树在风中的摇曳--基于动力学的计算机动画

树木森林在自然场景的构成中占有很重要的地位，尤其是树在风中的摇曳更是组成了一个幕幕动人的景象。但是由于树结构的高度复杂性，给这一问题的研究工作带来了极大的困难。

GOING WITH WIND--PHYSICALLY BASED ANIMATION OF TREES

Trees play the most important role in the natural scenery of landscape. It is surely magnificent in many fields if we could physically simulate the waving motion of trees by computers. 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 difficulttask- As an effort in tackling such a problem, a solution has been proposed and implemented in thepaper. 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. A test example of animation created solely by a primary graphics library is provided to show the feasibility of the approach.
