Building libcityGML

Download from Google code: http://code.google.com/p/libcitygml/ (version 0.1.4 as on 2011/05/12)

svn checkout http://libcitygml.googlecode.com/svn/trunk/ libcitygml-read-only

Configure with cmake then generate makefiles (add x86_64 architecture for compatibility with OSG)

ccmake .

Be careful to set the following configuration variables :

  • CMAKE_BUILD_TYPE: Release
  • LIBCITYGML_DYNAMIC: ON

Test whether libCityGml is working

bin/citygmltest <path to citygml file>

Creating the OSG plugin

Copy FindCityGML.cmake and FindXerces.cmake from libcitygml/CMakeModules to $(OSG_SRC_DIR)/CMakeModules

cp CMakeModules/FindCityGML.cmake ../OpenSceneGraph-2.9.9/CMakeModules/
cp CMakeModules/FindXerces.cmake ../OpenSceneGraph-2.9.9/CMakeModules/

Copy all files from libcitygml/test/osgplugin/ to $(OSG_SRC_DIR)/src/osgPlugins/citygml

mkdir $(OSG_SRC_DIR)/src/osgPlugins/citygml
cp libcitygml/test/osgplugin/* $(OSG_SRC_DIR)/src/osgPlugins/citygml

Add the following line to $(OSG_SRC_DIR)/src/osgPlugins/CMakeLists.txt

ADD_SUBDIRECTORY(citygml)

go back to main OpenSceneGraph directory, re-run cmake to generate new makefiles (including the one for the libcitygml plugin), then make and sudo make install. Test by loading a citygml file with osgviewer. It should now open.

Caution: with this method, CityGML files are identified by a .citygml extension. Files with .gml extensions will not load.
