[GRASS5] v.trees3d

[Jachym Cepicky]

Hallo,
after some time, I tryed to rewrite my old trees.pl script to C with
database support for attributes height, diameter and species for each
tree.

The code is not very nice, but I'm not able to make it nicer now - my C
skills are very poor. But it works. If anybody could
rewrite/show me the way, how to write it better, I will be thankfull.

For some screenshots you can have a look at
v.trees in=points out=forest elev=dem beech=50 oak=50 hvar=20 vvar=5
height=25
