图表的阴影部分

尽管标题看起来与此类似问题，我们找不到任何与我们想要的答案相关的内容。我们想用茅草遮蔽图形的一部分（具有顶点和边的图形），就像这张照片中一样，茅草遮荫我们使用 Tkiz 绘制了如下图表，Tkiz 图。现在我们想对图表的各个部分（由方形瓷砖形状组成的区域）进行阴影处理，有时阴影会重叠，因此如果我们可以为茅草选择不同的角度或不同的茅草密度，那就太好了。提前感谢指点。

以下是我们目前的情况，

像这样？

在此处输入图片描述

MWE 是：

正如您所看到的，代码被大量重写。它不再绘制线条，而是使用节点，这些节点在水平方向上绘制，完成后旋转 45 度。

用于阴影patterns.metta（如@SebGlaw 在其评论中所建议的那样）。为此过程定义了特殊样式，其中定义了线条的角度、线条粗细和它们之间的距离。

对使用包装绘制的拉括号给予了额外的注意calligraphy。
