傳統的裝飾紋路，如獸面紋和雲紋，是經過工匠藝術家將其對於自然的變化與鳥獸的形態加以抽象化，藉由這些精妙的花紋傳遞豐富的訊息，形成具有象徵意義的紋路。本論文針對傳統中國雲紋進行分析，發現其保有高度的自我相似性，以此特性為基礎，我們發現到L-system也常被運用於此類特性紋路之創建，本論文以此語法為基礎撰寫生長規則，配合parametric L-system參數化的特性，不但可以讓雲紋達到很好的多樣性，同時配合非相片寫實電腦繪圖技術強化風格效果，讓我們的結果更忠於傳統雲紋，更進一步透過具時間序列的向量場資訊影響L-system之成長，產生具東方風格之動態雲紋。 / Traditional decorative patterns, such as animal mask and cloud patterns, are the art heritage from the abstraction of the changing nature and the shape of animals. These decorative patterns are not only exquisite art, but also meaningful symbolic patterns. In this thesis, we analysis the traditional Chinese cloud patterns, and find out the structure of self-similarity in cloud pattern. In this thesis, we design the growth rules base on the grammar of L-system and the parameterization of parametric L-system. We also combine the stylized line drawing to achieve a good variety of cloud patterns, and our results are faithful to the traditional art. Furthermore, we can generate the dynamic oriental cloud patterns with a time-varying vector field to affect the growth rule.
