WHAT IS CITYENGINE?

From Esris website:

CityEngine is a desktop application that provides unique

interactive design and procedural modeling capabilities for the

efficient creation of 3D cities and buildings.

It improves urban planning, architecture, and design. Use its 3D

visualization power to see the relationships of projects, assess

their feasibility, and plan their implementation. CityEngine helps

you make quality decisions that benefit your community for

decades.

AKA Professional SimCity

WHAT IS PROCEDURAL MODELING?

Procedural modeling means that 3D geometries and textures are

constructed using rules (procedures) instead of labor-intensive

manual modeling.

A single procedural rule can be used to generate many 3D models.

For example, the rule can make use of feature attribute

information stored in GIS datasuch as the number of floors,

roof type, wall material type, etc.to generate a series of

alternate 3D models that accurately represent the properties of

each feature. The more attributes you have, the more accurate

the generated model can be.

WHY DO I WANT TO USE CITYENGINE?
