本論文提出一個系統藉由輸入既有的中國山水畫，分析其流水筆觸的結構、配置密度以及濃淡來萃取畫作中的流動樣式，並且使用這些萃取資訊去產生一個速度場，並且將原圖畫中所萃取的筆觸組合適當放置在在場景中，產生山水流水動畫。也就是透過真實畫作直接產生中國流水動畫。本篇論文的主要貢獻在於透過數據驅動(Data-Driven) 的觀念，由現有的山水畫作中分析其畫作的資訊，並且利用該資訊萃取出流動樣式以及筆觸資訊產生流水筆觸資料庫，再使用流動樣式透過那維斯托克方程式(Navier-Stoke equation) 的物理模型來模擬大自然的流體流動，使虛擬流場能夠符合人們所認知國畫中的流動模式，並且透過波動方程(Wave Equation) 來模擬動態物體如船對於水面所造成的擾動，最後透過模擬出來的速度場由既有的流水筆觸庫中選取適當的筆觸來產生一部依據原畫產生符合流動模式的水墨流水動畫。

This work designs a data-driven system which takes an oriental painting as its input to analyze the structure, placement density, and ink density of strokes, generate a smooth flow field based on the extracted flow pattern, and places and animates strokes by choosing proper strokes from the extracted strokes according to the flow field in virtual world scene. The main contributions lie in the integration of a datadriven method which extracts the flow pattern and stroke style from an oriental painting and physical simulation for the creation of an oriental painting flow animation.
The physical simulation using the Naiver-Stokes equation to create static flow field and wave equations to simulate the disturbance among dynamic object and the steady water flow. The strokes is constructed and animated using the strokes extracted from the painting according to the flow filed.
