将 LaTeX 投影到平面上而不仅仅是将文本投影到平面上 pst-solides3d

Question

我可以投影文本

\psSolid[oject=text, text = zyz]

但想把 LaTeX 中的内容$\alpha$作为文本。\psProjection逐字打印：$\alpha$。

是否可以强制使用 LaTeX？

以下是来自的一个稍微修改过的例子pst-solides3d 文档：

\documentclass{article}
\usepackage{pst-solides3d}

\begin{document}

\psset{viewpoint=50 20 30 rtp2xyz,Decran=50}
\begin{pspicture}(-4,-4)(4,5)
  \psset{unit=0.5}
  \psset{solidmemory}
  \psSolid[object=cube,a=8,action=draw,name=A,linecolor=red]%
  \psset{fontsize=100}
  \psSolid[object=plan,action=none,definition=solidface,args=A 0,name=P0]
  \psProjection[object=texte,linecolor=red,text=$\alpha$,plan=P0]%
  \psSolid[object=plan,action=none,definition=solidface,args=A 1,name=P1]
  \psProjection[object=texte,linecolor=red,text=$\beta$,plan=P1]%
  \psSolid[object=plan,action=none,definition=solidface,args=A 4,name=P4]
  \psProjection[object=texte,linecolor=red,text=$\epsilon$,plan=P4]%
  \axesIIID(4,4,4)(6,6,6)
\end{pspicture}

\end{document}

\documentclass[pstricks]{standalone}
\usepackage{pst-solides3d}
\begin{document}

\psset{viewpoint=50 20 30 rtp2xyz,Decran=50}

    \psset{unit=0.5}
    \psSolid[object=cube,a=8,action=draw,name=A,linecolor=red]%
    \psset{fontsize=150,PSfont=Symbol}%%%%%%%%%%%%%%%%%%%%%
    \psSolid[object=plan,action=none,definition=solidface,args=A 0,name=P0]
