IfcPlusPlus

Description
IFC++ or IfcPlusPlus is an open source (MIT license) library for reading and viewing IFC files from the IfcQuery project.

While the library can be used for different purposes, the most useful component is the example viewer, which can be used to compare the performance of other viewers and editors of IFC data, like Blender and FreeCAD, which use IfcOpenShell.

The example viewer uses Qt and the OpenSceneGraph library to convert the implicit geometry in IFC files into explicit geometry on screen.

Installation
IfcPlusPlus must be compiled from source.

It requires the OpenSceneGraph library for visualization, as well as the development files for Boost and Qt 5. If you have already compiled FreeCAD in Linux, or IfcOpenShell, you may already have all the prerequisites, except for the OpenSceneGraph development files.
