# [pstricks] two questions about pstrick and pst-3dplot

hi dingfang zeng,

could you provide minimal examples?

I tried out the following:

\documentclass{article}
\usepackage{pstricks,pst-3dplot}

\psset{Alpha=0,Beta=90,unit=0.5cm}
\begin{pspicture}[](-3,-1.5)(3,1.5)
\def\phii{1}\def\phiii{2} \pstThreeDLine(\phii,\phii,\phiii)%this
compiles ok with my system

%\pstThreeDLine(! 2 2 2 2 add)%nope
%\psline(\phii\space 2 2)%no ----> hint from other list-member
\end{pspicture}\end{document}

so it seems to be that in the 3D-case you cannot make computations

in the 2D-case you can make computations, but not mixed up together

I'm not sure if there is any possibility to make computations (which
are carried out by postscript) together with definitions made in the
LaTeX-code, even in 2D-geometry.

for your other problem I have no time to study it at the moment,
sorry. but for sure herbert will look into it soon.
