基于物理的植物形变和运动建模

研究植物体的材料力学特性,用材质参数可调的剪向弹性杆体、柔性线体及其组合对植物体建模。给出各模型在外力作用下的力平衡方程推导方法,模拟了典型植物体模型在风吹动下的状态,结合模型提出实现真实感植物体动画的方法。建模方法的有效性由模拟结果得到验证,具有简洁、计算量小、对不同植物体普适性强的特点。

Physically based modeling of plant distortion and movement

Many plant bodies'mechanical models can be expressed by shearing elastic pole,flexible string or their combinations which mechanical parameters of materials are controllable.Illation procedure of mechanical balance equations of the models blowed by wind was desinged.New plant animation techniques were put forward.Then the distortions of bamboo,bulrush,and osier blowed by wind were simulated.The results of the simulations showed that the model and equations are applicable.
