我正在尝试将两个 tikz 图合并在一起，但遇到了一些问题。我有第一个图，其中包含 3d 版本，然后我有第二个图像，我想将其映射到第一个图像的灰色平面部分。我真的很感激有人能帮我完成这件事。谢谢。
\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz-3dplot}
\usetikzlibrary{arrows.meta,bending}
\begin{document}
\tdplotsetmaincoords{70}{20}

declare function={pX=2;}]
\begin{scope}[canvas is yz plane at x=0]
\draw (-pX,-pX) coordinate (bl1) -- (pX,-pX) coordinate (br1)
-- (pX,pX) coordinate (tr1) -- (-pX,pX) coordinate (tl1) -- cycle;
\draw[stealth-stealth] (0,pX) node[below left]{$x_2$}
-- (0,0) -- (pX,0) node[below left]{$x_1$};

\draw[-{Latex[bend]}] (0,-1) arc(-90:290:1);
\draw[-{Latex[bend]}] (0,0) arc(-90:380:1);
\end{scope}
\foreach \X in {bl,tl,br,tr}

第二张图片
\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz-3dplot}
\usetikzlibrary{arrows.meta,bending}
\begin{document}
\begin{tikzpicture}
\begin{scope}
\clip (0,0) rectangle (4,3);
\foreach \X in {-2,-1.6,...,2}
{\draw (0,\X) parabola ++(5,2);}
\end{scope}
\draw[-stealth] (-1,0) -- (5,0) node[below right]{$x_3$};
\draw[-stealth] (0,-0.5) node[above left]{$0$} -- (0,3)
node[right=2em,yshift=-1em]{$\theta(x_3)$};
\draw[-stealth] (4,-0.5) node[above left]{$L$} -- (4,3) node[below right]{$x_1$};

切换到 xy 平面，您可以重复使用第二张图像中的代码：
\documentclass[tikz,border=3.14mm]{standalone}
\usepackage{tikz-3dplot}
\usetikzlibrary{arrows.meta,bending}
\begin{document}
\tdplotsetmaincoords{70}{20}
\begin{tikzpicture}[tdplot_main_coords,
declare function={pX=2;}]
\begin{scope}[canvas is yz plane at x=0]
\draw (-pX,-pX) coordinate (bl1) -- (pX,-pX) coordinate (br1)
-- (pX,pX) coordinate (tr1) -- (-pX,pX) coordinate (tl1) -- cycle;
\draw[stealth-stealth] (0,pX) node[below left]{$x_2$}
-- (0,0) -- (pX,0) node[below left]{$x_1$};
\pgflowlevelsynccm
\draw[-{Latex[bend]}] (2,0) arc(0:380:1);
\draw[-{Latex[bend]}] (0,-1) arc(-90:290:1);
\draw[-{Latex[bend]}] (0,0) arc(-90:380:1);
\end{scope}
\foreach \X in {bl,tl,br,tr}
{\draw[-latex] (\X1) -- ++ (1,0,0);}
%
\draw (0,0,0) -- (4,0,0);
% plane
\fill[gray,fill opacity=0.3] (-1,-4,0) -- (7,-4,0) --
(7,4,0) -- (-1,4,0) -- cycle;
\begin{scope}[canvas is yz plane at x=4]
\draw (-pX,-pX) coordinate (bl2) -- (pX,-pX) coordinate (br2)
-- (pX,pX) coordinate (tr2) -- (-pX,pX) coordinate (tl2) -- cycle;
\draw[stealth-stealth] (0,pX) -- (0,0) -- (pX,0);
\pgflowlevelsynccm
\draw[-{Latex[bend]}] (1,0) arc(0:380:0.25);
\draw[-{Latex[bend]}] (0,-0.25) arc(-90:290:0.25);
\draw[-{Latex[bend]}] (0,0.25) arc(-90:380:0.25);
\end{scope}
\draw[-latex] (4,0,0) -- (6,0,0) node[below left]{$x_3$};
\foreach \X in {bl,tl,br,tr}
{\draw[-latex] (\X2) -- ++ (1,0,0);}
\begin{scope}[canvas is xy plane at z=0]
\begin{scope}
\clip (0,0) rectangle (4,3);
\foreach \X in {-2,-1.6,...,2}
{\draw (0,\X) parabola ++(5,2);}
\end{scope}
% \draw[-stealth] (-1,0) -- (5,0) node[below right]{$x_3$};
% \draw[-stealth] (0,-0.5) node[above left]{$0$} -- (0,3)
% node[right=2em,yshift=-1em]{$\theta(x_3)$};
% \draw[-stealth] (4,-0.5) node[above left]{$L$} -- (4,3) node[below right]{$x_1$};
\end{scope}
\end{tikzpicture}
\end{document}
