In Polypaths, plants don’t grow blindly along predefined routes. They respond to flow and tension—like a traditional East Asian landscape painter who studies the entire scene’s qi (energy flow) and shi (momentum) before making the first brushstroke.

Behind the scenes, the system runs an invisible pre-process: it analyzes whether the drawn path contains a strong downward pull or elongated strokes. If the trajectory feels heavy and sinking, it activates one mode; if the lines expand outward with force and direction, it shifts to another.
This echoes a fundamental principle in classical Chinese painting—not deciding what to draw, but sensing how the energy moves through the composition. It’s about responding to flow, not filling in shapes.

In “Forest Mode,” plants grow taller, denser, and more expressive—like dark ink strokes shaping a mountain. In “Vine Mode,” the main plant is intentionally left bare, its structure serving as scaffolding for vines that will later coil and complete the image. This is the philosophy of using emptiness to reveal form—a central lesson in East Asian aesthetics.

Nothing grows randomly here. Every gesture has intention, breath, and rhythm. And all of it emerges as a programmatic response to the sensed energy in the path.
This is what I strive for—not machines drawing plants, but plants that draw like painters. They read the momentum first, then let form follow intention.

第六篇 從構圖邏輯到植徑哲學

在《植徑集》裡，植物不只是順著路徑盲目生長。它們會「觀勢而動」——像古代山水畫家一樣，在落筆之前，先閱讀整體的「氣」與「勢」，再決定如何運筆。這個系統的秘密藏在一段你看不到的前置程式：它會統計路徑中是否出現了大量「長線」或「向下」的動態。如果太多筆觸往下垂，就會啟動模式；如果筆勢開展、張力十足，就會進入模式。

這其實就是東方山水畫裡的基本概念——不是先決定要畫什麼，而是看「整體氣場」如何流動。是「順勢寫景」，不是「強行填圖」。森林模式裡，植物會長得更高，筆觸更厚重，像用重墨皴擦山形；藤蔓模式裡，主植物會刻意被留白，只留下骨架，為後續纏繞的藤蔓預留空間。這正是「以虛托實」的佈局哲學，也是東方美學中最重要的一課。

畫面皆不是亂長的，而是有取捨、有呼吸。而這一切，來自程式「讀懂了氣勢」之後，做出的回應。這就是我想做的：不是機器畫植物，而是讓植物像一位書畫家讀勢，而後下筆，成其形，達其意。
