mne.viz.set_3d_backend

mne.viz.set_3d_backend(backend_name, verbose=None)

Set the 3D backend for MNE.

The backend will be set as specified and operations will use that backend.

Parameters:

backend_namestr

The 3d backend to select. See Notes for the capabilities of each backend ('pyvistaqt' and 'notebook').

Changed in version 0.24: The 'pyvista' backend was renamed 'pyvistaqt'.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

old_backend_namestr | None

The old backend that was in use.

Notes

To use PyVista, set backend_name to pyvistaqt but the value pyvista is still supported for backward compatibility.
