2 Agenda CityEngine Refresh RPK s, what can they do? (10 min) Overview of Procedural Modelling (5 min) CGA 101 (20 min) Creating Rule Packages (5 min) Important Tips for RPKs (5 min) Q&A

3 What is CityEngine?

4 Why?

5 Rapid and Repeatable 3D Modeling Steps Author Rules (or use Library) Share as RPK (publish to AGOL) Consume in CityEngine, Pro, or CE SDK B A New Rule Creation CAD / 3D Sketching Procedural Design Particularly When Projects Require Many Iterations Number of Iterations

6 Rule Packages = Rules (CGA) and Assets

7 What is an RPK? A zipped file containing A rule from CityEngine, written in Computer Generated Architecture (CGA) The assets associated with that rule May be locked, to prevent reading of rule code or unpackable for code sharing. What can RPKs do? Rule Packages = Rules (CGA) and Assets Content creation - Convert simple data into useful 3D content - Clean up existing data to make it easier to use - Create derived analytic data Procedural Symbol - Override current symbology for the task at hand

8 RPKs in ArcGIS Pro Symbology

9 RPKs in ArcGIS Pro Analysis

10 Using Rule Packages Summary Share them either a file or as item online - Must be available locally to be consumed Consume in: - ArcGIS - Features from CityEngine Rules GP tool - Requires schema-matching for parameters to be applied - ArcGIS Pro - Add as a procedural symbol to either polygon or multipatch data - Can manually configure the schema within Pro - 3 rd party 3D apps - Using the CityEngine SDK

11 CGA as LegoScript + parameterized instructions + Legos

12 Shapes = Scope and Geometry

13 Shape Operations modify scope and geometry

14 Rule = Sequence of Shape Operations Envelope --> case scope.sx*scope.sz > 6000: 15%: split(y){ '0.9 : Tower ~3 : s('0.8,'1, ~1 : s('0.6,'1,} 15%: split(y){ 'rand68 : T ~rand(0.5,1.5): s ~1 : s 15%: split(y){ 'rand48 : Tower ~1 : s('ran 15%: split(y){ 'rand48 : Tower ~1 : t('ran else: Tower else: Tower Scripting for Shapes

15 Challenge: Creative Rules

16 DEMO

17 Important Tips Assets - All will be included beware the random use of textures and models - Has a huge impact on file size consider multiple / focused RPKs Using Tags / Annotations - Define @InMesh Parameters (ie: the attr definition) - Use it as much as needed but no more - Use a good name shown on the UI - Match to data model auto-connect matching names - Set (v1, v2) - Provide @Angle Protect the CGA (as needed) - If your rule is something you sell, or has IP, then protect it

19 Creating a RPK

20 Sharing / Consuming Rule Packages Write CGA rules in CityEngine Share as rule package - Within your organization - Item on Portal - Item on AGOL ArcScene 10.2 Consume in: - ArcGIS (GP Tool) - ArcGIS Pro (Symbology & GP Tool) - 3 rd party 3D apps - CityEngine SDK Maya

21 Rule Packages on ArcGIS Online Item type on ArcGIS Online Esri Rule library ArcGIS Marketplace - planned for future releases

24 New CGA Function: 2016 and 2017

25 Procedural Runtime (CGA) Area split Inner rectangle 2.0 Primitives Extrude, roof & insert extensions Cleanup for normals, double-sided,

26 Normal Split

27 Split By Area

28 Inner Rectangle Get Remainder

29 Inner Rectangle Get Rectangle With Largest Area

30 Built-in Primitives Rule of the week: Taj Mahal

31 Built-in Primitives Specify Resolution

32 Insert With Native Size 115m 151m 127m Maya CityEngine

33 Soften Normals all hard edges soft edges only between faces with similar orientation all soft edges

34 Conform Normals inconsistent vertex ordering and normal directions consistent vertex ordering and normal directions
