Description

Vitruvio brings ArcGIS CityEngine’s procedural modeling power to Unreal Engine. It enables generating procedural buildings using CityEngine’s generative runtime and shape grammars. Generated buildings remain procedural at all times. Attributes such as height, style or appearance can be modified in real-time to generate new building variations. Vitruvio can also be used in a packaged product and buildings can be generated dynamically at runtime.

Important: Proceed to the official GitHub page to download Vitruvio. The latest release is not available in the Epic Games Launcher any longer.

Technical Details

Vitruvio uses CityEngine’s Procedural Runtime (PRT) to generate buildings and cities. As input it takes a rule package (RPK), an initial shape and a set of attributes.

The generation process starts with the initial shape (which can be any Unreal Static Mesh or Spline) from which shape grammar rules are expanded. The shape grammar rules, together with all necessary assets, are bundled in RPKs which can be exported from ArcGIS CityEngine and imported into your Unreal Engine project. The attributes are parameters that control shape generation. They can be changed in the Unreal Editor or dynamically at runtime.
