Leaf Movement Simulation

This paper presents a method for the animation of leaf movement. Leavesare classified into two classes: moveable and non-moveable. For moveableleaves, their movements consist of two parts: leafstalk rotationand leaf surface rotation. For each rotation, a movement model wasconstructed and the movement was computed based on each model,respectively. The final leaf movements were obtained by superposition ofthese two rotations. The method's principle is simple and easy to use.
