基于分形理论的口袋公园景观设计

A Study of Pocket Park Landscape Design Based on Fractal Theory

为了能够提高口袋公园设计创新性,增加其设计手段的多样性,本研究选择了分形理论中的3种算法——随机中点位移算法、菱形-正方形细分算法和基于LOD的四叉树法,应用于口袋公园设计实例仿真中.仿真结果表明:菱形-正方形细分算法在使用性能和平滑度上显示出较高的优势,为今后的口袋公园的景观设计提供了一种新的理论和方法.

In order to improve the innovation of pocket park design and increase the diversity of design methods,three algorithms of fractal theory are chosen:the random midpoint displacement algorithm,diamond—square segmentation algorithm and quad-tree algorithm based on the LOD,which are applied to pocket park design example simulation.The simulation results show that the diamond—square segmentation algorithm has advantages on the performance and smoothness,which can provide a new theory and method for the design of pocket park in the future.
