最后一条curve的终点就是第一条curve的起点 知道基本规则之后,我们可以进行渲染，这里拿canvas里渲染为例子: Fill模式: function renderShapes(context, curves , color){ context.beginPath(); context.fillStyle = color||'black'; context.moveTo(curves[ 0][0], curves[0][1]); curves.forEach(function(points){ context.bezierCurveTo(points[2], points ){ renderShapes(context,curves,"#006DF0") }) Stroke模式: function renderCurve(context, points, color ){ curves.forEach(function (curve) { renderCurve(context, curve, "#006DF0") }) }) 当然你也可以把
