使用 tikz 进行中心复合设计

我正在尝试使用 tikz 制作以下中心复合设计。

期望结果

我的 MWE 输出为：

代码

\documentclass[tikz]{standalone}
\usepackage{tikz}      
\usetikzlibrary{calc}  

\begin{document}
    \begin{tikzpicture}[scale=4,fill opacity=0.4,thick,
                        line cap=round,line join=round]
    %% Define coordinate labels.
    % t(op) and b(ottom) layers
    \path \foreach \layer/\direction in {b/{0,0,0},t/{0,1,0}} {
        (\direction)
        \foreach \point/\label in {{0,0,0}/ll,{1,0,0}/lr,{1,0,-1}/ur,{0,0,-1}/ul} {
            +(\point) coordinate (\layer\label)
        }
        ($(\layer ll)!0.5!(\layer ur)$) coordinate (\layer md)
    };

    % Put text next to the labels as requested.
    % Funilly enough we need to set fill opacity to 1.

    % Draw left cube.
    \fill (0, 0,-1) circle (0.5pt);

    \foreach \direction in {(0,0,1),(0,1,0),(1,0,0)} {
        \draw[dashed,black] (bul) -- + \direction;
    }
    \draw (bll) -- (blr) -- (tlr) -- (tll) -- cycle;
    \draw (blr) -- (bur) -- (tur) -- (tlr) -- cycle;
    \draw (tll) -- (tlr) -- (tur) -- (tul) -- cycle;
    \foreach \point in {bul, bll, blr, bur, tll, tlr, tul, tur} {
        \fill[fill opacity=1] (\point) circle (0.75pt);
    }

\draw (1.5, 0, -1) -- (0, 0,-2);

    \end{tikzpicture}

我在绘制顶点时遇到了困难。如能得到任何帮助我将不胜感激。提前致谢。

以下是一些可以让你开始展示轴的内容。其中一个问题是z轴与边缘重叠：

\documentclass{article}
\usepackage{tikz}

    \path \foreach \layer/\direction in {b/{0,0,0},t/{0,1.5,0}} {
        (\direction)

        }

    };

    % Put text next to the labels as requested.
    % Funnily enough we need to set fill opacity to 1.

    % Draw left cube.
    \fill (0, 0,-1.5) circle (0.5pt);

    \foreach \direction in {(0,0,1.5),(0,1.5,0),(1.5,0,0)} {

            %node [below] {\point}% <----- uncomment for debugging
