本論文提供一種方法，讓使用者以簡單繪製二維平面線條的方式，不需提供高度資訊，不需在多視角下編輯，即可建立出簡單的三維模型。系統會分析使用者所繪製的線條，將線條形成的輪廓像充氣一般的從二維平面使其鼓起成三維模型，並對使用者所描繪的內部特徵區域做處理，使模型產生明顯的額外特徵。此外藉由筆刷的壓力資訊，可會對模型的外觀產生影響，提供更多變的控制。系統並提供一個介面讓使用者以繪製線條的方式對建立出來的模型做變形並編輯動畫，配合貼圖處理之後，便可輕易產生一段生動有趣的動畫。

　In this paper, we present a system that let the user perform modeling, deformation and animation of 3D mesh model using strokes under one single view. User can build model using a combination of outlines, internal feature lines, shadow information and skeleton lines like drawing on conventional 2D canvas. Deformation process is simple and intuitive by specifying the target bone location or the desired outline of deformation result. Animation is controlled using motion strokes that indicates both timing and the interpolation path. Our system is easy to use and produce adequate results using only strokes as the input to the system.
