3D view: Difference between revisions

Other languages:

The 3D view of FreeCAD is an instance of a Coin3D scenegraph. Coin3D is a library that implements the OpenInventor 2.1 scene description standard.

By the default the 3D view shows a small widget with coordinate axes, and the navigation cube also with a coordinate axes; the grid can be displayed and configured using the Draft Workbench.

Since FreeCAD uses Qt as its graphical toolkit, FreeCAD uses the Quarter library to tie Qt with Coin3D.

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