水墨畫家在作畫時，先選擇優美的山水景色作為構圖，再據以構思創作，完成氣韻生動的中國山水畫。雖然從單張的山水畫作能夠取得場景的結構和外觀，但卻無法從不同的角度來觀看整個場景。在論文中，我們提出一個可以從任意視點觀賞中國山水畫的方法。經由對中國山水畫構圖的分析，定義山水的立體基本模型。使用者先輸入參考山水畫作，再指定山水外觀參數，系統便能自動建立和參考畫作相同場景的立體模型。使用者可以在場景中自由地遊走。在決定好觀看場景的位置後，由電腦輸出不同於原來參考畫作觀看角度的中國山水畫。如此，使用者只需輸入單張的山水畫，就能從各個不同的角度來觀賞原畫作所要呈現的三維山水景物。

Chinese artists capture the spirit and true beauty of the landscape to paint a Chinese landscape painting. But while a single Chinese landscape painting gives us an amazing amount of information about the scene’s structure and appearance, it is a static frozen picture. What we have lost is the ability to look in different directions and to move about in the scene. In this thesis, we propose a method to view a Chinese landscape painting from an arbitrary viewpoint. We analyze the composition of Chinese landscape painting and define 3D basic primitives of mountain and water. First, the user inputs a reference picture. Then according to the feature parameters of 3D basic primitives specified by the user, our system automatically generates a 3D scene model which is the same as the scene of reference picture. The user can move to anywhere in the scene. After the user determines the viewing position, our system outputs a picture whose viewpoint is different from the original picture.
