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.\n\nThe project also contains a loader plugin for [OpenSceneGraph](http://www.openscenegraph.org/). It enables OpenSceneGraph (if installed) to read citygml documents for easy rendering and further graphical optimization.\n\nlibcitygml was initally developed by the 3D team of BRGM (the French leading public institution involved in the Earth Science field for the sustainable management of natural resources and surface and subsurface risks) for the research project DeepCity3D. It is now conducted as a Github open source project.\n\nIt was moved to github due to inactivity of the project on google code (https://code.google.com/p/libcitygml/).\n\n\nHow to Setup\n============\n\nThe project is based on the CMAKE build system and should be pretty straight forward to setup.\n\nDependencies:\n\nThe XercesC xml parsing library is the only requirement compiling and using libcitygml. Please use a version \u003e 3.1 compiled with an SDK that is compatible with C++11. If the library is not found by CMake use `-DCMAKE_SYSTEM_PREFIX_PATH=\u003cXercesC install path\u003e`.\n\nOpenGL is required if you want to use the tesselator provided in the project. Otherwise, you can provide another implementation by inheriting TesselatorBase, or not use tesselation. Set the cmake option \"LIBCITYGML_USE_OPENGL\" to OFF to disable the use of OpenGL.\n\nGDAL is required if coordinate transformations should be applied during paring.\nSet the cmake option \"LIBCITYGML_USE_GDAL\" to OFF to disable the use of GDAL.\n\nOpenSceneGraph is required to build the plugin.\nSet the cmake option \"LIBCITYGML_OSGPLUGIN\" to ON to enable the build of the plugin.\n\nTest Data Attribution\n=====================\n\n\nOverview over the testing data within the \"data\" directory:\n\n| Dataset                               | Attribution                                               | Source                                                                                                    |\n| -------------------------             |:---------------------------------------------------------:|:---------------------------------------------------------------------------------------------------------:| \n| data/b1_lod2_cs_w_sem.gml             | https://www.citygml.org/samplefiles/building/             | [https://www.citygml.org](https://www.citygml.org/samplefiles/)                                           |\n| data/b1_lod2_s.gml                    | https://www.citygml.org/samplefiles/building/             | [https://www.citygml.org](https://www.citygml.org/samplefiles/)                                           |\n| data/berlin_open_data_sample_data.gml | Berlin Partner für Wirtschaft und Technologie GmbH        | [Berlin Partner Download Portal](http://www.businesslocationcenter.de/berlin3d-downloadportal/?lang=en)   |\n| data/FZK-Haus-LoD0-KIT-IAI-KHH-B36-V1.gml | Institute for Automation and Applied Computer Science (IAI) / Karlsruhe Institute of Technology (KIT) | https://www.citygmlwiki.org/index.php?title=FZK_Haus |\n\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjklimke%2Flibcitygml","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjklimke%2Flibcitygml","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjklimke%2Flibcitygml/lists"}
