Physically-based Simulation of Leaves' Movement

This paper gave a method in tackling the animation of leaves’ movement. Various kinds of leaves were classified into two classes: moveable and non-moveable. For moveable leaves, their movements are consisted of two parts: leafstalk’s rotation and leaf surface’s rotation. For each rotation, a movement model was constructed and the movement was computed based on each model, respectively. The final leaves’ movements were obtained by superposition of these two rotations. The method’s principle is simple and easy to use. However, the effect is good.
