隐藏部分曲线、路径或边缘

Question

我希望在双边经过 fl 和 hc 之间的所有地方时隐藏它（而不仅仅是在交点处）。我需要一个解决方案没有强迫我手动计算（f）和（h）处的斜率。

理想情况下，我希望能够“关闭”给定曲线两点之间的任何曲线绘制。

\documentclass{standalone}
\usepackage{tikz,pgf}
\usetikzlibrary{intersections}


\begin{document}
\begin{tikzpicture} [every node/.style={draw,circle}]

\node (b) at (0,5){b};
\node (c) at (8,5){c};


\node (f) at (0,2){f};
\node (h) at (1,0){h};
\node (i) at (7,0){i};
\node (l) at (6,5){l};





\draw (f) edge [name path=pf, line width=2pt, in=-90, out=0] (l);
\draw (b) edge [ name path=pb, line width=2pt, in=180, out=-90] (i);
\draw (h) edge [name path=ph, line width=2pt, in=-90, out=0]  (c);

\node [name intersections={of=pb and ph, by={e}}, fill=white] at (e) {e};
\node [name intersections={of=pb and pf, by={d}}, fill=white] at (d) {d};



\end{tikzpicture}

\end{document}

我发现了一个肮脏的解决方案，在节点之间绘制一个椭圆d然后e重新绘制它们。

\documentclass[margin=5mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{intersections,shapes,fit,calc}

\begin{document}
\begin{tikzpicture} [every node/.style={draw,circle}]

\node (b) at (0,5){b};
\node (c) at (8,5){c};
\node (f) at (0,2){f};
\node (h) at (1,0){h};
\node (i) at (7,0){i};
\node (l) at (6,5){l};

\draw (f) edge [name path=pf, line width=2pt, in=-90, out=0] (l);
\draw (b) edge [name path=pb, line width=2pt, in=180, out=-90] (i);
\draw (h) edge [name path=ph, line width=2pt, in=-90, out=0]  (c);

\node [name path=circe,name intersections={of=pb and ph, by={e}},fill=white] at (e) {e};
\node [name path=circd,name intersections={of=pb and pf, by={d}},fill=white] at (d) {d};
\path [name intersections={of=circd and pb, by={d1,d2}}];
\path [name intersections={of=circe and pb, by={ee}}];

\path let
         \p1 = ($(d2.north east)-(ee.south west)$),
         \n1 = {veclen(\p1)}
         in
         (d2.south) -- (ee.north) 
         node[white,midway, sloped, draw, ellipse,fill=white, 
              minimum width=\n1, minimum height=\n1/4] {};

\node [name path=circe,name intersections={of=pb and ph, by={e}}] at (e) {e};
\node [name path=circd,name intersections={of=pb and pf, by={d}}] at (d) {d};

\end{tikzpicture}

\end{document}
