摘要
研究虚拟植物生长发育过程,为克服传统建模中玉米器官生长形态定义不够精确和生物学意义缺失,采用实际田野实测,引入动力学,给玉米植株生长模型赋予生物学意义,提出玉米植株生长造型更为精确的描述,根据图形学技术构造玉米植株生长过程的三维几何形态,对不同生长期的形态变化进行动态仿真,实验结果表明与实际拍摄的玉米植株生长发育过程一致。模型可控性强、真实感强,能较好地仿真玉米植株的生长过程。
In order to get rid of some shortcomings in traditional growth modeling of maize organs,such as lacking precise definition of organ growth morphology,lack of biological meaning and ideal simulation results.The dynamics is introduced to the studies of the growth modeling,based on the field observations,with biological meaning and more precise definition given in the new modeling.By using graphics technology in constructing 3D morphology of maize organs growth,the morphological changes of the maize organs are dynamically simulated in its different growth stages.The experimental results basically reflect the photographed actual growing process of maize organs.The new model is highly controllable and has high sense of the reality,being able to well simulate the growth process of maize organs.
