摘要
针对目前虚拟城市建模存在的不灵活、开发效率低下等缺点,提出一种可控随机虚拟城市过程化生成方法。不依赖于道路和建筑物等图像测量数据,基于用户设定的城市规模、街区尺寸、河道、功能分区等约束条件,结合城市规划原理,通过一系列过程化生成方法,快速且灵活地构建格局合理、拟真度较高的大规模虚拟城市三维场景。实验结果表明了该方法的有效性和自动建模的便携性。
Aiming at the disadvantages of inflexibility and low development efficiency in virtual city modeling,a process generation method of controllable random virtual city was proposed.Without relying on the image measurement data such as roads and buildings,the user set constraints such as city scale,block size,river channel and functional zoning were used,the principle of urban planning was combined,a series of process generation methods was used,a large-scale virtual city 3D scene with reasonable pattern and high fidelity was quickly and flexibly built.Experimental results show the effectiveness of the proposed method and the portability of automatic modeling.
