Esri 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.
