here a try with the pst-solides-3d, however i do not get the MATHMODE 
for text on start...

\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-solides3d}
\begin{document}
\begin{pspicture}(-4,-1.5)(4,1.5)
\psset{solidmemory}
\psset{lightsrc=10 0 10,viewpoint=30 30 30 rtp2xyz,Decran=50}
\axesIIID(0,0,0)(2,2,2)
\psPolygonIIID[linecolor=black,
fillstyle=solid,fillcolor=lightgray,
linewidth=0.5pt](1,1,0)(-1,1,0)(0,0,1)(1,1,0)
\psSolid[object=plan,
definition=normalpoint,
args={0 0.5 0.5 [0 1 1 180]},
name=MyPlane,
action=none]
\psProjection[
object=texte,
fontsize=8,
linecolor=red,
pos=bc,
plan=MyPlane,
text={y+z=1},
](0,0)%
\composeSolid
\end{pspicture}
\end{document}


Hope this helps.

Regards,

Juergen
