如何标记以下八面体的顶点？ 
\begin{tikzpicture}[z={(-.3cm,-.2cm)}, % direction z gets projected to; can also change x,y
                                       % use cm to specify non-transformed coordinates
                    line join=round, line cap=round % makes the corners look nicer
                   ]
  \draw (0,1,0) -- (-1,0,0) -- (0,-1,0) -- (1,0,0) -- (0,1,0) -- (0,0,1) -- (0,-1,0) (1,0,0) -- (0,0,1) -- (-1,0,0);
  \draw[dashed] (0,1,0) -- (0,0,-1) -- (0,-1,0) (1,0,0) -- (0,0,-1) -- (-1,0,0);
\end{tikzpicture}

像这样：

在此处输入图片描述

这非常简单，只需添加node到八面体顶点即可。我没有费心选择顶点的名称（标签）：

\documentclass[tikz, margin=3mm]{standalone}

\begin{document}
\begin{tikzpicture}[z={(-.3cm,-.2cm)}, % direction z gets projected to; can also change x,y
                                       % use cm to specify non-transformed coordinates
                    line join=round, line cap=round, % makes the corners look nicer
                    every node/.style = {inner sep=1pt, font=\scriptsize}
                   ]
  \draw ( 0,1,0) node[above] {A} --
        (-1,0,0) node [left] {B} --
        (0,-1,0) node[below] {C} --
        ( 1,0,0) node[right] {D} --
        ( 0,1,0) --
        ( 0,0,1) node[below left] {E} --
        (0,-1,0) (1,0,0) -- (0,0,1) -- (-1,0,0);
  \draw[dashed] (0,1,0) -- (0,0,-1) -- (0,-1,0) (1,0,0) -- (0,0,-1) -- (-1,0,0);
\end{tikzpicture}
\end{document}
