This tool was developed for the movie Tangled, and was based upon my observations of trees in their natural element, as opposed to the trimmed and maintained trees of golf courses and parks. I chose to build a particle based system instead of an L-systems approach. By using particles as agents I could add awareness of the environment to the growth process, and introduce branch death and light/gravity/wind/shape tropism. It also had the advantage of building the rig at the same time it built the tree, so subsequent animation and lighting attributes were accessible.
