油菜虚拟生长的研究

The search on virtual growth of rape plant

虚拟植物即应用计算机模拟植物在三维空间中的生长发育状况,是近20年来发展起来的一种新兴技术。本文通过对虚拟植物研究范围的探讨及虚拟软件L系统的介绍,分析了植物外部形态的特点,并结合油菜生长过程中各个器官形态变化规律的本质,动态地模拟出油菜在不同生长阶段的形态,尤其是在茎杆的模拟,实现了用户与虚拟油菜的交互式调控,总结了L系统和油菜分枝的数据结构,这更有利于准确动态模拟出油菜的主体形态结构。最后,本文对油菜与环境的相互作用及其相关方面等进行了展望。

Virtual plant is the plant＇s growth and development in the three dimension by the application of computer simulation, and it is the emerging technology in recent 20 years.The paper discusses the virtual plant＇s scope of analysing,and introduces the virtual soft L_system,analysises the charateristic of external morphology of plant,and combines the essence of morphological change of each organic during the growth process of the rape,dynamic simulate the configuration of the rape during the various growth phase,especially simulates the stalk,and summarizes the structures of the data about the L_systems and the branches of rape,it is more favor of accuracy simulate the boby morphological structure.Finally,the paper gives the aspects of the interaction between rape and environment, and another aspects.
