I have written a little treegenerator (is this a right word?) as an include-file
for Povray. You can view some quick examples on my website
www.aust-anfertigungen.de
> 3D-Visualisierung > Baumgenerator.
Have a look on the first results and let me know, if it's worth to put
the include-file on the web for free download.
It isn't really finished yet - I want to add some more options for
the wild order of virtual plants.
