在傳統中國山水畫中，雲為非常重要的項目。山勢凝止必須流動的雲相伴才能活潑;而山巒厚重，必待雲的調配才能空靈。所以，在重賓主的中國畫中，筆墨不多的雲，更能產生調配虛實的效果。在本篇論文中，我們提供了一個三維水墨山水畫模擬系統，使用者可以互動式產生勾雲的線條，藉由調整筆刷的濃度及渲染度等，更能達到勾染並施之效。最後配合上系統產生之山石主場景，一幅中國傳統水墨畫儼然而生。

Clouds play important role in traditional Chinese Landscape paintings. Static gesture of mountains becomes vivid with floating clouds. The chain of mountains result in heaviness without the collocation of clouds. Therefore, clouds harmonize the real and imaginary components with limited pen and ink in Chinese paintings which place emphasis on the relation of guests and hosts. In this thesis, we provide a three-dimensional Chinese Ink Painting Simulation System. Users can generate the stream lines of clouds in outline style interactively. By adjusting parameters of brush model, like degree of ink consistency, degree of diffusion and so forth，we can attain both outline style and diffused effect in synthesizing cloud strokes. Joined together with the major scenery, a traditional Chinese Ink painting comes into being.
