Research on Motion Simulation of Trees Model in Wind Filed

Abstract

With the development of computer animation and demands for gaming, the motion simulation of trees in wind filed has become one of the research hotspots. In order to better simulate the 3D motion of trees to wind filed in the natural environment, this paper proposes a method to establish real-time animation visualization of trees in the wind. The research focus is making the process of performance of ranches swaying motion become more real, layered modeling was carried out on the branches and combining the theory of fractal iteration for simulation, making the effect of wind field on the branches can carry on the hierarchical structure to analysis and calculation in detailed, so as to achieve good swing results. This paper implements a dynamic simulation demonstration system of trees in the wind based on fractal iteration system to be consistent with branches in the wind with the nature of the scene. Therefore it can generate both satisfied visual effects and dynamic images that meet the real-time requirements.
