IFC Engine DLL
All examples are build around the IFC Engine DLL (under Linux and OSX it is compiled as a library). The IFC Engine DLL itself is a commercial product from RDF Ltd. Both these examples and the IFC Engine DLL are not open source projects, however all source code is available (in the context of the DLL a company wide license is required). The source code for the examples is free to reuse, also in software not using the IFC Engine DLL itself.
