Blender plugin produced as part of my undergraduate dissertation: Procedural generation of tree models for use in computer graphics.
Thanks to the awesome work of Luke Pflibsen-Jones you can install the zip through the Blender addon UI (or drop the extracted folder into your blender addons directory) and enable the plugin in user settings to start generating trees - now with a complete customisation UI!
Download the latest version from here.
(WIP) Docmentation is available on the Wiki.
