AI-Powered Generative Design for Efficient Park Space Creation


Core Concepts
This study proposes an AI-powered generative design framework that can rapidly generate realistic and customized 3D park models from basic site conditions, enabling efficient and interactive park space design.
Abstract
The study presents a comprehensive framework for generating park space designs using a three-phase approach: Plan Generation Design: An automated plan generation system is developed based on deep learning technology, capable of rapidly generating a large number of complete design layout drawings solely constrained by the layout of internal park elements. 3D Park Automated Generation Design: Building upon the data generated by the plan generation system, a parametric modeling system is developed to swiftly construct three-dimensional park models. Analysis and Visualization: A model processing system is constructed to enable rapid analysis and modification of the generated three-dimensional parks, producing visual renderings from different perspectives. The key highlights of the framework include: Rapid generation of park layout designs that meet the designer's perspective based on site conditions, leveraging AI-assisted technology. Vectorization and three-dimensionalization of various types of landscape design elements while preserving design fidelity. Integration of an analysis and visualization module that allows for landscape analysis on the generated 3D models and produces node effect diagrams, enabling real-time design modifications. The experimental results demonstrate the effectiveness of the proposed framework in generating park designs of different scales, with diverse vegetation arrangements and element layouts. The generated 3D models are consistent with the layout plans and can be further refined and rendered for practical use.
Stats
The study trained a CycleGAN model using 194 pairs of park plan design images and their corresponding layout labels. The generated layout plans were then processed to extract vector data for different design elements, including buildings, pavement, water, green land, roads, and plantings. The extracted vector data was used to parametrically generate 3D park models using the Grasshopper platform.
