Research on the Model of Developing and Generating Morphology for Virtual Plants Sticks

文章提出了一个新的植物形态生长的动态模拟方法,该方法基于状态空间理论,将植物的生长视为三维状态空间中状态矢量的运动过程,并综合考虑了趋光作用与分枝自重对植物形态的影响。该模型既能连续、动态地模拟植物并行生长,又能反映植物形态结构与生长机理的关系,模型直观,易于理解,为虚拟农林以及计算机动画等提供了具有实际应用价值的研究方法。

In this paper,a new model based on State-space Theory for plants morphology developing is provided.According to the model,plant developing is regarded as moving process of state vectors,and the effect of plant weight and light on plant morphology is considered comprehensively at the same time.The model can reflect both parallel growing of plants continually and dynamically and relationship between plant morphology and growing physiology.The model is directly perceived and easily understood,and provides a practical research method for virtual agriculture,forestry and computer animation as well.
