What Is a 3D City Development Tool?
A 3D city development tool is software that enables teams to create, visualize, and simulate urban environments. These tools range from AI-powered 3D model generators and procedural city builders to GIS-integrated platforms and real-time engines. They help planners, architects, developers, and game studios design city-scale environments, test scenarios, and present photoreal interactive experiences. The best 3D city development tools streamline workflows from asset creation to visualization while supporting data accuracy, collaboration, and cross-engine export.
