立方体内的角立方体

Question

我想使用 tikz 在立方体内绘制一个立方体，以便内部立方体是一个内角，就像下面的图画一样。 我希望内部立方体有阴影，并且其大小可以调整，但通常较小。此外，我希望留出空间来标记所有轴，这是一张概念图，因此不需要刻度线。

运行xelatex：

\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}
\psset{lightsrc=viewpoint,viewpoint=50 60 25 rtp2xyz,Decran=50}
\begin{pspicture}[showgrid=false](-3,-3)(3,3)
\psSolid[object=cube,a=4,action=draw]
\psSolid[object=cube,a=1,fillcolor=yellow,action=draw**](-1.5,1.5,-1.5)
\end{pspicture}

\end{document}
