[pstricks] pst-3dplot

[Patrice MEGRET]

Dear Herbert,

I have a small problem with pst-3dplot.

\documentclass{report}
\usepackage{pstricks}
\usepackage{pst-3dplot}


\begin{document}

\begin{pspicture}(-3,-3)(3,3)
\psset{Alpha=55,Beta=30}
\pstThreeDCoor[linecolor=red,xMax=4,yMax=4.5,zMax=3.5]
\parametricplotThreeD[xPlotpoints=100,yPlotpoints=20](-90,90)(0,180){%
1.5 t cos u sin mul mul %
4 t sin u sin mul mul %
3 u cos mul}
\parametricplotThreeD[yPlotpoints=20,xPlotpoints=100](0,180)(-90,90){%
1.5 u cos t sin mul mul %
4 u sin t sin mul mul %
3 t cos mul}
\end{pspicture}


\begin{pspicture}(-3,-3)(3,3)
\psset{Alpha=90,Beta=30}
%\pstThreeDCoor[linecolor=red,xMax=4,yMax=4.5,zMax=3.5]
\parametricplotThreeD[xPlotpoints=100,yPlotpoints=20](-90,90)(0,180){%
1.5 t cos u sin mul mul %
4 t sin u sin mul mul %
3 u cos mul}
\parametricplotThreeD[yPlotpoints=20,xPlotpoints=100](0,180)(-90,90){%
1.5 u cos t sin mul mul %
4 u sin t sin mul mul %
3 t cos mul}
\end{pspicture}

\end{document}


When I used  "\pstThreeDCoor[linecolor=red,xMax=4,yMax=4.5,zMax=3.5]" the first graph, the second is wrong if "\pstThreeDCoor[linecolor=red,xMax=4,yMax=4.5,zMax=3.5]" is commented out.
If there are no \pstThreeDcoor at all, it is also correct.
It seems that Alpha and Beta are not set properly.
