5 Patterns · 5 種圖案
Core / Halo share the same weave function, differentiated by ratio (φ). Cobweb uses 3–4 point interlaced weaving. Ascend / Descend are fractal structures that double or halve node counts per layer.
Core/Halo 以比例區分視覺密度；Cobweb 交錯編織；Ascend/Descend 碎形結構。
Golden Ratio · 黃金比例
Default shrink ratio φ = 1.618 ensures natural geometric scaling across layers. Smaller values create denser patterns; larger values produce looser, airy structures.
較小的比例讓圖案更緊密，較大的值讓層次更寬鬆。
Thread Length · 線長估算
Enter the ring diameter and the tool calculates total thread path length — useful when buying materials. Formula: Σ∥P[i]–P[i-1]∥ × (R / r).
輸入外框直徑，自動估算購買線材所需長度。
