Thanks for posting the link, it does seem to be cool little treegen. Definitely useful !

this is the one that runs off Java, right?

yes , looks very useful.

It's a great litte app, but be warned:
The poly-count of the resulting .obj's goes through the roof...

Cheers,

Guess I'm pretty dumb, how do I use it?

I downloaded this a long time ago and couldn't figure it out either.

Double click on the arbaro.jar file to start it up, you will probably need java installed. Then either start with a tree from scratch or load up one of the premade ones. You can click on the little grid in the left to edit the various settings. Clicking on the blue link that comes up in the bottom left will give you a description of what each setting does. The diagram on the right also gives you visual clues for the same. The slider on the bottom rotates the tree around so you can see it from different angles.

The rest is just experimenting till you get a tree you like and exporting it to obj. And yes it will be pretty heavy.

On the site there is a reference to a paper which describes the model used to generate trees and its parameters; unless you get, print and study this paper, do not expect to create anything sensible; sorry, but tree generation is a complex subject which requires complex tools and specialized knowledge.

You are also likely to need a 3D modeling app capabable of reducing polycount.

Bye!!!

Or you can just use your eyes :P

Duh clicked everything in there and didn't see that the abaro.jar was an executable....thanks! Yup think I can figure this out and have a few programs I can use to reduce the poly count. Will get the paper and print it out but it looks pretty intuitive.
Thanks for the heads-up on this!

or you can just get Bryce 5, and have trees that way...;) Xfrog also does trees, but it's spendy...

But can Bryce trees be exported to other apps?

I asked about that in the past, unfortunately not...

If anybody is interested in knowing more about plants in 3D graphics, this page (vterrain.org/Plants/) is a good start. B.t.w., simulating and/or modeling plant growth and shape is an active and extensive academic field, not only for GC reason but also for more biogical ones.
