基于物理的阔叶植物仿真

Physically Based Modeling and Simulation of Broad-leaved Plant

提出了一种基于物理的阔叶植物实时模拟算法,利用改进的半刚体结构对叶片进行建模并绘制出较为真实的动画。该方法根据阔叶植物的自然属性,在其枝干、茎、叶等分层处理的基础上,通过叶片平行脉位置方向的对角线弹性约束关系来有效控制叶片在风中的形态,并针对本模型的特点建立了具有特殊的风力模型。通过与其他模拟系统进行比较,该算法的模拟效率较高且模拟结果较为真实。

The modeling and simulation of Broad-leaved plant moving with the wind were described. A physically based animation method known as the semi-rigidity model was used to realistically simulate the movement of every part of broad-leaved plant. Its emphasis is on the overall geometrical structure of the plant according to botanical principles, including hierarchically transaction of the part of branch and stem and foliage, and special force model for our approach. The shape of plant in wind can be efficiently controlled through the constraint of the parallel venation on leaves. By comparing with the other simulation methods, the experimentation indicates that the method is not only effective but realistic.
