Abstract: In order to simulate broken branches caused by big wind quickly and realistically, a simulation algorithm was proposed. Firstly, a wind model was presented with reference to noise function. Then, mechanics of materials was applied to analyze the movement details of branches so as to get the deformation parameters of branches and the parameters were then introduced into the interpretation on the fractal geometry of trees. At last, on the basis of these models, a visual simulation method for broken branches was designed. This method could obtain visual simulation results of broken branches with different strong wind by modifying the wind model parameters. The simulation results show that the algorithm which provides new ideas for estimating disaster of trees is right and efficient.
