Library dependencies of 3DUse and their associated respective licenses

Package	License	Included headers / Notes
ASSIMP	BSD	OSGPL an LGPL variant
Boost libraries	Boost license 1.0	License seems to fall within the permissive MIT license grade/category. Packages:date_time, filesystem.
GDAL	X11/MIT style	Depends on proj.4.
GEOS	LGPLv2.1	For GDL.
LASlib	LGPLv2.1
OpenSceneGraph (OSG)	OSGPL (LGPL like)	Used sub-libraries: osgDB, osgGA, osgFX, osgQT, osgShadow, osgText,osgUtil osgViewer...
Proj.4	MIT	For GDAL.
Qt (4 or 5)	LGPLV2.1, LGPLv3, but some modules are GPL.	Core: LGPLV2 or V3, Gui: LGPLV2 or V3, QTWidgets: FIXME UNKNOWN/UNDOCUMENTED LICENSE, refer toQTWidgets module, licenses in QT

Concerning libCityGML

The code contained in src/libcitygml sub-directory is derived from libcitygml code developed by Joachim Pouderoux when he was working in the 3D team of BRGM. The headers for BRGM's original library version were preserved and now intergrated modifications as well as extensions realized by "University of Lyon".

Concerning the QT modules:

• 3D-USE stays away from the GPL poisened pill of some QT modules
• Reference gateway: licenses used in QT gateway.
• List of used packages within modules:
  • Core module: QDebug, QDir, QDirIterator, QEvent, QFile and QFileInfo, QMutex, QPluginLoader, QPointer, QQueue, QSet, QSettings, QString, QStringList, Qtime and QTimer, QTextStream,
  • Gui module (includes OpenGL): QFont, QGLWidget, QIcon, QImage and QImageReader, QInputEvent, QResizeEvent,
  • Widgets module: QDialog, QFileDialog, QGridLayout, QGraphicScene and QGraphicView, QHeaderView, QLabel, QLineEdit, QListView and QListWidget, QMainWindow, QMenu, QMessageBox, QPainter, QProgressDialog, QPushButton, QTextBrowser, QTreeWidget,
  • unknown module: QtGlobal, QtPlugin,
  • used by osgQt: QtWebKit, QtWebKitWidgets
• Obtaining the above list of used QT modules is merely a comment of the grep -rh include src ui | grep -i Q | grep -v CityGML | grep -v QtEvents | grep -v osgQt | sort | uniq command (QtEvents being used by osgQt/QGraphicsViewAdapter and osgQt belonging to OSG ).

Concerning OSGQt (OpenSceneGraph-QT extensions):

• 3DUse redistributes, without any changes and in their original versions 3.2 and 3.4, the source code of OSGQt (refer to files src/gui/osgQt/osg32/GraphicsWindowQt.cxx and src/gui/osgQt/osg34/GraphicsWindowQt.cxx
• This choice was motivated by packaging reasons (their packaging depending too much on the platform/distributions respective choices)

Concerning LASlib

LASlib sources are redistributed with 3DUse (because of lack of packaging on various platforms) in their original versions. Refer to the content of the 3DUse/externals/laslib sub-directory.

Library dependencies specific to the libCityGML component

Note: many of libCityGML library sub-dependencies could be removed

Package	License	Included headers / Notes
ASSIMP	BSD	OSGPL an LGPL variant
Boost libraries	Boost license 1.0	License seems to fall within the permissive MIT license grade/category
GLUT	Implementation dependent: MIT for FreeGLut, SGI's GLUT	For GL/glu.h
libXml2	MIT licence	-
OpenGL	BSD/X/Mozilla like	License depends on harware vendor.
OpenSceneGraph (OSG)	OSGPL (LGPL like)	Used sub-library: osgDB.
Qt (4 or 5)	LGPLV2.1, LGPLv3, but some modules are GPL!.	QDir, QDirIterator, QFile, QString.

Warning: grep -rih "#include" src/libcitygml | sort -rn | uniq only tells one part of the story because it includes headers from non sub-directories like utils, DataStrcutures...

• src/gui/osg/osgCityGML.cpp is copyrighted "2010 Joachim Pouderoux, BRGM"
