This study investigates the generation and manipulation of radial grids for procedural city layouts, focusing on their potential for open-world games. Procedural city generation methods have gained prominence in various fields, including game development, architecture, and urban studies. This study introduces an organic city generation model utilizing procedural techniques, specifically adopting a radial grid approach as an alternative to rectangular grids. The paper presents three distinct mesh deformation techniques for altering the radial grid: One Point Attractor (OPA), Multiple Points Attractor (MPA), and Topography Informed Deformation (TID). These techniques are experimentally explored and empirically compared to achieve unique and heterogeneous growth patterns. As a result, the study develops modeling techniques for procedural city modeling based on radial grids that enable organic city generation and can be used in an open world game environment.
