想要在 TeX 中制作以下矩形框。可以吗?
答案1
另一个模板。您可以使用旋转来ellipse
代替circle
以获得最佳可视化效果。
\documentclass{article}
\usepackage{tikz}
\usepackage{3dplot}
\begin{document}
\tdplotsetmaincoords{60}{60}
\begin{tikzpicture}
[tdplot_main_coords,
grid/.style={very thin,gray},
axis/.style={->,blue,thick},
cube/.style={opacity=.5,very thick,fill=red}]
%draw the axes
\draw[axis] (0,0,0) -- (4,0,0) node[anchor=west]{$x$};
\draw[axis] (0,0,0) -- (0,10,0) node[anchor=west]{$y$};
\draw[axis] (0,0,0) -- (0,0,3) node[anchor=west]{$z$};
%draw the bottom of the cube
\draw[cube] (0,0,0) -- (0,7,0) -- (3,7,0) -- (3,0,0) -- cycle;
%draw the back-right of the cube
\draw[cube] (0,0,0) -- (0,7,0) -- (0,7,2) -- (0,0,2) -- cycle;
%draw the back-left of the cube
\draw[cube] (0,0,0) -- (3,0,0) -- (3,0,2) -- (0,0,2) -- cycle;
%draw the front-right of the cube
\draw[cube,yellow] (3,0,0) -- (3,7,0) -- (3,7,2) -- (3,0,2) -- cycle;
%draw the front-left of the cube
\draw[cube] (0,7,0) -- (3,7,0) -- (3,7,2) -- (0,7,2) -- cycle;
%draw the top of the cube
\draw[cube,blue] (0,0,2) -- (0,7,2) -- (3,7,2) -- (3,0,2) -- cycle;
%draw dashed rect
\draw[cube,dashed] (1.5,0,0) -- (1.5,0,2) -- (1.5,7,2) -- (1.5,7,0) -- cycle;
%draw circles
\node[circle,draw,thick,minimum size=0.5cm] (fc) at (3,3.5,1) {};
\node[circle,draw,thick,dashed,minimum size=0.5cm] (fcd) at (1.5,3.5,1) {};
%draw circle lines
\draw [thick] (fc.210)-- (fcd.210)--++(180:1) coordinate (A);
\draw [thick] (fc.60)-- (fcd.60)--++(180:1) coordinate (B);
\draw [thick] (B) to[bend right=60] (A);
\end{tikzpicture}
\end{document}

仅用于 PSTricks 模板。我将其设置为 wiki 答案,请随意编辑。
\documentclass[pstricks,border=12pt,12pt]{standalone}
\usepackage{pst-solides3d}
\begin{document}
\begin{pspicture}[viewpoint=30 -10 10 rtp2xyz,Decran=30,lightsrc=viewpoint](-2,-2)(8,6)
\psSolid[object=cylindrecreux,h=2,r=1,fillcolor=cyan,ngrid=20 20,grid=false,RotY=90](0,2.5,1.5)
\psSolid[object=prisme,action=draw,base=0 0 3 0 3 5 0 5,h=3]
\axesIIID[labelsep=.5](0,5,0)(6,7,4)
\end{pspicture}
\end{document}
