

角色動畫是3D軟體學習過程的一個技術門檻，製作角色動畫，需要熟練的3D技術，對“時間與空間＂關係感受敏銳的天賦，因此只有少數的學生可以調出台宜的角色動作，呈現鮮活的表演。動態擷取系統在影視動畫產業的運用早已司空見慣，電影工業甚至整合了演員動作、臉部表情與攝影機鏡位同步擷取資料，近年來大型製作的高階遊戲，其遊戲內的角色動作也多使用動態擷取資料，可見動態擷取對於提升製作速度與品質之幫助。由於多數的動態擷取系統系統設置費用高昂，需相當的使用技術與經驗，考量設備折損率，學校中多半是老師和研究生才能夠操作運用，對於多數學生來說動態擷取系統屬於遙不可及的高階設備。開設的“數位動作捕捉實務＂課程，解說動態擷取系統的發展、分類與應用方式，課程上則讓每個學生都實際操作與應用光纖式動態擷取系統，了解動態擷取系統在角色動畫製作的過程中，所能提供的協助與不足之處，輔以影像辨識式的動態擷取系統作為對照，最後讓學生將動態擷取資料應用於動畫製作中，確實提升角色動畫的製作速度與品質。

Character animation represents as the entry skill requirement when learning 3D animation. In order to well adjust motional performances of characters, it is essential to have good 3D techniques, experienced on 2D animation and be sensory acuity on time-speed relationship. Most students are still in the stage of modeling practicing, texturing, and lighting. Only a few students are able to create characters with proper motions which would present emotion of characters. It is common to apply motion capture system in film, television and animation industries. Recently, AAA rating games also use motion capture system while producing motions of characters. Hence, motion capture system improves the speed and quality when producing. Due to the high installation cost, and requirement of sufficient skills and experiences, under the consideration of equipment of attrition rate, only lectures and graduate school students are allowed to operate this system. Therefore, for many students, motion capture system is still a high-end facility. Therefore, program of digital motion capture practice is held to illustrate the development, category and applications of motion capture system. In the class, students understand support they can get from the system and the insufficient part of the system through practical operation of fiber motion capture system. However, the correctness of motion capture data is not considered during the class, combined with image-base motion capture system as a control, Finally, let students use MOCAP data in animation production, it is indeed enhance production speed and quality of character animation.
