| 摘 要： | 自然界中遍布着千姿百态的植物,多年来,植物模拟技术作为不规则物体建模领域的一个重要分支,一直被众多的科学家所关注.植物枝条弯曲形状的模拟是植物模拟的重要内容.针对枝条弯曲形状的模拟,分析了植物枝条的生物力学模型,将材料力学中弹性杆件的简易受力模型与基于L系统的植物模拟算法相结合,模拟了重力和趋向性对于枝条弯曲形状的作用,有效地生成了自然逼真的植物枝条弯曲形状.

| Abstract: | Various plants spread all over the world. As a branch of modeling for irregular object, plants simulation attracts many scientists' attention. Bending branches simulation is an important thesis in plants simulation. To solve the question of bending branches simulation, biomechanical model for bending branches was analyzed in this paper. The model of elastic rod in material mechanics was incorporated with arithmetic about plants simulation based on L-system. Then, the effect of gravity and tropism on the shape of branches was simulated. The realistic bending branches were got. |
