Sensitive Floral v2

an interactive generative organism built with L-system recursion and cellular-automata-inspired local rules, where touching a single branch triggers real-time propagation across tens of thousands of branches.





Sensitive Floral extends L-system morphogenesis beyond structural growth by embedding a locally propagating state field within its rewriting grammar. Rather than treating the L-system as a fixed binary branching model, the work approaches it as a generative language space capable of producing diverse morphogenetic vocabularies. The dense, radiant visual structures seen in the animation emerge from recursive rewriting and iteration depth, where growth is organized as a developmental sequence rather than decorative accumulation.

Within this morphogenetic scaffold, a cellular automata–like mechanism operates as a local state field. State transitions are not computed on a traditional grid but transposed onto the adjacency relations of the L-system structure. When a branch’s state shifts, angular modulation and folding behaviors propagate through neighboring connections, producing dynamic reconfigurations that unfold in time.

Touch interaction does not trigger pre-scripted animation. It introduces local perturbations into the behavioral field. These perturbations diffuse, accumulate, and reshape the organism’s temporal rhythms. Two calibrated boundary conditions—open and closed—remain structurally defined, while the transitional process between them retains a degree of unpredictability. Control is thus framed as boundary-setting rather than command execution.

Through this coupling of generative grammar and reactive state propagation, Sensitive Floral presents a touch-responsive virtual organism in which morphology and behavior continuously rewrite one another. The work foregrounds morphogenetic visual density and embodied interaction, inviting viewers to engage with growth as both a computational structure and an experiential field.

在仿生媒體(Biomimetic Media)領域(Weibel, 2023),近年來發展了以電腦運算系統模仿生命運作機制的創作表現方向,並藉由以感測器與外在實體世界的觀者進行對話,讓這些仿生演算法被設計除了再現生物的型與特徵外,更能與觀者進行直覺的互動。例如,衍生設計(Generative Design)和代理機制(Agent Mechanisms)等概念發展的仿生演算法(Biologically Inspired Computing),近年來更被提出許多作為人工生命(Artificial Life)的藝術表達的創作發展(Ohlenschlager et al., 2023),蔚為當代藝術重要的發展面向。

延續本人先前的創作《Hybrid Dandelion》(Huang & Hsiao, 2019),在《Sensitive Floral》 作品中,我借鑑了數學細胞自動機(Cellular Automata)產生突顯行為的特質,將其網格計算(Grid Computing)機制建構於二元碎形樹(Fractal Tree)資料結構發展的衍生設計圖像系統中。建構一種樹枝結構與其相鄰分支(包括與迭代層次中上一層的父母輩分支、平行迭代層次中的同輩分支,以及下一層迭代中的子女輩分支)之間可調適性的交互關係。這樣特殊的樹狀結構,驅動內部的區域性的資訊交換(Local communication),以此同步展現與外部觸發的交互關係。透過這樣的觸發性與擴散性的細胞運動反應機制(Diffusive Cellular Motion Response)的研究探索,發展出貼近在含羞草(Mimosa pudica)在生物學研究上,所發現葉片在集體動態反應中的細胞運作機制 (Hagihara et al, 2022)。

此外在參數設計應用在數據驅動蒲公英圖像生成的規則設計中,從二元碎形樹與歸遞機制研究,發現單一規則參數的改變,影響迭代性的整體造形調適性的連動變化,這樣自我組織性的交互效應,由下而上猶如細胞分裂般的影響,發展出多樣性仿生紋理。從遞迴、對稱性、碎形樹等演算法的應用,以及參數與規則設計等機制,發展仿擬花意象與美感表現,強調在「形態異變」、「花開」、「生長」等花的意象視覺表現。在衍生系統的設計中,依照靜態與動態美感的標準,重新定義了線條的表現參數(粗細與透明度)與其迭代階層的狀況,建構關聯性的規則。並在動畫的生成、動態視覺的表現上,重新以視覺表現的角度增加了程式的運作機制,以此發展仿生美感。

《Sensitive Floral》 是一件可互動的即時衍生圖像裝置,企圖建立虛擬人工生命(Artificial Life)圖像內容與賞者即時互動,透過手指觸摸觸控螢幕上樹狀結構的枝節,引發由網格運算(Grid Computing)產生的反應機制,模仿生物 (參考生物學中含羞草的動力細胞的運作)具調適性的連續性動態行為。背後是利用數學細胞自動機(Cellular Automata)網格運算的機制設計,探索樹枝與相鄰樹枝節點的群動性突顯行為(Emergent Behaviors)的動態表現,並且著重在將仿生概念與外部使用者觸覺互動的資訊表現,以此發展融合性的互動情境。

該創作將演算法自主調適性的動態過程,視覺化表現,模仿含羞草(Mimosa Plant)動態細胞間的反應行為。通過將碎形樹(Fractal Tree)數據結構的複雜性與單元自動機(Cellular Automata)的網格計算(Grid Computations)機制相結合,以人為的設計方法將含羞草生物性的群體葉片運動機制,創造出自然世界不存在樹狀結構上的樹狀連鎖動態反應。這樣的互動體驗(Interaction Design)是透過觸摸屏幕,提供觀者以手指輕觸葉片,來啟動一系列的細胞運動反應機制。這件作品以系統運算的機制設計為基礎,運用衍生式規則和參數設計來探索非傳統的視覺圖像表現。從對生物形態的觀察和模仿,創作出模擬和再現植物的外形和生長行為的演算法,作為人工生命藝術 (Artificial Life Art) 的一種實踐。從遞迴(Recursion)、碎形樹(Fractal Tree)、L-system的運算結構和機制設計中,發展出仿擬生物的生長型態和視覺紋理,創建出與參觀者互動的機制。通過結合演算法的規則機制和參觀者的互動和資訊擷取,創造出能夠即時產生數據驅動藝術的視覺圖像的表現。
