ArcGIS CityEngine is a  three-dimensional (3D) modeling software application developed by Esri R&D Center Zurich (formerly Procedural Inc.) and is specialized in the generation of 3D urban environments. With the procedural modeling approach, CityEngine supports the creation of detailed large-scale 3D city models. CityEngine works with architectural object placement and arrangement in the same manner that  VUE manages terrain, ecosystems and atmosphere mapping. Unlike the traditional 3D modeling methodology which is using Computer-Aided Design (CAD) tools , CityEngine improves the shape generation via the rule-based system and data sets—similar as the Geographic Information System (GIS)  . Due to this dominant feature , CityEngine has been broadly used in academic research or building virtual environments , e.g., urban planning, architecture, visualization, game development, entertainment, archeology,  and cultural heritage. After being integrated with the Building Information Model (BIM) , CityEngine can visualize the data of buildings in a larger urban context, enhancing its working scenario toward real construction projects.
ArcGIS CityEngine is a commercial three-dimensional (3D) modeling software application developed by Esri R&D Center Zurich (formerly Procedural Inc.) and specialises in the generation of 3D urban environments. Using a procedural modeling approach, it supports the creation of detailed large-scale 3D city models. CityEngine works with architectural object placement and arrangement in the same manner that software like VUE manages terrain, ecosystems and atmosphere mapping. Unlike the traditional 3D modeling methodology which uses Computer-Aided Design (CAD) tools and techniques, CityEngine takes a different approach to shape generation via a rule-based system . It can also use Geographic Information System (GIS) datasets due to its integration with the wider Esri/ArcGIS platform . Due to this unique feature set , CityEngine has been used in academic research and built environment professions , e.g., urban planning, architecture, visualization, game development, entertainment, archeology, military and cultural heritage. CityEngine can be used within Building Information Model (BIM) workflows as well as visualizing the data of buildings in a larger urban context, enhancing its working scenario toward real construction projects.
