Simulation of bending branches is important for vivid image synthesis of plants. In this paper, a simple mechanics model is presented for calculating branches bending from the perspective of computer graphics. An algorithm for branch bending based on dual-scale automaton model is developed. The algorithm needs only a few parameters, but can generate natural and realistic branch bending curve. It can also represent the process of dynamic bending while the plant is growing. Several examples are given in the paper to illustrate the advantages of the algorithm.
