PRT takes as input an initial geometry and then applies a given rule package (= CGA rules authored in CityEngine) to generate more detailed 3D geometry as output. The core of CityEngine is its unique geometry generation engine, called Procedural Runtime (PRT). STL support is not provided out-of-the-box in CityEngine, but you can develop your own STL exporter as described below.ģD apps which need a procedural geometry engine. A simple use case example is 3D printing where the STL geometry format is often needed. This means the SDK enables you to develop CityEngine plugins to read or write additional 3D and image formats or your own proprietary 3D data format. The CityEngine SDK can be used for the development of:Ĭustom importers and exporters for CityEngine. Using the CityEngine SDK, a number of open source plugins and APIs have been built, allowing to integrate CityEngine technology into other tools. This is the official site for the SDK of CityEngine, a 3D city modeling software for urban design, visual effects, and VR/AR production.
