[pstricks] \pstHomO

[Juergen Gilg]

Dear List,

i like to generate a figure like the attached PDF.

I made some thoughts of how to realize that and found the macro: \pstHomO

Some first steps i could realize. However the intersection points are 
labelled and i like to label the distances...

multido would be perfect to realize that, but i failed.

Anybody an idea?

Thanks in advance,

Juergen

\begin{document}
\begin{center}
\begin{pspicture}(-3,-2.5)(2,2)
\psframe[fillstyle=solid,fillcolor=lightgray](-3,-2.5)(2,2.5)
\pstGeonode[PosAngle={0,-45}](.5,1){S}(-1.5,-1.2){A}(.5,-.8){B}
\pstHomO[HomCoef=.62, PosAngle=-45]{S}{A,B}[C,D]
\psset{linecolor=black, nodesep=-1}
\pstLineAB{A}{S}
\pstLineAB{B}{S}
\psset{linecolor=black, nodesep=-.5}
\pstLineAB{A}{B}
\pstLineAB{C}{D}
\end{pspicture}
\end{center}
\end{document}
