The Esri CityEngine is based on the procedural runtime, which is the underlying engine that supports two geoprocessing tools in ArcGIS and drives procedural symbology in ArcGIS Pro. The CityEngine SDK enables you as a 3rd party developer to extend CityEngine with additional import and export formats. Moreover, you can integrate the procedural runtime in your own client applications taking full advantage of the procedural core without running CityEngine or ArcGIS.

This document explains how to install the CityEngine SDK and how to work with the source-code examples contained in this repository. The Esri CityEngine SDK is packaged into three parts:

• This git repository with the example sources.
• An archive with the SDK binaries and documentation (whitepaper and API reference).
• An archive with example data (e.g. rule packages and initial shapes).

The archives are available for download at the corresponding github release page. See installation instructions below for details.

• v1.3.1969 (2015-06-17, CityEngine 2015.1)
• v1.3.1888 (2015-03-31, CityEngine 2015.0)
• v1.2.1591 (2014-09-01, CityEngine 2014.1)
• v1.1.1471 (2014-05-29, CityEngine 2014.0)
• v1.0.1209 (2014-01-15, CityEngine 2013.1)

1. Clone or download this repository
2. Download the SDK binary archive from the release page
3. Download the SDK example data archive from the release page
4. Unzip the archives into the cloned repository into a "prt" and "data" directory.

The final directory layout should look like this:

/esri-cityengine-sdk/
    examples/...
    license/...
    data/...
    prt/
        bin/...
        cmake/...
        doc/...
        include/...
        lib/...

This repository contains a number of source code examples. Each example contains a README with detailed instructions how to build and use it.

A quick overview:

• prt4cmd: a simple command line utility to apply rule packages onto initial shapes and generate models.
• prt4maya: wraps the SDK into a plugin for Autodesk Maya
• prt4unity: wraps the SDK into a plugin for the Unity game engine
• stlenc: demonstrates how to write a custom encoder, in this case for the STL geometry format.

Please note that the individual example READMEs may include further requirements.

• To load custom encoders built with this SDK in CityEngine, at least CityEngine 2014.0 is required.

• Windows 7 or later (32bit and 64bit)
• License for CityEngine 2013 or later
• NMake 10.0 or later (part of Visual Studio)
• CMake 3.0.0 or later (http://www.cmake.org)
• Recommended C++ Compilers for simple clients (prt4cmd example):
  • Microsoft VC 10.0 or later
• To compile SDK extensions (prt4maya example, stlenc example, custom encoders) it is required to use one of these exact C++ compiler version / boost libraries:
  • Microsoft VC10 C++ Compiler (cl.exe) 16.00.40219.01, included in Visual Studio 2010 SP1
  • Microsoft VC11 C++ Compiler (cl.exe) 17.00.61030.0, included in Visual Studio 2012 SP4
  • boost 1.53 headers and binaries
    • get the boost 1.53 headers from http://www.boost.org
    • get the boost 1.53 pre-compiled binaries from http://boost.teeks99.com (e.g. boost_1_53_0-vc64-bin.exe or boost_1_53_0-vc32-bin.exe)
    • note: if you compile boost yourself, the boost libraries need to be compiled with correct compiler (VC 10)
