3D Fractal Tree Based on Growth Simulation System

The paper proposes a new method of modeling 3D tree based on growth. In model the unique mode of tree´s growth can bring particular effect. We introduce the notion of force in a dynamic modeling system, strength of different kinds of force, as parameters, can influence and control the growing process. With the moving fractal mechanism, it can not only generate ordinary static trees, by changing force strength, the system can even simulate tree´s moving in breeze. Another virtue of our dynamic system is that it can conveniently control the outcome. We adopt different kinds of force to impact tree´s morphosis in the dynamic system. By adjusting arguments, the results can be smoothly changed and deliberately controlled
