本篇論文對於傳統的東方風格雲紋進行分析，歸納其中的生成規則與排列特性，並將雲紋圖樣作簡單的分類，發現雲紋圖樣具有自我相似與遞迴組成的特性，此點特性非常符合原本用於模擬植物生長的L-system，所以我們就針對所蒐集的眾多雲紋圖樣參考資料所分析出的資訊定義了一個適用於立體東方風格雲紋的生成生長規則，以L-system之技術為基礎進行撰寫規則語法，利用所定義結構化之規則循序地在三維空間中動態模擬雲紋的生長與變化。更進一步地，加入具時間序列的參數調整，可以使得雲紋隨著時間軸的變化產生東方風格立體動態雲紋。

Cloud Pattern is an important and common element in oriental decoration art, it is a challenge to extend the 2D abstract line into 3D objects. In this thesis, we try to induce the pattern generation rule and the feature of oriental cloud by analyzing the ancient oriental cloud pattern. We make classification from the oriental 2D cloud pattern, and discover the pattern is combined with symmetric, self-similar and repetitive features. These characteristic are the core of L-System, which is a suitable framework for plant growth and simulation, so we generate a new rule with specific parameter from the feature of 2D cloud pattern to generate oriental cloud pattern in 3-dimention space, simulating the growth of cloud and variety in structure. Further, we add the time temporal parameter to control the 3D oriental cloud pattern generation process dynamically.
