\psset{xunit=0.4cm,yunit=0.4cm,xMin=0.01,xMax=10,yMin=0.01,yMax=10,zMin=0.01,zMax=6.81,Alpha=135,Beta=120}
\begin{pspicture}(0,0)(10,10)
\pstThreeDCoor
\pstThreeDBox(0,0,0)(10,0,0)(0,10,0)(0,0,10)
\psplotThreeD[linecolor=blue,plotstyle=line,drawStyle=xyLines](0.01,10)(0.01,10){x 
1 3 div exp y 1 2 div exp mul}
\end{pspicture}

\psplotThreeD(xMin,xMax)(yMin,yMax)
