我正在尝试为顶点 1-2-3 的各种三角形进行着色。
以下是我目前所掌握的信息：
\begin{center}
\begin{tikzpicture}[scale=4] %color=red
\SetVertexLabel
\tikzstyle{every node}=[thick,draw, shape=circle,scale=.5]; %fill=black,
\path (0:0cm) node (1) {1};
\path (-60:1.7cm) node (2) {2};
\path (240:1.7cm) node (3) {3};
\path (240:1cm) node (4) {3};
\path (240:.5cm) node (5) {3};
\path (240:1.4cm) node (6) {1};
\path (-60:.75cm) node (7) {2};
\path (-60:1.2cm) node (8) {1};

\path (260:1.2cm) node (10) {1};
\path (280:.5cm) node (11) {2};
\path (279:1.1cm) node (12) {3};
\path (265:.8cm) node (13) {1};
\SetVertexLabel
\tikzstyle{every node}=[thick,draw, shape=circle,scale=.5,fill=red]

\path (295:1.35cm) node (27) {};
\path (287:1.4cm) node (28) {};

\draw[black,very thick] (1) -- (7)

\end{center}
输出如下：
我尝试了代码底部的 %commands，但到目前为止它们还没有起作用。有办法吗？
答案1
我使用background图层填充了一些三角形。为了获得更好的效果，我还在fill=white每个顶点上添加了图层。
原始解决方案的问题在于您没有得到一个封闭的区域来填充。语法(1)--(3)--... 在节点的边界上停止线条。您需要明确指向它们的中心：(1.center)--(3.center)--...
