摘要
首先回顾了人工植物形态结构模型中两种主要方法———L-系统与分形,并对其人工生命特征进行了分析。针对两种方法存在比较抽象,不易理解和使用等问题,该文提出了基于状态空间的人工植物结构模型。理论分析和仿真结果说明,该模型综合了L-系统并行生长与分形自相似特征,具有人工生命特征;能够连续、动态反映植物结构的生成,便捷易行;适合应用于诸如虚拟农业、虚拟植物科研与教学等领域。
This paper firstly reviews two modeling methods of form and structure of artificial plants based on L-systems and fractal,then a artificial plants model based on State-spaces theory is provided for both of them being abstract and difficult to understand.Theory analysis and simulation experiments show that the model combines characters of L-Sys-tems and fractal,it has the characteristics of artificial life,which can reflect plants structure parallel growing continually and dynamically and easily practice.The model is beneficial to researching on virtual planting,virtual studying and teaching for botany,etc.
