Trees are part of the general scenery around us, so it is important to model and animate them. Current solutions build individual trees then add wind; all build single trees and require skilled interaction, making them expensive. This talk explains how easy trees allows users to create a forest of trees that look and move naturally. The only demand on the user is to outline a tree, in one frame of an ordinary video. The dynamic tree model acquired can then be used to populate a forest of moving individuals, at the touch of a few buttons. Simplicity for users rests on the use of probabilistic generative models to create new trees, and a Bayesian approach to reconstruct three dimensional models from two dimensional ones. Easy trees outputs high quality tree model, they are unique in including motion in all modeling stages. All tree models can be rendered in a wide variety of ways, from photorealism to cartoons, in any season. Similarly, users have complete control over motion, wind strength is easy to change.
