  1. City Engine: Getting Started Geri Miller

  2. Overview • Topics • Introduction to CityEngine • Working with CityEngine • Building a city

  3. What is CityEngine? • Procedurally generate 3D urban content Geometry + Attributes + Rules

  4. What is CityEngine? • Interactive design in 3D

  5. What is CityEngine? • Interactive design in 3D

  6. What are the uses for CityEngine

  7. How is 3D city content created ? (1) • Together, geometries, attributes, and procedural rules are used to create 3D urban content Geometry Rules Attributes

  8. How is 3D city content created ? (2) • Geometries, attributes, and rules result in a procedural city modeling • Rule-based 3D cities

  9. What is procedural modeling? • 3D model creation using rules/algorithms Iterative refinement
