Procedural CityEngine | The manual modeling of 3D cities is very time-consuming. With CityEngine this process can be accelerated by magnitudes - resulting in impressive 3D models at lower production costs. See whats new : http://www.procedural.com/cityengine/whats-new.html
CityEngine Feature: 3D Land Use Zoning Zoning regulations are text-based descriptions (per city) of allowed building volumes, usage, and density. They are the main tool defining the image of a city and/or growth/development investment money. CityEngine allows you to specify, visualize, analyze, and store zoning regulations in 3D.
