摘要
为真实仿真植物茎生长过程,对植物茎以及分枝进行更细粒度划分,把茎的生长按分生区、伸长区、成熟区三级结构划分依次迭代,结合参数L系统仿真植物的形态几何结构,达到了良好的效果。对植物分生区设置flower、subaxis、leaf 3种侧芽因子,以提高植物生成不同器官的可控性。通过仿真实验表明细粒度划分能够降低参数L系统的复杂度,较真实地仿真植物的生长过程及植物学现象。
In order to simulate the growth of plant stem,plant stem and branches were divided into fine grit,and the plant growth process was iterated by dividing the stem into tertiary structure of meristematic zone,elongation zone,maturation zone.The parametric L-systems theories were applied in simulating the geometry shape of the plant.This method can achieve a better result.For plant meristematic zone,three kinds of lateral bud factor of flower,subaxis,leaf were set to improve the controllability of different organs in plant growth.At last,the simulation experimental results showed that this method could reduce the complexity of parametric L-systems,and make the real simulation of plant＇s growth process and the phenomena of botany.
