摘　　要：为提高虚拟城市场景建模的灵活性和高效性,提出一种基于形状语法的过程式城市场景建模方法。该方法作用于初始大小的网格图形,使初始网格经由一系列形状规则的递推过程和路径规划等,完成路网生成和道路分级规划;实施原创性设计策略,通过定义不同模型生成的形状语法规则,过程式自动生成城市场景。实验结果表明,基于形状语法的过程式城市场景建模方法可以灵活、高效构建城市场景,具有一定研究意义。To improve the flexibility and efficiency of virtual city scene modeling,a processual urban scene modeling method based on shape grammar was proposed,which acted on the initial size of the grid pattern,so that the initial grid could complete the road network generation and road classification planning through a series of recursive process of shape rules and path planning.An original design strategy was implemented to automatically generate urban scenes by defining the shape grammar rules generated by different models.Experimental results show that the shape grammar can construct urban scenes flexibly and efficiently with a certain research significance.
