Rule
Creation
Procedural Modeling Provides a Flexible 3D Design Environment
Supporting a Rapid and Repeatable Process
Steps
• Author Rules (or use Library)
• Generate Multiple Design Scenarios
• Evaluate Alternatives
Particularly When Projects Require Many
Iterations

• Interactive
• Multiple Views
- Realistic Display
- 3D Thematic Rendering
• Performance Reporting
- Driven by Attributes
- Visualized Dynamically

CityEngine and Procedural in 2016
• CityEngine will have two releases- 2016.0 – Q2: Focused on better platform integration through services
- 2016.1 – Q3: Focused on UI/UX
• ArcGIS Pro- Better support for attribute based reporting in 1.3
- Better support for dynamic reporting in 1.4
