如何使用「生成三龙曲线」?How do I use the Generate Terdragon Curve tool?
在「生成三龙曲线」中,按需设置「宽度」、「高度」、「边距」、「线宽」、「迭代次数」等选项,然后点击「绘制」、「下载 PNG」按钮即可。In the Generate Terdragon Curve: Set "Width", "Height", "Padding", "Line width", "Iterations", then click "Draw", "Download PNG".
三龙曲线的规则是什么?What is the terdragon rule?
L 系统 F → F+F−F,转角 120°,起始 F。每次迭代线段数乘 3,第 n 次共 3ⁿ 段;曲线会在顶点处与自己相接,但不会重复走同一条边。三条三龙曲线绕一点可以铺满平面。The L-system F → F+F−F with 120° turns, starting from F. Each iteration triples the segment count, so iteration n has 3ⁿ segments; the curve touches itself at vertices but never retraces an edge. Three terdragons around a point tile the plane.

那一页画的就是同一条三龙曲线(120° 版本的龙曲线);本页最多 12 次迭代。That page draws the same terdragon (the 120° version of the dragon curve); this page goes up to 12 iterations.
有哪些选项可以调整?What options can I adjust?
「生成三龙曲线」的设置:「宽度」默认 512,范围 64–2048;「高度」默认 512,范围 64–2048;「边距」默认 20,范围 0–256;「线宽」默认 2,范围 0.5–40;「迭代次数」默认 8,范围 1–12;「背景」默认 #ffffff;「线条」默认 #1e3a8a。每次生成结果都按当前设置处理。Settings in the Generate Terdragon Curve — "Width" default 512, range 64–2048; "Height" default 512, range 64–2048; "Padding" default 20, range 0–256; "Line width" default 2, range 0.5–40; "Iterations" default 8, range 1–12; "Background" default #ffffff; "Line" default #1e3a8a. The result always uses the current settings.
