[pstricks] suggestion for pst-3dplot

[Markus]

Dear Herbert!

I've attached a pdf - have a look. (Barth, Krumbacher, Barth: 
Anschauliche Analytische Geometrie, Oldenbourg-BSV-Verlag). The 
comments have to be removed. They do not fit the conversion.

I'll think about a mistake this afternoon - after Christmas-shopping.

Thanks a lot!

Markus
