摘要
研究虚拟植物生长的仿真应用较广。针对数字娱乐领域中用于虚拟场景的植物形态-功能仿真的有限需求,为了提高真实性,提出了一种通用的基于环境变化的虚拟树木动态生长的仿真模型,来仿真各种树木的生长过程。采用L系统描述树木的拓扑结构,结合植物学相关知识,引入了环境因素对树木生长的影响,将树木的生物学特性进行抽象与加权处理,建立了树木生长与光照信息交换的简洁算法。仿真实验结果表明,该模型能较好地反映了环境因素变化对植物生长的影响,较真实地仿真再现了树木的动态生长过程。
A simulation model for the dynamic growth of the virtual plant based on the environmental factor is presented in this paper. Using the L-system,the tree structure model for the growth process simulation of various trees is established. According to the botanical knowledge,the effect to trees from environmental factor is introduced through abstracting and weighted processing of the tree biological characteristics and the concise algorithms for interactive effect between tree growth and their sunshine is established. The simulation results show that the model can reflect the influence of the changes in environmental factors on plant growth,and simulate the dynamic growth of trees better and more realistically.
