- 怎样放箭？
在此先感谢您的帮助。
答案1
关于飞镖：
\documentclass{article}
\usepackage{tikz}
\begin{document}
\colorlet{gold}{orange!50!yellow}
\def\dart#1#2#3{ % 1 = tip position, 2 = rotation angle, 3 = dart color
\begin{scope}[rotate=#2]
\colorlet{dart color}{#3}
% tip
\fill[top color=black!30, bottom color=black!60, middle color=white]
(#1) ++(0,0) -- ++(1,0.04) -- ++(0,-0.04) -- cycle;
% golden mass
\fill[top color=gold, bottom color=gold!60!black, middle color=gold!20!white]
(#1) ++(0.99,0) to[out=90, in=180] ++(0.2, 0.2) -- ++(0.5, 0) -- ++(0, -0.4) -- ++(-0.5,0) to[out=180, in=-90] ++(-0.2,0.2) -- cycle;
% wings
\fill[top color=dart color!20!white, bottom color=dart color!10!black, middle color=dart color!70!white]
(#1) ++(4.5,0) to[out=60, in=150] ++(3.1,1) -- ++(-0.3,-1) -- cycle;
\fill[top color=dart color!20!black, bottom color=dart color]
(#1) ++(4.5,0) to[out=-60, in=-150] ++(3.1,-1) -- ++(-0.3,1) -- cycle;
% body
\fill[top color=dart color!20!white, bottom color=dart color!10!black, middle color=dart color]
(#1) ++(1.7,0.2) .. controls +(1,.2) and +(-4,.4) .. ++(6,-0.2) .. controls +(-4, -.4) and +(1,-.2) .. ++(-6, -0.2) -- cycle;
\end{scope}
}
\begin{tikzpicture} % Demo
\dart{0,0}{30}{yellow}
\dart{0,0}{-10}{red}
\dart{0,0}{10}{green!70!cyan}
\dart{0,0}{-25}{blue!50!cyan}

结果：
与靶心的整合：

结果：
更新：
通过使用画布变换改进了“透视”。还添加了一个棕色圆圈来伪造飞镖靶的一些深度：
代码中唯一的变化是在开头tikzpicture：
\begin{tikzpicture}
% Next scope and its options are not from the original code,
% but added here to better integrate with my darts
\begin{scope}[rotate=81,scale=0.14, transform canvas={xscale=0.6,xslant=-0.3}]
% These are the official dartboard dimensions as per BDO's regulations.
% The whole board's background.
\fill[brown!80!black] (-1,2) circle (225.5mm); % <-- Fake "depth"
\fill[black] (0, 0) circle (225.5mm);
% The remaining is unchanged...
更新 2
（最后一个，保证；-））
我认为通过改变数字使用的字体可以改善结果：
\node[number] at ({18 * (-\sector + .5)} : 197.75mm) {\sffamily\bfseries\large\label};
答案2
这只是一次尝试。我尝试让棋盘倾斜，并在棋盘上添加数字。我已经使用了该asymptote包。以下是代码：
\documentclass{standalone}
\usepackage{asymptote}
\begin{document}
\begin{asy}
size(3cm);
path p1 = ellipse((1,0), 9, 10);
path p2 = ellipse((1,0), 8.8, 9.8);
path p3 = ellipse((1,0), 7, 8);
draw(rotate(30)*p1);
fill(rotate(30)*p1, gray);
draw(rotate(30)*p2);
fill(rotate(30)*p2, white);
draw(rotate(30)*p3);
fill(rotate(30)*p2);
fill(rotate(30)*p3, white);
label("20", (1,9),white);
label("8", (9,1),white);
label("11", (1,-8.2),white);
label("2", (-7.5,0.8),white);
\end{asy}
\end{document}
生成的输出是：
现在，这似乎是一项非常繁琐的任务TikZ。然而，使用asymptote包75％是可能的（专家可以达到 100%，但需要相当大的耐心）。我已经展示了绘制倾斜椭圆和填充相交区域的方法。对所有椭圆和相应的标签执行相同的步骤。要获得箭头的 3d 效果，您可以这样做（如果您满意的话）：
相应的 MWE 是：
settings.render=16;
import three;
size(4cm,0);
draw(O--2X ^^ O--2Y ^^ O--2Z);
triple circleCenter = (Y+Z)/sqrt(2) +
X;
path3 mycircle =
circle(c=circleCenter, r=1,
normal=Y+Z);
draw(plane(O=sqrt(2)*Z, 2X, 2*unit(Y-Z)), gray + 0.1cyan);
draw(mycircle, blue);
draw(shift(circleCenter) * (O -- Y+Z), green, arrow=Arrow3());
（以上是asy您需要在\begin{asy}和中添加的代码\end{asy}）。
