Modeling an urban environment with CityEngine usually implies the individual stages of the pipeline given in the image below.
Whether you work in urban planning, architecture, entertainment or simulation, CityEngine provides a way to transport your data. You can transport line data, shape data (footprints), and 3D geometry to and from CityEngine. Data interoperabilityĬityEngine supports the industry's most common formats for both import and export. To have control repetitive tasks, create formatted reports in file format, or automate other specific actions, use Python scripting to further streamline the workflow in CityEngine. The user interface (UI) in CityEngine can be adapted to tasks, including rule creation, working on the street network, editing attributes with real-time feedback, or studying the statistical reports of your current city's development. Your buildings are rebuilt while you edit the width of the surrounding streets. Streets, sidewalks, and whole blocks, which form the specific urban context, adapt efficiently to your input and allow you to design the layout of complete cities.Īll the geometries that depend on the layout of the underlying dynamic city layout are also updated on the fly. The dynamic city layouts allow you to create interactive street networks that automatically update in real time. To learn more about procedural modeling, see Grammar-based modeling. The commands provided in the CityEngine CGA shape grammar, such as extrude, split or texture, are widely known commands in most 3D applications, and you can adapt them to create complex architectural forms. CityEngine features Procedural modeling core Instead of the classical intervention of the user, who manually interacts with the model and models 3D geometries, the task is described abstractly, in a rule file. The computer is given a code-based procedure that represents a series of commands-in this context, geometric modeling commands-which then will be executed. The main concept of CityEngine is the procedural approach toward modeling efficiently.
