摘要: 仿真局部环境对植物生长的影响,特别是在剪枝条件下的植物生长状况,对数字农业的发展和虚拟园艺设计具有重要意义。已有的成果运用环境敏感L系统实现了二维植物在正方形边界内的剪枝生长仿真,但未能模拟真实植物生长受环境的影响。在此基础上,运用三维植物生长模型,实现了三维植物在剪枝条件下的生长过程仿真。实验结果表明,环境敏感L系统能够很好地模拟真实植物和外部包围盒之间的交互,为下一步研究植物同其他外界环境因素的交互打下了基础。

Abstract: Simulation on local environment factors to the growth of plant, especially pruning is important to the research of the digital agriculture and virtual gardening. Although a two-dimensional tree model constructed by environmentally sensitive L-system is used to simulate its growth under 2D clipping box, real plant development process response to pruning is lacking. By combining it with a real plant development process model, a model of trees response to pruning is proposed. The experiments show that environmentally-sensitive extension of L-systems can make a better simulation on the interaction between a developing plant and its bounding box, and build a base for next step of research.
