Abstract
Trees, in particular the dynamic waving of trees plays a very important role in the natural scenery of landscape. Unfortunately, due to the high level complexity of the structure of trees and the highly varying properties of trees’ components, physically-based simulation of trees’ motion becomes extremely a difficult task. As an effort in tackling such a problem, a solution is proposed and implemented in the paper. By this solution in the control and simulation of the motion of trees blown by wind, the behavior of moving branches of trees is simulated based on the contemporary non-linear mechanics, and that of waving branches based on the principle of mechanical wave.
For the construction of tree’s model, a method is also designed and implemented in the paper to extract the model of trees from static images. Thus, a new approach is created in the work to allow the trees in a static environment expressed by images waving with wind dynamically, through a process of two stages—reconstruction of trees from their image followed by a physically-based calculation of trees’ animation from the model reconstructed.
A test example of animation has been provided to show the feasibility of the approach.
