From FreeCAD Documentation

The geometry that appears in the 3D views of FreeCAD is rendered by the Coin3D library. Coin3D is an implementation of the Open Inventor standard. The OpenCASCADE software also provides the same functionality, but it was decided at the very early stages of FreeCAD not to use the built-in OpenCASCADE viewer, but rather switch to the more performant Coin3D software. A good way to learn about that library is the book Open Inventor Mentor.
