摘要
采用"根箱法"分析水稻根系在土壤中的分布形态,并应用三维球形海龟几何解释,结合参数L系统推导出产生式规则;采用二次B样条插值函数的方法,设计了水稻根系参数L系统,并使用Visual C++和Open GL标准图形库,实现水稻根系生长的可视化。对该模型进行实验验证,获得的标准误差趋近0,一致性指数趋近1,参数L系统模型可以有效模拟水稻根系的生长。
In this paper,the"root box method"was used to analyze the distribution pattern of the rice root system in soil.The production rule is derived by using the 3D spherical turtle geometry interpretation based on the parametric L system.The quadratic B-spline interpolation function is used to design the parametric L system.The visualization of rice root growth is realized by using Visual C++and Open GL Standard Graphics Library.The model is verified by experiments with the standard error approaching 0 and the consistency index approaching 1.It is found that the expected goal is achieved.
