TikZ - 剪辑和手绘类似区域

Question

我想画一些这样的东西。

我的问题只是知道如何定义不同的区域而不是进行装饰。

如果您只需要椭圆的部分填充，可以尝试我的方法。

\documentclass[border=5pt]{standalone}

\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepgfplotslibrary{fillbetween}

\begin{document}
    \begin{tikzpicture}
        \begin{scope}
            \clip (0,0) ellipse [x radius=2, y radius=1];
            \path[name path=a] (0,0) ellipse [x radius=2, y radius=1];
            \path[name path=b] (0,-1) to[out=135, in=315] (0,1);
            
            \draw [fill=cyan!50!white] (0,0) ellipse [x radius=2, y radius=1];
            
            \draw [fill=green!50!black,
            intersection segments={
                    of=a and b,
                    sequence={L2--R2}
                }
            ];
            
            \begin{scope}
                \clip (0,-1) circle[radius=1];
                \draw (0,-1) circle[radius=1];
            \end{scope}
        
        \end{scope}
        
    \end{tikzpicture}   
\end{document}

对于模式，你可以使用patterns或做一些循环，foreach例如

\foreach\i in {-10,-9.75,...,10}{%
    \draw[orange] (\i,0) --++ (45:4);
}

在clip和scope环境中

我尝试了一下之前的例子，现在它应该可以满足您的需求。
