PM4Urban: A Scriptable Parametric Modeling Interface for Conceptual Urban Layout Design Using PM4VR

Conceptual urban layout design is a critical aspect of urban planning and architecture design that focuses on the arrangement and organization of physical spaces in a city or urban area. However, traditional urban layout design requires sophisticated tools to visualize and manipulate large-scale layouts efficiently. This paper introduces PM4Urban, a scriptable parametric modeling interface designed to enhance and facilitate conceptual urban layout design experience. By extending the PM4VR framework with new features, PM4Urban enables urban planners and architects to dynamically create, modify, and visualize complex, realistic, and immersive parametric urban environments in virtual reality. After being validated through numerical experiments, the PM4Urban interface supports various parametric design techniques, offering a versatile solution for early-stage urban design and planning.
