• Open Source GML3 3D viewer application Aristoteles (Version 1.1, zip archive, 26.8 MB) developed by the Institute for Cartography and Geoinformation, University of Bonn. Java 1.5 is needed (Java3D libraries are included in the package). Aristoteles is able to fetch CityGML models directly from Web Feature Services by a graphical user interface. A couple of WFS that are accessible from the Internet can be preselected. Aristoteles is not restricted to CityGML files; it can visualize arbitrary GML3 files (like the German cadastre standard ALKIS/NAS). It can also be used to validate GML3 instance documents. Please note that there are some issues concerning the visualization of textured models with version 1.1. However, version 1.1 is capable to handle CityGML application domain extensions.
  The previous version can still be found here (1.0 built 20, zip archive, 27 MB). Further information can be found on the Aristoteles project homepage.
• Free CityGML viewer application LandXPlorer developed by the company 3DGeo and the Hasso-Plattner-Institute of the University of Potsdam. Further information and download are available here (company 3DGeo) and here (HPI, University of Potsdam). The latest version is 2.6.0, it already supports the new CityGML version 0.4.0.
