有人能建议一种使用 TikZ 绘制随机浮游生物群落的方法吗？类似于
我知道可以保存图像然后将其加载到 LaTeX 中，但我希望有一种单独绘制它们的方法。
答案1
或者，您可以使用 pgf 3.0.0 和pic语法。
\documentclass[border=0.12cm,tikz]{standalone}
\usetikzlibrary{decorations.pathmorphing}
\begin{document}
\tikzset{%
plankton 1/.pic={
\fill [green!20!brown]
\foreach \i in {1,2,3}{
[rotate=\i*120] (0,1.125) ellipse [x radius=.5, y radius=1]
};
\clip [preaction={fill=blue!60}]
circle [radius=1.125];
\foreach \i in {1,...,50}
\fill [blue!70] (rnd*360:rnd*1.125)
circle [radius=0.125];
},
plankton 2/.pic={
\draw [thick, line cap=round, black!80]
(-0.125,2) to [bend right] ++(120:1.125)
( 0.125,2) to [bend left] ++(60:1.125)
(-0.125,0) to [bend left] ++(240:1)
( 0.125,0) to [bend right] ++(300:1);
\foreach \i [evaluate={\l=2+\i/4;}] in {1,...,4}
\draw [black!80]
(-0.125,\i/8) to [bend right, out=270, in=270, looseness=\l] (0,1+\i/4)
(-0.125,\i/8) to [bend right, out=90, in=90, looseness=\l] (0,1+\i/4);
\foreach \i [evaluate={\j=mod(\i,2)*10+10;}] in {1,...,8}
\fill [green!\j!brown] (0,\i/4)
ellipse [x radius=(4+\i)/16, y radius=0.25];
},
plankton 3/.pic={
\fill [green!20!brown]
ellipse [x radius=0.25, y radius=1];
\fill [green!10!brown]
ellipse [x radius=0.25, y radius=0.5];
\draw [thick, black, line cap=round]
(-0.5,-2) to [bend right, looseness=.5] (-0.5,2)
( 0.5,-2) to [bend left, looseness=.5] ( 0.5,2);
}
}
\begin{tikzpicture}[x=5pt,y=5pt]
\fill [blue!20]
(0,0) -- (55,0) -- (55,10)
decorate [decoration={snake, segment length=1cm, amplitude=.125cm}]
{ -- (0,10) } -- cycle;
\foreach \i [evaluate={\p=int(random(1,3))}] in {1,...,10}
\path (\i*5, rnd*5+2.5) pic [rotate=rnd*360] {plankton \p};
\end{tikzpicture}
\end{document}

嗯，这是A浮游生物。有人想吃蟹黄堡吗？
