There were a lot of shortcomings in my treegenerator "tomtree.inc" (definitely not the last) I have removed.
Some setting-points I've added, the deep of ramification I've improved and there are some additional more realistic height_field-leaves (HF_LEAF.zip) on my website (see the example picture).

Unfortunately the older setting-incs produce different trees with the new tomtree.inc (18.8.99) or rather break off with an error (undeclared...) because of new keywords. Of course tomtree.zip contains new setting-inc files (and a practice inc "testtree.inc" with very simple (straight) settings, so you can try step by step...).

I hope you have enough patience with tomtree.inc!?
