3D view

The 3D view of FreeCAD is an instance of Coin3D, a library that implements the OpenInventor standard.

Since FreeCAD uses Qt as it's graphical toolkit, FreeCAD uses the Quarter library to tie Qt and Coin3D.

It is also possible to interact directly with the 3D view from the Python console by using the Python library Pivy.

For more information see the power user documentation:

• Third party libraries
• Scenegraph, usage of Coin3D.
• Pivy, usage of Coin3D from the Python console.
