 Welcome

DeepCity3D project intends to develop application-adaptive 3D visualisation tools that integrate for the first time underground data and City models (provided in standardised formats) with advanced functionalities to support decision making in Urban Planning, Construction Companies, Insurance Companies, Architects, Environmental Protection. 

DeepCity3D is joint research project of BRGM and Fraunhofer IGD selected by the "Programme Inter Carnot-Fraunhofer PICF 2009". The project, started in september 2009, is funded by the french ANR and the german BBF.

DeepCity3D user workshop

A user requirements workshop for the DeepCity3D project will take place on February, 22nd 2011 at the Fraunhofer IGD in Darmstadt, Germany. The CityServer3D is used in this project to manage 3D city models and to visualize underground structures like gelogy, tunnels, basements, and others. The workshop will be held in German.

The event will be a good opportunity for domain experts to share their experience in the following areas:

  • Semantic integration of 3D city models and underground structures
  • Unique visualization techniques to display this data in an integrated way
  • New ways to navigate through underground in 3D
  • Support of analyses and simulations

Apart from that, already elaborated design concepts will be presented.

 

libCityGML opensource library

CityGML (City Geography Markup Language) is an XML-based schema for the modelling and exchange of georeferenced 3D city and landscape models that is quickly being adopted on an international level.

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, ...) Most metadata are not lost, they are available through a per-node hashmap.

libcitygml is developed by the team BRGM under the DeepCity3D project to setup a set of WPS (Web Process Services) able to manipulate CityGML files.
