Yes ditto on this!

I woulk have to agree with that. Root bundles are an unconsiouse
but necessary element of trees that makes the recognizable as trees.
The first thing that caught my attention when I first started looking
for prcesses to create organic life forms in Pov was the total absence
of roots on Pov construced trees. You may not say to yourself that tree
ain't got no roots but something troubles away at the back of your
mind saying that tree is wrong some how.
For the record I could careless about an include file output. I make
so many changes to my files that I don't want to write a new file
every time I change one number to evaluate the change. Maybe a flag
to turn on output for the final version but not for every revision.

Govert Zoethout's tree include does include roots. Just look in this NG for
"T" by Govert Zoethout. Or see his website. I have done a translation of
some Dutch terms in the same thread.

Hello
Thanks for all the useful comments to the tree picture I posted a few days ago.
You can now find the MakeTree macro in pov.binaries.utilities.
And yes, it does roots (thanks Ken) and exports to *.inc files on request.
The zip file contains 6 examples you can use as templates.
Here are the rendered examples below.

Now this is SOO sweeeeeeeeeeeeet...
How many recursions do you use?
is it variable at choice(limbing)?
how... how . how...
Well, I think I have to get to the source now :-)
Thanx for the job. :-)

Thanks. Recursion levels are comprised between 4 and 7 (over 7 parsing time really
gets
bad).
The pictures (extree*.jpg) correspond to the examples extree*.pov in the zip file, and
the recursion level is called level0.

Yeah. These trees are the best ones done with(in) povray that I have
seen so far. All of them are very realistic.

Hi Gilles
1) Great Great Great
2) I didn't download your macro yet, so my question may be stupid : can you
create trees without any leaf ?
3) Your extree5 looks very much like a tree that (I believe) you can find
only in the Island od CURACAO in the netherland antilles : do you know this
island, this tree or ...

You can do leafless trees : see below the leafless version of extree1 and 2.
Just set the "leafproba" parameter to 0 (means 0 probability to have leaves).

I fear I don't... Just an happy chance I guess. In fact, the generated trees are
totally imaginary, and it may be quite difficult to replicate real tree
structures... This would require a complete model of tree growth & structure,
such as the one as these people have : http://iris8.cirad.fr/index.htm

I forgot to tell you the name of the tree : divi-divi
