In general I am making 3D-Coat whole time
www.3d-coat.com/files/3d-Coat-2-trees.exe
It is free to everyone who has purchaced 3D-Coat. At least for some time (maybe it will cost something when I will make rich export functions and make it white&furry).
It is not very user-friendly, but anyway, easy enough. It is not 100% made, sometimes I will update it if you will like it.
Enjoy!
There is screenshot:
*edit: I have updeted the link, now it has correct export functions.
- Export for games - exports leafs as a random planes. To use in game you should convert it to your own format and rendar billboards to look at camera
- export for render - contains 6x more random billboards
mtl file and textures are also exported.
In general it is serious app, there is many competetive options:
1) deleting invisible faces inside parent root
2) branches can grow not only directly under some angle like in SpeedTre but starts from tangent direction and follows with random angle in some direction
3) roots like a kind of branches
4) adaptive simplification of branches in dependence on curvature (not a simple equidistant sampling like it is usually done)
5) possibility to use multiple leafs types on the one tree (most of generators use single leaf clone).
5) generating LOD-s
