[pstricks] \pstHomO

[Juergen Gilg]

Dear Dominique,

many thanks as well to you. Now i found that in the PSTricksbook. 
Overread it.

Here my progress. However not really correct, but soon reach the aim.

\documentclass{article}
\usepackage{multido}
\usepackage{pstricks,pst-eucl,pstricks-add}
\begin{document}
\begin{center}
\begin{pspicture}(-3,-2.5)(2,2)
\pstGeonode[PosAngle={0,-45},PointName=none,PointSymbol=none](.5,1){S}(-1.5,-1.2){A}(.5,-.8){B}
\psset{linecolor=black, nodesep=-.4}
\multido{\n=0+0.2, \i=2+1, \ia=1+1}{12}{
\pstHomO[HomCoef=\n, 
PosAngle=-45,PointName=none,PointSymbol=none]{S}{A,B}[C\i,D\i]
\ncline[nodesep=-.5,linewidth=0.7\pslinewidth]{C\i}{D\i}
\ncline[linewidth=0pt]{C\i}{C\ia}\ncput[ref=r]{\small$y\,\,$}
\ncline[linewidth=0pt]{D\i}{D\ia}\ncput[ref=l]{\small$\,\,x$}
}
\psset{linecolor=black, XnodesepA=-1.5, YnodesepA=-3.7}
\pstLineAB{A}{S}
\pstLineAB{B}{S}
\end{pspicture}
\end{center}
\end{document}

Regards,

Juergen
