Beside commercial software packages there is also a number of Open Source Projects that support CityGML.


 Open Source Projects

BIMserver, Open source building information modelserver based on IFC. Has an export function from IFC to CityGML (including the GeoBIM ADE extension)
--> more information and download

libcitygml is a small and easy to use open source C++ library for parsing CityGML files in such a way that data can be easily exploited by 3D rendering applications (geometry data are tesselated and optimized for rendering during parsing). For instance, it can be used to develop readers of CityGML files in many 3D based applications (OpenGL, OpenSceneGraph, ...)
citygml2vrml is a command line utility based on libcitygml to convert CityGML files to a VRML97 representation.
libcitygml & citygml2vrml --> More information and download

CityGML2OBJs, a semantic-aware utility to convert CityGML data to OBJ, featuring decoupling of objects and conversion of attributes to colours.
val3dity, geometric validation of 3D primitives according to ISO 19107, with a web interface.
Solar3Dcity, a simple utility to estimate the yearly solar irradiation of buildings stored in CityGML.
Random3Dcity, a procedural modelling engine natively supporting CityGML, and capable of generating extensive multi-LOD representations.
--> more information and download

3D City Database, a free 3D geo database for the storage and management of virtual 3D city models based on CityGML - to be used in conjunction with Oracle 11G Spatial/Locator (or higher) or PostGIS. 3DCityDB comes with tools for CityGML import/export, export of data into spreadsheets, visualization support for KML, COLLADA, and glTF. Since version 3.2, a 3D web client which is based on the Cesium Virtual Globe is part of the project.
citygml4j, an open-source Java class library and API for the processing of 3D city models encoded in CityGML.
--> Project website www.3dcitydb.org --> Source Code --> Download of latest release --> Online demos of 3D viewer

CityGML2X is a free Java library for converting CityGML to X3D.
CityGML2XCLI is a command line interface for the free CityGML2X converter library. It lets you convert your CityGML models to X3D.

CodeSynthesis XSD, an open source, cross-platform XML data binding compiler for C++. Supports generation of the object model as well as parsing and serialization code from CityGML schemas. --> Download --> More information on using with CityGML

CityGML Plugins Sketchup™-Sketchsoftware, free and open-source plugins to export CityGML data from Sketchup™-Sketchsoftware. --> more information and download

Aristoteles, an Open Source viewer for CityGML Data. --> Download

citygml4j, an open-source Java class library and API for the processing of 3D city models encoded in CityGML.
--> Download
