Zeichnen eines Kreuzes mit nur einem Quadranten

Question

Um dieses Kreuz zu zeichnen,

Ich habe den folgenden sehr langen und zeitaufwändigen Code verwendet.

Ich dachte daran, diesen Code zu vereinfachen, indem ich nur einen Quadranten zeichne und das Speicherfeld verwende, um ihn zu wiederholen. Aber ich konnte nicht herausfinden, wie ich das genau machen und das Zeichnen der unnötigen Linien im Inneren vermeiden konnte.

Answer 1

Code von meinem Freund.

% Bui Quy
\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}[line join=round,line cap=round]
\def\edge{
(.5,.5)
to[out=90,in=-150] ++(1,2)
to[out=120,in=0] ++(-1,.5)
to[out=90,in=-30] ++(-.5,1)
to[out=-150,in=90] ++(-.5,-1)
to[out=180,in=60] ++(-1,-.5)
to[out=-30,in=90] ++(1,-2)
}

% Schrodinger's cat suggested this better code
\draw[fill=lime] (.5,.5) 
foreach \i in {0,90,180,270} {[rotate=\i]--\edge}
--cycle;
\end{tikzpicture}
\end{document}

Answer 2

hier ist mein Vorschlag, ich habe Ihre Zeichnung geändert und die Knoten gelöscht und durch eine Zeichnung ersetzt, die es ermöglicht, die Markierungsänderungen und Transformationen zu verwenden

\documentclass{article}

\usepackage{verbatim}
\usepackage{tikz}
\begin{document}



\newcommand{\crossq}{

\def\coef{1}
\path[blue,thick,fill=red!30] (0,0) coordinate(O)
-- (180:0.6) coordinate(oual)
to [out=90,in=-10] coordinate[pos=0.23] (a1)++(-1,2.1)coordinate(a2)
to[out=50,in=180] ++(1,0.3)
to[out=90,in=-150] ++ (0.6,1)
-- cycle;

\draw[blue,thick] (a1)
to [out=90,in=-10] (a2)
to[out=50,in=180] ++(1,0.3)
to[out=90,in=-150] ++ (0.6,1);

\path[purple,thick,fill=red!30] (0,0) coordinate(O)
-- (0:0.6) coordinate(oual)
to [out=90,in=190] coordinate[pos=0.23] (b1)++(1,2.1)coordinate(b2)
to[out=130,in=0] ++(-1,0.3)
to[out=90,in=-30] ++ (-0.6,1)
-- cycle
;

\draw[purple,thick,fill=red!30] (b1)
to [out=90,in=190] (b2)
to[out=130,in=0] ++(-1,0.3)
to[out=90,in=-30] ++ (-0.6,1)
;

}



\begin{tikzpicture}
\begin{scope}
\crossq



\end{scope}
\begin{scope}[rotate=90]
\crossq
\end{scope}
\begin{scope}[rotate=-90]
\crossq
\end{scope}
\begin{scope}[rotate=180]
\crossq
\end{scope}

\end{tikzpicture}

\end{document}
