What is CityEngine? • Interactive design in 3D

What is CityEngine? • Interactive design in 3D

What are the uses for CityEngine

How is 3D city content created ? (1)

• Together, geometries, attributes, and procedural rules are used to create 3D urban content

Attributes

Geometry

Rules

How is 3D city content created ? (2)

• Geometries, attributes, and rules result in a procedural city modeling

• Rule-based 3D cities

What is procedural modeling? • 3D model creation using rules/algorithms
