摘要

近年來3D虛擬角色的動作控制技術不斷的進步，但在製作連續動作上仍然耗費極大的人力及時間，音樂爲一個相當複雜且發展成熟的藝術型態，本身具旋律及節奏等元素，透過線性迴歸分析，能夠計算出音符沿著時間軸的線性關係，以數位音樂MIDI(musical instrument digital interface)作爲控制元素，對動作資料庫之動作進行對應，動作重新混合編輯產生新的角色動作，在此架構之下，動作不僅能自動產生，並且能透過參數的設定，讓角色動畫產生多樣性和可變性。

In recent years great progress has been made in the motion synthesis of 3D virtual human animation. However, this procedure still consumes a large amount of manpower and time. In this report, motion synthesis techniques in character animation are first described. Then, a new framework that integrates musical elements and motion-capturing data to synthesize realistic human motion is proposed. We analyzed the control elements with digital music and associated them with the corresponding motion-capturing data. Subsequently, the selected motion data were mixed by an editing program. Within this structure, the resulting movements can be not only produced automatically but also tuned through the controlling parameters. Linear regression analysis indicates the tendency of the melody, which can be an element for motion controlling the character. Therefore, character animation devised from a convenient source such as music can certainly and efficiently reduce the time and manpower required for animation.
